In 1868 the world’s first traffic light was installed outside the Houses of Parliament. The gaslit signal controlled the flow of London carriages—at least for a few weeks.

The California environmental agency that probed Volkswagen AG's (VOWG_p.DE) diesel vehicles for violating pollution-control rules is now scrutinizing whether some gasoline-powered vehicles are emit

A wildfire that has forced thousands of Californians to flee their homes exploded in size on Wednesday, threatening a picturesque gold rush town outside Yosemite National Park as dozens of blazes s

California's legislature passed a package of bills that extends the state's signature plan to address climate change by a decade, sending Governor Jerry Brown a cap-and-trade plan that uses market

Not that long ago, the world wondered whether clean energy could survive without lavish government support. Now the question is how far it can spread.

New York State's attorney general and 12 other top state law enforcement officials said on Friday they would mount a vigorous court challenge to any effort to roll back vehicle emission rules by th

An ecologically and economically disruptive harmful algal bloom (HAB) affected much of the northeast Pacific margin in 2015, during a prolonged oceanic warm anomaly. Caused by diatoms of the genus Pseudo-nitzschia, this HAB produced the highest particulate concentrations of the biotoxin domoic acid (DA) ever recorded in Monterey Bay, California. Bloom inception followed strong upwelling during the spring transition, which introduced nutrients and eliminated the warm anomaly locally.

Taxes on sugar-sweetened beverages (SSBs) meant to improve health and raise revenue are being adopted, yet evaluation is scarce. This study examines the association of the first penny per ounce SSB excise tax in the United States, in Berkeley, California, with beverage prices, sales, store revenue/consumer spending, and usual beverage intake.

Projections of the economic consequences of climate change are valuable for policy making but generally rely on integrated assessments that cannot account for highly localized climate effects. Most agricultural climate impact studies focus on local effects or partial productivity measures insufficient to capture national economic outcomes. Here, we directly link climate variables in specific US regions to total factor productivity (TFP).

A combination of the Low Carbon Fuel Standard (LCFS) and California’s Cap-and-Trade Program can reduce the state’s greenhouse gas emissions and reduce dependence on oil more economically and effectively, relative to Cap-and-Trade alone.
