High-tech ferry backdrop for 16 California clean energy laws

California Gov. Jerry Brown used a high-tech battery-operated San Francisco Bay sightseeing ferry as the backdrop for approving 16 new laws Thursday aimed at easing global warming.

The bills he signed into law aim to increase the number of zero-emission vehicles and charging stations and reduce the number of heavily polluting cars and trucks.

The effort is key to California’s goal of reducing greenhouse gas emissions because pollution from vehicles has risen even as emissions from other sources drop.
