Adopting Local Climate Policies: What Have California Cities Done and Why?

Climate action at the local level represents an important and unique complement to global and national-level policies. This study provides one of the first systematic analyses of local climate actions in the State of California by comparing cities' adoption of alternative policies and statistical modeling of local choices of climate actions. The pattern of adopting different climate actions incrementally suggests that cities prefer certain actions than others. Coastal location, instead of the usual predictors of local mitigation actions, is found to affect cities' adaptation actions. Whether a city is more likely to keep its commitment to mitigate climate change depends on the nature of the commitment.
