While the global recession is cutting output, and thus reducing carbon output, their research suggests that carbon pricing policies are responsible for 40% of the fall in carbon output. The recession accounts for 30% of the fall.
New Carbon Finance chalks the decrease up to a shift in energy sources on the continent. Total electricity usage rose .3%, while emission from power sources dropped 2%. An increase in the use of natural gas, as well as slight lifts in wind, hydroelectric and nuclear power use, all contributed to lowering carbon output.
