A bipartisan consensus on climate change? The U.K. suggests it's not a pipe dream

From this side of the Atlantic, the new greenhouse gas emissions target recently adopted by the United Kingdom was notable not only for its ambitionbut for the fact that the goal was adopted by a Conservative government.

The U.K. is now aiming to reduce emissions by 78 per cent below 1990 levels by 2035.Of course, setting a goal is not the same as implementing policies to achieve it. And it would be a mistake to assume that the debate over climate policy in the United Kingdom is perfectly settled and rational.

But the U.K.'sexampleshould suggestthat the politics of climate change don't have to be as polarized as they have been so often in Canadaover the past 15 yearsthat it is possible to get to a point where the idea of safeguarding the future of life on this planet is not the subject of such pitched debate.

Last year, the Pew Research Center released polling that measured the differences in levels of concern about climate change expressed bythose on the political left and those on the right in 14 countries.

In Canada, the divide was 29 percentage points 82 per cent of those on the left said climate change was a major threat to their country, compared to 53 per cent on the right. Among the countries surveyed, that was the third-highest split.

A difference in political culture

The split in the United Kingdomwas only slightlysmaller, at 24 points. But on the U.K.'s political right, concern was notably higher in the Pew survey62 per cent said climate change was a major threat.

Alan Andrewsworked for eight years in the United Kingdomwith Client Earth, an environmentallaw charity, before becoming climate director for EcoJustice in Canada. He noted that the U.K.'s Conservative Party has some history with climate change thanks to former prime minister Margaret Thatcher.

Thatcher's legacy on environmental issues is perhaps debatable. But during what has been described as her "green period," she did speak to the emerging threat. Andrews pointedto her remarks toa United Nations conferencein 1990: "The danger of global warming is as yet unseen, but real enough for us to make changes and sacrifices, so that we do not live at the expense of future generations."

Andrews also pointedto a cross-party consensus that emerged in the U.K. a little over a decade ago.

In 2006, Tony Blair's Labour government released a landmark report on the economics of climate change, authored by British economist Nicholas Stern. Around the same time, Conservative leader David Cameron was looking to broaden his party's appeal after a series of election defeats. Heseized on the environment as a way to do that "Vote Blue, Go Green" was the slogan.

In 2008, Blair's government passed the Climate Change Act with cross-party support. That legislation put the U.K.'s emissions targets into law and created the Climate Change Committee to provide expert oversight and advice.

Taking the politics out of climate policy

"The Climate Change Act, I think, really cemented that consensus ... such that it has held for nearly 15 years through some pretty tumultuous times in British politics," Andrews said in a recentinterview.

"It deliberately attempts to depoliticize climate change so that it isn't used as a wedge issue like you see it being used in Canada. It sets up the Climate Change Committee as a fiercely independent and very well resourced institution, which provides very well-researched, evidence-based policy solutions, does a great job of communicating about not just the threat of climate change, but the opportunities and the solutions that are on the table. And it holds government's feet to the fire."

In Canada, it's tempting to imagine that the Liberal government's own climate change accountability bill could end up having a similar effect with a new net-zero advisory panel and the federally funded Institute for Climate Choicesserving a functionsimilar to that of the U.K. committee. It's unclear, however, whether Conservative MPs, who have objected to the membership of the advisory panel, will vote in favour of that legislation.

When climate change became a wedge issue

If they were so inclined, Canada's Conservatives could claim an environmental heritage of their own. Around the same time Thatcher was going through her"green period", Brian Mulroney brokered a deal with the United States to fight acid rain and his government hosted the Toronto Conference on the Changing Atmosphere, one of the first major international summits to deal with global warming.

But just as the major parties in the U.K. were converging on climate policy, Canada's parties were polarizing. When Stephen Harper's Conservative government chose to loudly attack the Liberal Party's call for a carbon tax in 2008, it created aschism thathas defined the climate debate in Canada for most of the past 13 years.

Erin O'Toole's shy embrace of carbonpricing this spring was the Conservative Party's first step back toward the progressive consensus on the need for climate action.

Andrewsagreed that there are at least two other factors thatmight explain the difference between the U.K. and Canada.

First, there is the potential influence of the U.K.'s proximity to the climate-conscious countries of Europe and the fact that Canada's neighbour is the highly polarized United States of America. In the U.S., the climate split between left and right is 59 points, by far the highest mark of the 14 countries polled by Pew. In France, the split is ten points.

Second, there is the significance of oil and gas. In Canada, the oil and gas industry accounts for five per cent of national GDP. In the U.K., it's one per cent.

In Canada, that emissions-intensive industry is regionally centredin two provinces, Alberta and Saskatchewan, that typically vote Conservative. Accounting for that industry is pivotal to meeting Canada's climate goals, but there's a difficult political history and a highly politicized debate about oil development to overcome.

Still, it should be noted that the current era of increased climate ambition really began in 2015 when there was a moment of alignment between the government in Alberta (then led by the NDP's Rachel Notley) and the federal government.

Perhaps the example of the United Kingdom andofsomeother countries where the political divide is even smaller tells us that the debate over climate action doesn't need to be as divisive as it has been in Canada for more than a decade now.

Some amount of disagreement will always exist. But the next step in Canadais to get to a place where the debate is less about whether this country should significantly reduce its emissions and more about how. The example of other countries tells us that'snot a completely unreasonable dream.
