According to the OECD report ‘Climate Change Mitigation - Policies and Progress‘, tackling climate change is a difficult political challenge requiring a high level of trust and cooperation between countries. Global greenhouse gas (GHG) emissions need to be 40 70 % below 2010 levels by 2050 and near zero or negative by 2100 to hold the rise in global average temperature to below 2 ºC.
And although most of the countries studied are making some progress towards meeting their mitigation targets and goals; many are on a trajectory that is likely to fall short in the absence of a significant acceleration in annual emission reduction rates, says report.
The authors of the report perceive that if current trends continue, there is a high probability of significantly greater temperature rises, increasing the risk of severe and irreversible impacts on ecosystems, significant disruptions to agricultural systems and impacts on human health in this century and beyond.
This report presents trends and progress on climate change mitigation policies in the 34 OECD member countries, the European Union and 10 partner economies (Brazil, the People’s Republic of China, Colombia, Costa Rica, Indonesia, India, Latvia, Lithuania, the Russian Federation and South Africa).
It is intended to increase transparency and improve understanding of mitigation goals and the extent to which carbon pricing instruments and other policies to address GHG emissions have been implemented across different economic sectors.
