Aston Martin is at the centre of a climate lobbying controversy after a study co-commissioned by the company that cast doubt on the green credentials of electric vehicles was found to have been attributed to a PR company registered to the wife of a director at the luxury carmaker.
The study, which has since been widely debunked by experts, was presented as “groundbreaking” third-party research and appeared to show that electric cars would have to travel as far as 50,000 miles before matching the carbon footprint of a petrol model.
Thursday’s report was commissioned by companies including Aston Martin, Bosch, Honda and McLaren shortly after the UK prime minister, Boris Johnson, called for a ban on the sale of new fossil fuel vehicles from 2030, and presented as the work of Clarendon Communications.
But it can be revealed that the same companies that were credited with commissioning the study collaborated to write the report themselves, and the communications firm is a company registered under the name of Rebecca Stephens, who is the wife of Aston Martin’s government affairs director, James Stephens. The company was set up in February and registered to the address of a property jointly owned by the married couple.
The study was first reported in the Times, before the Daily Mail and the Daily Telegraph, among other news publications, followed suit.
Rebecca Stephens, a part-time NHS nurse, told the Guardian via email that the report attributed to Clarendon was “compiled” by the same companies that commissioned the study. She added that Clarendon was contracted by Bosch “to provide public affairs and stakeholder support” so its logo and contact details appear on the back of the report “for this purpose”.
A spokeswoman for Bosch said the company fully supported the report, “which has been drawn from independent, referenced data” and called for “greater transparency” on the carbon footprint of vehicles.
The report’s findings were based on studies undertaken by Polestar, an electric vehicle maker owned by Volvo, on the carbon impact of its Polestar 2 model. The company’s chief executive, Thomas Ingenlath, said it had left out key data points that would lower the emissions footprint of the vehicle by up to a third.
“Polestar 2 clearly has a lower carbon footprint than a comparable internal combustion engine vehicle when considering its whole life cycle, regardless of how it is charged,” he said. “Electric vehicles are the future and offer a route to carbon neutrality, something fossil-fuelled vehicles can never achieve.”
Concerns over the report were first raised by Michael Liebreich, the founder of Bloomberg’s clean energy research arm BNEF, in a Twitter thread that has become known within the industry as “Astongate”.
“We need to have a proper discussion about how we are going to get to net zero,” he said. “What we can’t have is the auto industry and fossil fuel incumbents twisting the discussion to their own advantage using sock-puppet PR companies and underhand tactics. The time for that is over.”
Independent experts including Auke Hoekstra, an authority on the emissions of electric vehicles (EVs), have refuted the findings of the report and warned that the data presented may have overstated the carbon footprint of EVs threefold by failing to account for a number of factors within the data.
Francis Ingham, director general of the Public Relations and Communications Association, said: “We have a duty to fight misinformation, not purvey it. PR agencies should be fully transparent about who they represent. Failure to disclose client relationships damages trust in our industry and lends credence to misleading perceptions of PR as a sinister practice.”
The Labour MP Matt Western, who wrote the foreword for the report, said he had agreed to be involved in the project “to push this agenda forward, rather than the opposite”. “I am disappointed that the report has since been used to push an anti-electrification line in the media,” he said. “I was not aware of any link between the PR firm involved and Aston Martin.”
Aston Martin confirmed that it “contributed” to the report before the government’s decision on fossil fuel vehicles “to emphasise how best to achieve the government’s stated aim”.
The Warwickshire-based carmaker has been slow to adapt to electrification, and does not yet manufacture any electric models. Instead, the company handed a fifth of its equity to Mercedes Benz in exchange for access to the latter’s hybrid and electric vehicle technology in an effort to adjust to a low-carbon future.
The spokesman said Aston Martin engaged with the government regularly on its plans to cut carbon emissions from the UK’s road transport “to ensure the opportunities and challenges are both understood and addressed”.
