"This bill and the executive order I am going to sign will put California on the path to meet the Paris agreement and beyond. It's not going to be easy, and it won't be immediate, but it must be done," Brown said.

De León called the legislation a "labor of love" and called climate change a real, dangerous and expensive threat. The bill aims to address both the scientific and economic setbacks of a warming globe, he said.

"Today California sends an unmistakable message to the nation and the world, regardless of who occupies the White House, California will always lead on climate change," he said at the presser. 

"Californians have made their voices heard loudly about the future they want for their state and the world. ... As Californians we are going to shape and drive that future."

The law comes as California is set to host the first Global Climate Summit in San Francisco this week, where big names in climate change and environmental science are anticipated to speak.
