The Climate Action Tracker reveals major differences between the ambition levels of countries when it comes to reducing greenhouse gas emissions.
In the lead are the Maldives, who have proposed to become climate-neutral by 2020.
Also at the high end of the scale are Bhutan, which proposes to stay carbon neutral and Costa Rica, which proposes to become carbon neutral by 2021 if international support is provided. They are followed by Norway, Papua New Guinea and South Korea, all of whom are proposing to reduce their emissions significantly.
In the 'medium' range are developing countries such as Brazil, Chile, India, Indonesia, Mexico and South Africa. Many of them propose to reduce the growth of their emissions by the 2020’s.
The EU is a special case. We rate its unconditional commitment of 20% reduction 'inadequate'. However, adoption of a 30% reduction target would move the EU into the 'medium' range and very close to 'sufficient'.
Between the middle and the bottom of the scale is the United States, whose target is 'inadequate'. At the very bottom end of the scale are countries that have yet to propose substantial action beyond 'business as usual', including Russia and Moldova.
Japan revised its 2020 pledge in November 2013 and now aims to reduce emissions by 3.8% below fiscal year 2005 levels by 2020, in comparison to reducing emissions by 25% below 1990. This change moved it from a relatively high rating to the 'inadequate' category.
