Mitigation (of climate change) is a human intervention to reduce the sources or enhance the sinks of greenhouse gases. Mitigation also includes reduction of other factors that contribute directly or indirectly to climate change, such as short-lived climate forcers (methane, black carbon, sulfur dioxide, and similar).
In the Climate Mitigation group, we focus on understanding the trends and drivers of historical and future emissions of greenhouse gases and short-lived climate forcers.
Our work on historical trends and drivers closely integrates with the Global Carbon Budget and Global Methane Budget. We study recent trends in emissions and quantify the factors causing emission trends to change. We place emphasis on clear presentation of findings and communicate our findings to a broader audience through Rapid Response.
We also study scenarios for future emissions in both the short-term (next few years), medium-term (up to 2030) and the long-term (up to 2100 and beyond). Important activities include the relationship between temperature and cumulative emissions (carbon budgets), the role of short-lived climate forcers in mitigation, and the opportunities and challenges of climate mitigation within the context of social, political, and technological constraints.
Several of the group are involved in the upcoming IPCC Sixth Assessment Report. Jan Fuglestvedt is a vice-chair of Working Group 1 and Review Editor for the emission scenario chapter in the Special Report on 1.5C. Glen Peters is a lead author for the Working Group 3 chapter on emission scenarios.
