Tackling the problem of global climate change requires a high level of international cooperation. Many countries have pledged targets or actions to reduce greenhouse gas emissions in the Appendices to the Copenhagen Accord. This analysis examines the costs and effectiveness of these pledges,...

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...

The importance of cities in climate policy stems from the simple reality that they house the majority of the world’s population, two-thirds of world energy use and over 70% of global energy use emissions. At the international level, global carbon markets have become an important new source of...

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...

A wide range of organisations operate at the interface between the demand for (e.g. water agencies or service providers) and the supply of finance (e.g. financing institutions and financiers at large) with the aim of bridging the substantial financing gap for water-related investments. These...

This paper analyses the long-term effects of the COVID-19 pandemic and associated government responses on the environment. It uses large-scale modelling to investigate the impact of sectoral and regional shocks to the economy until 2040. These detailed economic impacts are linked to a range of...

This paper explores data and methods to assess the alignment or misalignment with climate mitigation objectives of investments in the construction and refurbishment of residential and non-residential buildings. It takes the United Kingdom (UK) as a case study, where such investments reached GBP...

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...
