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.

EEA finds only mixed progress for Europe’s transport sector in meeting environment, climate goals; GHG emissions up 25% since 1990

Green Car Congress

Oil consumption by the transport sector will need to fall by more than two-thirds to meet the objective of reducing consumption by 70% by 2050 compared with 2008 levels. The share of renewable energy in transport in the EU rose from 6.7% in 2015 to 7.1% in 2016, lower than the 10% target set for 2020.
