Microsoft, Walmart and a few other high-profile companies made news for scaling back their public climate commitments. However, a closer look at the numbers shows commitments are still booming.
Insulating attics, replacing windows and adding heat pumps can save money and reduce emissions − if residents can afford the upgrades. Carbon-offset purchases by local companies could help.
This week, nations are hashing out new goals for climate finance at the COP29 talks. Loss and damage is finally on the agenda – but the chance of major new funding is low
The time has come to develop Canada’s participation in international carbon markets.
As world leaders gather at COP29 to consider reducing emissions, the latest global carbon budget shows CO₂ emissions from fossil fuels are still going up, not down, despite some promising signs.
A deep dive into 866 public companies and 1,413 carbon projects reveals some twists in who relies on cheap offsets and who chooses to cut their own emissions instead.
We wanted to find out how much carbon and nitrogen is being released from the northern permafrost. Here’s the region’s first full greenhouse gas budget covering CO₂, methane, and nitrous oxide.
COP29 should end subsidies to fossil fuel companies, compel large-scale emitters to compensate affected regions and ensure that carbon taxes reflect the true cost of cleaning up pollution.
‘Climate scientists’ are often understood as being a block of experts with monolithic beliefs. A new survey sheds considerable nuance onto the beliefs and perceptions of climate scientists.
All of human civilisation emerged during unusually benign climate conditions. As temperature records fall and climate damage intensifies, we are beginning to see what happens when we leave it behind.
The board of directors should make sure a company fulfils its climate pledges – but some are more effective than others.
Pollution solutions start with public pressure, often in the face of industry pushback and slow-moving political responses.
Abating methane emissions and enhancing atmospheric removal offers an opportunity to rapidly mitigate warming.
The High Speed Rail Authority has publicly outlined plans that allow for some optimism that Australia could have these trains in the late 2030s.
There’s a risk that the belief that electric vehicles are much greener results in owners driving more often or faster, or using cars instead of public transport.
Human activities now account for two-thirds of all methane venting to the atmosphere – and our efforts to staunch the flow are not yet bearing fruit.
Emissions pathways act as a map of the future, showing us how to get from where we are to where we want to be.
Factories producing non-stick coatings for cookware aren’t properly limiting emissions of one of the most potent greenhouse gases, our research suggests.
The global average temperature could continue to hover around 1.5°C for several years.
