PJM emergency order - The US DOE issued emergency orders on Tuesday for grid operator PJM to dispatch more power generation from fossil fuel plants, as needed, despite environmental restrictions that are typically in place, citing expected demand as needed from an upcoming heat wave in the region. The emergency is set to end before midnight EDT on July 3. The Trump administration said the move is necessary to maintain grid reliability. PJM serves large swathes of the East Coast, including RGGI-participating states Delaware, Maryland, and New Jersey.

Fossil fuel friend - Maryland-based non-profit the Center for Environmental Accountability (CEA) filed an amicus brief in the case of Suncor Energy vs. County Commissioners of Boulder County, supporting the energy companies in their defense against the Colorado county's effort to collect damages for climate-related harms. The non-profit argued jurisdiction in the case is clear; federal common law precludes respondents' arguments; the US EPA's rescission of the Endangerment Finding does not affect the outcome of the case; and no court or jury "could feasibly address respondents' allegations".

Connecticut NbS evaluation – The Connecticut Department of Energy and Environmental Protection (DEEP) on Wednesday released an evaluation of its NbS initiatives. The evaluation analysed 10 different NbS best practices, showing how they are integrated into nearly 50 state programmes administered by multiple state agencies. DEEP’s evaluation found that NBS are generally well-integrated into its programmes. The evaluation also included recommendations that mirrored those of the draft evaluation, including: expanding natural and working lands modeling in GHG inventories; reviewing and integrating existing resilience funding and finance mechanisms; restoring support to discontinued NbS programmes; and developing a statewide NbS implementation roadmap and soil health plan.

Canada climate ambition vs. cost – Canadian Prime Minister Mark Carney said in a video statement that the departure by his Liberal government from the climate policies of his predecessor Justin Trudeau means emissions will be higher in the coming years than they would have otherwise been. A Dec. 2025 study from Canada's environmental ministry already found the country will reduce its emissions 21% from a 2005 baseline by 2030 in a status quo scenario, missing a 40-45% target, and environmental groups have challenged federal climate rollbacks. However, the prime minister said previous plans were overly costly and unsustainable, particularly amid an evolving and increasingly hostile geopolitical environment. Carney also made the case for expanding Canadian oil and gas exports, saying the world still needs a reliable source of fuel. The CBC reported Alberta is preparing for a major announcement this week about a proposed oil pipeline to Canada's West Coast envisioned under the Ottawa-Alberta carbon price deal, although further details around an announcement remain fuzzy.

US-based voluntary carbon standard Climate Action Reserve (CAR) finalised its revised permanence approach for long-term carbon storage on Tuesday.

Isometric has issued nearly 22,000 reforestation carbon credits to an Amazonian project from a Sao Paulo-based developer, the first such credits for both companies, they announced on Wednesday.

RGGI return complete - Virginia Governor Abigail Spanberger (D) formally signed into law legislation to see Old Dominion return to RGGI, the US Northeast and Mid-Atlantic power sector cap-and-trade programme. Speaking at the signing, Spanberger highlighted the RGGI credit for residential customers and small businesses included in Virginia’s biennium state budget following cost concerns expressed by some ahead of the state's return to the market. The governor also approved a budget deal reached recently with legislators that imposes a new energy tax on data centres but maintains a sales tax exemption for the industry. Finally, Spanberger's office said she signed a series of other bills intended to protect consumers from high energy costs and rising demand, including bills that: expand small-scale solar by raising a carveout for projects on rooftops, schools, churches, parking lots, landfills, and brownfields; require utilities Dominion Energy and Appalachian Power to develop voluntary demand flexibility programmes for high energy demand customers; and mandate investor-owned utilities to provide greater transparency on coal and oil generating units in rate proceedings.

Solar uncertainty – Canary Media reported Tuesday that uncertainty continues to cloud Connecticut's solar sector despite the state's recent enactment of legislation aimed at supporting deployment. The law, signed by Governor Ned Lamont (D) earlier this month, extends renewable energy incentives, authorises plug-in solar, requires automated residential permitting, and calls for a new community solar programme. However, developers and environmental groups said that regulatory uncertainty, local opposition, and other factors continue to weigh on the industry's outlook. The sector's concerns have also been reinforced by Eversource's decision to reject contracts for 54 MW of state-selected solar projects, citing unresolved uncertainty over state energy policy.

Quebec aims to increase the share of renewables in its energy mix to nearly 77% by 2050, from around 48% currently, under a newly published long-term energy strategy.

The revised corporate net zero standard from the Science Based Targets initiative (SBTi) could substantially increase demand for voluntary carbon credits over the coming decade, though actual growth is likely to depend on whether companies raise internal carbon prices and voluntarily increase credit purchases ahead of 2035, according to new analysis.

Airlines need to set more stringent near-term emissions reduction pathways and provide greater transparency on their transition plans under the voluntary Science Based Targets initiative (SBTi) in order to close the sector's emissions gap, according to an academic report.

Total California-registered accounts under the state's Quebec-linked compliance carbon market increased 1.5% during Q2 to surpass 830, data showed.

Largest renewable energy business - South Korea's SK Inc, SK Group's holding company, has signed a deal with US investment firm KKR to establish a KRW 2 trillion ($1.3 bln) joint venture for renewable energy development, eyeing growing power demand in the country, they announced. The venture will be South Korea’s largest renewable energy business, with around 1.7 GW of capacity currently in operation and a development pipeline that will bring the total capacity to 10 GW, enough to 100 large-scale, 100 MW-class data centres.

Colombia, a major player in voluntary and international environmental markets, is nearing the end of a presidential term that dealt the sector a major blow – but while the incoming president has raised hopes of a revival, questions remain over implementation.

Ready to go – Strategic Biofuels received a finalised Class VI CO2 injection permit in Louisiana for its underground storage project in Caldwell Parish, the company said on Tuesday. The Louisiana Department of Conservation and Energy had issued a draft permit to the renewable fuel developer in March. The permit includes multiple injection wells – a first of its kind model in the state. The project pairs carbon capture and storage with biomass-based generation from sustainable forestry feedstocks.

Endangerment finding fight - The Alliance for Automotive Innovation filed a motion in opposition to a proposed stay the US EPA's undoing of the Endangerment Finding by youth challengers of the move, arguing that going back and forth between standards would increase difficulties for the industry, an argument echoed by states and federal officials and other groups also opposed to the stay. On the other hand, challengers to the rescission argued in recent filings that the agency's administrative record should be adjusted to include supplemental comments made during the regulatory process, while petitioners also requested a 10-day extension to file their reply in support of staying the Endangerment Finding repeal.

Democrats in the US Senate and House of Representatives have reintroduced a legislative effort to fund advanced clean shipping technology and infrastructure.
