Synergies of Reducing Greenhouse Gases and Nitrogen Pollution in Europe

Climate change and environmental degradation caused by greenhouse gases (GHGs) and reactive nitrogen (Nr) emissions threaten our future. Two urgent, interconnected goals in Europe and globally are reducing GHG emissions to address climate change and curbing Nr pollutants for food security and ecosystem protection. However, most current studies identify technologies and pathways for ""GHG reduction"" or ""Nr mitigation"" separately, and the policies focus on mitigating either GHGs or Nr in isolation, Such narrow approaches face high costs and social barriers, conflicting with the multidimensional needs of integrated environmental policies and cost-effective solutions. Coordinated efforts to simultaneously address GHGs and Nr (GHG-Nr) could promote synergies and cost savings through shared implementation costs while driving effective, efficient reductions. To enable synergistic and cost-effective mitigation policies, SynCAN will: (1) analyze interactions and drivers of GHG-Nr emissions in Europe
