Does California’s Low Carbon Fuel Standards reduce carbon dioxide emissions?
Samir Huseynov e outros, 2018 · PLoS ONE
California's Low Carbon Fuel Standard reduced transportation CO2 emissions by an average of 19.7 million metric tons per year, representing a 9.85% reduction.

We also calculate the average treatment effect for California by averaging the treatment effects for all the post-intervention periods (-19.7 MMT CO2 or a 9.85% reduction).
Contexto
What changed: California launched the Low Carbon Fuel Standard to decrease the carbon intensity of on-road motor fuels across their entire life cycle. Comparison: California is compared to a synthetic control constructed from 42 US states that did not implement low-carbon fuel standards. Limits: The evaluation captures only the first phase of the policy (2010–2014), when mandated reduction targets were relatively low compared to later stages.
