The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.

Gas mining is expanding across Australia, and has been touted as part of the answer to cutting emissions. But there is evidence that this rollout will pose significant health and environmental risks.

Reducing emissions doesn’t have to conflict with a growing economy, as these 18 developed nations show.
While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.

Whether to attending a conferences or giving in to a meeting, the global research community is keen on air travel. That’s a habit that needs to change.

Buildings are responsible for 40 per cent of energy-related carbon dioxide emissions worldwide. Efforts to reduce emissions should no longer be voluntary.
The solar boom continues, but not necessarily because of government policy settings.

Australia’s government insists it is on track to surpass its emissions reduction commitments under the Paris Agreement. But while that may be true, it will only happen with some clever accounting.
Across our growing cities more and more buildings are going up, as are their emissions.

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.
If citizens think they’ll personally and financially benefit from a carbon tax, maybe politicians would take action.

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.
Fire danger conditions are worsening in many areas of Australia.

Three years after the Paris Agreement, negotiators have finally agreed (most of) the rules for its implementation. But there is still no way to compel countries to deepen their climate ambitions.
Delicious, nutritious… and emissions-intensive.

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.
Steel mills, like this one in Hamilton, Ont. emit greenhouse gases. Ontario must reduce its emissions from 161 megatonnes to 143 megatonnes by 2030.
