He also found that soot emissions kill more than 1.5 Greenhouse gases, in contrast, typically persist in the atmosphere for decades—some up to a century or more—creating a considerable time lag between when emissions are cut and when the results become apparent. Particle traps filter out soot particles from exhaust fumes.
