Long the industry standard, lithium-ion batteries come with considerable drawbacks that limit their widescale adoption as the grid-energy storage medium of choice.

Two billion to subsidise green hydrogen sounds like a lot. But the world is racing ahead and we’re still at the starting line.
Environmental, social and governance investing, a form of responsible investing that aligns financial returns with positive environmental and social ones, has gained exponential popularity in recent years.

The criticisms faced by ESG projects are indicative of the growing polarization in the future profitability of the fossil fuel sector.

Canada has no choice but to adapt its energy sources and industries in a ‘just transition.’ If it doesn’t, the inevitable transition will be much more disruptive — and much less just.
Emissions from space heating and cooling in homes represent almost one-fifth of global greenhouse gas emissions.

Energy companies have marketed natural gas as cooks’ favorite for years because homes with gas hookups will also use it for space and water heating.

A different future will not be possible without reverence, respect, reciprocity and responsibility towards the Earth. On this issue, Indigenous Peoples have a lot to share.
Climate researchers stress that natural gas bridges can often lead to nowhere as the reliance on natural gas can lock countries into fossil fuels, crowd out low-carbon technologies and risk stranding assets.

Fossil fuel companies are winning the battle on how we talk about natural gas expansion by referring to it as a “bridge fuel” or an essential bridge to the net-zero energy system of the future.
Concrete is responsible for more greenhouse gas emissions than aviation.

Cement is responsible for more than 8% of global greenhouse gas emissions. Its emissions doubled over the past two decades, and demand is still rising fast.
The war in Ukraine will have major implications for energy and climate change, in Canada and the rest of the world, far into the future.

New relationships between energy, geopolitical security and climate change policy flowing from the invasion of Ukraine are beginning to emerge, and the implications could be enormous.
Some industries, including steel and cement, emit carbon dioxide as part of the manufacturing process, and could benefit from carbon capture technologies.

Carbon capture technologies have been labelled as a distraction. But as we enter the all-hands-on-deck phase of tackling climate change, they must not be ignored.

Canada has neglected to keep up with China’s climate politics, putting the future of the country’s fossil fuel exports at risk.
The consensus-based nature of the UN climate change summits means any single country with a significant fossil fuel interest can either weaken or sink an otherwise stronger multilateral agreement.

The recent climate conference in Glasgow, Scotland, shows that climate change deniers have shifted their tactics to thwart the efforts of countries to phase out fossil fuel use.
Phasing out fossil fuels means that today’s production is the peak, and that from here on out extraction and infrastructure must decline over time.

If Canada chooses to keep its oil in the ground, it doesn’t mean turning off the tap overnight. Skilled trades will be key to winding down the industry and building up new lines of work.
A coal mine in Alberta. Canada has adopted a carbon neutral target for 2050. It represents a major change Canada’s approach to reducing GHG emissions.

The goal of carbon neutrality changes everything. Canada can no longer limit itself to solutions that partially reduce emissions here and there. The chosen solution must be zero emissions.
Prime Minister Justin Trudeau is seeing nothing but blue skies ahead when it comes to his policies on climate change. But will the newly re-elected Liberal government follow through?

While the outcome of the 2021 federal election offered little in the way of change, it may have left Canada better positioned to make progress on reducing greenhouse gas emissions.

Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.
For more than 20 years, Canada has repeatedly missed its targets to reduce greenhouse gas emissions. It is the only G7 country whose emissions have increased since 2010.
