Chapter 4 global action to reduce greenhouse gas emissions

As the evidence and risks posed by global warming have become clearer (Chapter 2), global action to reduce greenhouse gas emissions has steadily increased.

Ninety-nine countries, covering over 80 per cent of global emissions, have 2020 emissions reduction goals. Countries are implementing a range of policies to meet these goals, including renewable energy targets, emissions trading schemes, tax incentives for improved energy efficiency and fuel economy and electricity generation emissions standards.

The current level of action, measured by the 2020 goals, is not sufficient to put the world on track to limit warming below 2 degrees relative to pre-industrial levels. But the level of action has steadily increased over the last 20 years and accelerated recently; more countries are taking on targets and more emissions reduction policies are in place than ever before. The two largest emitters of greenhouse gases – China and the United States – are both stepping up their actions to reduce emissions, separately and together. These measures could have a significant impact on global emissions reductions.

The next few years will be a critical time as countries decide whether to strengthen their 2020 emissions reduction goals under the United Nations Framework Convention on Climate Change (due 2014) and negotiate a new post-2020 climate agreement (due 2015).

Chapter 3 set out a global budget that is consistent with limiting global warming to 2 degrees. Climate change is a global problem and developing a solution will require action by all countries; in particular; major emitting economies like Australia.

Chapter 4 sets out the global context and assesses international trends in emissions reduction activities. Chapter 5 builds on this assessment to consider Australia’s role in international action and how the international context should be factored into the Authority’s recommendations for Australia’s emissions reduction goals.

Chapter 4 discusses:

  • the Authority’s approach to assessing global action to reduce emissions;
  • progress under the United Nations Framework Convention on Climate Change (UNFCCC) and other international forums;
  • countries’ 2020 emissions reduction goals, including their aggregate effect on global emissions;
  • climate policies and measures in other countries with a special focus on actions of the world’s two largest emitters, China and the United States; and
  • post-2020 global climate action.

4.1 The Authority’s approach to assessing global action

The Authority considers that global trends in emissions reductions targets and policies provide the best picture of global action.

Global action is complex – some countries are taking ambitious action now, some are doing less, and the pattern is likely to vary over time. In such circumstances, broad trends are a better indicator than the isolated actions of any individual country at a particular point in time. The exceptions are China and the United States, which together constitute over one-third of global emissions. The Authority has considered the actions of these two countries in some detail given their significant effect on climate change.

In assessing global trends, the Authority has considered both:

  • targets and commitments to future action; and
  • domestic policies and measures to reduce emissions.

Both targets and policies are important. Targets provide a useful indication of countries’ intentions; however, targets are, by their nature, aspirational. They can only be met if they are backed by policies and measures that make emissions reductions happen. Targets and policies are mutually supportive – targets can help drive the implementation of climate change policies, while successful policies can make stronger targets more achievable.

The Authority has focused its analysis on emissions reductions outcomes – it has not discriminated on the basis of the form of a commitment (legally binding or not) or where it is inscribed (internationally or domestically). The Authority has therefore taken into account progress under the UNFCCC, but it has also looked beyond – to domestic action and other international forums. While legal form can be an important indicator of how likely action is to occur, ultimately it is emissions reductions that are important for limiting global warming to below 2 degrees.

The Authority’s focus on emissions reduction outcomes was supported by a number of stakeholders, including the Business Council of Australia (Issues Paper submission, p. 8).

Primary sources of information about global action include the United Nations, the World Resources Institute and the Australian Government. In some cases, different data sets have been used for the international analysis than in other chapters of this report to allow for consistent data sets over a wide range of countries. Appendix B provides further details on the data sources used in the Authority’s analysis. 

4.1.1 Key countries considered in the Authority’s analysis

The Authority has chosen a set of key countries to illustrate trends in global action throughout the draft report. The set is listed at Table 4.1 and includes countries with similar levels of development to Australia, major emitting economies and Australia’s trading partners and neighbours. The selection takes into account stakeholder feedback by including developed and developing countries, OECD countries, and countries with similarly sized economies and economic structure to Australia (see Origin Energy submission, p. 3; Business Council of Australia submission, pp. 10–11). It also includes four of Australia’s top five trading partners in 2012.

