Acting on climate change means both reducing greenhouse reducing GHG emissions from sources gas (GHG) emissions from local sources in the unincorporated within the unincorporated area, and by County and helping the community to adapt to climate change and identifying threats and strategies for adapting to future environmental conditions caused by improve its resilience over the long term. climate change. The scientific consensus is that it is “extremely likely” that global climate change is caused by GHG emissions associated with human activities, and that significant reductions in human-caused GHG emissions are needed by the mid-21st century to prevent the most the catastrophic effects of climate change. To this end, in 2006, the California Global Warmings Solutions Act (Assembly Bill [AB] 32) established the State’s first target to reduce GHG emissions, which As directed by AB 32 and SB 32, the State established a goal of lowering emissions to 1990 levels by 2020. aims to reduce annual GHG emissions to: California has been making steady progress and is expected to . 1990 levels by 2020, . achieve the 2020 target; however, ongoing reductions in GHG 40 percent below 1990 levels by 2030. emissions are needed as noted above. The State’s longer-term goal is to reduce emissions down to 80 percent below 1990 levels by 2050. In 2016, Governor Brown signed Senate Bill (SB) 32 was signed into law, which established a new mid-term target of 40 percent below 1990 levels by 2030. This target aligns with those of leading international governments such as the 29-nation European Union which adopted the same target in October 2014. The new 2030 target places California on a trajectory towards meeting its longer-term goal, which is to bring emissions down to 80 percent below 1990 levels by 2050. Over the last decade, the County of Napa (County) has taken several steps to begin addressing climate change and achieving reductions in GHG emissions, both in the County’s operations
