As the longest United Nations climate talks on record end with a compromise in Madrid, new research from the University of Waterloo has found that higher emission reduction pledges consistent with the Paris Climate Agreement are needed to preserve ski tourism in Eastern Canada and the U.S.

"The future of our multi-billion-dollar ski industry depends on our climate choices. To preserve it and the thousands of jobs it provides requires us to achieve a low carbon transition," says Daniel Scott, a and professor and executive director of Waterloo's Interdisciplinary Centre on Climate Change (IC3). "If we do not achieve the Paris Agreement, in the latter half of the century, only high-elevation areas of the Vermont and New Hampshire and select ski areas in Qu茅bec will be able to maintain a 100-day season and open regularly over the Christmas-New Year holiday."

Climate change will have an important influence on the ski tourism markets in the US Northeast, Quebec and Ontario, but Scott's research, in collaboration with colleagues from the University of Innsbruck in Austria, and the School of Sports at the Sport University in Beijing, demonstrates the starkly different outcomes of low and high emission futures.

A successful Paris Agreement would limit ski season losses across the region to 12-13 percent in mid-century and only 13-18 percent by late century. In stark contrast, in a high emission future, ski seasons are eventually cut in half at most of the 117 ski areas included in the study, with only 6 percent of Ontario ski areas and 30 percent in the US Northeast still able to remain economically viable as early as mid-century.

The study also found that adaptation to a changing climate is as important as emission reductions to a positive future for the industry. Snowmaking needs to double in a low emission future but increase as much as 300-500 percent if high emissions occur.

"Snowmaking is even more essential to the ski industry in a warmer world, and it must be made carbon neutral," says Scott. "Ski area operators need to engage with community-level climate action plans and be strong advocates for the climate policies that are so essential to their future."

"This research shows the ski industry in North America is at a major crossroads," says David Erb, executive director of Protect Our Winters Canada. "If we can stay on track with our commitments to the Paris Climate Agreement, the industry can adapt and continue to operate, but if we don't, the future of the industry is very much in doubt. Essentially, the future of winter is in our hands."

Scott's study appears in the Journal of Sustainable Tourism.
