Research on Chinese dyeing industry offers lessons for Canada's carbon pricing
A study of Chinese textile exporters shows how a firm's ability to adapt shapes its response to environmental rules, a lesson for Canadian industry under carbon pricing.
The federal government lowered the planned trajectory for Canada's industrial carbon price in May, a move that highlights a central tension in environmental policy.
Under the revised schedule, the headline industrial carbon price stays at $95 a tonne this year and reaches $115 by 2030, well below the $170 previously scheduled for that year.
Industry groups welcomed the lower trajectory, saying it would reduce costs and give producers more time to adapt. Environmental groups criticized it, arguing that a lower price would weaken the incentive to reduce emissions.

"The disagreement reflects a familiar concern about environmental regulation: higher compliance costs can make domestic firms less competitive, particularly when producers elsewhere face less stringent environmental standards," wrote Longzhou Wang, an assistant lecturer at the University of Alberta's Alberta School of Business, in an analysis for The Conversation.
Wang's research on Chinese textile exporters suggests the level of an environmental requirement alone does not determine how firms respond.
"Whether firms have the capacity and opportunity to adjust to the requirement matters, too," Wang wrote.
He studied how firms responded to a tightening of wastewater standards around Lake Tai in Jiangsu province in 2005. The new rule cut the permitted concentration of chemical oxygen demand from 180 milligrams per litre to 100.
By comparing firms subject to the new rule with similar firms in neighbouring provinces that were not, Wang found the first rule prompted the regulated exporters to adapt.
The quality of what they sold abroad improved by 4.8 per cent relative to their unregulated neighbours.
"They installed more advanced equipment, increased spending on innovation, shifted their product mix towards higher-quality goods and improved their productivity," Wang wrote. "Their costs increased and employment fell, while the quality of their exports improved."
A second, stricter round of regulations followed a severe algal bloom in 2007. This time, export quality fell by 9.3 per cent.
"The stricter standard changed how much firms could produce, and it hit the highest-quality producers hardest," Wang wrote. "Firms producing the highest-quality goods cut production most sharply because meeting the tighter standard used up capacity they had spent years building."
The two episodes suggest that the effect of an environmental requirement depends not only on how stringent it is, but also on whether firms have a way to meet it.
Wang noted important limits to applying the research directly to Canada, as it involved a different country, pollutant and industry two decades ago.
"Chinese dyeing mills are not Canadian steel plants. My results cannot tell Ottawa what the carbon price should be," he wrote.
But the research shows what can happen when firms face increasingly demanding environmental requirements.
"For Canadian companies, the effect of the carbon price will depend partly on how easily they can adapt," Wang wrote. "Some industries have commercially available technologies for cutting emissions, while others face more expensive or technically difficult changes."
A large integrated producer may have more capacity to finance new equipment than a smaller regional company, and the compliance timeline will matter, he added.
"A carbon price can set the incentive to reduce emissions, but it cannot determine whether the technology, financing and time needed to respond are available," Wang wrote.
The stakes for Canadian exporters are rising with new international rules.
The European Union's carbon border adjustment mechanism entered its definitive phase on Jan. 1, 2026, and Britain's version is scheduled to begin on Jan. 1, 2027.
"For Canadian exporters in those sectors and for a country looking for customers outside the United States, reducing emissions is becoming a condition of market access rather than a domestic compliance cost," Wang wrote.
Canada has now settled its carbon pricing number through 2030.
"Whether that price leads Canadian firms to invest, adapt or scale back will depend partly on what options they have for meeting it," Wang concluded.
