Nuclear power isn't needed to meet Ontario’s electricity needs. And the absence of nuclear power won't have any impact on emissions in Ontario's energy sector.
Blue carbon stored in coastal ecosystems is important, but it's a poor fig leaf for Australia's abysmal record on emissions.
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.
Divestment doesn't affect global demand for oil, it just transfers power to state-run oil companies – which have higher carbon footprints. But there are other things we can do.
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 the same decade we are supposed to be cutting emissions under the Paris goals, our coal production is projected to increase by 34%.
Measurements and modelling have found nitrous oxide emissions, a greenhouse gas 265 times more potent than carbon dioxide, are significantly higher than previously reported.
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.
There are plenty other good reasons to stabilise the global population.
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.
New research shows that warming by more than 2°C could be a tipping point for Antarctica's ice sheets, resulting in widespread meltdown and changes to the world's shorelines for centuries to come.
Taxi drivers are exposed to twice the level of pollution compared to other drivers.
The nutritional, financial and environmental cost of an average family's weekly food waste is shocking. It equates to five adult meals, 143 showers, $18 and 23 kg of CO2.
Ahead of the UN climate summit, we take stock of the world's best and worst performers on climate action - including some surprise success stories.
Scientists from all over the world agree that the impacts of climate change will get worse, unless action is taken now.
The UN has asked world leaders to bring concrete climate action plans to this week's summit - and Australia is likely to cop heavy criticism.
Despite the overwhelming evidence that electric vehicle technology can deliver huge benefits, misinformation continues to muddy debate. Let's look at the facts.
Putting all of our eggs in the net zero basket is merely kicking the can down the road.
It’s official. The outlook for the Great Barrier Reef has been downgraded to “very poor”, and the window to act is closing.
