Greenhouse gas (GHG) emissions baselines are reference emissions levels. This paper focuses on projected forward-looking baselines that can be used both to inform national climate policy and to set goals that are defined relative to a business-as-usual (BaU) scenario. As some developing...

The main argument in favor of markets in environmental contexts is the same as in other contexts: their ability to promote efficient allocations and production. But environmental problems bring their own challenges: their underlying bio-physical processes - and the technologies to monitor them -...

The Bali Action Plan (BAP) indicated the importance of “measurable, reportable and verifiable” (MRV) greenhouse gas (GHG) mitigation actions and commitments, as well as support for GHG mitigation actions, in the post-2012 climate framework. Negotiations underway for this framework have...

Using new surveys on more than 40 000 respondents in twenty countries that account for 72% of global CO2 emissions, we study the understanding of and attitudes toward climate change and climate policies. We show that, across countries, support for climate policies hinges on three key factors:...

COP27 will return to Africa for the first time since 2016 to follow up on promises made in Glasgow in 2021 to limit global temperatures to well below 2°C by the end of the century as committed under the Paris Agreement. Nationally Determined Contributions (NDCs) enable each country to pursue a...

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...

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...

Sectoral approaches are proposed as a means to broaden the global scope of greenhouse gas (GHG) mitigation to developing countries. Market mechanisms are put forward in that context to create incentives for mitigation in developing countries beyond the existing Clean Development Mechanism (CDM),...

China, Japan and Korea have deployed a multiplicity of co-operation efforts at different levels of government to promote air quality and curb transboundary pollution. This paper identifies the existing arrangements for air quality co-operation in North East Asia and provides guidance to advance...
