- 1Food waste emits five times more greenhouse gases than aviation●Rotting food waste emits 5 times more greenhouse gases than planes
New figures highlighted by UN News show that rotting food waste produces five times more greenhouse gas emissions than the entire aviation industry. As food decomposes in landfills it releases methane, a potent warming gas. The report has reignited calls to cut food waste as a fast, low-cost way to reduce emissions and meet climate targets.
- 2Permafrost and wetland emissions could amplify climate change by 30%▼Permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30%, study finds
A new study finds that emissions from permafrost thaw, wetlands, wildfires and freshwater systems could amplify climate change by up to 30%, over and above human-caused emissions. These natural feedback loops release additional carbon dioxide and methane as the planet warms, meaning current climate models may underestimate future warming. Researchers warn this strengthens the case for faster emissions cuts.

Kathairos Solutions is being highlighted for technology that eliminates emissions from pneumatic controllers, a common source of methane leaks at oil and gas well sites. The system, which uses liquid nitrogen to power controllers instead of natural gas, is drawing attention as operators face tightening methane regulations and emissions reduction targets across the energy sector.
- 4Blue pigment catalyst converts CO₂ directly into methane▼New potential for mitigating climate change: blue pigment catalyst turns CO₂ directly into methane i
Researchers have developed a blue pigment-based catalyst that converts carbon dioxide directly into methane, offering a new potential pathway for mitigating climate change. The approach could turn a major greenhouse gas into a usable fuel source, drawing attention as scientists search for practical carbon capture and utilisation technologies.
- 5Trump Administration and Qatar Warn EU Methane Rules Threaten Energy Security▼Trump Administration, Qatar Say EU Methane Rules Threaten Energy Security
The Trump administration and Qatar have warned that the European Union's methane emissions regulations could threaten global energy security. The EU rules require imported oil and gas to meet methane standards, affecting major exporters. Both Washington and Doha argue the requirements could disrupt energy supplies and raise costs, setting up a transatlantic dispute over climate regulation and trade.
- 6Philippines steps up fight against methane and HFCs▼# Philippines The Philippines is stepping up efforts to curb methane, black carbon and hydrofluorocarbons (HFCs) as part
The Philippines is intensifying efforts to cut methane, black carbon and hydrofluorocarbons as part of its goal to reduce and avoid greenhouse gas emissions by 75 percent under its 2026 Nationally Determined Contribution. The move targets potent short-lived climate pollutants alongside carbon dioxide, aligning the country with international climate commitments.
- 7SpaceX's Merlin and Raptor engines compared▼Merlin Vs. Raptor: How Do These SpaceX Rocket Engines Compare?
A comparison of SpaceX's two main rocket engines, the Merlin and the Raptor, is drawing attention. Merlin, which burns rocket-grade kerosene, powers the Falcon 9 and Falcon Heavy, while the methane-fuelled Raptor drives the Starship program. The discussion focuses on how the engines differ in fuel, design, thrust and reusability, and what those trade-offs mean for SpaceX's current and future missions.
- 8Arctic permafrost thawing and releasing heat-trapping gases▼Arctic permafrost is thawing and leaking heat-trapping gas into the atmosphere
Arctic permafrost is thawing and releasing heat-trapping greenhouse gases such as methane and carbon dioxide into the atmosphere, adding a new driver of global warming. Scientists warn the process could create a feedback loop: warming temperatures melt more permafrost, which releases more gas, which accelerates warming further.
- 9California launches new satellite to track methane emissions●California gets a new eye in the sky to track planet-warming methane https:// slrpnk.net/post/43371292
California has gained a new satellite dedicated to monitoring methane, the potent greenhouse gas driving global warming. The orbital sensor is designed to spot leaks and emissions sources from space, giving regulators and researchers a sharper picture of where planet-warming pollution originates and helping hold polluters accountable.
- 10Philippines seeks $5 million UN fund to fight super pollutants●PH targets $5-M UN fund to tackle ‘super pollutants’
The Philippines is targeting a $5-million United Nations fund to address so-called super pollutants, highly potent greenhouse gases such as methane and hydrofluorocarbons that warm the planet far faster than carbon dioxide. Accessing the fund would help the country finance measures to cut these emissions. The move highlights growing attention in Southeast Asia on short-lived climate pollutants as part of wider climate action efforts.
- 11California launches new satellite to track methane emissions▼California gets a new eye in the sky to track planet-warming methane
California has gained a new satellite dedicated to monitoring methane, the potent planet-warming gas, according to the Los Angeles Times. The orbital tool is intended to spot sources of methane leaks across the state and beyond, giving regulators and researchers better data to curb emissions from oil, gas and agricultural operations.

The European Union is reportedly considering postponing its methane emission rules for the energy sector as rising energy prices put pressure on policymakers. The proposal would delay requirements aimed at cutting methane leaks from oil and gas operations, drawing concern from climate advocates who see the rules as a key part of the bloc's emissions strategy.
