California’s latest auction of greenhouse gas permits saw low demand, hurting state revenue, according to figures released yesterday. The Feb. 22 auction sold just 16.5 percent of the 75 million allowances put up for auction by California; its trading partner, Quebec; and utilities that receive allowances to sell.

California’s cap-and-trade program limped through another weak auction of pollution permits last month, according to results provided by state regulators Wednesday. Demand for the permits, which are required to release greenhouse gas emissions into the atmosphere, has fluctuated over the last year amid questions about the program’s long-term viability.

California’s carbon market generated little interest from buyers at last month’s permit auction, results released on Wednesday showed, raising concern about the program’s ability to deliver funding for projects like the state’s bullet train. California along with its carbon market partner Quebec sold 18 percent of the over 65 million permits it offered up to businesses at the sale, which was held on February 22.

Any changes or repeal of President Obama’s signature Clean Power Plan will depend heavily on the outcome of a legal challenge by a federal appeals court in Washington D.C. If the court rules that the EPA does not have the power to regulate, Pruitt and the Trump administration could try and simply rip the plan up. But if the rule is found to be legal, then Pruitt will have to find a way to either change some provisions or begin the long and laborious process of writing an entirely new plan with much less ambitious targets.

Repealing the Clean Power Plan would have significant impacts on the United States’ economy and the health of its citizens, according to new analysis from Energy Innovation, a clean energy think tank.

In a new paper, America’s Power Plan laid out a four-step process for utilities and regulators to choose their goals (clean energy and carbon reduction, fair and low prices for all, and utility-specific grid values) and then compare the cost of making smart grid upgrades versus not making them in order to achieve those goals.

As environmental standard-bearer and green technology pioneer, no other state rivals California. For decades, California has been at the forefront of U.S. environmental policies. Now, with the Trump administration poised to attack environmental and climate regulations, California is ready to play a key role in resisting Washington’s hard right turn.

Kevin de León has promised to lead the resistance to President Trump. A new bill could make good on that promise. The California Senate leader has introduced legislation that would require the Golden State to get 100 percent of its electricity from climate-friendly energy sources by 2045.

According to a model created by Energy Innovation, a San Francisco research firm, a freeze of fuel efficiency standards at the current mpg level will cost consumers $64 billion through 2030, and $282 billion by 2040. By 2050, all that extra fuel would add $475 billion to household budgets, or about $1,500 for every American, it says.
