Environment

From California’s snow-capped mountains to its pristine coastline, from majestic forests to the painted landscapes of its deserts, California is home to some of the most unique ecosystems in the world. Senator Feinstein has dedicated her career to preserving our natural spaces, combatting climate change, and fighting for environmental justice.

Senator Feinstein led a successful bipartisan effort to significantly reduce greenhouse gas emissions from automobiles. Her bipartisan legislation, signed into law in 2007, the Ten-in-Ten Fuel Economy Act, raised fuel economy standards for America’s vehicles by at least 10 miles per gallon over 10 years, the largest increase in fuel efficiency in more than two decades, cutting greenhouse gas emissions from cars and light trucks in half.

A champion of preserving open space, she authored the historic California Desert Protection Act, which preserved more than seven million acres of California desert - the largest designation in the history of the continental United States. At her urging, President Obama used his authority under the Antiquities Act in 2016 to designate three new national monuments in the California desert, which protected almost 2 million additional acres.

She also helped secure over $250 million in federal funds to purchase and preserve the nearly 8,000 acre Headwaters Forest in order to save the last unprotected, intact, ancient redwood forest ecosystem on earth. She also authored successful legislation that saved nearly 300,000 acres of wilderness across Northern California, added 25,500 acres of land to the Redwood National Park in Del Norte County, and preserved over 21 miles of the Black Butte River in Mendocino County.

Senator Feinstein has also been a leader in preserving our waterways. By the 1990s, the San Francisco Bay had lost an estimated 85 percent of its historic wetlands to development, destruction, or alteration. She took action and personally negotiated the purchase of more than 16,000 acres of endangered wetlands from industrial developers along the San Francisco Bay and Napa River—the largest restoration of wetlands in California history.

And she also authored the Lake Tahoe Restoration Act, which launched a nearly $2 billion public-private partnership to restore Lake Tahoe and has protected over 17,000 acres of wildlife habit and restored more than 1,700 acres of Stream Environment Zones.
