Bloomberg recently projected that "California [is] Poised to Overtake Germany as World’s No. 4 Economy" based on total GDP. However, looking at GDP per capita, California is currently the 6th highest state in the US.

When comparing GDP per capita with other countries and territories, California currently ranks #6 (assuming other US states are not included in the rankings - that is we rank only California and all countries and territories) according to the GDP numbers from the UN.

Many ambitious proposals have been put forward by California politicians, some to keep California competitive, others to accomplish other goals. As examples, California plans to sell only zero-emission vehicles by 2035 and construct high-speed rail from Anaheim to San Fransisco by 2033.