A number of stakeholders emphasised the relevance of considering trade competitors’ actions when setting Australia’s target (including the Australian Industry Greenhouse Network submission, p. 4 and the Business Council of Australia submission p. 14). Identifying trade competitors for the whole economy is difficult as competitors vary widely across sectors, across activities and over time. To the extent that Australia’s competitors are also its main trading partners, they are included in Australia’s key country mix. Legislation currently requires the Productivity Commission to consider which countries constitute Australia’s trade competitors as part of its first review of the Jobs and Competitiveness Program, scheduled in the Clean Energy Act 2011 (Cth) to be conducted in the 2014–15 financial year.

Table 4.1 also describes emissions and development data for each country. Emissions data are presented both as a per cent of global emissions and in per person terms (in tonnes of carbon dioxide equivalent, tCO2-e). The Human Development Index (HDI) is used to provide an indication of countries’ development levels. The HDI is a measure of development compiled by the United Nations Development Programme which combines indicators of life expectancy, educational attainment and income.

4.2 Progress under the United Nations Framework Convention on Climate Change

The UNFCCC is the centrepiece of the international climate change framework. The UNFCCC has facilitated significant progress to address climate change – from an acknowledgement by all countries that climate change is a problem (1992) to emissions reduction goals by developed countries (1997) to emissions reduction goals by all major emitting economies in 2009 (major emitting economies are defined as countries that participate in the Major Economies Forum).

Figure 4.1: Countries with international emissions goals under the UNFCCC

This figure shows the growth of countries with emissions reduction goals under the UNFCCC. In 1990 there were no countries with emissions reduction goals. By 1997, 37 countries had emissions reduction goals. In 2013, 99 countries have emissions reduction goals.

Source: UNFCCC (Kyoto Protocol in 1997, Nationally Appropriate Mitigation Actions and Economy-wide Reduction Targets in 2013)

The UNFCCC entered into force in 1994 and, with 195 Parties, it has one of the most universal memberships of any international treaty.

The UNFCCC reflects near-global agreement on a number of key matters:

  • an objective to ‘prevent dangerous anthropogenic interference with the climate system’;
  • that all Parties should formulate and implement national programs to mitigate climate change;
  • that all Parties should report on their emissions and national action through inventories and national communications; and
  • that developed country Parties should provide support to assist developing countries take action to address climate change and adapt to it.

The Kyoto Protocol to the UNFCCC was adopted in 1997, following the Intergovernmental Panel on Climate Change (IPCC) Second Assessment Report, which found that greenhouse gas emissions could cause changes to the climate unprecedented in human history and that climate change would be virtually irreversible.

The Protocol built on the general commitments of the UNFCCC by establishing specific targets for developed (Annex I) countries to reduce their greenhouse gas emissions. For most Annex I Parties, these targets are expressed as a percentage reduction from a 1990 baseline over the period 2008–2012 (the ‘first commitment period’).

The 2007 IPCC Fourth Assessment Report concluded that the climate was changing faster than predicted in previous reports. This report was closely followed by the 2007 Bali Action Plan under the UNFCCC, which began a new negotiating process to discuss mitigation action by all countries, including the United States (which did not ratify the Kyoto Protocol) and developing countries (which do not have emissions reduction commitments under the Kyoto Protocol).

The Bali Action Plan negotiations were expected to conclude at the 2009 Copenhagen Conference with a mandate to negotiate a new legal agreement. In 2009, however, Parties were unable to come to final agreement, instead ‘noting’ the Copenhagen Accord. While falling short of expectations, the Accord set out significant new steps, which were formally agreed by Parties in 2010 at the Cancun Conference:

  • an objective to reduce global emissions so as to ‘hold the increase in global temperatures below 2 degrees Celsius’ together with a 2013–15 review to assess the adequacy of this goal in the light of current science;
  • specific 2020 pledges to reduce or limit emissions by most developed and developing countries. Currently 99 countries have made pledges;
  • more robust measurement, reporting and verification arrangements for emissions and emissions reductions; and
  • short- and long-term financial commitments by developed countries to assist developing countries.

