Citizens' Climate Lobby is a national nonprofit headquartered on Coronado Island's Orange Avenue at 1330 Orange Avenue, Suite 309, where approximately 50 staff members coordinate the organization's 568 active chapters across the United States and more than 70 countries in the 92118 ZIP. The headquarters' position on Orange Avenue places the national office within the walkable village corridor that also houses the Coronado Historical Association and Museum and the island's civic and cultural institutions. CCL advocates for bipartisan climate legislation through a relational-lobbying model that trains volunteers to engage elected officials at local, state, and federal levels, and the organization's flagship policy proposal — a revenue-neutral carbon fee and dividend — has attracted bipartisan congressional sponsors since its introduction. The Coronado headquarters hosts staff managing chapter support, media relations, government affairs, and the annual international conference, and the organization's growth from a single chapter in 2007 to a network spanning all 50 states and 73 countries reflects a scalable grassroots infrastructure built from the 92118 base. Environmental awareness programming on Coronado Island connects CCL's mission to island residents who experience coastal-climate impacts firsthand — sea-level rise along the Silver Strand, sand erosion on Coronado Beach, and the storm-surge vulnerabilities that affect the Coronado Bridge approach and low-lying bayfront properties. The Coronado Public Library on Orange Avenue hosts community lectures and environmental-education programs that complement CCL's advocacy work by informing 92118 residents about climate science and policy options. The organization's national footprint operates from an island connected to mainland San Diego by the Coronado Bridge and the Coronado Ferry, with Hotel Del Coronado and the resort corridor providing conference and hospitality infrastructure for visiting staff and board members.
