The MIT Joint Program on the Science and Policy of Global Change launches its Tool for Air Pollution Scenarios (TAPS), which can be used to estimate the likely air-quality and health outcomes of a wide range of climate and air-quality policies at the regional, sectoral and fuel-based level.
The related study study’s initial application of TAPS shows that with current air-quality policies and near-term Paris climate pledges alone, short-term pollution reductions give way to long-term increases–given the expected growth of emissions-intensive industrial and agricultural processes in developing regions. More ambitious climate and air-quality policies could be complementary, each reducing different pollutants substantially to give tremendous near- and long-term health benefits worldwide.
TAPS projects air quality and health outcomes based on three integrated components: a recent global inventory of detailed emissions resulting from human activities (e.g. fossil fuel combustion, land-use change, industrial processes); multiple scenarios of emissions-generating human activities between now and the year 2100, produced by the MIT Economic Projection and Policy Analysis (EPPA) model; and emissions intensity (emissions per unit of activity) scenarios based on recent data from the Greenhouse Gas – Air Pollution Interactions and Synergies (GAINS) model.
The tool can inform decision-makers about a wide range of climate and air-quality policies. Policy scenarios can be applied to specific regions, sectors or fuels to investigate policy combinations at a more granular level, or to target short-term actions with high-impact benefits.