The 2011 Durban Conference continued work to clarify countries’ 2020 pledges, as well as setting out a pathway for a post-2020 agreement. This post-2020 agreement will be applicable to all countries, and is due to be concluded by 2015 to come into effect by 2020.

The 2012 Doha Conference saw the formal adoption of amendments to the Kyoto Protocol to create a second commitment period from 2013–2020. Thirty-seven Annex I Parties agreed to take on a target – Australia, Belarus, all 28 European Union members, Iceland, Liechtenstein, Monaco, Kazakhstan, Norway, Switzerland and Ukraine. Russia, Japan and New Zealand did not take second commitment period targets. Canada has formally withdrawn from the Protocol. Importantly, all the Annex I Parties that do not have targets under the second commitment period of the Kyoto Protocol, including the United States, have 2020 targets under the UNFCCC.

Countries are currently reviewing the level of global ambition – both in the context of increasing the strength of Kyoto Protocol emissions reduction commitments, and more broadly under the UNFCCC. Both these reviews will take place in 2014, informed by the IPCC Fifth Assessment Report, which will be completed in 2014.

Negotiations have also begun on the form and content of a post-2020 agreement, which is due to be negotiated by 2015. To work towards this new agreement and aim to increase global effort on climate change, the United Nations Secretary General will convene a leaders’ summit on climate change in September 2014.

The UNFCCC is an important source of information about global action, including national inventories of emissions and national communications by countries explaining what they are doing to address climate change. The 2020 emission reduction goals put forward by countries under the UNFCCC (discussed in Section 4.3) also provide a useful indication of countries’ future intentions.

Recently, there has been much attention on the fact the UNFCCC has not yet agreed on a new treaty with legally binding emissions reduction commitments by all countries. ‘Legally binding’ agreements may provide greater assurance that countries fulfil their committed action. However, they are not the only indicator of action. Significant progress has been made under the UNFCCC beyond a new treaty, including emissions reduction goals and systems to measure, report and verify emissions and emissions reductions.

4.2.1 Other international initiatives

There are a range of international initiatives underway aimed at facilitating climate change action outside of the UNFCCC. These allow countries to exchange practical ideas about reducing emissions and include:

  • research and development into low-emissions technologies, such as carbon capture and storage, renewable energy and approaches to reduce emission from agriculture;
  • commitments to reduce or phase out fossil fuel subsidies including under the G20;
  • linking of emissions trading schemes, such as those of the EU and Norway, and proposed links between California and Quebec, and Switzerland and the EU;
  • bilateral and regional agreements targeting particular areas of climate change policy; for example, short-lived gases such as methane and hydrofluorocarbons through the Climate and Clean Air Coalition, and carbon markets through the World Bank Partnership for Market Readiness.

Other international initiatives that reduce global warming include the Montreal Protocol on Substances that Deplete the Ozone Layer (The Montreal Protocol), which was designed to ‘phase out’ a range of gases to protect the ozone layer by destroying them safely and replacing them with substitutes. Many of the gases covered by the Montreal Protocol drive global warming as well as damaging the ozone layer, so the phase-out has had a significant positive impact on climate change.

Emissions from international aviation and maritime activities are currently not counted towards individual country emissions or targets under the UNFCCC. Both have nearly doubled in the last 10 years. Discussions to reduce emissions from these sectors occur in the International Maritime Organization and the International Civil Aviation Organization.

Appendix B provides further information on international initiatives outside the UNFCCC.

4.3 2020 emissions reduction targets

Ninety-nine countries, including Australia, have committed to 2020 emissions reduction targets and actions under the UNFCCC. These countries account for over 80 per cent of global emissions and 90 per cent of the global economy. The UNFCCC documents listing countries’ pledges are available on the UNFCCC website.

In many of these countries, these pledges are also included in domestic legislation and national planning documents. Table 4.2 shows the 2020 emissions reduction targets of key countries, both international pledges and, where relevant, additional domestic targets or commitments.

