The Environmental Protection Agency (EPA) intends to issue a scientific finding that greenhouse gases from aircraft pose a risk to human health, paving the way for regulating emissions from the U.S. aviation industry.
Touching off what is likely to be a long and contentious regulatory process, the EPA on Wednesday said it is “proposing to find under the Clean Air Act that greenhouse gas (GHG) emissions from commercial aircraft contribute to the pollution that causes climate change endangering the health and welfare of Americans.”
At the same time, the agency released information about the international process underway by the International Civil Aviation Organization (ICAO) for developing carbon dioxide (CO2) standards for aircraft and EPA’s participation in that process. EPA is seeking public input to inform future steps by the agency. Read the rest of this entry »
A recent report from the Environmental Defense Fund and Ceres says that strong fuel efficiency and GHG emission standards for freight trucks could slash fuel consumption by as much as 40 percent compared to 2010 levels, resulting in significant environmental and economic benefits.
In fact the report suggests that American businesses could save more than $25 billion if the National Highway Traffic Safety Administration and the U.S. Environmental Protection Agency adopt stringent fuel efficiency and greenhouse gas standards. The two agencies were tasked by President Obama to come up with proposed target standards for medium- and heavy-duty trucks by March, 2015. Read the rest of this entry »
Good news about the air we breathe is, well, good news indeed. Also rare. But there is some good news regarding ground level ozone, or smog, courtesy of research from Rice University and the EPA.
This can get a bit technical, but thanks to the EPA the difference between ground level ozone and high-altitude ozone, in simple terms, is: ozone is “good up high, bad nearby.” We need that high altitude ozone layer to protect the atmosphere and us. But ground level ozone, created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight, is harmful. Read the rest of this entry »
Fracking is getting heat—or at least a lot of attention—at the grassroots and at the federal levels. President Obama this month issued an Executive Order forming an interagency working group “supporting the safe and responsible development of unconventional natural gas resources.”
“Unconventional” in this case is hydraulic fracturing—aka fracking—a natural gas extraction method in which water, sand and chemicals are pumped underground at high pressure in order to fracture, or crack open, layers of rock, making oil and natural gas accessible. Fracking makes it easier to get at the large deposits of oil and gas from shale formations.
But many also contend that it is risky and, in effect, cruel and unusual punishment to the earth’s crust and water resources. Fracking can release harmful pollutants into the air and underground water tables. There is also alarming evidence that the process causes earthquakes, which apparently is what happened last year at a fracking site near Blackpool, England. Read the rest of this entry »
It took a while—20 years!—but the EPA’s historic decision to regulate mercury emissions are cause for a major celebration and at least a dollop of optimism that the U.S. is on the right environmental path heading into the new year. That is if the Republicans don’t mess it all up by winning the White House in November. (Writing that just sent a major chill up my spine.)
Not long ago I wrote about how a few miniscule drops of mercury can contaminate a 20-acre lake and the fish that happen to reside there, thanks to coal-fired plant emissions. That’s a major reason why the EPA’s decision to regulate the emissions of mercury, lead and other toxic pollutants from coal- and oil-fired plants is a major victory for the health and environmental welfare of the nation. And for jobs.
Please ignore the scare tactics from Big Coal and right-wing wackos about blackouts, job losses and energy security risks as a result of the rules. That’s their big lie and they are sticking to it no matter what.
“Congress ordered the EPA to regulate toxic air pollution more than 20 years ago when it passed the Clean Air Act Amendments of 1990,” said Rachel Cleetus, senior climate economist at the Union of Concerned Scientists. “The EPA has been regulating most industries up until now, except for the biggest polluters—coal and oil-fired power plants. The public health benefits far outweigh the costs. And contrary to the doomsday predictions of industry and their allies in Congress, the lights will stay on.” Read the rest of this entry »
Talk about turning logic on its head: Four right-wing, anti-big government groups contend the EPA is “abusing” air-quality laws because the agency’s MACT (maximum achievable control technology) utility rules will force coal-fired electrical plants to shut down, thus jeopardizing the security and reliability of the U.S. power supply.
A recent petition by the Institute for Liberty, Americans for Prosperity, Center for Rule of Law, and the Freedom Through Justice Foundation is asking EPA to “look at the facts on electric reliability and its Utility MACT rule, which the agency is rushing to finalize in November.”
The coalition’s petition contends the EPA is rushing to judgment and questions the EPA’s assumptions on electric reliability. “EPA has never taken reliability seriously,” it says. “The message of this petition is simple: slow down, do the job right, and do not put reliable electric service at risk.” Read the rest of this entry »
