Carbon trading, co-pollutants, and environmental equity: Evidence from California’s cap-and-trade program (2011–2015)

Fig 2

Changes in annual average greenhouse gas emissions within California after implementation of the state’s cap-and-trade program.

Facility emissions 3 years after carbon trading began (2013–2015) are compared to those from the 2 years prior to the initiation of trading (2011–2012). Due to differences in accounting, comparable emission estimates are not available prior to 2011. n = number of facilities in each industry sector. t CO2e, metric tons CO2 equivalent.
