New report from @Earthworks found major methane leaks at New Mexico oil & gas facilities over a year– but very few of the leaks were reported to the state. It’s more evidence @NMEnvDep needs to finalize their strong proposal for monitoring super emitters: capitalandmain.com/satellite…
Global concerns over energy security are only growing. On @ForeignPolicy’s podcast, EDF’s @MarkSBrownstein explains why diversifying energy supply with electrification and cutting oil and gas methane emissions are key to sustainable economic growth. 🎧 bit.ly/4ei8Uow

Because of Texas’ immense solar, wind and battery resources, the state was able to cruise through record-breaking temperatures and electricity demand this summer. Read more: blogs.edf.org/climate411/202…
ALT The image is an infographic from the Environmental Defense Fund highlighting clean energy usage by the Texas grid during the summer. It shows a 94% rate of the grid being powered by majority clean energy for at least one point each day. Three calendars for June, July, and August indicate days with over 50% and under 50% clean energy in blue and green. A graphic of Texas and wind turbines is at the bottom right.

Rolling back EPA methane standards would waste American energy, says EDF’s @jonwgoldstein.
Meanwhile, states producing U.S. oil and gas, like CO, are strengthening #CutMethane rules because they know it’s good for business and communities. @CPRNews: cpr.org/2026/10/07/trump-loo…
An EPA methane repeal is “not going to benefit Americans,” EDF’s Nini Gu told @thenewmexican.
Rolling back federal methane protections would waste more energy, increase methane pollution and put the health of communities at greater risk. Read more. ⬇️ santafenewmexican.com/news/l…
Africa loses ~ 29B cubic meters of gas each year to methane leaks, venting and flaring. EDF's Suzanne Brady and Africa Practice's Agwu Ojowu explain how cutting waste can strengthen energy security, cut emissions and support economic growth.

As Zeldin previews a federal methane rule rollback, EDF’s @jonwgoldstein says EPA “should not give oil & gas companies more room to waste a domestic resource.” States like CO and NM are already showing that strong #CutMethane performance is possible. sourcenm.com/2026/10/07/epa-…
More than 4,500 medium- and heavy-duty electric trucks were ordered in September, the largest monthly total of 2026 so far. 📈

As Americans face rising energy costs, @EPA wants to let oil and gas companies waste even more.
EDF's Nini Gu at a New Mexico rally: People living near oil and gas operations will pay the price, not big polluters.

Hydrogen's climate benefits come down to how it's made, where it's used and how well its emissions are managed. A recent EDF study finds it pays off most in hard-to-electrify sectors like steel and fertilizer production. Learn more: 🔗blogs.edf.org/energyexchange…
NEW: Zeldin's EPA is poised to roll back crucial methane protections, giving corporations a free pass to pollute.
The bottom line ➡️ Weakening methane protections won't lower energy costs for consumers. It just means more wasted energy and dirtier air. edf.org/Zu34
CO regulators kept their commitment to fully adopt existing source methane standards under the 2024 EPA rule, “showing that states can move forward, cut pollution and protect communities with strong, evidence-based rules," says EDF's Nini Gu. 🔗 cpr.org/2026/09/22/colorado-…

IEEJ was pleased to support the Canada-Japan exchange hosted by the Embassy of Canada to Japan in Tokyo.
Toshiyuki Sakamoto, IEEJ, delivered opening remarks following Chargé d’Affaires Laurie Peters, and Hiroshi Hashimoto, IEEJ, served as moderator for Panel 1.
The discussion focused on the links between climate, trade, and energy security, including methane performance and LNG.

A strong methane win for states. 🤝 Colorado has fully adopted methane standards under the 2024 EPA rule, a great opportunity to quickly reduce emissions and an encouraging sign for other states to follow. More from EDF's Jon Goldstein. ⬇️
