Summary

  • After leaving cabinet late last year, former environment minister Steven Guilbeault will vacate his seat in Parliament altogether this summer.
  • He sees a fundamental difference in his approach to addressing climate change and that of Prime Minister Mark Carney.
  • Despite his exit, Guilbeault says he made great strides during his time in government and encourages young people to consider politics.

Steven Guilbeault says if he were asked again to leave activism for politics, “I would do it in a heartbeat.”

As he prepares to resign his seat, the former Liberal environment minister has been called the most ambitious the country has ever had. He believes his time in government was worth it — that, by being on the inside, one can achieve great things. His message to young people interested in climate action: consider the political arena.

Still, Guilbeault leaves as several major environmental policies he had a hand in developing are being rolled back or brushed aside by the government of Prime Minister Mark Carney. Guilbeault believes the prime minister thinks global markets will take care of things largely on their own. He disagrees.

Last week, two former members of Canada’s legislated advisory body on climate said Carney needs to be honest about how his policies have made the promise to achieve net-zero emissions by 2050 impossible. Guilbeault says the government is now facing two choices: keep its federal net-zero law in place and likely get sued by stakeholders for violating it, or repeal it and send a “powerful message” about how the prime minister sees the world.

Guilbeault spoke to The Narwhal for more than half an hour by phone on June 15.

This conversation has been edited for length and clarity.

I want to start with an interview you gave in 2022 in The Guardian. You said, ‘I came into politics so I could continue to be an activist.’ In your recent speech in Parliament you said, ‘I fully intend to keep fighting.’ So if you needed to go in to be an activist, and now you’re coming out to be an activist, where does that leave things — is it better to be on the inside or the outside?

I think we need people both on the outside and on the inside. I would like to think that I have shown that by being on the inside, you can achieve things, you can set goals for yourself or as a party — like we, for the first time in our history, under the previous administration, have shown that through public policies, we can fight pollution and grow the economy. This has never been done before in the history of our country. 

We’ve shown that we can do great things when it comes to conservation, to improving environmental rights issues and environmental justice issues, including the right to a healthy environment in The Canadian Environmental Protection Act. Some of the work we have done using emergency orders, namely in Sarnia, Ont., with Aamjiwnaang First Nation, what we did on nature in 2022 at the United Nations Convention on Biological Diversity conference in Montreal — I think it is absolutely possible to be an activist inside.

My decision to leave politics is that I feel that, certainly when it comes to climate change … I can no longer continue to have an impact. That’s my own personal assessment, and obviously different people will come to different conclusions. But I can no longer have an impact inside, and it’s time for me to go back on the outside.

People in the climate space have expressed a sense of betrayal with Prime Minister Mark Carney on climate and the environment. They say, ‘What happened to the UN climate guy?’ and ‘What happened to the guy who wrote the book on values?’ Is that a feeling you share?

I’m not sure I would put it in those words. But if you look at the work he did with the Glasgow Financial Alliance for Net Zero, it was largely based on voluntary commitments by companies, investors and financial institutions. There was really no transparency or accountability. I’m not saying it has no value, it certainly has value. We’re seeing how, globally right now, the markets are playing a really important role. Renewables are driving two times more investment than fossil fuels are, globally. One in four cars sold globally was an electric vehicle — not Europe, not Sweden or Norway, but globally. 

I could be wrong about this, but I think where the prime minister and I differ in terms of our views of what needs to be done on climate change, is that I have come to the conclusion that he thinks that the markets are going to do it. And that governments don’t have an important role to play, if only to put in place measures to attract investors and tax credits. 

I think we’re going to make some progress in Canada on taxonomy and disclosure, because the prime minister sees this as an important element to attract investment for decarbonization. But I don’t think he sees an important role for public policy, for regulations. I think we need markets to achieve what we want to achieve, but markets alone won’t get us there.

I think that’s perhaps something I had not understood before — and I suspect I’m not the only one — about his vision for change. I guess you could call it his theory of change, when it comes to fighting climate change.

It took several years for environment and climate policies to be dreamed up, consulted on, put into legislation or regulations and enacted. Relatively speaking, it’s been lightspeed to tear many of them down again over the past year. Why haven’t they proved more durable?

Well, it’s always easier to destroy than it is to build. That’s true of regulations, it’s unfortunately true of many things. [That’s] number one.

Number two: many of these things, despite what has been said publicly, are still in force. The clean electricity regulations are still in place. Many of the changes we said we would make on methane [emission reductions], the regulations that apply right now in Canada, are still the federal methane regulations that have been approved. So the [methane allowances] in the agreement with Alberta, they will need to go through the process of making regulatory changes, which is more complicated than switching something on and off.

But you’re right, by the looks of it, this is where we’re heading. And yes, you’re right, it was long and painstakingly difficult at times to put these things in place. But that’s the price to pay to live in a democracy. A duly elected government in a democracy can change things that previous governments have done, and that’s something we have to accept.

Do you think the days of Canada’s net-zero law — committing us to negating greenhouse gas emissions by 2050 and setting increasingly stringent targets to get there — are numbered?