Table 4.2: 2020 Emissions reduction targets of key countries

Country International and domestic 2020 emissions reduction targets*
Australia International: 5 per cent, up to 15 per cent or 25 per cent relative to 2000 (5 per cent unconditional).
China International: Lower carbon dioxide emissions per unit of GDP by 40–45 per cent relative to 2005. Domestic: China’s 2020 target has been incorporated in its medium and long-term economic and social development plans as a binding target. China has an interim carbon intensity target under its 12th Five-Year Plan (2011–2015).
United States International: In the range of 17 per cent relative to 2005. Domestic: This goal is included in President Obama’s 2013 Climate Action Plan.
European Union (28 member states) International: 20 per cent relative to 1990. Conditional target of 30 per cent relative to 1990. Domestic: Many European Union countries have climate targets included in legislation or national plans. The European Union also has agreed to a formal ‘burden sharing arrangement’ for some of its collective climate targets.
India International: reduction in emissions intensity (emissions per unit of GDP) by 20–25 per cent relative to 2005 (excluding agriculture).
Japan International: 25 per cent relative to 1990.**
Germany International: 20 per cent relative to 1990, as part of EU target. Domestic: The German Government has included in legislation a national target of reducing greenhouse gas emissions by 40 per cent by 2020 relative to 1990.
Indonesia International: 26 per cent relative to ‘business as usual’. Domestic: Indonesia’s National Action Plan for Greenhouse Gas Emission Reduction states Indonesia could reduce emissions up to 41 per cent by 2020 relative to business as usual with international support.
Canada International: 17 per cent relative to 2005. Canada has withdrawn from the Kyoto Protocol, but maintains this target under the UNFCCC.
Republic of Korea International: 30 per cent relative to ‘business as usual’. Domestic: The 2020 goal is included in Korea’s 2010 Framework Act on Low Carbon, Green Growth.
United Kingdom International: 20 per cent relative to 1990, as part of EU targets. Domestic: The UK has a domestic 2020 target of 34 per cent below 1990 levels. It also has a series of binding carbon budgets under its Climate Change Act for the period 2008–2027. The 2027 carbon budget represents emissions of 50 per cent relative to 1990.
South Africa International: 34 per cent relative to ‘business as usual’, and 42 per cent relative to ‘business as usual’ by 2025. Domestic: The 2020 goal is referred to in South Africa’s 2011 National Climate Change Response.
New Zealand International: Unconditional target of 5 per cent relative to 1990. Conditional target of 10–20 per cent relative to 1990.
Norway International: 30 per cent relative to 1990. Conditional target of 40 per cent relative to 1990.

* Many countries’ targets are conditional on the extent of climate action in other countries. The conditions can be found in UNFCCC submissions compiled here for developed countries and here for developing countries.
Domestic action included in this table covers targets included in domestic legislation, national planning documents and other official government plans.

It is too early to definitively say whether countries will meet their 2020 targets. Many countries are in the process of implementing policies for which the actual mitigation effect is not yet known (for example, Korea’s legislated carbon price and South Africa’s carbon tax). Other countries, including Norway, are intending to meet their targets through using fast-acting policies closer to 2020, such as the planned purchase of overseas emissions units. Countries’ energy mixes can also change rapidly for non-climate-centred reasons and make it either easier or harder to achieve a target, as demonstrated by the United States gas boom and Japan’s nuclear disaster. Finally, ambition of targets is linked to achievability. Countries with strong targets may be less likely to achieve them, although they may still reduce their emissions significantly.

With those important caveats, it is clear that countries are generally taking their targets seriously and bringing in policies to meet them. There is also heartening precedent – most countries that have first commitment period targets listed in Annex B of the Kyoto Protocol appear to be on track to comply with them (two exceptions are the United States, which did not ratify the Kyoto Protocol, and Canada, which withdrew from the Protocol in 2012).

