Your old phone could be a gold mine for the climate 10.05.2025 25:12
Drilling into the ground isn’t the only way to source metals for clean energy. You can also get them from castoff phones, laptops and TVs. It’s called urban mining. We speak with Maria Holuszko at UBC’s Urban Mining Innovation Centre about developing more efficient techniques for harvesting the gold, copper and other materials in old electronics. And Craig Wisehart of the Electronic Products Recyc...
What do Yo-Yo Ma, a glacier and a drag queen have in common? 07.05.2025 27:55
Pattie Gonia proves why climate action is a total drag, in the most fabulous way possible.

Energy superpower. Climate champion. Can the PM have it all? 03.05.2025 26:33
“Build baby build!” Post-election, the word ‘pipeline’ is popping up again. Mark Carney says he’ll speed up energy project approvals, honour the duty to consult with First Nations and also hit Canada’s climate goals. Eriel Deranger of Indigenous Climate Action worries these promises amount to “doublespeak.” She warns any plans to fast-track projects that impact Indigenous communities could face pr...
Who gets the water when the creek is running dry? 30.04.2025 27:50
Canada’s first local state of emergency due to drought was declared on the Sunshine Coast of British Columbia in 2022. The shortage was so bad, officials feared the region would run out of water for hospitals and fire departments. And the Coast has been under severe water restrictions for five of the last eight summers, a situation experts warn could become the norm. In her documentary, “Drought i...
Pope Francis made the climate fight a matter of faith 26.04.2025 25:32

Sweet solar silence in the land of the midnight sun 22.04.2025 28:01
In remote northern communities, diesel is king. But breakthrough solar energy projects are underway that could begin to reduce fossil fuel reliance. This year, the theme of Earth Day is renewable energy, so we’re taking you to Nunavut where people are adding solar panels to small off-grid cabins and others are working on community-scale solar projects — so the diesel generators can finally be turn...
What the parties are (and aren’t) saying about climate 19.04.2025 25:53
Climate hasn’t been a hot topic on the campaign trail, but did it come up in the debates? We hear about that from CBC’s Aaron Wherry. Then, we talk climate policy with NDP candidate Samantha Green. And, we hear what the Conservatives have been saying about climate and energy in this election.
It’s not easy being Green in this election 16.04.2025 25:43
The Green Party aims to be the environmental conscience of parliament. But its popularity has waned as people consider strategic voting in the face of other concerns – and as climate change slips as a priority for voters.

BONUS: Election time! Let’s talk about that other carbon tax 28.03.2025 13:12
Carbon pricing is a climate solution, but also a political football. Now that an election is underway and the consumer carbon tax has been scrapped, could the federal industrial price on carbon be the next wedge issue? Kate Ervine from Halifax’s Saint Mary’s University helps us go beyond slogans like “axe the tax” to understand what you should know about the industrial price on carbon.
Tasty, climate-friendly food that kids will make (and eat) 26.03.2025 27:53
Kids and veggies don’t always go hand in hand, but this after-school workshop is introducing plant-based cooking to children as a climate solution. It’s called EcoCooks.

Their research is taking place as growing geopolit...

Why a CO2 leak in Mississippi holds lessons for Canada 12.03.2025 27:43
Canada's oil and gas companies are hoping carbon capture and storage will be a big part of the country’s net zero plans. But shipping CO2 through pipelines to storage facilities can come with risks.

Eco-thugs be warned! You could be charged with ecocide 08.03.2025 25:35
There’s a push to see those responsible for intentional destruction of the environment tried in the International Criminal Court, just like war criminals.
