This has been a big week for advocates who fight climate change. Business leaders, mayors, governors and activists from around the world rallied in San Francisco at the Global Climate Action Summit to advance their agenda in the face of a defiant White House.

California Gov. Jerry Brown issued an order Monday announcing the goal to eliminate carbon emissions in the state within 27 years. He also just signed a bill into law, making the state’s electricity completely emissions-free by 2045. Brown signed as the White House reportedly enacted another policy to stymie such efforts, this time by relaxing methane emission regulations.

For advocates pressuring big pension funds, companies and investment firms to deploy their money with the environment in mind, a good return looks to be the best motivator.
