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.

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.

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.

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.
Labor productivity doesn't matter as much as emissions productivity. Workers aren't a particularly finite resource.

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.
Carbon emissions from international air travel show no sign of abating. In the absence of a tax on jet fuel, are sail boats the best way to travel the world sustainably?
