EPA stops work on airline emissions standards

Agency’s move could violate federal environmental laws

Staff Report

A little more than a year after determining that greenhouse gas emissions from aircraft are a threat to public health, the EPA has stopped working on developing new standards for the air industry.

That’s not surprising, given that the Trump administration has sought to undermine nearly every rule set to limit heat-trapping pollution, but environmental advocates with the Center for Biological Diversity want to know more about the latest step backward by the EPA.

EDF report details risks to clean air, water programs

Staff Report

The Trump administration’s attempted dismantling of the EPA could have far-reaching consequences for Colorado, according to a new report issued by the Environmental Defense Fund.

The organization warns that the proposed 30 percent budget cut would affect public health and environmental cleanups by reducing the agency’s budget to levels last seen in the 1970s.

“The president seeks to roll back common-sense environmental safeguards that have protected the health and well-being of Colorado for decades,” said Elgie Holstein, EDF’s senior director of strategic planning, “This is not just an assault on an agency. It is an assault on public health and safety.” Continue reading “Trump’s EPA cuts threaten Colorado environment”

Wildfires in western Canada on near-record pace

More than 1 million acres burned so far

On July 11, 2017, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of wildfire smoke filling valleys in southern British Columbia. Actively burning areas, detected by MODIS’s thermal bands, are outlined in red. Hundreds of wildfires were burning in the province on that day, according to the British Columbia Wildfire Service.

Staff Report

Canada is on track for a near-record wildfire season this year. So far, there have been more than 500 fires just in British Columbia, burning across more than 1 million acres. Firefighting costs have already reached more than $172 million, and weeks of warm and dry weather will keep the fire danger high.

Most of the fires have been in three main areas, according to NASA, which has been tracking the burned areas via satellites. Most affected are the  Frasier Plateau  north of Vancouver, the Thomas Plateau, east of Whistler, and the region east of Kamloops. Continue reading “Wildfires in western Canada on near-record pace”

EPA takes Chrysler to court for cheating emissions tests

EcoDiesel engines on Ram trucks and Jeep Cherokees at issue in civil suit

Staff Report

The EPA may not be beating the climate change drum any more, but it apparently still wants to hold automakers accountable for emissions scams. This week, the agency announced it’s filing a civil complaint against Fiat Chrysler Automobiles, alleging that the company installed cheat software on almost 104,000 light duty diesel vehicles.

According to the EPA, the 3.0 liter EcoDiesel engines are equipped with software functions that were not disclosed to regulators during the certification application process, and that the vehicles contain defeat devices. The complaint alleges that the undisclosed software functions cause the vehicles’ emission control systems to perform less effectively during highway driving than on federal emission tests, resulting in increased emissions of harmful air pollutants.  Continue reading “EPA takes Chrysler to court for cheating emissions tests”

EPA chief Pruitt facing two separate ethics investigations

Anti-environmental agency head may have violated EPA policies and lied to Congress under oath

By Bob Berwyn

There’s little question that Scott Pruitt is the worst possible person to lead the EPA. He’s been involved in more than a dozen lawsuits against the agency and he’s called for it to be abolished completely, so it’s no surprise that he’s a target for bitter criticism from conservation groups. But his troubles are about to get much bigger than indignant tweets.

The Sierra Club has filed a formal complaint with the Inspector General of the Environmental Protection Agency demonstrating that EPA Administrator Scott Pruitt has violated the Agency’s Scientific Integrity Policy in multiple ways. The filing calls for an investigation into and resolution of Pruitt’s comments on carbon dioxide’s role in fueling the climate crisis.

He’s also now facing an ethics complaint by the Oklahoma Bar Association, which will look at whether Pruitt lied under oath to Congress. Continue reading “EPA chief Pruitt facing two separate ethics investigations”

West Coast states, cities, challenge Trump on climate policies

Leaders vow to fight effort to roll back Clean Power Plan

Staff Report

The Trump administration will reportedly soon unveil an executive order to try and undo climate policies developed under Obama, but West Coast states say they have intention of going along with that half-baked proposal.

Global CO2 emissions flat for 3d year in a row

U.S. emissions at 1992 level, according to IEA report

Staff Report

Carbon dioxide emissions from the world’s biggest economies — the U.S. and China — dropped in 2016 and didn’t grow in Europe, showing that economic growth can occur without an increase in heat-trapping pollution, according to the latest emissions report from the International Energy Agency.

Despite the slowdown in emissions from the power sector, CO2 levels are still climbing at a record rate, though, according to scientists who recently released a report showing that concentrations of the heat-trapping greenhouse gas increased 3 parts per million for the second year in a row. The concentration is now above 400 ppm, more than 43 percent more than pre-industrial levels. Continue reading “Global CO2 emissions flat for 3d year in a row”
