The social cost of carbon - or marginal damage caused by an additional ton of carbon dioxide emissions - has been estimated by a U.S. government working group at $21/tCO2 in 2010. That calculation, however, omits many of the biggest risks associated with climate change, and downplays the impact...

This paper proposes a ranking of the countries where forest carbon sequestration is the most cost-efficient among 166 countries for which data are available. Taking into account the main cost factors leads to a more nuanced ranking of the countries to be favoured for cost-efficient forest carbon...

Nitrogen management policies introduced in the past decades by some OECD countries have succeeded in reducing excess nitrogen use by farmers, but half of global mineral fertiliser use is still lost for crops. While about half of OECD countries have nutrient surpluses of between 25-50 kg N per...

This paper assesses quantitative estimates based on economic modelling studies of the economic and environmental benefits from different forms of international co-ordination on carbon pricing. Forms of international co-ordination include: harmonising carbon prices (e.g. through linking carbon...

This brief focuses on the role carbon pricing can play in the COVID-19 recovery and in reaching national and international climate goals, such as those in the Paris Agreement. It outlines the carbon pricing policy changes (Emissions Trading Schemes (ETS), fossil fuel support (FFS), carbon, fuel...

In this paper, we aim to examine how voluntary carbon markets can provide a valuable contribution to strengthening domestic and international climate policies. Voluntary markets are defined as small and unregulated segments of an established carbon market that are driven by voluntary offsetting...

The Paris Agreement invites signatory countries to formulate and communicate long-term low greenhouse gas emission development strategies (LT-LEDS). This report compares the experience of three developed countries that have communicated LT-LEDS within the framework of the United Nations...
