Australia has committed to achieving net zero greenhouse gas emissions by 2050 and more recently outlined a more ambitious intermediate target for emission reductions by 2030. However, achieving these targets will be challenging given a historical reliance on coal generation and the presence of...

The EU’s ambitious Green Deal aims at achieving net zero emissions by 2050. The EU is starting from a relatively good position. It has successfully reduced greenhouse gas emissions over the past decade. But further efforts are needed to reach the net zero target. These include an extension of...

Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

Switzerland has low greenhouse gas emissions per capita as compared to other countries, which reflects the strong reliance on energy sources emitting few greenhouse gas emissions, especially in electricity generation, and little heavy industry. Greenhouse gas emissions have remained almost the...

Considering the costs and risks of inaction, ambitious action to reduce greenhouse gas emissions is economically rational. However, success in abating world emissions will ultimately require a least-cost set of policy instruments that is applied as widely as possible across all emission sources...
