The State of California has been steadfast in battling climate change and has passed several pieces of legislation including the Global Warming Solutions Act of 2006 which established a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. California is at the forefront of working towards 100-percent renewable energy by 2045.
