88 Avoid bad corporations Did you know that just 100 companies have been the source of more than 70 percent of global industrial greenhouse gas emissions since 1988? Fifty of them, unsurprisingly, are fossil fuel companies. Another list compiled by Forbes ranked 890 corporations based on seven priorities to see who was doing right by America—take special note of who ended up at the bottom of the list.

89 Elect candidates with good climate plans Sixty-nine percent of voters believe the U.S. should take “aggressive” action to reduce greenhouse gas emissions. But how, exactly?

Many national parks are directly facing the realities of climate change.

93 Endorse the Paris agreement While the current administration is pulling the U.S. out of the global pact to reduce emissions, We Are Still In—a group of thousands of leaders from America’s cities, states, tribes, businesses, colleges, and universities that’s been embraced by the United Nations—is continuing to support climate action that meets the commitment of the agreement. Your organization can join them.

97 Fund renewable energy initiatives Put your money where the emissions aren’t. The Solar Foundation, Grid Alternatives, and RE-volv are three good places to start.

98 Support federal transportation reform For decades, the U.S. has funneled billions to new roads and highways, no questions asked.

Transportation for America is a great resource for tracking proposed legislation.

99 Run for office Organizations like Run for Something, Victory Institute, SheShouldRun, VoteRunLead, and Higher Heights help elect people who have not traditionally held public office. These groups host in-person events, online trainings, and supportive communities for offices open at local, state, and national levels.
