On Wednesday, 17 US states together filed a legal challenge against the United States Department of Energy (DOE) over efforts to remove or shrink existing climate change regulations.

New York Attorney General Eric Schneiderman (pictured center at top), who leads the coalition, claims the federal government has a legal obligation to control and monitor carbon dioxide emissions based on scientific evidence indicating their contribution to climate change.

"The law is clear: The EPA [Environmental Protection Agency] must limit carbon pollution from power plants," Schneiderman said in a statement announcing the lawsuit.

"Energy efficiency standards are vital to our public health, our environment and consumers. This is yet another example of how the Trump administration's polluter-first energy policy has real and harmful impacts on the public health, environment - and pocketbooks - of New Yorkers."

Trump has consistently claimed that current US climate change laws do not offer worthwhile environmental benefits and instead unnecesarily obstruct domestic energy production and job creation.

Among Trump's recent executive orders: Rolling back Obama's climate policy linchpin, the Clean Power Plan

Since taking up his role, the current chief of the EPA, Scott Pruit, has publically denied the scientific consensus linking human activity to climate change. Pruitt is currently under investigation - by the Oklahoma Bar Association over an ethics complaint, and also internally by the EPA's science integrity office over his remarks that carbon dioxide is not the main contributor to climate change.

The coalition includes the states of California, Connecticut, Delaware, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, New Mexico, Oregon, Rhode Island, Vermont and Washington, as well as the District of Columbia and smaller localities.

Obama's climate change legacy under attack

Last week, President Donald Trump signed a controversial executive order to roll back Obama-era climate change regulations, including the Clean Power Plan which requires states to reduce carbon emissions from power plants.

Under the plan, energy efficiency rules were originally expected to be published in the Federal Register and come into effect on March 20 this year. However, they have since been pushed back to September 30 by the DOE under Trump.

The latest executive order requires the EPA to "suspend, rescind, or revise" the regulation based on an assessment. The EPA consequently filed a legal motion with the US Court of Appeals for the District of Columbia Circuit to postpone continuing court proceedings in order for the review to take place.

The 17-state coalition has asked the court to disregard EPA's request, claiming "nothing the EPA has proposed to do obviates the need for this court's review."

Schneiderman's office said Trump's actions violate "both the federal Energy Policy and Conservation Act and Administrative Procedures Act" by preventing required energy efficiency standards for a range of consumer products, such as ceiling fans, by failing to publish them in the Federal Register.

Multiple lawsuits expected

Trump's fossil administration Activists ready for a fight As climate deniers are poised to serve in prominent positions of Trump's administration, environmentalists have taken to the streets amid worries they could roll back environmental protections. Trump himself, who initially called climate change a "hoax," eventually conceded "some connectivity" between humans and climate change, and has now said he is keeping an "open mind" on the issue.

Trump's fossil administration Scott Pruitt: Fox in charge of the henhouse Pruitt is poised to become the head of the Environmental Protection Agency - an agency he repeatedly sued since becoming Oklahoma Attorney General in 2011. He opposes the Clean Power Plan, aimed at reducing carbon emissions. He has also blocked implementation of the Clean Water Rule, which expanded protection for bodies of water and requires polluters to clean up wastewater.

Trump's fossil administration Rex Tillerson: From big oil straight to politics Secretary of State nominee Tillerson worked for petroleum giant ExxonMobil for more than 40 years. During his confirmation hearing, when pressed, he acknowledged climate change risks. He said the increase in greenhouse gases is "having an effect," but added "our ability to predict that effect is very limited." ExxonMobil is accused of covering up climate research over several decades.

Trump's fossil administration Rick Perry: Friend of fossil fuels Environmentalists are concerned that as Secretary of Energy, the former Texas governor will boost oil and gas rather than focusing on renewables. In the past, Perry said he intended to axe the whole energy department. He has called global warming a "contrived phony mess." He's likely to support the controversial Dakota Access Pipeline. However, Texas did increase wind power production under Perry.

Trump's fossil administration Ryan Zinke: Climate change waffler Zinke, an ex-Navy SEAL commander from Montana, keeps changing his position on climate change. Initially in favor of climate protection, he later denied it even exists. At his confirmation hearing he told Senate, "I don't believe it's a hoax." As head of the Interior Department, he would oversee about a fifth of all US land - and make decisions about coal mining, and drilling for oil and gas. Author: Sarah Steffen



The Trump administration's stance on clean energy and climate change has provoked strong criticism from a number of state organizations and activists.

On Monday the Sierra Club, Natural Resources Defense Council (NRDC)and Earthjustice also announced their intentions to file a separate joint lawsuit against the DOE.

In a statement, Earthjustice accused the federal government of "needlessly delaying a raft of commonsense energy-efficiency measures."

"It is past time for the DOE to take the simple action of publishing these completed rules so we can all start to reap the benefits," said Earthjustice attorney Timothy Ballo.

Schneiderman's office also wrote on Monday that newly-appointed DOE secretary Rick Perry has 60 days to publish energy efficiency rules in the Federal Register, or a second lawsuit will be filed.

The states' lawsuit is the latest of a series of legal actions over climate change in the US. A group of American youths has been moving forward with their lawsuit accusing the United States government of endangering them by failing to curb climate change.

Separately, the Conservation Law Foundation is suing Exxon Mobil, alleging "climate deceit" in a decades-long cover-up over the impacts of climate change, which they say is endangering communities.
