Despite their limitations, GWPs are widely used for comparison among long-lived gases, forming the basis for worldwide political agreements on climate and carbon trading. Because the latter was a $126 billion/year market in 2008, even small differences in GWPs can have large economic consequences. Drew Shindell. Drew Shindell.

However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. The most immediate, effective and low-cost way to reduce soot emissions is to put particle traps on vehicles, diesel trucks, buses, and construction equipment.
