The PM Group focusses on solving immediate and near-term environmental (health and ecosystems impacts from pollution), climate (non-CO2 greenhouse gases), and social (widening inequality gaps) problems in a cost-effective way, providing support to policymaking at local and regional scales.

The PM Group addresses sustainability challenges in the near and long term through an improved understanding of the multiple benefits of policies and their distribution across society. The group has a strong focus on the development of new approaches for multi-sectoral policy interventions to manage pollution across different media (air, water, and soil) at various scales to address near-term concerns and enable long-term transformations and their public support towards a sustainable future. In particular, the group endeavors to enhance the systems perspective approach to address and explore issues such as the interactions and environmental impacts of pollution; assessment of sources of non-CO2 greenhouse gases; mitigation opportunities; approaches to address nutrient and material cycling; options for more equitable solutions; and improved methods for estimating the health and economic benefits of policy interventions.

The need for rapid methane mitigation

Human-driven methane emissions account for nearly 45% of current net warming. The Global Methane Assessment 2030 baseline report, issued by the Climate and Clean Air Coalition and coauthored by IIASA researcher Lena Höglund-Isaksson, evaluates the progress of global reduction efforts. If the world is to keep global temperature rise below 1.5° and 2°C targets, swift action is needed.

Propane — a solution for more sustainable air conditioning

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy consumption and refrigerants with high warming potential. A new study finds that switching to propane as a refrigerant could lessen the global temperature increase from space cooling.
