Buildings produce 25% of Australia’s emissions. What will it take to make them ‘green’ – and who’ll pay?

Australia’s commitments to cut emissions are on a collision course with urban growth. We need a much more comprehensive strategy to make the transition to a sustainable built environment.

Want citizens to care about climate change? Write them a cheque

Millions of people worldwide are either indifferent to a carbon tax or opposed. If citizens were motivated by potential carbon dividends, maybe politicians would finally take action on climate change.

What’s your beef? How ‘carbon labels’ can steer us towards environmentally friendly food choices

Most consumers underestimate the greenhouse emissions associated with different foods. But environmental labels, similar to existing nutrition information, can help us make lower-impact choices.

Emission targets: If there’s a (political) will, there’s a way

Achieving climate objectives is economically realistic, but won’t be possible without the support of a real transition strategy that is still lacking at all levels of government in Canada.

We can’t know the future cost of climate change. Let’s focus on the cost of avoiding it instead

For decades, economists have pondered the ‘social cost of carbon’ - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.

The Climate Clock: Counting down to 1.5°C

We are on track to reach 1.5°C of global warming within 16 years according to new data.

A wealth tax forces those responsible for climate change to pay for it

A wealth tax would put a price on past emissions and could be used to mitigate the negative effects of poverty, including vulnerability to climate change.

Chinese migrants follow and add to Australian city dwellers’ giant ecological footprints

Australian cities are world-leading – in the worst sense – for resource use and greenhouse emissions. China-born residents have embraced these consumption patterns, which is bad news for the planet.

How to make the liquefied natural gas industry more sustainable

Burning natural gas produces less greenhouse gases than coal or oil. But the methane emissions associated with natural gas production and liquefaction threaten to erode its environmental benefits.
