Why Canada needs a 'just transition' from fossil fuels

With the stroke of a pen Joe Biden cancelled the Keystone XL pipeline, and now calls are growing for a 'just transition' — a shift from fossil fuels to a low carbon economy that doesn’t leave workers behind. We look at the barriers and how it could work.

How climate change has put nuclear energy back on the table

Canada’s resource minister says there’s no path to net-zero without more nuclear development, and the push is on to develop small modular reactors. But uncertainties remain — and experts disagree whether they’re the climate solution we need.

The promise of trees as a climate solution

It's an idea that's been framed as a simple solution to a warming climate – plant more trees. On both sides of the border politicians of all stripes have promised to plant billions and trillions of trees - but how feasible is it to deliver and what impact would it really have?
