Though a series of investigations seem to have exposed the carbon market as an ineffective answer to climate change, the U.S. federal government's new guidelines aim to restore confidence in the controversial climate solution.

Half of all new cars are now SUVs, and even though approximately 20 per cent of them are hybrid or electric vehicles, rising emissions from the vehicles have been cited for causing as much as a fifth of the increase in global carbon dioxide emissions.

These charts show where Canada and our provinces are in the global EV race compared to the U.S., China and European nations … and critically, how that compares to our growing fossil-fuelled fleet.

Despite decades of global efforts to prevent a full-blown climate crisis, the primary driver of it — CO2 — continues to pile up in our atmosphere at an accelerating rate.

A beer maker in Dartmouth has found a way to save money and help the environment by reducing the use of a gas critical to the brewing process.

A startup is zapping seawater with electricity to extract and store away carbon, but scientists remain skeptical.

Advocates in the United States believe the long-awaited farm bill could help fix that.

The European Court of Auditors said the 27-nation bloc must “shift up gear” to come close to a zero-emissions car fleet, with electric vehicles playing a crucial role.

Visiting Alaska is an emissions-heavy prospect. An innovative program in Juneau has tourists ease that by helping buy heat pumps for locals.

Oysters stabilize shorelines, trap carbon-rich sediment, and help marshes grow.

One of Canada's largest biodigesters is taking shape in a field outside High River, Alta., raising with it a growing global debate over natural gas, cattle farming and greenwashing  The project will house a machine that transforms organic matter like cow manure or food waste into biomethane gas.

A new study reaffirming that global climate change is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather.

New federal research suggests greenhouse gas emissions from the Alberta oilsands may be significantly underestimated, adding to a growing pile of studies that say our understanding of what is going into the atmosphere is incomplete.

One of Canada's fastest-growing sources of emissions is the extreme greenhouse gas leaking from our businesses and homes. Barry Saxifrage takes us on a chart-packed tour of one of our least-known climate threats.

By betting it can solve its emissions problem with carbon capture and storage, Canada's oil and gas industry risks saddling itself with expensive stranded assets, a new report argues.
