Canada’s Election Goes Light on Climate Policy

Canada’s Election Goes Light on Climate Policy

Current conditions: Lisbon and “most of Spain” are without power due to a massive blackoutDubai residents are being told to limit outdoor activity today as temperatures could hit 108 degrees FahrenheitMonday will be “one of the most active days of severe weather so far this season” in the U.S., with meteorologists issuing a rare “high risk” warning for intense storms and destructive tornadoes across the Upper Midwest.

THE TOP FIVE

1. Canada’s election, light on climate, culminates today

It’s Election Day in Canada, where Liberal Party leader Mark Carney holds a modest lead against the Conservative Party’s Pierre Poilievre — a “stunning reversal” from late last year, when Conservatives had a 20-point lead in the national polls. But that was before President Trump’s tariffs and comments about annexing the country.

The election has been a stunning reversal in other ways, as well: In 2021, “the environment topped the list of voter concerns,” the BBC notes, and “there was a consensus between the two major parties that Canada should rapidly transition to a green economy.” But climate change has not been a central talking point of the 2025 campaigns, even for Carney, a former special envoy on climate action and finance to the United Nations.

Instead, Carney cut the country’s carbon tax on his first day as prime minister following Justin Trudeau’s resignation, and he has vowed to make Canada a “leading energy superpower” by expanding oil and gas production along with renewable energy and carbon capture and storage technology. Poilievre, a proponent of significantly expanding the nation’s oil and gas industries, has argued that “technology, not taxes, is the best way to fight climate change and protect our environment.” The winner is expected to be announced Monday night or early Tuesday morning.

2. Clean energy manufacturing investments declined in Q1 for the first time since the passage of the IRA

Clean energy manufacturing fell in the first quarter of 2025, marking “the first decline since the Inflation Reduction Act was signed in 2022,” Barron’s writes based on a new report by the Massachusetts Institute of Technology and the Rhodium Group. While clean manufacturing has more than tripled, from $2.5 billion at the end of 2022 to $14 billion in the first quarter of 2025, the surge has been driven primarily by the electric vehicle supply chain. In the first three months of the year, six manufacturing projects worth $6.9 billion in investment were canceled, representing “the highest value of cancellations on record,” while $2.1 billion in earlier-stage investments were also canceled. “Among the companies that changed their plans were T1 Energy, formerly known as Freyr Battery; Kore Power; and the electric-vehicle start-ups Nikola and Canoo,” Barron’s notes, with the report crediting some of the turbulence to the fact that the sector “faces rising headwinds from tariff escalations, an uncertain federal policy outlook, and macroeconomic pressures.”

3. Trump admin pressures IEA to drop focus on net zero

The Trump administration is pressuring the International Energy Agency to “cease its work promoting the global shift to clean power and net-zero carbon emissions,” Politico reports. During the organization’s conference in London last week, attendees largely championed “an exciting vision of energy security and abundance from cheap, homegrown low-carbon power,” in the words of the UK’s Energy Secretary Ed Miliband. The U.S. acting assistant secretary of energy for international affairs, Tommy Joyce, took a different view, however, bashing net-zero policies that, he said, “harm human lives.”

Republicans have been calling for years for the U.S. to “come up with a strategy to replace leadership at the IEA,” and Treasury Secretary Scott Bessent and Vice President JD Vance have pushed similar “energy dominance” narratives in their own recent international meetings. But despite what a European official described to Politico as the U.S.’s evident intention to “weaken or disable the IEA unless they’re working on our values,” a French official told reporters that “decarbonization is both an objective and a tool” of energy security and “we have no fear that the IEA will change its position.”

4. BYD doubled its net profit in Q1

Chinese electric vehicle manufacturer BYD doubled its net profit since last year, from 4.6 billion yuan to 9.2 billion yuan (about $1.3 billion), the company reported in its first-quarter earnings on Friday. The automaker also announced that its revenue increased 36% year-over-year, with total sales of EVs and hybrids rising 60% to over a million units. The earnings stand in stark contrast to Tesla’s Q1 results, which saw profits fall 71% over the first three months of the year. BYD overtook Tesla as the world’s top EV seller in 2024, and The Wall Street Journal notes that it “appears relatively insulated from the U.S. tariffs on the auto sector, having long prioritized other international markets.” You can learn more about how BYD became “the most important car company most Americans have still never heard of” by listening to this episode of Heatmap’s Shift Key podcast.

5. xAI is ‘perpetuating environmental racism,’ Memphis residents say

More than 200 people gathered in South Memphis on Friday night to voice their concerns about the use of gas turbines to power the supercomputer facility of Elon Musk’s artificial intelligence company xAI, the Memphis Commercial Appeal reports. “We deserve clean air, and our lungs are not for sale to xAI or Elon Musk,” Democratic state Representative Justin J. Pearson said at the event.

Earlier this month, the Southern Environmental Law Center announced that it had obtained aerial images showing that the Memphis xAI facility was using at least 35 portable methane gas turbines without air permits to power its supercomputer — despite Memphis Mayor Paul Young’s claims that “only 15” were turned on while the permitting was pending. KeShaun Pearson, the president of Memphis Community Against Pollution, slammed xAI over “perpetuating environmental racism” with the illegal generators, since methane emissions have been linked to serious health problems like asthma and certain cancers. The public comment period for the plant’s operations permit for 15 gas turbines closes on April 30.

The three-year-old activist group Just Stop Oil held its final protest in London this weekend, claiming it has achieved its goal of halting the United Kingdom’s extraction of oil and gas following the Labour Party’s suspension of new exploration licenses in the North Sea in March.

Exclusive: Marathon Fusion Achieves Reactor Fuel Breakthrough

The seed-stage startup is eyeing a Series A after successfully enriching lithium and hydrogen isotopes.

While most coverage of the buzzy fusion energy industry — including my own — tends to focus on the startups promising to build commercial reactors within the next decade, a whole host of supporting industries will also need to mature in order to make that long-held scientific dream a reality. Isotope production is one of the biggest. No matter a company’s technical approach to fusion, it likely demands hydrogen and lithium isotopes — the former to fuel reactors, and the latter to breed more of that fuel.

That’s where Marathon Fusion comes in. The San Francisco-based seed-stage startup is developing isotope separation technology for two key purposes: recycling tritium — an extremely rare hydrogen isotope — from reactor exhaust so it can be reused as fusion fuel, and enriching lithium-6, which is needed to breed new tritium. On Thursday, the company announced that it succeeded in using its plasma centrifuge technology to enrich lithium-6 and hydrogen isotopes in the lab. (It can’t yet test the tech on actual tritium, which is expensive, radioactive, and tightly regulated by the Nuclear Regulatory Commission, so Marathon is validating its separation physics using the non-radioactive proxies deuterium and protium.) Marathon now plans to raise a Series A based on the results.

The Case for Restoring the Wind and Solar Tax Credits

Rob talks with Amanda Levin, head of climate science and policy at the Natural Resources Defense Council, about why we shouldn’t give up on renewable subsidies just yet.

Two years ago, Donald Trump made an outlandish campaign promise: He would cut Americans’ power bills in half.

It was a ridiculous, impossible pledge — but even so, the affordability problem didn’t need to get this bad. A new report, out this week from the Natural Resources Defense Council, looks at the economic, environmental, and public health costs of Trump’s regulatory and legislative clean energy policies, including his rollback of the wind and solar tax credits.
