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.
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.
Reducing pollution will help stave off climate change but avoiding the worst effects means taking CO2 out of the atmosphere at large scale.

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.

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.
The Drax biomass plant in Yorkshire is the first in the world to pioneer carbon capture and some specialists see it as it has a bright future. But hold the rosy headlines.
Testing new ways to use this technology is underway in Japan.

Earth is fast approaching the red lines that scientists have urged temperatures cannot cross if we have any hope of avoiding catastrophic climate change. Here are the emergency measures we need.
Opportunities to help drive the energy transition are everywhere - even in Western Australia’s remote salt pans.

Nobel Prizewinning health researcher Peter Doherty reflects on the challenge of delivering a healthy climate for the world. From hydrogen power to wooden skyscrapers, the options are endless, but all require leadership.
Hydrogen fuel is just one opportunity for Australia in a clean-energy future.

The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
Without rapid and dramatic changes, the world will face a higher risk of extreme weather and other effects of climate change.

The UN’s panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
Painkillers and life jackets are two of the many products that depend on carbon dioxide.

Canada wants to move towards a green economy and meet its Paris Agreement targets, but it has also just taken ownership of a pipeline. How can the federal government deal with this paradox?
