Canada is already behind on tackling climate change and catching up will be expensive, but relying on carbon capture technologies is risky and expensive.
COVID-19 pandemic has seen the Morrison government abandon long-held dogma on debt and deficits. But on climate and energy, it's singing from the same old songbook.
It's encouraging that the federal government recognises its role in industry policy. But its choice to support some technologies is disappointing.
The government's latest energy plans are a failure of logic, and will lock in fossil fuel use for decades.
Energy Minister Angus Taylor is this week expected to release the government's first Low Emissions Technology Statement. It's likely to include ways to remove CO₂ from the air – but do they work?
We cannot rely on technology development alone to deeply cut Australia's emissions. Other policies and more money will be needed.
Changes to Australia's emissions reduction policies may do little more than channel taxpayer money to industry.
The lack of progress by governments in reducing global emissions means bold solutions across multiple fronts are now needed.
Carbon capture and storage has failed to put a dent in global emissions, and the world is running out of time.
The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can't do everything. But hydrogen fuel could complete the picture.
CO₂ will need to be removed from the atmosphere to avoid catastrophic heating. Can the process be incentivised?
An innovative method of carbon capture and storage could substantially reduce the emission of small industries while using geothermal energy to heat homes and thus replacing fossil-fuel energies.
Countries are not on track to meet Paris Agreement goals. A climate researcher argues that a range of technologies that take CO2 out of the air are needed.
Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
At best, planting trees won't be enough on its own to slow climate change. At worst, it's a dangerous distraction.
A new study lays out what must happen immediately for any hope of limiting global warming to 1.5°C.
A key tool for capturing and storing carbon may have been hiding in plain sight all along.
Carbon Engineering's clever harnessing of high-school chemistry is just a small step on the path to negative emissions.
George Monbiot talks with an ecologist about natural solutions to the climate crisis.
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