I think a lot of people don’t realize that our 2030 and 2035 targets are not voluntary targets in Canada, they’re legally binding, and there will be consequences if Canada doesn’t meet those targets. It’s going to become painfully clear in the very near future that we won’t be able to achieve those targets, regardless of what the government continues to say. I mean, you can be committed to those targets and not have any chance of meeting them, so it’s a bit disingenuous to say that we are committed. 

I think they’re going to be faced with two difficult choices: either they keep the climate accountability act in place, and then what is likely going to happen is that the federal government is going to get sued by different stakeholders for not abiding by federal law. Or they have to repeal it, which would send a pretty powerful message to Canadians about how little this government is concerned with climate change.

If they did decide to repeal the law, to what would you compare that?

Well, with the United States, we would become one of a handful of countries in the world to basically turn our back on the Paris Agreement. That’s in effect what it would mean. And I suspect that you know it’s true that, right now, when you look at public opinion research, Canadians care more about other things than they care about climate, but they still care about climate change.

You talked about the prime minister putting faith in a market-based solution to climate action. Do you think that idea extends to his position on international agreements like the Paris Agreement, to keep global warming below 2 degrees Celsius?

That’s a good question. I mean, it is interesting that when you look at the spring economic statement, Canada renewed its climate finance commitment under the Paris Agreement, [committing billions toward climate change adaptation and climate-related businesses in “vulnerable countries”]. That is one area where Canada is still doing pretty good. We’ve slightly increased our climate finance package for the first time ever, we’ve set a goal of mobilizing funds with the private sector. The UK has reduced their climate fund, France has, the United States has. From that context, the fact that Canada would slightly increase theirs is, in and of itself, a small victory. And we’ll take all the victories we can take right now, right? 

The honest answer to your question right now is, I don’t know what his views are on that. But we may infer from our climate finance commitment that it is still something that’s important to him.

At the environment committee recently, Catherine Abreu and Simon Donner said the government didn’t want to hear from the net-zero advisory body. Does the Carney government not listen to experts?

We can still see that scientists and experts have a voice, and they can still express their opinion, which was a big difference from the Stephen Harper years.

I do think that there is a negative bias by this government towards regulations, and regulations are perceived by many as being some form of impediment to free markets and impeding investment. I would disagree with that analysis. You go back to 2024, for example, Canada came in second in the G20 for foreign direct investment in comparison to the size of our economy, while we were full-speed ahead deploying our climate change plan. So it seems that foreign investors didn’t have a problem with coming to Canada to invest, despite the fact that we had an aggressive plan to fight climate change. This idea that these two things are in opposition to one another doesn’t seem to stand the test of facts.

When you say the government holds a negative bias, are you talking about Prime Minister Carney specifically, or members of his cabinet, or senior officials or all of the above?

From what I’ve been able to observe, I think it’s the case that there are many people who feel this way, some on the political side, some on the bureaucracy side. I’m not saying everyone agrees with that idea, but certainly around the prime minister there are many, which is why we’re seeing such a push towards deregulation, because many people in positions of influence are pushing for this agenda. 

Unfortunately, we’re putting at risk the health of Canadians with some of the changes that are being proposed — whether it’s on impact assessment reform or pesticides management. I think we will likely quickly come to the conclusion that we’re doing so at a greater risk for Canadians.

Is there someone in particular you’re thinking of around the prime minister who is pushing for that deregulation?

I think it’s larger than one or two people. At least with people who have important portfolios on the economic side, I think it is a general perception.

What’s your message to young people now, who are just being introduced to the climate movement? They see you deciding to quit politics, talking about the backsliding that’s going on. They see you talking about getting into it in the 1990s. Maybe they’re a bit skeptical that there is the same sort of urgency and hope as there was in that decade. What’s your message to them?

My first message would be that we need good people in politics. I was there for almost seven years. In working with many others, I was able to achieve many things. There’s no way I could have helped to convince 196 countries to protect 30 per cent of the planet in Montreal in 2022 if I had stayed at Équiterre. Just not possible. 

The single-use plastics ban. My first bill in parliament was the creation of the National Day for Truth and Reconciliation. I was talking about the inclusion of a right to a healthy environment in the Canadian Environmental Protection Act, new regulations on [toxic effluent from] the oilsands — we were able to do a lot of things. If I have to do it all over again, I would do it in a heartbeat.

I have colleagues who have, despite what is happening, decided to stay and fight the good fight from the inside. I think it’s a highly personal call. 

I was coming to the conclusion that by staying inside, I was becoming a tool to justify some of the things the government is doing, which I find to be unjustifiable. I was hearing from some people, ‘Well, if Steven is still there, then it’s probably not so bad.’ That’s one of the reasons I feel that it was time for me to leave. 

But what I would tell those young folks is, go into politics. If this is something you’re interested in, it’s an incredibly important arena to push for change.

What’s next for you?

I have not figured that out. I’m going with [the Students on Ice Foundation] in the Arctic this summer, 40 young Canadians, for almost two weeks. After that I’m going to start looking at what my options are. But I know that I’m going to keep working on issues of climate change and sustainability and nature, one way or the other.
