The 'used water' that flows from our showers, dishwashers and toilets isn't a waste to engineers – it contains valuable materials. The challenge is recovering them and turning them into products.
The coal, oil and natural gas industries are also connected with human rights violations, public health disasters and environmental devastation.
A new pathway for the global energy transition shows how the world can meet the Paris Agreement's 1.5C warming goal without relying on carbon capture and storage, by creating a renewable gas industry.
Raising livestock has clear impacts on the environment, but contrary to what many critics say, it is not the biggest driver of climate change.
The US government is set to make it easier for oil and gas firms to leak methane into the atmosphere.
Food systems must be transformed to produce more nutritious food with a lower environmental footprint.
This new and more accurate estimate means that replacing coal with natural gas doesn't do as much to reduce climate change as it should.
New research has suggested a fresh way to account for greenhouse gases with different lifetimes in the atmosphere.
Natural gas is widely viewed as a clean fuel, but methane, its main component, is a powerful greenhouse gas. Two experts propose a plan for detecting and cutting methane leaks across North America.
The European Investment Bank's funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
A tax on beef isn't likely to achieve the intended outcome of reducing greenhouse gas emissions. Instead, it could create a spate of unintended consequences.
Canadians are a wasteful bunch, especially during the holidays. Redesign your holidays this year to cut back on garbage and food waste.
New experimental results on methane may help us to uncover whether Uranus really is the coldest planet.
Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
Landfills produce huge amounts of methane. Many of the bigger operators capture it to turn into energy, but they’re wasting about 80% of what’s available. It’s time Australia stepped up.
Canadians love to paddle on them and camp beside them, but our boreal lakes offer more than just peace and beauty. They could provide clues to how life on Earth began.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.
Why use satellites to study Earth's climate? Researchers leading a new mission explain how images from space will help them analyze which parts of the Americas soak up the most carbon.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
