Weeks before African leaders travelled to Nairobi for the continent’s first climate summit in September, climate justice groups wrote to Kenyan president William Ruto accusing consultancy firm McKinsey of “undue influence” on the summit’s agenda.
The American firm had offered Ruto support in running the summit during a meeting with him and US ambassador to Kenya Meg Whitman in late May, several sources told Climate Home News.
A few days later, in early June, McKinsey wrote the concept note, which set the summit’s structure, and later drafted a paper to frame its outcome.
“For a few weeks, it was their way or the highway,” a source close to the summit’s organisation told Climate Home.
At the time, the Kenyan government said civil society accusations that Mckinsey had captured the summit were “extremely far from the truth”. McKinsey said the claims were “inaccurate”.
But the backlash publicly exposed the influence McKinsey wields on Africa’s climate agenda – a position it would prefer to keep discreet.
Leaked documents
Now, Climate Home has obtained leaked documents and interviewed multiple sources, who have asked to remain anonymous because of the sensitivity of the issue.
They show how McKinsey dominates an ecosystem pushing carbon markets in Africa and processes designed to help governments develop long-term energy plans.
This has been facilitated by McKinsey’s deep-rooted ties with Sustainable Energy For All (SEforAll), which is responsible for delivering on a 2030 sustainable development goal for everyone to have access to affordable, reliable and sustainable energy; and the Global Energy Alliance for People and Planet (GEAPP), which works to accelerate the energy transition.
Climate Home’s investigation reveals that SEforAll staff complained of CEO Damilola Ogunbiyi’s “preferential treatment” of McKinsey in a whistleblower report in 2020.
That year, SEforAll brought in the firm to facilitate a leadership retreat and develop the organisation’s business plan. At the time, SEforAll’s top management dismissed the allegation.
Three years on, documents show how McKinsey has turned initial pro-bono work into lucrative contracts.
A source close to SEforAll told Climate Home that McKinsey encountered hardly any competition and enjoyed “almost unrestricted access to the highest levels of the UN and national governments”.
An SEforAll spokesperson said: “All SEforALL processes are followed at all times in the selection and engagement of any advisory services,” adding that any idea to the contrary was “baseless”.
“Come to take over”
African government insiders say McKinsey’s domination is problematic because it is pushing a top-down tunnel vision and non-Afro-centric view of how to address the continent’s climate and development challenges, which, if unquestioned, could constrain its ambition.
“The role of McKinsey is highly problematic because they don’t come in a capacity support role, they come to take over,” said one source.
There is a role for consultants to help governments and international organisations plug skill and knowledge gaps.
But consultancies should advise “from the sidelines in a transparent way… rather than be allowed to run the show from the centre,” economist Mariana Mazzucato and researcher Rosie Collington write in their book about the consulting industry The Big Con.
Michael Marchant is head of investigations at Open Secrets, an NGO which advocates for private sector accountability and investigated McKinsey’s work in South Africa.
He told Climate Home that despite receiving large amounts of public money, large consultancy firms like McKinsey “operate in secrecy and with almost no public accountability”.
Heart of climate governance
Yet, allowed in by governments, McKinsey has found a place at the heart of critical climate governance processes. France24 recently reported that McKinsey is pushing fossil fuel interests in its advisor role to the UAE, which will preside over the Cop28 climate talks in Dubai starting next week.
The company’s client list includes some of the world’s biggest fossil fuel companies, including Saudi Aramco, Chevron, ExxonMobil, and Shell, according to court filings in the US, where McKinsey is being sued alongside Big Oil. McKinsey rejects the accusations.
In more recent years, McKinsey has advised polluters, including oil and gas companies, on how to use the carbon market to offset their emissions or raise revenue. A 2022 internal McKinsey document, seen by Climate Home, names Chevron and BP among clients of its carbon market business line.

In Africa, the consultancy is behind a push to significantly grow the continent’s carbon offset offering, working closely with both GEAPP and SEforAll.
In 2021, McKinsey supported the Rockefeller Foundation to design and establish GEAPP, according to a McKinsey document seen by Climate Home. The following year, GEAPP asked SEforAll to hire McKinsey to develop the African Carbon Market Initiative for $1.5 million as part of its grant to the organisation, Climate Home understands.
Launched at Cop27 in Egypt, the initiative aims to scale carbon markets on the continent 19-fold by 2030.
While GEAPP and SEforAll publicly sponsored the initiative, McKinsey described its role in a sustainability report as “shaping and refining the initiative’s ambition” and “developing its strategy”. McKinsey’s concept note for the Africa Climate Summit elevated carbon markets to a core theme.
President Ruto appointed Joseph Ng’ang’a, GEAPP’s vice president of Africa, CEO of the summit.