Importantly, the United States and China (the world’s top two emitters, responsible for about 37 per cent of global emissions) are both capable of meeting or exceeding their 2020 targets. The World Resources Institute assessed US policy in 2013, and concluded it could meet its target by using executive powers of the sort recently announced by President Obama (WRI 2013a). Similarly, the Climate Action Tracker Project, run by a coalition of European climate research groups, concluded that China was on track for its 2020 target: ‘Recent energy and emissions data combined with China’s 12th Five-year plan announced in March 2011 indicate that China is set to not only meet its [2020] emissions intensity pledge, but is likely to go beyond it.’ (Climate Action Tracker, 2011).

4.3.1 Aggregation of 2020 targets

A range of studies has attempted to quantify the aggregate emissions reductions associated with the current 2020 UNFCCC emissions reduction pledges. There are high degrees of uncertainty associated with these studies; however, most find that while current 2020 commitments will reduce emissions below business-as-usual projections, they are not sufficient to put the world on track to meet the below 2 degrees global goal.

The United Nations Environment Programme (UNEP) Emissions Gap report series (published annually) is one of the most comprehensive studies aggregating commitments. The report series estimates the difference, or ‘gap’, between the level of projected global greenhouse gas emissions with current 2020 pledges, and the level climate science recommends to limit future temperature increases to below 2 degrees.

The most recent UNEP report finds that the emissions gap for a likely chance of tracking below 2 degrees is 8 to 13 Gt CO2-e (a likely chance is defined by UNEP as 67 per cent). This is equivalent to around 14 to 24 times Australia’s entire annual emissions.

Importantly, the report finds that it is technically feasible to limit temperature increases to below 2 degrees with either greater pre-2020 action or post-2020 action; however, it notes that increasing action post-2020 will be more costly than acting earlier due to lock-in of emissions-intensive infrastructure (UNEP 2012).

4.4 Countries’ domestic policies and measures

Domestic action to address climate change has increased over time. GLOBE notes that in 2012 there were a total of 286 climate change-related laws in the 33 study countries (GLOBE International 2013) – see Figure 4.2.

Figure 4.2: Total climate change laws in GLOBE country studies, 1963–2012

This figure shows the growth of countries laws about climate change, as reported in the GLOBE international report series. In 1963, no countries had climate laws. The number of laws grew steadily, from around 30 in 2001 to nearly 300 in 2011.

Source: Globe 2013

All the major emitting economies now have domestic policies and measures to support their 2020 emission reduction targets. Policies include incentives for renewable energy, energy efficiency standards, emissions trading schemes and emissions performance standards in electricity generation and transport. Particular approaches vary from country to country depending on its development level, economic structure and the targeted sector or desired response.

Table 4.3 describes the climate actions of key countries in different sectors. Most countries, including China and the United States, have policies in all these sectors. An expanded version of this table is in Appendix B.

Table 4.3: Policies and measures of key countries

Type of policy Example of policies Coverage
Energy supply Renewable energy targets, feed-in tariffs All key countries have some or multiple energy supply policies in place
Energy demand Appliance and building energy efficiency standards All key countries have some or multiple energy demand policies in place
Transport Mandatory vehicle emissions, pollution or fuel efficiency standards; incentives for renewable fuel production Nearly all key countries other than Australia and New Zealand have some form of mandatory vehicle standards; more than half have greenhouse gas emissions standards
Carbon pricing Taxes or emissions trading schemes Most key countries have policies in place at national or subnational level; others including the Republic of Korea and South Africa are planning to introduce policies in 2015

 

4.4.1 Climate change action in China and the United States

The two countries with the largest impact on global climate change action are China and the United States. Together, they were responsible for over a third of the world’s emissions in 2009 (refer to Box 4.1).

Both countries are acting on climate change. They have put in place policies and measures to address climate change, and are stepping up these efforts1.

Action in China

China is acting on climate change, including by investing in renewable energy, imposing stringent energy performance standards and establishing emissions trading schemes. Box 4.2 provides a snapshot of China’s climate change action.

China has integrated climate change as a core part of its economic planning. China’s climate targets are included in its central economic policy document for 2011–15, the 12th Five-Year Plan. The Five-Year Plan contains targets for energy intensity (energy consumption per unit of GDP: 16 per cent reduction by 2015 relative to 2010 levels) and CO2 emissions per unit of GDP (17 per cent reduction by 2015 relative to 2010 levels). Achieving these targets would put China on track to meet its international commitments.

