BusinessGreen runs down the intended national emissions pledges already submitted by countries ahead of a global deal to cut carbon emissions
With the Paris climate talks fast approaching, the nearly 200 countries due to attend the United Nations summit have been asked to submit the national climate action plans and emissions pledges that are expected to provide the basis of any deal.
Nearly 180 countries have officially filed their pledges under the system of so-called Intended Nationally Determined Contributions (INDCs). This includes some of the world's biggest economies, including the EU and the US. Drawing on recent analysis from PwC, BusinessGreen takes a look at some of the most important pledges and what they could mean for those countries' policy and investment landscapes.
Afghanistan has pledged to cut emissions by 13.6 per cent by 2030 compared to a business-as-usual scenario, but this is dependent on international finance.
Albania has promised an 11.5 per cent reduction in carbon emissions by 2030, compared to business-as-usual. The country's INDC pledge contains a long-term plan to cut greenhouse gas emissions to two tonnes per capita by 2050.
Algeria - The North African country pledged to curb carbon emissions by at least seven per cent compared to business-as-usual (BAU) levels by 2030, rising to 22 per cent depending on the level of international financial support it receives. It also plans to generate 27 per cent of its electricity from renewable sources by 2030, and cut its energy consumption by nine per cent through initiatives such as a national housing insulation programme.
Andorra pledged a 37 per cent reduction in greenhouse gas emissions from a business-as-usual scenario by 2030.
Antigua and Barbuda committed to a series of conditional and unconditional targets to reduce emissions, including preparing buildings for climate extremes and increasing renewable power production.
Armenia has pledged to curb per capita emissions to 5.4 tonnes between 2015 and 2050.
Australia - pledged to reduce emissions by 26 to 28 per cent by 2030 based on 2005 levels covering all sectors of the economy, including land use emissions.
Azerbaijan has promised a 35 per cent cut in emissions by 2030, compared to 1990 levels. This still leaves room for emissions to grow slightly, as they are currently about 40 per cent below 1990 levels.
Bangladesh has promised unconditionally to reduce its emissions in the power, transport and industry sectors five per cent by 2030, against business-as-usual levels. It has made a further promise to reduce emissions by 15 per cent, provided more international support is made available to boost the country's clean development.
Barbados pledged emissions cuts of 44 per cent by 2030 against business-as-usual. This is the equivalent of a 23 per cent cut in absolute terms from 2008.
Belarus pledged to cut emissions by 28 per cent by 2030, compared to 1990 levels.
Bhutan has reiterated its pledge to remain carbon neutral, which it first announced in 2009. It also repeated its pledge to keep 60 per cent of its national land forested.
Bolivia announced a range of highly ambitious goals, and said capitalism must be "destroyed" for a lasting solution on climate change. It pledged to end illegal deforestation by 2020 and boost the share of renewable energy to 79 per cent by 2030 from 39 per cent in 2010.
Bosnia and Herzegovina - Pledged to cut emissions by three per cent by 2030 compared to a business-as usual scenario, but this would rise to 23 per cent with international financial support.
Botswana pledged to cut emissions by 15 per cent by 2030, using 2010 as the base year.

Cameroon has pledged to curb the growth of its carbon emissions by 32 per cent by 2035 against business-as-usual levels. This equates to a real increase in emissions of 71 megatons of CO2 between 2010 and 2035, as opposed to 104 megatons under business-as-usual. The main reductions will come from reducing the environmental impact of the country's agricultural and energy production sectors.
Canada has proposed to cut its emissions by 30 per cent against 2005 levels by 2030. PwC suggests this target is actually more ambitious than the EU and US targets, despite reports to the contrary. It will require Canada to decarbonise at a rate of 3.9 per cent per year, which is close to what France achieved in the 1980s when it made its switch to nuclear power.
Central African Republic will reduce emissions by five per cent on business-as-usual levels by 2030, at a total cost of $3.69bn.

China has pledged for emissions to peak before 2030. It has said it will reduce its greenhouse gas emissions per unit of GDP by 60 to 65 per cent from 2005 level by 2030, while aiming to increase non-fossil fuel sources in primary energy consumption to about 20 per cent by the same date. The government has declared meeting the target will require $6.6tr of low carbon infrastructure investment to be mobilised through to 2030.
Colombia pledged to reduce its emissions by 20 per cent by 2030 compared to a business as usual scenario, but this could rise to 30 per cent will additional international finance.

Eritrea has promised to cut emissions by 80.6 per cent by 2030, compared to business-as-usual. Almost 40 per cent of this is unconditional. The country's pledge includes plans to boost its share of renewable energy in electricity generation to 70 per cent.
The EU has said it will reduce greenhouse gas emissions by 40 per cent compared with 1990 levels by 2030. Given expected economic growth in the region, this means the EU will likely have to double its rate of decarbonisation to meet the target. As a result, businesses can expect a step change in climate policy, regulation and investment over the coming years.
Ethiopia has pledged a 64 per cent reduction in greenhouse gas emissions by 2030 against a business-as-usual scenario. Given the country's anticipated economic growth, this equates to a three per cent cut against a 2010 baseline.
Equatorial Guinea aims to reduce emissions 20 per cent by 2030, relative to 2010 levels, as part of long-running efforts to achieve a 50 per cent reduction by 2050.

Ivory Coast committed to cutting emissions 28 per cent against a business-as-usual level, rising to 36 per cent if certain conditions are met.
Japan will reduce emissions by 26 per cent on 2013 levels by 2030. The country has been criticised in some quarters for not showing sufficient ambition with its new targets. But according to PwC, this means Japan will need to reduce its carbon emissions on average by 3.1 per cent each year, assuming economic growth of 1.4 per cent annually. This would require a major step change from the current 0.5 per cent decarbonisation rate.
Jordan said it would commit to cutting its greenhouse gas (GHG) emissions by 1.5 per cent from business-as-usual (BAU) levels by 2030. However, it added that the target could rise to 14 per cent conditional on international financial support.

Mali has pledged an average reduction of emissions of 27 per cent, with the biggest cuts hitting the energy and agriculture sector.
Marshall Islands has become the first island state to submit its INDC and pointedly opted for an absolute emissions reduction target and a 2025 target date, arguing such an approach is simpler and more robust than the 'below business-as-usual' goals endorsed by many developing nations. The country said it would cut emissions 32 per cent by 2025 and 45 per cent by 2030 against 2010 levels. It also said the new targets were part of its long term plan top become a net zero emission economy by 2050.
Mauritania will reduce its emissions by 22.3 per cent by 2030 compared to business-as-usual, however 88 per cent of this commitment is conditional on international support. Some 12 per cent of the pledge is unconditional.

Mexico has pledged to reduce greenhouse gas emissions 22 per cent compared with its 2030 business-as-usual emissions, which is roughly equivalent to a reduction of six per cent on 2005 levels. It has said it could raise its target to 36 per cent if there is a global agreement on a carbon price. Even the 22 per cent reduction would represent a step change in climate policies and investment. PwC analysis shows it would require Mexico to decarbonise at a rate of 4.8 per cent annually compared with a current trend whereby emissions intensity is slightly rising. The targets promise to cement Mexico's position as one of the world's most ambitious developing economies when it comes to climate action.
Moldova has promised to cut emission by between 64 and 67 per cent below 1990 levels by 2030. If international finance is provided, this could rise to 78 per cent.
