A long-term housing stimulus package that focuses on retrofitting to cut energy demand would also help households repay the debts being accumulated during this crisis.
Travelling to conferences and meetings has become a way of life for many of us – and has driven up emissions. Now COVID-19, not climate change, is forcing us to explore and develop alternatives.
Carbon accounting isn’t always simple, so it’s important to make it easier to measure and reduce emissions at the local level. And that’s ultimately the starting point for global climate action.

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.
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.
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.
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.
