Carbon Capture Promoters Turn Up In Numbers At COP30: NGO

Companies and groups backing carbon-capture technology, which critics slam as an excuse to keep burning fossil fuels, have deployed more than 500 participants to the COP30 climate talks, according to a list compiled by an NGO and shared exclusively with AFP.

The list, assembled by the Center for International Environmental Law (CIEL), names oil and gas giants such as ExxonMobil, Shell, and BP, along with Brazil's state-owned Petrobras and China National Petroleum Corp.

CIEL's inventory is broad, with the likes of US tech giant Amazon, the Port of Antwerp-Bruges, and Canadian company West Fraser Timber joining more obvious groups such as the Global CCS Institute.

CIEL classified a total of 531 attendees at the UN talks in Belem, Brazil, as "lobbyists" for firms or groups that promote carbon capture and storage (CCS).

Their number "highlights the large amounts of energy and power the fossil fuel industry is investing to secure its future by selling the idea that governments and companies can 'clean' their use of coal, oil, and gas by capturing and 'managing' emissions," CIEL said.

The NGO said there were 475 CCS lobbyists registered at COP28 in Dubai and 480 at COP29 in Baku -- both of which had more total participants than the conference in Belem.

CCS is a controversial technology.

The IPCC, the UN's expert scientific panel on climate change, says carbon capture is one option for reducing emissions, including in heavy polluting sectors like cement and steel.

CCS equipment captures CO2 at its source -- such as power plants or industrial facilities -- or pulls it directly from the air before it is stored in deep underground rock formations.

But it remains expensive and technically complex to deploy at scale, giving it a tiny part in addressing the climate crisis for now.

"We need carbon capture because we will overshoot (the goal of limiting warming to 1.5 °C)," US Senator Sheldon Whitehouse, a Democrat and advocate for strong climate action in Congress, told AFP in Belem.

"It just can't be the excuse for polluting more," Whitehouse said.

CIEL said oil companies are using the energy demand from the booming AI sector as justification to keep drilling.

"CCS cannot make fossil fuels 'clean' -- it just keeps them burning," said CIEL fossil economy director Lili Fuhr.

"The world doesn't need fossil-fueled tech-fantasies justifying business as usual for big polluters and Silicon Valley billionaires," Fuhr said.

A separate analysis by Kick Big Polluters Out found that more than 1,600 attendees were part of companies or groups with ties to the fossil fuel industry.

CIEL said that to be classified as a carbon capture lobbyist, a company or organization has to be involved in a CCS project, have a track record of lobbying for the technology, or state that its purpose includes promoting CCS.

The NGO verified the information on company websites, the International Energy Agency's CCS project database, news sources, and lobbying registers, among other sources.

More than 40 "CCS lobbyists" are part of national delegations at COP30, including Russia, Gulf countries, and Brazil, according to CIEL.

Barnaby Pace, senior researcher at CIEL, acknowledged that the NGO cannot be certain if a company was sending someone to talk about CCS at COP30.

"We can't quite predict that, but it is going to be part of their agenda if they are going down this line, and we think that's problematic," he told AFP.
