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.
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.
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.
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.
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.
Despite voting to remain a member of an Australian coal lobby group, there are growing divisions between fossil fuel extractors and the larger energy industry.
