According to the Trudeau government’s emissions reduction plan, “putting a price on pollution is widely recognized as the most efficient means to reduce greenhouse gas emissions.” Fair enough, but a reasonable person might wonder why the same politicians who insist a price mechanism (i.e. carbon tax) is the most efficient policy recently announced relatively inefficient measures such “sustainable investment guidelines” and “mandatory climate disclosures” for large private companies.

The government claims that imposing mandatory climate disclosures will “attract more private capital into Canada’s largest corporations and ensure Canadian businesses can continue to effectively compete as the world races towards net-zero.” That is nonsense. How would politicians Ottawa know better than businessowners about how their businesses should attract capital? If making climate disclosures were a good way to help businesses attract capital, the businesses that want to attract capital would make such disclosures voluntarily. There would be no need for a government mandate.

The government has not yet launched the regulatory process for the climate disclosures, so we don’t know exactly how onerous it will be, but one thing is for sure—the disclosures will be expensive and unnecessary, imposing useless costs onto businesses and investors without any measurable benefit, further discouraging investment in Canada. Again, if the disclosures were useful and worthwhile to investors, businesses seeking to attract investment would make them voluntarily.

Even the government’s own announcement casts doubt that increasing business investment is the likely outcome of mandatory climate disclosures. While the government says it’s “sending a clear signal to corporate boards and shareholders, at home and around the world, that Canada is their trusted partner for putting private capital to work in the race to net-zero,” most investors are not looking to put private capital to work to combat climate change. Most investors want to put their capital to work to earn a good financial return, after adjusting for the risk of the investment.

This latest announcement should come as no surprise. The Trudeau government has demonstrated consistently that its policies—including higher capital gains taxes and a hostile regulatory environment—are entirely at odds with what investors want to see. Corporate head offices are fleeing Canada and business investment has declined significantly since the Trudeau Liberals came to power. Capital per worker in Canada is declining due to weak business investment since 2015, and new capital per-Canadian worker in 2024 is barely half of what it is in the United States.

It's also fair to ask, in the face of these onerous polices—where are the environmental benefits? The government says its climate disclosures are needed for Canada to progress to net-zero emissions and “uphold the Paris climate target of limiting global warming to 1.5°C above pre-industrial levels,” but its net-zero targets are neither feasible nor realistic and the economics literature does not support the 1.5 degrees target.

Finally, when announcing the new climate disclosures, Trudeau Environment Minister Steven Guilbeault said they are an important stepping stone to a cleaner economy, which is a “major economic opportunity.” Yet even the Canada Energy Regulator (a federal agency) projects net-zero policies would reduce real GDP per capita, increase inflation of consumer prices and reduce residential space (in other words, reduce living standards).

A major economic opportunity that will increase business investment? Surely not—mandatory climate disclosures will only further reduce our standard of living and impose useless costs onto business and investors, with the sure effect of reducing investment.
