Climate change is a defining challenge of our times. This column introduces a special issue of the Journal of Economic Geography on climate change, which provides foundations for well-informed policymaking by addressing two main themes of the economic geography of climate change. First, climate change yields heterogeneous effects across space. Second, a crucial aspect of human adaptation to climate change is geographic mobility. As a consequence, limitations to mobility will worsen the socioeconomic costs of climate change. Other margins of adjustment covered in the issue include fertility, specialisation, and trade.

The target for global warming agreed on in the 2015 Paris Agreement implies that effective policies must be implemented to reduce emissions for the whole planet as soon as possible and reach net zero in the second half of the 21st century. The contributions in a new CEPR eBook aim to identity, for each of the featured nations, which climate change policies will have the fastest and/or largest cumulative impact, and which are the most technically, financially, or politically feasible. Although the low-hanging fruit in climate policy vary across countries, this does not mean that one country cannot learn from the debates taking place in another.

The overwhelming majority of publicly listed companies around the world still do not disclose their carbon emissions, and even fewer privately held companies do so. This column introduces a new CEPR Policy Insight in which the authors argue that mandatory carbon disclosures can make an elementary but essential contribution to the global drive towards a net zero economy, and recommend a mandate for the governments represented at COP26 to adopt.
