Companies touting their use of renewable energy may be overstating their contributions to the fight against climate change, new research suggests.
“There’s a big role for scrutiny of companies’ claims about use of renewables,” said Anders Bjorn, a researcher at Montreal’s Concordia University School of Management who just published a study in the journal Nature Climate Change.
The paper examines how businesses increasingly report on their efforts to reduce the amount of greenhouse gases they emit.
One of the common ways for companies to try and reduce their carbon footprint is to “buy” a certain amount of energy from a green producer. Although the power they consume still comes from the grid, the companies get a renewable energy certificate they can apply against their actual emissions.
The hope was that demand for those certificates would increase their value and encourage the growth of renewable power. But did it?
“In most cases, it has not happened,” Bjorn said.
Previous research has shown that the certificates add, at most, less than five per cent to the price of the power — not enough of a premium to drive investment and increase renewable generation.
That means buying the certificate has done little to promote the growth of renewable energy, Bjorn said. The details of who buys which kind of power shift, but the overall balance between renewable and fossil fuel generation doesn’t change.
“The certificate is not what caused the renewable energy to be produced. You are taking credit for something that would have happened anyway.”
Still, companies who buy the certificates claim full value for the reduced emissions.
Bjorn and his colleagues looked at 115 corporations around the world who have joined the Science Based Targets Initiative, sponsored by groups including the United Nations and the World Wide Fund for Nature. He found those corporations claimed to have reduced their emissions by an average of about 30 per cent between 2015 and 2019.
“If all emissions were reduced at that rate, we would meet our 1.5 degree Paris targets,” said Bjorn. “Everything looks good.”
But when the team dug into the numbers, they found that about two-thirds of those claimed reductions were from renewable certificates. When the certificates were taken out, the real-world emissions reductions from those companies was barely 10 per cent.
That’s well short of the pace needed to meet Paris Agreement goals, Bjorn said.
Bjorn said a better way to increase renewable energy generation is through the use of power purchase agreements — long-term contracts between green power generators and consumers that do provide the financial stability and income for growth.
“If you do it through power purchase agreements, there’s a lot of indication that it actually does lead to more renewables because of this long-term fixed price, which makes a difference on decisions on whether or not to build more renewables.”
Meanwhile, Bjorn urges people to view corporate claims of rapid emissions reductions with skepticism.
“When you look at all these companies that have reported emissions reductions, you would probably get the idea that total emissions from the grid are reducing really fast. That might not be the case.”

TORONTO – Ontario is pushing through several bills with little or no debate, which the government house leader says is due to a short legislative sitting.
The government has significantly reduced debate and committee time on the proposed law that would force municipalities to seek permission to install bike lanes when they would remove a car lane.
It also passed the fall economic statement that contains legislation to send out $200 cheques to taxpayers with reduced debating time.
The province tabled a bill Wednesday afternoon that would extend the per-vote subsidy program, which funnels money to political parties, until 2027.
That bill passed third reading Thursday morning with no debate and is awaiting royal assent.
Government House Leader Steve Clark did not answer a question about whether the province is speeding up passage of the bills in order to have an election in the spring, which Premier Doug Ford has not ruled out.
