The outlook for U.S. Environmental Protection Agency's (EPA) Clean Power Plan, a rule intended to limit greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants, is the subject of debate after two key Supreme Court events last week.
First, on Tuesday, the U.S. Supreme Court in a 5-4 decision issued a stay, delaying the execution of the plan, pending the outcome of legal challenges. The New York Times called the decision "unprecedented," because the Supreme Court had never before granted a request to halt a regulation before review by a federal appeals court. At a minimum, the ruling will allow states to skip the September deadline to submit compliance plans to the EPA.
A new twist on the fate of the Clean Power Plan came Saturday with the death of Supreme Court Justice Antonin Scalia--leaving the Supreme Court with eight justices split evenly between conservatives and liberals, and evenly split on the question of that week's stay. Whether the White House or the Senate will confirm a new justice before the November 2016 Presidential election remains unclear, although political cynicism about any nominee's chances has dominated commentary. President Obama announced plans to nominate a new justice, and Senate Republican leadership has indicated that it does not intend to confirm Obama's candidate.
The D.C. Circuit is set to begin hearing oral arguments challenging the Clean Power Plan in June. Any ruling may be reviewed by the Supreme Court.
ClimateWire suggests three potential scenarios. For Clean Power Plan opponents, the best turn of events would be appointment of a new conservative-leaning justice, which would be made possible if the Senate successfully blocks an Obama appointee and a Republican takes the White House. Those in favor of the plan would benefit from appointment of a new liberal-leaning justice or from the court's consideration of the plan before a new justice is confirmed.
Politics surrounding the nomination of the new justice are complicated, writes Tom Goldstein of the SCOTUS blog.
Study: More Aggressive Emissions Reductions Needed to Curb Air-Pollution-Related Deaths
A new study undertaken by the World Health Organization and presented last week at the annual meeting of the American Association for the Advancement of Science shows that 5.5 million die prematurely every year from air pollution. The authors--a team of U.S., Canadian, Chinese, and Indian scientists--said that most of the fatalities are in India and in China, where coal burning alone led to 366,000 deaths in 2013.
Researcher Qiao Ma from Tsinghua University in Beijing said coal burned for electricity was the largest polluter in China and that the country's new targets to reduce emissions, agreed at last year's Paris climate talks, are not sufficiently ambitious to end those deaths.
"Even in the most clean scenario in 2030," Ma said, China's growing and aging population will still suffer as many as 1.3 million deaths a year. "Our study highlights the urgent need for even more aggressive strategies to reduce emissions from coal and from other sectors."
Although China halted approval of new coal mines for three years at the end of 2015 and has issued stringent requirements similar to those recently proposed in the United States for new coal-fired power plants, these and other measures may not halt increases in mortality, reported Time.
"Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease," said Michael Brauer of the University of British Columbia. "Reducing air pollution is an incredibly efficient way to improve the health of a population."
Agreements Made to Expand Renewables, Reduce Emissions
Governors from 17 U.S. states signed an accord to diversify energy generation with clean energy sources, modernize their energy infrastructure and encourage clean transportation options. Home to about 40 percent of the country's population, states signing the Governors' Accord for a New Energy Future are California, Connecticut, Delaware, Hawaii, Iowa, Massachusetts, Michigan, Minnesota, New Hampshire, Nevada, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia and Washington.
"With this agreement, governors from both parties have joined together and committed themselves to a clean energy future," said California Gov. Jerry Brown. "Our goal is to clean up the air and protect our natural resources."
As part of the agreement, states will cooperate on planning and policies--pooling buying power to get cheaper clean-energy vehicles for state fleets and to build more energy-efficient regional electrical grids.
Also preparing for a cleaner-energy future is Fiji, which on Friday became the first country to formally approve the United Nations climate deal reached in Paris when its parliament ratified the agreement. Under its national climate action plan, the archipelago, which is vulnerable to flooding and strong tropical storms as a result of climate change, pledged to generate all its electricity from renewable sources by 2030 and to reduce its overall energy-sector emissions by 30 percent by 2030--if it receives climate finance from industrialized nations.
