NewClimate Institute, IIASA and PBL have estimated the impact of good practice policies on greenhouse gas emissions. The goals of this assessment were to identify practical ways to enhance emission reduction, and to illustrate how this could help to limit global temperature increase to 2°C. This report identifies good practice policies and analyses the impact if they are implemented by China, United States, India, Brazil, the Russian Federation and Japan, and on a global level, across a number of sectors.
Good practice policies could contribute significantly to greenhouse gas reductions necessary to achieve the 2°C target
- The potential of replicating good practice policies is large; they could contribute significantly to the reduction in GHG emissions necessary for staying on track to achieve the 2°C target.
- Worldwide implementation of good practice policies in nine selected policy areas is projected to decrease emissions by 2020 and 2030 to levels close to the range, necessary for limiting global temperature increases to 2°C
- Good practice policies can halt the increase in emissions, in most regions, before 2030.
- Replicating good practice policies in the electricity, transport and buildings sector can decrease the energy and carbon intensity in these sectors to the levels that are required for staying below 2°C increase.