Climate campaigners denounced the focus on carbon markets as “a dangerous distraction” from African climate priorities and accused McKinsey of working to protect the interests of its western corporate clients.
McKinsey has repeatedly dismissed these allegations, arguing there is no way to deliver emissions reductions without working with high-emitting industries and that it has rigorous policies to manage conflict of interests.
A spokesperson for the company said “sustainability is a mission-critical priority for McKinsey”, which has “committed to rapidly scale this work to help clients in all industries reach net zero by 2050”.
A GEAPP spokesperson said it was established “to unite a diverse range of partners” to rapidly facilitate a global shift towards renewable energy. In doing so, it “leverages a spectrum of… experts and consultants”.
A close relationship
McKinsey’s rapidly growing climate work in Africa has been facilitated by a close relationship between its African Sustainability Practice lead Adam Kendall and SEforAll’s CEO Ogunbiyi, who also serves as a UN special representative for sustainable energy.
Before joining SEforAll, Ogunbiyi worked closely with Kendall, who led McKinsey’s natural gas practice in Lagos, Nigeria. He helped build the Nigerian vice president’s advisory power team and worked with the Rural Electrification Agency, which Ogunbiyi both headed.
A McKinsey document describing its previous work for SEforAll said the firm “provided strategic support to Ms. Ogunbiyi during her transition” into her new CEO role, starting in January 2020.
Weeks later, Kendall was invited to co-facilitate an SEforAll leadership retreat in London and subsequently developed the organisation’s 2021-2023 business plan, effectively for free.

The same year, McKinsey seconded employee Ugo Nwadiani to SEforAll. An SEforAll recruitment note shows he was directly appointed Ogunbiyi’s special assistant.
Whistleblower report
An anonymous complaint prepared by several SEforAll staff raised concerns about these developments.
A source said the complaint was backed widely among employees and sent to the organisation’s whistleblowing account and to one of its major funders.
It described “a culture of fear” at SEforAll, and accused Ogunbiyi’s leadership of being “marked by favouritism”, including towards McKinsey.
During the business planning process, McKinsey “had direct access to SEforALL financial information and organizational systems and processes” putting the company “in a privileged position” to apply for any future tender, it said.
It raised concerns that McKinsey had been the only firm asked to comment on terms of reference for work to update Nigeria’s integrated energy plan which SEforAll was seeking to contract out. McKinsey had worked with the Nigerian government on the first version of the plan the previous year. It was eventually hired for the job.
Responding to the complaint at the time, SEforAll’s management said it had strengthened procurement oversight and put in place mechanisms to help “create a climate of trust”.
Since then, SEforAll has hired McKinsey to work on at least three of its five core initiatives in Africa: developing energy transition plans, scaling up the carbon market, and boosting renewable energy manufacturing capabilities.
Francesco Starace, chair of SEforAll’s governance board, said the board was satisfied with the outcome of a review process following the complaint. “We are confident with the integrity of the SEforALL procurement process and the leadership demonstrated by the CEO and the executive management team,” he said.
McKinsey’s work in Nigeria
McKinsey’s extensive work for SEforAll in the early days of Ogunbiyi’s leadership set it up for further opportunities.
In Nigeria, McKinsey provided the modelling which underpins the country’s energy transition plan pro bono, working with SEforAll and the former government. A new government, which came into office in May, has warned that it will need a lot more investment to deliver
Chukwumerije Okereke, a Nigerian climate governance expert, said the exercise was a “cautionary tale”. The use of McKinsey-owned tools prevented robust scrutiny of the assumptions in the model, he told Climate Home. And the “closed door” process and lack of consultation may partly explain diminished political momentum to implement it, he added.
Ghana’s flood victims blame government for overflowing dam destruction
More recently, SEforAll and Kendall’s McKinsey team have sought funding to develop energy transition plans in up to ten developing countries, according to a 2021 joint concept note for funders, obtained by Climate Home.
With support from Bloomberg Philanthropies, the pair has developed a plan for Ghana, and is working to do the same in Kenya and Barbados using a joint open-source model. In Kenya, draft plans, seen by Climate Home, would increase gas power capacity in the 2040s.
SEforAll told Climate Home these plans were procured through an open and transparent process, rigorously peer reviewed and subject to civil society consultations.
For Okereke, international consultants can bring quality and gravitas to energy planning. “But it’s about the way they do it.”

