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.

Input to European Union Climate Policies

Since more than 10 years, IIASA's GAINS model provides scientific input to the development of the climate policy proposals of the European Commission, dealing with (a) emission projections, mitigation potentials and costs for non-CO2 greenhouse gases, and (b) interactions and synergies between climate and air pollution strategies.

Drowning in waste: pollution hotspots in aquatic environments

A new IIASA study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

Transforming waste into a valuable resource

As the world marks the International Day of Zero Waste, Adriana Gómez-Sanabria highlights that the path to zero waste will require a shift in society’s current consumption and production patterns. Originally conceived to shield humanity and the environment from the fallout of our actions, waste management systems must now evolve into engines of sustainability.
