States work on their own green policies

— Even WASHINGTON though talk of a “Green New Deal” is getting louder in Congress, the odds of major federal climate legislatio­n passing in the next two years remain extremely low.

It’s a different story at the state level, however: The midterm elections in the fall brought in a new wave of governors who are now setting climate goals for their states and laying out more ambitious plans to cut emissions and expand low-carbon energy.

In the past month, newly elected Democratic governors in Michigan, Illinois and New Mexico have joined the U.S. Climate Alliance, a group of 19 states and Puerto Rico that has vowed to uphold the Paris climate agreement despite President Donald Trump’s disavowal of the accord. With the new additions, the alliance now covers one-third of America’s greenhouse gas emissions and nearly half its population.

States can only do so much to tackle climate change by themselves. But they can serve as laboratori­es of sorts, testing which climate policies work well and which ones are ineffectiv­e or too costly.

Here are some of the biggest steps states have taken recently on climate policy.

More wind and solar power

For years, the go-to climate move for states has been to require utilities to use more renewable electricit­y, a task made easier by the rapid decline in costs for wind and solar power. Governors are now poised to accelerate those policies.

In Maine, the new governor, Janet Mills, a Democrat, has vowed to restore incentives for rooftop solar and to boost wind power locally — moves that had been stymied by her Republican predecesso­r.

In New Mexico, another Democrat, Gov. Michelle Lujan Grisham, is backing a bill requiring electric utilities to get 50 percent of their power from renewable sources by 2030, keeping pace with neighbors like Colorado and Nevada.

The most striking developmen­t, though, has been the array of governors who are now floating plans for their states to get 100 percent of their electricit­y from zero-carbon sources. Legislator­s in California and Hawaii have already set deadlines for utilities to meet this target by 2045. In recent months, the governors of Colorado, Illinois, New Jersey and New York have pledged to pursue similar goals.

These states are all venturing into uncharted territory, and there’s no guarantee they will succeed. As states rely on ever-larger amounts of wind and solar power, it becomes more challengin­g to juggle these intermitte­nt sources. Getting all the way to 100 percent zero-carbon electricit­y, experts say, could require extensive new nationwide transmissi­on lines, novel energy storage techniques or help from untested technologi­es like advanced nuclear power.

Cutting pollution from cars

Electricit­y is responsibl­e for about one-third of America’s carbon dioxide emissions. To go further, states will also have to clean up the cars and trucks on their roads, which account for another third.

In December, nine Eastern states and the District of Columbia announced they would work together to put a price on emissions from transporta­tion fuels and invest the revenue in lower-carbon solutions, potentiall­y including mass transit, electric buses or new charging stations to make it easier for people to own plug-in vehicles.

Some of the states involved, like Pennsylvan­ia and Maryland, are in danger of missing their self-imposed climate goals unless they can halt the stubborn rise in driving emissions.

While the finer details of the policy will be hashed out this year, the states are modeling their efforts after the Regional Greenhouse Gas Initiative, a cap-andtrade system in the Northeast that auctions a steadily dwindling supply of carbon pollution permits to power plants and uses the revenue to invest in efficiency and clean energy programs.

“Transporta­tion is going to be even more complex than electricit­y — there are so many moving parts,” said Vicki Arroyo, the executive director of the Georgetown Climate Center, which has been working closely with the states on the initiative.

More carbon pricing

In November, voters in Washington state rejected a ballot initiative to impose a statewide tax on carbon emissions — a sign that putting a price on carbon, a favorite solution of many economists, remains a tough sell politicall­y.

But the idea is far from dead: In neighborin­g Oregon, the Legislatur­e is now considerin­g a statewide cap-and-trade system that would put a price on emissions from a wide range of polluters, including manufactur­ers, paper mills, refineries and utilities. The bill faces a tough battle, but if it were to pass, Oregon could link up with California and Quebec to create a carbon trading system.
