California’s groundbreaking cap-and-trade program designed to rein in carbon emissions will grow into the next decade and include partners in Toronto and parts of the Brazilian Amazon under a proposal released Tuesday by the state Air Resources Board detailing how the agency plans to hit Gov. Jerry Brown’s greenhouse gas reduction targets.

The board released the proposal at a make-or-break moment for the state’s cap-and-trade program.

A state appeals court is expected to rule sometime this summer on a lawsuit from the California Chamber of Commerce that challenges parts of the program. Some lawmakers also believe they have to renew the program’s authority for it to continue.
