Caring for Our Common Home

The Driving Forces Behind Our Movement

Statewide Solutions to the Global Climate Crisis

California must lead the movement to address the climate emergency. That means creating a roadmap — inclusive of environmental justice and good paying union jobs — to transition from dirty fossil fuels to locally-produced renewable energy. As the world’s fifth largest economy, California has the profile and the power to demonstrate meaningful reforms that set an example for other states and nations to follow. Help us create the political will to make this vision a reality at

Our Focus

The mandate and the timeline are clear as day. We have a global climate emergency, and the only solution to the greatest existential crisis ever faced by our human family is to go carbon neutral — right now, while we can still give future generations a fighting chance. Everyone must play a part — governments, industry, organizations, and individuals. We must think beyond ourselves and beyond tomorrow. Step one is fulfilling California’s promise as a climate leader. That’s why we need your help in inspiring governor Gavin Newsom and all our state’s elected leaders to unify behind an official climate emergency declaration.

2020 showed us what it looks like when we’re unprepared for an emergency situation. It demonstrated the need for a clarity of purpose, a spirit of cooperation, and plans to address the worst case scenarios. In 2021, we have an unprecedented opportunity to organize for a carbon-neutral California. Now is the time to curb our statewide dependence on fossil fuels, transition our workforce into the new, green economy, and set a high bar that demonstrates true commitment to climate action. Declaring a climate emergency is just the beginning. You can help us ensure our leaders take the right steps, in the right order. Join the movement at

A Romero Institute Initiative

For over 30 years the Romero Institute has combined public education, grassroots organizing, and high-impact legal services to create social change. Our name honors Archbishop Óscar Romero of El Salvador. Like him, we seek justice for the most marginalized and voiceless among us. We take action where our objectives have the potential for large-scale impact, and we embrace new ways of thinking that promote a consciousness of unity and cooperation.

In 2016, inspired by Pope Francis’ call to “care for our common home,” and by the climate crisis our planet faces, the Romero Institute launched Greenpower (now becoming Let's Green CA). Our movement has expanded across California, where we're hard at work putting together an alliance of organizations and jurisdictions to create a carbon-free Central Coast.
