A stand in the COP28 "startup village" has proved the arena to gain high level access and even clinch deals on the sidelines of UN climate talks that are striving for an agreement as countries argue over the future use of fossil fuels.

Four-month-old British company Clean Air By Resysten is among the many that have found a ticket to the climate talks is the fast-track way to an executive meeting.

After receiving no response to an emailed pitch to Dubai's DP World, Clean Air by Resysten received an executive from the state-owned ports giant at its stand.

The executive agreed to a demonstration of the company's spray-on surface coating that breaks down air pollutants and repels dirt to treat its solar panel arrays.

Resysten said it has also found prospective clients from Britain and Saudi Arabia. DP World had no immediate comment.

"I expect the pipeline coming out of COP at approximately $5 million, which is incredible," London-based Will Tyler, a director at Clean Air by Resysten, said. The company has yet to agree any contracts at the talks.

Among those representing the sectors hardest to decarbonize, Hamburg-based entrepreneur Thomas Demmel, who runs a concrete business Bton Holding GmbH, said he had received unprecedented access.

"We have gained reach within this conference that was completely beyond our expectations; private equity, banks, massive project developers, construction companies, concrete and cement companies," Demmel said, adding that he also unexpectedly met Bill Gates when he was walking by.

Demmel said he expected his attendance at COP28 to double the company's value based on the business leads so far.

Greener business?

Some campaigners saw a chance for greener business, while remaining wary.

"While their engagement is essential given the scale of the challenge, their burgeoning presence at these conferences often serves more as a distraction than a catalyst for effective policy-making," said Harjeet Singh, head of global political strategy at nonprofit Climate Action Network International.

Nigel Topping, who worked on that launch and advises the UAE official responsible for connecting government with non-state actors, said it was important to include the people with the "money and resources"

"Not all businesses may try and slow down climate policies, but definitely those in polluting sectors do."

The United Nations has also encouraged business participation at its annual climate summits and in 2020 launched the Race to Zero, a coalition of non-state actors including businesses, to halve emissions by 2030.

Nigel Topping, who worked on that launch and advises the UAE official responsible for connecting government with non-state actors, said it was important to include the people with the "money and resources".

"People say it's a trade show, it's a jamboree, but it's a collaborative effort to find and accelerate the solutions to get to net zero," Topping said.

The We Mean Business Coalition, a forum for companies pushing for pro-climate policies set up in 2014, coordinated a letter from over 200 business leaders to the UNFCCC ahead of COP28 calling for the phase out of fossil fuels.
