New research shows Ontario doesn’t really need nuclear energy, and its absence would not have an impact on emissions in the province’s energy sector. (Ferdinand Stohr/Unsplash)

Ontario can phase out nuclear and avoid increased carbon emissions

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.
Coal emissions are falling, but gas and coal use are strongly rising around the world. EPA/SASCHA STEINBACH

Global emissions to hit 36.8 billion tonnes, beating last year’s record high

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.
While many Australian households have solar power, our very large houses and wasteful use of building space are factors in our very high emissions. Jen Watson/Shutterstock

Making every building count in meeting Australia’s emission targets

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.
If the cement industry were a country, it would be the third-largest emitter of CO₂ in the world. Joe Mabel/Wikimedia

Green cement a step closer to being a game-changer for construction emissions

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.
During the Pliocene, up to one third of Antarctica’s ice sheet melted, causing sea-level rise of 20 metres. from www.shutterstock.com

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 metres in coming centuries

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.
Research shows that the average Canadian household generates about three kilograms (or almost six pounds) of avoidable food waste per week. (Shutterstock)

Reduce your food waste to save money, boost health and reduce CO2 emissions

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.