China has shown its ability to set and achieve environmental targets. Between 2006 and 2010, China reduced its energy intensity by 19.1 per cent from 2005 levels (The Network for Climate and Energy Information, 2012), and the national government reported that it had closed nearly 500 smaller and less efficient power plants.

China is a world leader in renewable and low-carbon energy. In 2012, $US67 billion in renewable energy (more than a quarter of the world total) and wind power generation capacity grew faster than coal-fired generation capacity (REN21, 2013). It also has the world’s largest installed renewable generation capacity at 90 gigawatts (excluding hydropower, Australia’s comparable renewables capacity was about 5 gigawatts in 2012). The power China produces from wind is now larger than the power it obtains from nuclear (REN21, 2013).

In response to air pollution, China has announced a target of capping coal consumption of 4 billion tonnes of coal equivalent per year, with a parallel cap on coal output of 3.9 billion tonnes in 2015. Although these caps are non-binding, they clearly signal China’s intention to address its energy use and environmental problems. China also tightened its fuel economy standards for passenger vehicles in 2013.

China is implementing market mechanisms to reduce its emissions. Emissions trading commenced in Shenzhen in June 2013, covering more than 600 companies and approximately 31 Mt of CO2 emissions (about the size of South Australia’s annual greenhouse gas emissions). Pilot emissions trading schemes are proposed to start over the next few years in six other cities and provinces Beijing – Chongqing, Shanghai, Tianjin, Guangdong and Hubei. These seven areas make up a third of China’s economy and about a fifth of its energy use (DIICCSRTE, 2013). China plans to start a national emissions trading scheme after 2015.

Action in the United States

US emissions have dipped downwards in recent years, partly due to slower economic growth and a boom in gas production that has reduced coal-fired electricity production. Momentum for stronger climate policy is also building in the United States.

In June 2013 President Obama announced a new Climate Action Plan, in a speech that mentioned Hurricane Sandy and the necessity for immediate federal climate leadership. The Plan aims to reduce US emissions, prepare for the domestic impacts of climate change and increase international climate cooperation. It uses the President’s executive powers to increase regulations on new and existing power plants, accelerate renewable energy development on public land, and direct federal agencies to use more renewable energy and increase their energy efficiency. The combined effect of these measures could be significant – the power plant regulations could prevent the construction of new coal-fired power plants without carbon capture and storage technology.

Strict vehicle fuel economy and emissions standards introduced in 2011 will drive large reductions in emissions (transportation makes up nearly one-third of total US emissions). The US Government estimated that the new standards would save 6 000 Mt of CO2-e between 2011 and 2025, more than 10 times Australia’s 2012 total emissions. The US Energy Information Administration (2013) estimates that there are already two million hybrid vehicles in the United States, and an additional nine million ‘alternative fuel’ vehicles capable of using electricity, ethanol, liquid petroleum gas or natural gas.

The United States has been at the forefront of investment in renewable energy for the past decade. Renewable energy investment in the United States totalled US$36 billion in 2012 and invested $US36 billion in 2012. It is a close second to China in renewable capacity, with 86 gigawatts installed (REN21, 2013.)

Much action on climate change in the United States is happening at state and local level. Twenty-nine states have adopted greenhouse gas reductions targets or limits, with varying stringency. Nine north-eastern states have in place an emissions trading scheme for their power sector that began in 2009 – the Regional Greenhouse Gas Initiative. California has a separate emissions trading scheme which began in 2013. The scheme will eventually cover most of California’s emissions, which comprise around 7 per cent of total US emissions – equivalent to about 80 per cent of Australia’s annual emissions.

China–US cooperation

The United States and China have committed to work together on climate change.

In June 2013, President Obama and President Xi reached a bilateral deal to work to phase down the consumption and production of hydrofluorocarbons – potent greenhouse gases used in refrigeration and air conditioning – under the Montreal Protocol.

