California’s Cap and Trade

Spotlight Issue: Bipartisan, International Climate Action: California’s Cap and Trade

In July 2017, California lawmakers voted to extend California’s Cap and Trade system until 2030, with support from both Democrat and Republican lawmakers. This proved a landmark moment for climate change policy in the US, as so far Republican lawmakers have generally been opposed to legislation on carbon reductions – particularly cap and trade.

California’s cap and trade program is a particularly important step towards the US’s emissions reduction goals under the Paris Agreement, as it aims to reduce carbon emissions by 180 million metric tons by 2030, and is linked to cap and trade programs in Alberta and Quebec, promoting international cooperation on climate change and demonstrating that a market-based approach to reducing greenhouse gas emissions can be implemented on a large scale. The framework that California has created for its cap and trade program could be expanded to include other states or provinces across the US and Canada.

The response from politicians across the country has also been extremely polarized – many Republicans call for the removal of the eight Republicans who voted to approve the measure, but many others call for more Republicans in other states to do the same. Depending on the future success of the California Republicans who supported the bill, it could mark a turning point in the partisan division over climate change in the US.

Status: Right Direction

The extension of California’s cap and trade program represents a bold move forward in climate action. The fact that it was passed with both Republican and Democratic support demonstrates that it is possible to focus on climate change mitigation policy despite partisan differences, a necessary political change in the American political landscape.
