Trump loosens EPA refrigerant phaseout rules

Trump announced a rollback of two EPA refrigerant rules, delaying deadlines for grocery and air-conditioning companies to cut hydrofluorocarbon use and exempting transport companies from repairing HFC leaks. EPA Administrator Lee Zeldin and major grocery executives backed the move, while Trump said it would save more than $2.4 billion and lower grocery and cooling costs. Grist reported that economists and former EPA officials say the savings claim is implausible and that the rollback could add 68 million metric tons of CO2e by 2050.

Why it matters

It weakens a major super-pollutant phaseout and could raise emissions without materially lowering food prices.

Trump directs $700 million to coal plants

Trump announced $700 million in Defense Production Act grants for more than a dozen existing coal-fired power plants, along with funding tied to a new coal export terminal in Oakland and a restarted plant in Maryland. The package also keeps selected coal units operating across 10 states and includes two new coal plants in Alaska and West Virginia. Environmental groups say the plan will increase pollution and health harms, and the EPA separately moved to change an Obama-era emissions-reduction plan affecting a Wyoming power unit.

Why it matters

It is a direct federal push to extend coal generation just as climate and air-quality rules are being relaxed.

GHG Protocol tightens corporate renewable claims

The GHG Protocol, used by most organizations for voluntary emissions reporting, is finalizing a Scope 2 update that would move corporate renewable electricity accounting from annual certificate matching to hourly matching with stricter deliverability requirements. Draft guidance is planned for 2026, finalization for 2027, and implementation for 2028, with existing long-term PPAs expected to be grandfathered. The shift would weaken many low-cost REC-based 100% renewable claims and raise procurement costs, especially for cross-border unbundled certificate strategies.

Why it matters

It could materially change how companies claim renewable electricity and how much they pay for compliance-grade clean power.

Still unclear

OPEN QUESTION

Will HFC rollback lower grocery bills?

The administration's claim depends on whether refrigerant compliance costs actually affect retail prices.

OPEN QUESTION

How will corporate buyers meet hourly matching?

The Scope 2 shift could force expensive procurement changes and expose weak renewable claims before 2028.
