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.
Most proposed solutions don’t address the systemic problems facing Eskom, in particular its parlous finances.
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?
Australian-designed technology will soon be responsible for 50% of all solar energy produced globally.
A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world's solar power.
You may be surprised to learn that the F1’s biggest contributor to the carbon footprint is not the cars themselves.
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.
Sasol is in an advantageous position. Will it make the right moves?
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.
Mangroves can store large amounts of carbon, but by themselves they’re not a solution to climate change.
Blue carbon stored in coastal ecosystems is important, but it's a poor fig leaf for Australia's abysmal record on emissions.
Our smartphones are made by rare earth metals, and consume large amounts of electricity.

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.

Countries still figure out their emissions by adding up all the sources, rather than measuring what's actually in the air.
Coal emissions are falling, but gas and coal use are strongly rising around the world.
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.
While many Australian households have solar power, our very large houses and wasteful use of building space are factors in our very high emissions.
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.
Rue des Tournelles, Paris, November 5, 2019. Four Voi scooters wait hopefully for potential clients, with a Lime and Dott sprawling nearby. Behind them, a Velib’ rider has made his choice.

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.
If the cement industry were a country, it would be the
third-largest emitter of CO₂ in the world.
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.
Nuclear power will likely remain part of the global energy mix.
Recent debates about the future of nuclear power in Australia make much of the potential of the next generation of reactors.
Turning a street tree into timber is much more respectful and useful than mulching it all.
City trees are often short-lived and many others get cut down in their prime. Turning them into mulch both wastes timber and releases stored carbon. A wood rescue program creates a more fitting legacy.
