In response to anthropogenic climate change, developed countries have committed themselves to raise 100 billion USD a year from 2020 onwards for addressing the needs of developing countries. In this paper, we investigate the economic and CO2 emission impacts of four alternative options for...

Intensity standards have gained substantial momentum as a regulatory instrument in US climate policy. Based on numerical simulations with a large-scale computable general equilibrium model we show that intensity standards may rather increase than decrease counterproductive carbon leakage....

Despite recent achievements towards a global climate agreement, climate action to reduce greenhouse gas emissions remains quite heterogeneous across countries. Energy-intensive and trade-exposed (EITE) industries in industrialized countries are particularly concerned on stringent domestic...
