Good afternoon, and welcome to Globe Climate, a newsletter about climate change, environment and resources in Canada.
After two decades doing climate work for NGOs, Steven Guilbeault took a leap into government. This past week, he announced his resignation from politics, and a return to fighting for the environment outside of Parliament. More on that today.
First, let’s catch you up on other news.

Steven Guilbeault says goodbye
For this week’s deeper dive, a closer look at a high-profile climate departure from politics.
In today’s letters to the editor, Tom Perry from Vancouver wrote: “In the Liberal Party or the government, who will now advocate for Planet Earth?”
Former Liberal cabinet minister Steven Guilbeault announced his resignation from politics last week, saying he wants to keep up his fight against climate change in other ways. That announcement has put Prime Minister Mark Carney on the defensive once again about the Liberals’ climate change policy.

For example, we reported that climate and energy experts are concerned by the fine print in Ottawa’s pipeline deal with Alberta, and the carbon-pricing system underpinning it. Carney insists that the country’s new climate plan will withstand the test of time amid more demands for changes from the oil and gas sector.
Guilbeault, a career environmentalist, played a key role in many of the previous Liberal government’s climate initiatives now being watered down or straight up reversed by the current government. He plans to resign from his seat later this summer. He quit Carney’s cabinet at the end of last year over the same Ottawa-Alberta energy accord, and issued a scathing letter laying out why he thinks the deal undercuts environmental protections.
In an earlier statement, Carney said the government remains committed to climate action. “We are advancing these missions with the same determination, a new spirit of partnership, and a renewed focus on results.”
Our resident food and farming reporter Kate Helmore attended the opening of Toronto Climate Week this morning, curious about what the Prime Minister’s wife had to say about our changing environment and how Ottawa is reframing the climate file. (Interesting factoid: Diana Fox Carney has a master’s degree in Agricultural Economics). The following quote sums it up:
“Third moral arguments do not get us to where we need to be in a more volatile and uncertain world, where affordability and now security are the dominant concerns. Climate action often falls off or fails to reach the list of priorities. What’s important is to meet people and pools of money where they are, not where we wish they were,” she said.
This opinion is in line with the Prime Minister, who said a gracious goodbye to Guilbeault, mentioning that he has “always been guided by his convictions and driven by his pursuit of a stronger, more inclusive and more sustainable future.”
Guilbeault also said a restrained goodbye to Ottawa, as he spoke from the floor of the House of Commons. He didn’t speak on Carney’s policies, but it was easy to read between the lines.
“The fight for our planet is the struggle of our generation, and I fully intend to keep fighting,” he said.

Opinion and analysis
Canada prices carbon far below the damage it causes
We are free to debate what climate policy is politically achievable today. We are not free to decide whether younger generations will pay the price when political convenience collides with planetary reality.
— Dr. Paul Kershaw, policy professor at UBC and founder of Generation Squeeze
Ottawa-Alberta deal is the best outcome climate advocates could have hoped for
I understand why climate advocates are disappointed, but I’m cautiously optimistic that this deal can produce real gains for Canadian climate action over the long term.
— Michael Bernstein, president and chief executive of Clean Prosperity
Whither the future of the ESG movement?
It turns out that governments have been unwilling, rather than unable, to weigh in on sustainability concerns.
— Edward Waitzer, senior fellow at the C.D. Howe Institute

Purpose Investments did not incorporate ESG factors as much as claimed, OSC alleges in hearing
For years, Purpose Investments Inc. did not incorporate environmental, social and governance factors into its investment decisions anywhere near the extent that the company and its founder had repeatedly asserted, the Ontario Securities Commission alleged in a hearing last week.
The company’s high-profile greenwashing case is before the Capital Markets Tribunal, an independent division of the OSC. It is expected to span several months, with multiple witnesses expected to testify, before concluding in September. Tuesday was the first day of hearings.
