There’s more to sustainability than net zero. Using green ammonia for fuel and as a way to transport hydrogen could add to nitrogen pollution that already exceeds safe planetary boundaries.
Shipping companies have billions invested in fleets that were built to last decades. Now, the US is calling for zero emissions by 2050, and the EU is raising the cost of fossil fuel use.
Stopping the production of lab-grown food will be bad news for the environment.
An EV industry expert offers five reasons to be optimistic that the government’s ambitious proposed rules to clean up auto emissions can succeed.
Chlorofluorocarbons (CFCs) are also potent greenhouse gases which contribute to climate change.
CCS remains a ‘handy excuse’ for extracting more fossil fuels, our review indicates.
It’s a plant that is nearly impossible to obliterate, but new research reveals the best way of tackling Japanese knotweed in the most sustainable way.
The revised safeguard mechanism could form the basis of an economy-wide carbon price.
While the introduction of more climate policies across jurisdictions is good, synchronized policy decisions are better.
If electric cars are useful for the energy transition, they’re not without flaws and drawbacks and should not make us forget the need to reduce car use.
As the world waits with bated breath for the release of the latest UN climate report, let’s take a fresh look at the IPCC. What can we expect from the Synthesis Report on Monday evening?
All those Cinderella stories, buzzer-beating finishes and wild cheering sections have a high price tag – for the climate.
Labor has ruled out banning new fossil fuel developments. Even so, there are many climate deals the government and the Greens could strike
There’s no simple “yes” or “no” answer to whether we should produce more children when Earth is in such dire straits.
Evidence in Earth’s natural archives, from tree rings to seafloor sediments, points to one trend. Some climate models suggest another.
New Zealand is considering a plan to tax methane from cows. But while cows and cars both emit greenhouse gases, they don’t have the same impact over time.
We’re rarely aware of a company’s full environmental footprint.
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
California is one of the world’s largest economies, and it’s aiming for net-zero emissions by 2045. A transportation expert involved in the plan explains why it just might succeed.
