Despite Trump’s Stance, Major U.S. Companies Intensify Their Presence at Global Climate Talks

Despite tensions between the U.S. government and the global climate agenda ahead of the COP30 summit, American companies maintained a strong presence and continued to push for climate dialogue.

A Reuters analysis of attendance records shows that 60 representatives from Fortune 100 companies travelled to the Brazil summit, compared with 50 who attended last year’s meeting in Baku, Azerbaijan. Additional U.S. participants joined pre-conference events in São Paulo and Rio de Janeiro, Brazil’s financial hubs.

The U.N.’s provisional list of official summit attendees featured major firms including Microsoft, Google, Occidental Petroleum, General Motors, and Citigroup.

Andrew Wilson, Deputy Secretary General for Policy at the International Chamber of Commerce, said, “We haven’t seen any significant shift in U.S. corporate engagement on climate policy this year. That was clearly reflected in attendance levels.”

He added that industries are increasingly concerned about the rising financial toll of extreme weather events—highlighting the urgent need for effective policy responses.

Executives noted that stepping back from climate discussions is not an option, as rising temperatures pose escalating risks to factories, supply chains, and overall business performance.

“We’re doing this because it’s good for business. It helps build supply security,” said Jim Andrew, Chief Sustainability Officer at PepsiCo. He noted that supporting farmers who produce key ingredients is essential for the company, which earns much of its revenue from products like Walkers crisps and Quaker Oats.

Filling the Gap

ExxonMobil CEO Darren Woods was among the U.S. officials, mayors, and sub-national leaders attending pre-COP events. Lou Leonard, founding dean of the School of Climate, Environment, and Society at Clark University, said these leaders will play crucial roles in shaping the future of climate action.

A recent analysis by the Center for Global Sustainability at the University of Maryland found that current federal and non-federal policies will cut U.S. emissions by 35% by 2035—most of the progress driven by companies.

Gina McCarthy, former head of the U.S. Environmental Protection Agency and now co-chair of the ‘America Is All In’ coalition, said, “Despite the headlines, the private sector continues to invest in and adopt clean energy.”
She noted that clean energy jobs in the U.S. grew three times faster than the rest of the workforce last year.

Several smaller U.S. companies also attended the two-week COP30 conference, particularly those looking to benefit from carbon markets and low-carbon energy transitions.
Brennan Spellacy, CEO of carbon credit platform Patch, said, “Being here is about global connection. Most of my meetings are with sustainability leaders and CSOs from the U.S., France, and Germany.”

The Crucial Role of U.S. Businesses

Former President Donald Trump has repeatedly dismissed climate change as a hoax. Yet, despite the official U.S. stance, global regulations aimed at accelerating the energy transition continue to evolve—even if COP30’s final agreement left some participants disappointed.

Jack Hurd, who leads the World Economic Forum’s Earth Systems Agenda and Tropical Forest Alliance, said, “Regardless of U.S. political rhetoric, the market is moving forward—and policymakers are recognizing that direction.”

Data from disclosure platform CDP shows more U.S. companies are reporting their climate strategies, despite the country’s decision not to move ahead with a federal climate disclosure rule. However, the overall quality of global corporate climate plans remains insufficient.

Maria Mendiluce, CEO of the We Mean Business Coalition, said U.S. involvement at COP30 was essential whether or not they were present at the main sessions. “The U.S. plays a pivotal role in global climate, energy, and industrial policy. That’s why participation from sub-national leaders, non-state actors, and businesses matters.”

She added that even when domestic politics fluctuate, the U.S. continues to shape global markets, capital flows, and technological pathways. Its engagement signals to investors that the world’s largest economy understands the competitiveness, innovation, security, and supply chain stakes of the energy transition.
