Australia’s new climate legislation is a historic breakthrough and a substantial step in the right direction, but is still not stringent enough to help the world keep global warming to below 2 degrees C, according to a major analysis of the country’s climate actions, released here today by the Climate read more...

China is on track to meet – or even surpass – some of its Cancun climate pledges, yet its emissions will rise higher than expected, according to the latest Climate Action Tracker, released today at the Panama climate negotiations.The update includes an analysis of China’s 12th Five Year Plan, announced read more...

In this update the Climate Action Tracker provides some insights from the workshops and other material presented by countries at the on-going climate talks in Bonn. Despite the recent financial recession, global CO2 emissions in the energy sector grew by 10% overall over the past 5 years, from about 30 read more...

Bangkok climate talks have not changed the gap between emission reduction pledges and what is to needed to get the world on track for limiting global warming to 2 and 1.5°C above pre-industrial levels. No developed country attempted to increase their reduction target as it was requested in Cancun Agreements read more...

Globally business as usual emissions for 2020 of 57 GtCO2e are projected. To have a good chance at limiting global warming to 2°C or 1.5°C, 2020 emissions would need to be below 44 and 40 GtCO2e respectively. Hence the Copenhagen Climate Deal needs reductions of around 13-17 GtCO2e by 2020.
