Former executive director and chairman of the Sierra Club, now principal advisor at Inside Straight Strategies and As You Sow Board member
“Through my decades at the Sierra Club and in the environmental movement, I’ve come to understand that corporations can — and must — play a critical role in addressing our climate crisis. It’s something Michael Bloomberg and I dive into in our book, Climate of Hope: How Cities, Businesses, and Citizens Can Save the Planet, and it’s why I support As You Sow. As You Sow punches way above its weight, driving sustainable, ethical shifts at big corporations, and racking up major victories that benefit everyone, including the company.”
Carl has served on the Boards of the California League of Conservation Voters, Public Voice, National Clean Air Coalition, California Common Cause, Public Interest Economics Inc, and Zero Population Growth, but his longest-standing board service is to As You Sow — since 2011, a testament to As You Sow’s integrity and effectiveness.
