Advocacy

2024 Proposition 4

In 2024, Kim Delfino and Earth Advocacy campaigned to get a $10 billion climate bond placed on the November ballot in California known as Proposition 4. The measure would fund projects to protect the water supply, increase wildfire resilience, and protect the coast from sea level rise. ⁴

Earth Advocacy led the Yes on 4 coalition-building for the 2024 ballot measure. ⁷ Earth Advocacy represented a coalition of hundreds of environmental groups, firefighters, labor groups, and agricultural organizations to back Proposition 4. ⁸

In promoting the ballot measure, Delfino said, “If we don’t do preventive care, then we’re going to get sick and we’re going to have to pay way more on the back end.“ ⁹

The measure was approved with 59 percent of voters backing it. ¹⁰

Energy Policy

Delfino has cited as among her proudest accomplishments advocating for the U.S. Bureau of Land Management’s Desert Renewable Energy Conservation Plan that set aside 388,000 acres of public land in the California desert for potential solar, wind, and geothermal energy development. She also cited helping to preserve 4.4 million acres of roadless forest lands in California, as well as supporting the effort to phase out lead ammunition in hunting in the state. ⁴

When the California Energy Commission considered advancing offshore wind energy in 2022, Earth Advocacy called for keeping current goals in place, arguing studies used as the basis for raising the goals did not adequately consider social and environmental concerns. ¹¹
