We explore the air quality co-benefits of climate policy, and the mulitipollutant impacts of sustainabile infrastructure.
Making sustainable decisions means balancing multiple goals: a strong economy, a clean environment, an equitable society. Policies that focus on one goal, e.g., climate change policy, can lead to big wins or regrettable losses for our other goals if we are not careful in our policy assessment process.
Integrated assessment frameworks combining models of the economy and earth system have the power to make such synergies and trade-offs stark and concrete.
Saari Lab applies this powerful sustainability assessment tool to a key question: can air quality co-benefits justify climate policy?
There are increasing calls to consider the ancillary benefits for air pollution of climate policy – the benefits of reduced pollution are local, immediate, and affect human health. However, significant climate or energy policies can affect the economy and the multitude of air pollution sources in complex ways. Can we better understand these linkages to make more informed, robust decisions?
To explore this problem, we develop integrated assessment frameworks combining models of the economy and atmosphere with models of human health impacts.