At the two countries’ annual Strategic and Economic Dialogue in July 2013, China and the United States announced renewed cooperation in five areas:

  • reducing emissions from heavy-duty and other vehicles
  • carbon capture and storage demonstration
  • increasing energy efficiency in buildings, industry and transport
  • improving greenhouse gas data collection and management; and
  • promoting smart grids.

The United States and China are cooperating on climate change at subnational levels. The US state of California and the Chinese municipality of Shenzhen are working together on air quality. Both regions have emissions trading schemes in place, and have also agreed to share policy design and early experiences from these schemes.

4.5 Post-2020 framework and goals

To achieve the below 2 degrees goal, global action needs to further accelerate before and after 2020. International negotiations to establish a post-2020 framework for action on climate change have begun.

In the UNFCCC, the new agreement is due to be negotiated by 2015 and to come into effect in 2020. Countries including Australia are expected to begin putting forward post-2020 goals in the UNFCCC, possibly as early as 2014.

Australia can influence the development of this framework in the UNFCCC, especially in the context of the new agreement negotiations. The Authority considers it important that the new agreement encourages countries to reduce their emissions and ensures their actions are transparent and verifiable. Facilitating trade of credible emissions reductions could also add to the speed and effectiveness of a global response to climate change.

Alongside the UNFCCC negotiations towards a new agreement, many countries have begun internal policy processes to consider medium-term targets such as 2025 or 2030. Several countries have also set domestic 2050 goals to guide their progress, including the European Union, the United Kingdom, New Zealand, Mexico, Japan and Norway. Table 4.4 sets out current post-2020 goals in key countries. More countries are expected to announce post-2020 goals as international and domestic processes advance.

Table 4.4: Post-2020 emissions reduction targets of selected key countries

Country Post-2020 domestic target in place Considering additional targets
Australia 2050
80 per cent below 2000 levels.
 
United States 2050
In 2009, President Obama committed to a goal of 83 per cent below 2005 levels.
 
European Union (28 member states) 2050
80–95 per cent below 1990 levels.
Considering 2030 targets, decision expected late 2013. Roadmap to 2050 planning document contains reduction targets of 40 per cent by 2030 and 60 per cent by 2040, both relative to 1990 levels.
Japan 2050
80 per cent below 1990 levels included in its Fourth Basic Environment Plan.
 
Germany 2050
Germany contributes to the EU 2050 targets. It has adopted the EU goal of 80–95 per cent in its energy blueprint.
Considering 2030 targets with EU, decision expected late 2013. Legislation passed in 2010 sets out a road map to 2050, with indicative targets below 1990 levels: 40 per cent by 2020, 55 per cent by 2040, 70 per cent by 2040 and 80–95 per cent in 2050.
United Kingdom 2050
The UK contributes to the EU 2050 targets. 80 per cent below 1990 levels The UK’s goal is supported by legislated carbon budgets from 2008 to 2027. The 2027 carbon budget represents emissions of 50 per cent below 1990 levels.
Considering 2030 targets with EU, decision expected late 2013.
South Africa 2025
42 per cent below business as usual levels set in South Africa’s National Climate Change Response.
South Africa has a ‘peak, plateau and decline’ strategy where its emissions peak between 2020 and 2025, plateau for around 10 years and then fall.
New Zealand 2050
50 per cent below 1990 levels.
 
Norway 2050
Carbon neutrality (reduce global greenhouse gas emissions by the equivalent of 100 per cent of its own emissions).
If an ambitious global climate agreement is achieved, in which other developed countries also take on extensive obligations, Norway has stated it will undertake to achieve carbon neutrality by 2030.

 

* Many countries’ targets are conditional on the extent of climate action in other countries. The conditions can be found in UNFCCC submissions compiled here for developed countries and here for developing ones.
Sources are either the UNFCCC submissions or country websites. Key countries not in this table have not yet announced post-2020 goals.

Draft conclusion

C.3 Although the current level of global action is not yet on track to meet the below 2 degree global goal, there is a significant and accelerating trend to global action to reduce greenhouse gas emissions. All the major emitting economies, including China and the United States, have 2020 emissions reduction goals backed by domestic policies and measures.
