- Tue 23:23A bill making its way through the Kentucky legislature would govern CO2 storage in the Bluegrass State.

Pipe and seek – Canadian Prime Minister Mark Carney was aware of pipeline company South Bow’s plans to revive parts of the cancelled Keystone XL pipeline when he raised the idea with US President Donald Trump in October, Reuters reported. South Bow is evaluating a proposal to leverage existing infrastructure and permitted corridors in Canada to connect to US crude pipelines, a company spokesperson confirmed. US firm Bridger Pipeline has separately filed a proposal with Montana regulators to build a 1,038-kilometre pipeline from the Canadian border to Guernsey, Wyoming, capable of carrying up to 550,000 barrels per day of Canadian crude. The Canadian government said it is not involved in the South Bow proposal but added energy would form part of upcoming CUSMA trade agreement review negotiations.
- Tue 23:04The pace of issuance of Article 6-authorised credits under one of the major voluntary standards slowed in 2025, even as the number of project authorisations grew, according to a recent report.Â
- Tue 22:25Financing for post-wildfire reforestation in the southwestern US is unlikely to deliver meaningful climate returns beyond high-elevation mesic areas, as low seedling survival and warming sharply constrain carbon storage, new research has found.
- Tue 21:31California emissions from diesel and gasoline consumption in 2025 continued their year-on-year (YoY) decline in November, state data showed.
- Tue 20:26Pipeline purgatory – New York state regulators on Friday urged the Federal Energy Regulatory Commission (FERC) to dismiss a petition by Williams Companies to reissue a certificate for the 125-mile Constitution natural gas pipeline, Energy Wire reported. Williams cancelled the project in 2020 before reviving it last year. The state argued FERC should not reopen administrative review of the lapsed approval. Environmental groups said FERC lacks legal authority to reissue a vacated certificate. Williams contends no fresh application is needed, citing FERC's original 2014 approval for the pipeline that will connect Pennsylvania to New York and from there to New England.
- Tue 20:24Pumped up prices – California's goal to install six million heat pumps by 2030 faces a barrier the state's own climate strategy helped create: residential electricity prices that are nearly double the national average and rising faster than inflation, CalMatters reported. Researchers found that while households in the US South and Pacific Northwest would likely cut bills by switching from gas furnaces, many California homes – particularly larger properties in colder inland counties – would see costs rise, as electricity rates have grown at twice the pace of gas prices since 2001. The findings matter for California's broader decarbonisation push as buildings account for 13% of US GHG emissions, according to the US EPA.
- Colombian registry – As of Aug. 2025, 324 emissions reduction activities had voluntarily registered in Colombia's national registry, RENARE, representing 1.1 bln tonnes of CO2e of reductions in the aggregated crediting periods, the coordinator of the instrument at the Directorate of Climate Change and Risk Management of the Ministry of Environment and Sustainable Development (MADS), Jimena Gomez, said at a webinar last week. These activities apply to the voluntary carbon market or the carbon tax offset mechanism and span over 87 mln ha, which represents 76% of the continental country limits, the official said. Despite the RENARE platform still being under development, the website has gradually been reactivated and currently allows initiatives to register up to a feasibility phase, Gomez added.
- Tue 20:21Hot rock, cool data – Ormat Technologies last week signed a long-term power purchase agreement (PPA) with NV Energy to supply up to 150 MW of new geothermal capacity to support Google's data centre operations in Nevada, the company said. The projects are expected to come online between 2028 and 2030, subject to approval by the Public Utilities Commission of Nevada in the second half of 2026. The deal is structured as a multi-project portfolio under NV Energy's Clean Transition Tariff, with the contract term beginning when the first project reaches commercial operations and extending 15 years beyond the final project's start date.
- Tue 20:10A team of researchers has released what they describe as the first globally consistent daily fossil CO2 emissions dataset spanning more than five decades, a development that could materially improve the ability of analysts to disentangle short-term temperature effects from structural emissions trends.
- Tue 16:41The first issuance of credits using Verra’s new high-quality label for the afforestation, reforestation, and revegetation (ARR) is expected this year, a webinar hosted by the carbon registry heard Tuesday.
- Tue 16:40Modelling alliance – US-based soil carbon project developer Grassroots Carbon has joined Colorado State University’s Ecosystem Modelling and Data Consortium (EMDC) as an industry member, it was announced this week. The EMDC brings together scientists, NGOs, and industry to develop data-driven approaches to land management and climate mitigation, and its addition of Grassroots Carbon incorporates project-level soil carbon data into the methodologies underpinning carbon markets and NbS, press materials said. In January, Grassroots Carbon announced it had reached 2 mln credits delivered via its regenerative ranching programme.
- Tue 16:39Sunlight rules – A coalition of environment-focused groups has launched a governance platform this week to establish oversight principles for solar geoengineering research, amid rising political scrutiny of such technologies, E&E News reports. The Solar Geoengineering Research Governance platform will develop tools to standardise project reviews, improve public disclosure, and strengthen accountability in the coming months. Organisers said the initiative is designed to demonstrate that good governance is achievable within the sector.
- Tue 16:38Time squeeze – The US federal government and US EPA, as plaintiffs, this week stated their opposition to Vermont’s proposed organisation of a Mar. 30, 2026 motions hearing, arguing it would prejudice force a split of oral argument time with plaintiffs in a separate case. In a filing to the US District Court for the District of Vermont, the federal plaintiffs said the structure would limit their ability to argue constitutional and statutory claims against Vermont’s Climate Superfund Act and urged the court to hear the cases separately to ensure equal time.
- Tue 11:20SAF policy - Expanding SAF mandates to include CDR could support both emissions reductions and cost containment in the aviation sector, Noah Deich, former secretary of the Energy Advisory Board at the US Department of Energy, said in a blog post last week. Current SAF frameworks in jurisdictions such as the EU, Canada, and ICAO largely exclude carbon removal pathways, despite high costs across all SAF options and uncertainty over which technologies will scale. Allowing a limited share of mandates to include removals could diversify supply, support innovation, and improve political durability of SAF policies, while providing offtake opportunities for the CDR sector, Deich said.
