Welcome back: Is carbon dioxide a pollutant? A small but vocal group of researchers, authors and government officials say it is time to change the definition, the WSJ's Eric Niiler writes.

The Trump administration is asserting that CO2 isn’t a threat to public health, as part of an effort to undo some of the Environmental Protection Agency’s responsibilities for regulating emissions. Redefining CO2 is central to the EPA plan, which would eliminate the so-called endangerment finding that followed a 2007 Supreme Court ruling that greenhouse gases including CO2 should be considered pollutants and federal regulators must determine whether they endanger public health. 

The Energy Department completed a 141-page review of the science of climate change last month that is the scientific foundation of the EPA’s effort to roll back existing emissions rules. A lawsuit filed last week by the Environmental Defense Fund and the Union of Concerned Scientists in a federal-district court in Massachusetts contends that agency officials violated federal rules that require them to hold open meetings and disclose the report’s authors beforehand.

Public hearings start this week, kicking off what is likely to be a lengthy legal battle over whether the government will continue to regulate greenhouse-gas emissions from vehicles, power plants and other industries.

DOJ Sues California Regulator Over Trucking Emissions Standards

The Justice Department announced a lawsuit Friday against California’s air regulator, the latest move in the Trump administration’s sweeping attacks on electric vehicles, WSJ Pro Sustainable Business's Clara Hudson writes.

The lawsuit takes issue with the California Air Resources Board’s emissions standards for trucks, carried out through a partnership with heavy-duty truck and engine manufacturers.

Earlier this year, California’s air regulator dropped a trucking request to the Environmental Protection Agency over fears that the Trump administration would deny it. The regulator sought a waiver to allow it to mandate that truckers buy battery-electric and hydrogen fuel cell trucks, in an effort to cull the amount of diesel-powered trucks. In June, Trump signed legislation that put an end to California’s EV sales mandates and diesel engine rules.

Last week, truck makers including Daimler and Volvo sued the state to stop it from enforcing emissions standards, arguing that they no longer hold.

FASB Sets New Accounting Rule on Environmental Credits

The Financial Accounting Standards Board voted to set new requirements on how companies account for environmental credits such as renewable-energy certificates and carbon offsets, while dialing back the extent of disclosures it had proposed last year, WSJ Pro's Mark Maurer reports.

Last week, the standard setter voted to require U.S. public and private companies to apply one model to various credits that companies obtain for their compliance programs or voluntary use.

The new rule covers carbon offsets, cap-and-trade programs and renewable-energy credits. Companies obtain certain environmental credits for producing or selling products aimed at removing or reducing pollution or generating energy from renewable sources. Businesses are also granted emissions allowances and cap-and-trade credits from regulators.

Companies will have to recognize an environmental credit when the credit likely will be used to settle an obligation or be sold to a customer. They will need to record the value of the credit at its cost. If they don’t expect to settle the liability, they also have to test whether to reduce the value of the credits on the balance sheet.
