Ahead of the annual Conference of the Parties (COP28) climate negotiations, enacting policies that expose the influence of corporate polluters in UNFCCC meetings will help ensure that climate science takes precedence over climate delay and greenwashing. To that end, we urge you (i) to engage in diplomatic efforts to secure the withdrawal of the president-designate of COP28; and (ii) to take immediate steps to limit the influence of polluting industries, particularly major fossil fuel industry players whose business strategies lie at clear odds with the central goals of the Paris Agreement, at gatherings of the UNFCCC.

Last year, many of us attended or followed COP27 in Sharm-al-Sheikh, Egypt. While we applaud the United Nations for bringing tens of thousands of delegates together, leading to a historic agreement that will help developing countries deal with losses and damages from the impacts of climate change, the conference ultimately failed to secure consensus from Parties to cut greenhouse gases in line with the agreed global goals.

It did not escape our attention that at least 636 lobbyists from the oil and gas industries registered to attend last year's COP —an increase of more than 25 percent over the previous year.

When the number of attendees representing polluting corporate actors, which have a vested financial interest in maintaining the status quo, is larger than the delegations of nearly every country in attendance, it is easy to see how their presence could obstruct climate action.

As you know, there is no time to waste in sharply cutting carbon pollution on a global scale. The latest Intergovernmental Panel on Climate Change (IPCC) report states that, to limit warming to 1.5°C, global emissions must halve by 2030. The planet has already warmed over 1.2°C, and our ability to reach the 1.5°C goal is moving fast out of reach, with the IPCC pegging the current probability at just 38 percent. Maintaining the status quo would lead to a catastrophic 2.8°C temperature rise by the end of the century.

In this moment of great urgency, we must unblock the barriers that have kept us from advancing strong global collaboration to address climate change. One of the largest barriers to strong climate action has been and remains the political influence and obstruction of the fossil fuel industry and other major polluting industries.

We have seen their negative influence in our home institutions; oil companies and their industry cheerleaders have spent billions of dollars lobbying both the European Parliament, other European institutions and member states, and the US Congress in order to obstruct or water down climate policy for years.

While we acknowledge that engaging with industry can play a role, we must consider this particular industry's track record on climate. Since at least the 1960s, the fossil fuel industry has known about the dangers of climate change posed by its products and, rather than supporting a transition to a clean energy future, has instead chosen to promote climate denial and spend millions of dollars to spread disinformation.

Over a half century later, not one of 39 major global oil and gas companies, with collective market capitalisation of $3.7 trillion [€3.43 trillion], has adopted a business strategy that would limit warming to safe levels. Several independent analyses agree that the sector is still not taking meaningful action to avoid the worst impacts of the crisis.

Even more outrageous, the global oil and gas industry is expanding amid blockbuster profits to the tune of $4 trillion last year. The sector has poured $160bn into exploration for new fossil reserves since 2020, even as the IEA has stated that no new fossil fuel projects are compatible with limiting warming to 1.5°C. In short, in the words of UN secretary general Antonio Guterres, "We seem trapped in a world where fossil fuel producers and financiers have humanity by the throat." It is time to alter this dangerous course.

In June, world governments will gather in Bonn for the UN Climate Change Conference, a critical opportunity to advance progress towards implementation of the Paris Agreement, in anticipation of COP28. It is essential that we seize the opportunity to take actionable steps to address and protect climate policy from polluting interference by adopting concrete rules that limit the influence of the fossil fuel industry and its lobbyists in the UNFCCC decision-making process.

First, we urge you to advocate for the United Arab Emirates to withdraw the appointment of Sultan Al Jaber, head of the Abu Dhabi National Oil Company, as president-designate of COP-28. The decision to name as president of COP28 the chief executive of one of the world's largest oil and gas companies—a company that has recently announced plans to add 7.6bn barrels of oil to its production in the coming years, representing the fifth largest increase in the world — risks undermining the negotiations.

With common sense reforms to help restore public faith in the COP process severely jeopardised by having an oil company executive at the helm, we respectfully submit that different leadership is necessary to help ensure that COP28 is a serious and productive climate summit.

Second, as some of us have already urged, we request that you institute new policies for corporate participation at COPs and UNFCCC processes more broadly, including requiring participating companies to submit an audited corporate political influencing statement that discloses climate-related lobbying, campaign contributions, and funding of trade associations and organisations active on energy and climate issues.

These statements should be reviewed, publicly disclosed, and scrutinised prior to any engagement in UNFCCC climate policymaking processes. The UNFCCC should also consider additional measures to establish a robust accountability framework to protect against undue influence of corporate actors with proven vested interests that contradict the goals of the Paris Agreement; such a framework was proposed last year with broad-based international support from over 450 organisations around the world and five UNFCCC constituencies representing thousands of organisations and millions of people. These reforms would bring much-needed transparency to corporate climate-related political influencing activities around the world, and would help restore public faith that the COP process is not being abused by companies as an opportunity to greenwash.

Thank you for your attention to this important issue and for your ongoing dedication to building global support for reducing carbon pollution and combating climate change. We welcome further engagement with you on this topic, and the lead co-signers are available to meet with you at a mutually agreeable time prior to the UN Climate Change Conference in June.
