Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.

ICCT study finds hydrotreating an inexpensive approach to remove naphthalenes from petroleum jet fuel for contrail abatement

Green Car Congress

Recent studies have indicated that contrails likely contribute to global radiative forcing at a level that is roughly equivalent to that of the CO 2 emissions from the entire aviation sector, which is estimated to be about 2% of total global CO 2 emissions. soot) present in the engine exhaust.
