CA SB1036

Makes it unlawful for a person to verify, certify, issue, maintain on a registry, market, or sell a voluntary carbon offset if they know or should know that the greenhouse gas reductions or removal enhancements are unlikely to be quantifiable, real, and additional.

Prohibits marketing or selling a voluntary carbon offset without explicitly stating it is not physically equivalent to carbon dioxide emissions, unless technical evidence shows the offset's reductions or enhancements face no more than negligible reversal risk over at least 1,000 years.

Prohibits marketing or selling a voluntary carbon offset with non-carbon dioxide greenhouse gases without explicitly stating it is not physically equivalent to carbon dioxide emissions if those gases have an atmospheric lifetime of less than 1,000 years.

Creates Chapter 7 in Part 3 of Division 7 of the Business and Professions Code to regulate voluntary carbon offsets in California.
