California is a global leader in climate policy, and its
goal of 100% clean energy by 2045 is now law in the 5th largest economy after
China, the US, Japan and Germany.
While the state has had a cap and trade program in place
since 2013, it has been the simplicity and directness of a mandate that has
most certainly reduced its carbon emissions as the percentage of renewable
energy has risen from almost nothing eight years ago to 40% in 2018, more
than beating its 2020 target of 33% by two years.
