Blue Carbon Demonstration Projects in Coastal Zones

This vetoed bill would have allowed the California Coastal Commission to create special projects that measure how coastal plants store carbon, requiring some developers who harm these areas to help fund them.

What This Bill Does

  • Authorizes the commission to create blue carbon demonstration projects if funding is provided by law.
  • Requires measuring and quantifying how much carbon these projects can capture from the air or water.
  • Uses project data to inform state plans for natural lands, working lands, and climate resilience.
  • Allows the commission to require nonresidential developers who harm coastal habitats to build or pay for a demonstration project as compensation.

Who It Names or Affects

  • The California Coastal Commission
  • Applicants seeking permits for nonresidential projects in the coastal zone that impact specific marine areas
