A Multi-Pollutant Strategy

An integrated approach could prove more effective for controlling emissions.

Fortnightly Magazine - January 2009

to supplement regional reductions from trading.

The Road Ahead

These lessons might prove useful to stakeholders in working with EPA, States and Congress towards a widely acceptable multi-pollutant strategy. Past proposals were not as far apart as one would expect in core program elements, including significant emission reductions and utilization of some degree of emissions trading. This suggests that the time has come to recognize these commonalities and bridge the gaps on the remaining issues. There remains enormous promise in the benefits of a meaningful market-based multi-pollutant control strategy.

This benefits calculation arises from EPA’s primary benefits methodology (value of a statistical life or VSL approach). An alternative, age-adjusted approach (value of a statistical life year or VSLY approach) results in monetized benefits of $46.7 billion in 2010.
