New research has revealed the scale of the carbon-storage potential of the seabeds around Canada, conservation efforts must take this new data into account.

The most comprehensive assessment yet of a powerful greenhouse gas shows which countries are driving the increase, and which ones are successfully cutting emissions.

Around the world, coral reefs are suffering. But scientists in high-income nations are developing new ways to build coral resilience. We have a duty to share our skills and build capacity elsewhere.
Environmentalists have long been sceptical of carbon capture and storage, which began in the oil and gas industry. But there’s nothing else like it for storing emissions from industry.
Afforestation is one way to offset greenhouse gas emissions. Yet it is not always easy to navigate the different types of projects or methods available, and the possibility of greenwashing is ever-present.

Offsetting greenhouse gas emissions can be an effective tool for limiting global warming. But many offset projects fail to meet their GHG reduction targets.
The ruling could be a legal game-changer for small island nations that are trying to hold developed nations to account for the impacts of their greenhouse gas emissions.
A new report from the Transport Energy/Emission Research consultancy examines Australia’s New Vehicle Efficiency Standard, finding it was weakened by late changes.
The pursuit of ‘vanity height’ in skyscrapers is driven by aesthetic appeal and the status of being ‘the tallest’. Redefining how we measure building heights can help cut the environmental cost.
When it comes to storing carbon, alpine peatlands are powerhouses. But feral horse grazing and trampling tips the carbon balance in the other direction. We need to protect and restore our peatlands.

These electric aircraft take off and land vertically so they don’t need runways. And they promise a quieter, more accessible and less polluting form of short-distance air travel than helicopters.
Methane is a potent greenhouse gas that can leak from oil and gas wells, pipelines and landfills. Satellites can spot the releases fast enough to get them fixed and help protect the climate.
Solar engineering is designed to reflect some of the Sun’s ray back into space.

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?
Cattle emit a lot of methane, but they also provide livelihoods and environmental services.

Knowing which parts of Africa best help to store carbon means funding and policy efforts can be directed to protecting and increasing this carbon ‘land sink’.
Climate rallies, like this one in New York City in 2022, draw activists of all ages.
