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.

New IPCC Report: we can halve emissions by 2030

Between 2010 and 2019, average annual global greenhouse gas emissions were at their highest levels in human history, but the rate of growth has slowed. Without immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach. However, there is increasing evidence of the success of climate action, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report.

Tackling solid waste management in Kenya

Options Winter 2021: Lack of proper waste management poses a threat to both the environment and human health. To alleviate the problem, IIASA researchers analyzed how waste management interventions such as turning waste into biofuel and a ban on open burning would impact air pollution, COemissions, and health in Kisumu county, Kenya.
