The importance of critical minerals should not condone their extraction at all costs

The temptation to justify critical minerals mining at all costs is a dangerous fallacy. The social and environmental impacts of poorly mined critical minerals are dire.

Thermoelectric technologies can help power a zero-carbon future

Human societies produce huge amounts of excess heat. Turning it into electricity could play a key role in achieving a net-zero society.

The Sunnylands Statement sets a positive signal: World leaders gathered for COP28 must build off of it

The Sunnylands Statement has set a powerful signal for COP28, however, it also highlights that more must be done in Dubai to define what it means to achieve ‘net zero.’

E-fuels can play a huge role in Canada’s journey towards a net-zero future

E-fuels are materials that reliably and efficiently store energy until we need to use it and can readily be moved from place to place. They could be a major player in Canada’s green transition.

Oil and gas sector’s low compliance with methane regulations jeopardizes Canada’s net-zero goals

Regulating greenhouse gas emissions is an important part of Canada’s strategy to achieve net-zero emissions by 2050. However, a newly published study illustrates why enforcing regulation is key.

Forget net-zero: to halt global heating, aim for net-negative

New research suggests it will be next to impossible to limit global warming to safe levels without relying on technologies to directly remove carbon from the air.

Planting trees can help the climate, but only if we also stop burning fossil fuels

Planting trees and preventing deforestation can store carbon in nature, but the effect may only be temporary. If we also eliminate emissions from fossil fuels, even this temporary effect is important.

The climate crisis demands courage not optimism

Instead of asking about optimism, it’s time to ask what we as citizens are going to do about climate change.

What is a climate stress test? A sustainable finance expert explains

Regulators, banks and policy-makers use stress tests to uncover weak points in how financial institutions operate and identify changes that will help buffer them from harm.

Canada praised for climate leadership despite scathing watchdog report on climate-policy failures

As one of the few countries to have enshrined net-zero into law, Canada has earned praise for its climate leadership. Yet an independent report calls out its continued failures to reduce emissions.
