Making ammonia produces almost 2% of global carbon dioxide emissions.
Carbon accounting isn't always simple, so it's important to make it easier to measure and reduce emissions at the local level. And that's ultimately the starting point for global climate action.
The deluge of opinions and proposed solutions to South Africa's energy crisis reflects corporate and political interests.
CO₂ will need to be removed from the atmosphere to avoid catastrophic heating. Can the process be incentivised?
A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world's solar power.
F1 has promised a move to 'credible offsets and breakthrough C02 sequestration programs'. But there's a persistent lack of clear detail in the how, what and where.
There is a golden opportunity for South Africa to transition from being a key contributor to global warming to becoming a key contributor to global emissions reductions.
Plastic packaging isn't always the enemy and don't be fooled by organic labels.
Blue carbon stored in coastal ecosystems is important, but it's a poor fig leaf for Australia's abysmal record on emissions.
Last year, it was estimated data centres around the world generated the same amount of carbon emissions as created by the global airline industry's fuel usage.
Sport tips for the Ontario government on how to make good climate change policy.
Countries still figure out their emissions by adding up all the sources, rather than measuring what's actually in the air.
Carbon emissions will hit a record high for the second year in a row, but there is a small silver lining: the rate of emissions growth has slowed dramatically.
There's no question Tesla's Cybertruck will face stiff competition in the electric pickup truck market. Here's why it has the edge.
Effective engineering solutions to tackle climate change already exist but there is a desperate lack of conviction to address the emergency.
Making better use of existing building space is a neglected but essential way to cut our carbon emissions. The key is human behaviour. Good low-carbon citizens will help create good low-carbon cities.
In major cities around the world, dockless scooters and bikes are everywhere, yet the companies themselves are often breathtakingly short-lived. Basic economic concepts give us clues why.
Instead of boycotting palm oil, source it from pastureland and not recently logged forests.
The cement needed to make concrete – the most widely used man-made material – is a major source of global emissions. Researchers are working on a green replacement that could transform the sector.
Recent debates about the future of nuclear power in Australia make much of the potential of the next generation of reactors.