DeBriefed 19 June 2026: Bonn talks end in ‘gridlock’ | Energy’s ‘new era’ | Oceans in climate negotiations
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Bonn talks close
‘SIDE-STEPPING AND STALLING’: UN climate talks in Bonn have ended in “gridlock”, according to Climate Home News. The outlet reported on the failure to balance developing countries’ need for climate-adaptation finance with “richer nations’ desire to move forward” on emissions cuts. It added that both topics were subject to “rule 16”, meaning no agreement could be reached and work will be pushed to the COP31 summit in Turkey. Inside Climate News quoted UN climate executive secretary Simon Stiell, who said the talks had seen “side-stepping and stalling”.
JUST TRANSITION: One “glimmer of hope” came from negotiations on achieving a “just transition”, reported Euronews. The news outlet said negotiators “made headway on operationalising the Belém-Antalya mechanism”, intended to support people in the shift to a low-carbon economy. However, Politico concluded that much of the focus in Bonn had “shift[ed] to efforts outside diplomatic talks – raising questions about the future of global climate negotiations”.
‘ATTACKING SCIENCE’: Agence France-Presse reported on the EU, Switzerland and “dozens of developing nations” warning of “attacks on science” by a “small group of fossil-fuels interests” in Bonn. Table Briefings explained that “the 1.5C target is increasingly being challenged” and the role of the UN climate-science panel – the Intergovernmental Panel on Climate Change (IPCC) – in an upcoming assessment of global climate progress “remains controversial”. See Carbon Brief’s full write-up of the talks for more detail.
US-Iran deal
PRICE DROP: The US and Iran announced that they have reached an interim agreement to halt the war and reopen the strait of Hormuz, reported Bloomberg. Oil prices have fallen, as the “long-awaited deal” began the process of “eas[ing]” the global energy crisis triggered by the conflict, according to the New York Times. The Associated Press noted that high fuel prices will “likely outlast the Iran war”.
‘OIL GLUT’: The Financial Times reported that the International Energy Agency (IEA) has forecast a “glut of oil” emerging next year, if the peace deal holds. The IEA said this would allow countries to build new strategic reserves, as they “review their energy strategies and policies in response to the crisis”, according to Reuters.
‘NEW ERA’: Agence France-Presse reported that oil and gas companies have “few illusions about a return to normal for the Gulf energy industry after more than three months of blockage”. One analyst told the newswire that the war “showed the oil and gas industry that Hormuz risk is no longer just a geopolitical headline”.
Around the world
- OCEAN MONITOR: The Trump administration is “abandoning its plan” to dismantle a $368m ocean monitoring system key for tracking climate change after a “bipartisan backlash on Capitol Hill”, reported the New York Times.
- CORAL HAVEN: The New York Times covered preliminary research, presented at the Our Ocean Conference in Kenya, suggesting there could be three times as many “coral refugia” – where corals are relatively safe from climate change – than previously thought.
- BAD CREDIT: Down to Earth reported that the first carbon credits issued under the Paris Agreement’s new Article 6.4 mechanism are “facing scrutiny over alleged links to institutions controlled by Myanmar’s military junta”.
- OIL BACKTRACK: Reuters reported that oil-and-gas company Equinor has dropped a renewable-energy target and scaled back clean investments, while another Reuters story noted that Shell is selling off its offshore wind assets.
1.1 billion
The number of children facing “at least three overlapping climate hazards”, according to a new Unicef report covered by Agence France-Presse.

Captured
The more than 2m battery electric vehicles (BEVs), 1m “plug-in” hybrids (PHEVs) and 100,000 electric vans on UK roads are already saving drivers a total of around £3bn a year, according to new Carbon Brief analysis. This amounts to savings of more than £1,100 a year in fuel costs for each BEV driver in the UK. The analysis comes amid reports in UK media this week that the government is considering “watering down” its EV sales targets.
Spotlight
Oceans rising at UN climate talks
The state of the world’s oceans is inextricably linked to the changing climate – and many delegates at UN climate talks want to see more focus on this issue, reports Carbon Brief.
Oceans are often described as the world’s “greatest ally” against climate change – absorbing 30% of carbon dioxide (CO2) emissions and most of the heat generated by those emissions.
They are also the site of important climate solutions, such as huge offshore windfarms and the shipping industry’s transition to cleaner fuels.
At the same time, the oceans themselves present a growing danger to coastal communities and sea life due to sea level rise, marine heatwaves and ocean acidification.
These diverse issues have led to growing calls within the UN climate process for more focus on oceans. During climate negotiations this week in Bonn – known as SB64 – nations and civil society had a chance to air these views during an “ocean and climate change dialogue”.
‘Elevate action’
Oceans first entered UN climate outcomes in 2019, when the final COP25 negotiated text requested a new “dialogue” on “the ocean and climate change to consider how to strengthen mitigation and adaptation action”.
The following years saw this dialogue established as an annual event. However, the political weight of these discussions has been limited.
COP31 is being co-led by Turkey and Australia, but with Pacific islands playing a supporting role. These small islands sometimes self-identify as “large ocean states”, stressing the ocean’s centrality in their societies.
In Bonn, figures from across the presidency threw their weight behind this issue. Chris Bowen, an Australian minister and incoming COP31 “president of negotiations”, told attendees:
“Australia, Turkey and the Pacific see an important opportunity to elevate ocean-based climate action.”

Strategies and finance
The two-day dialogue in Bonn involved a series of panels, statements and breakout groups.
One of the main topics was how oceans are integrated into national climate plans under the Paris Agreement, known as “nationally determined contributions” (NDCs).
Three-quarters of the latest round of NDCs mention oceans, with conservation of “blue carbon” ecosystems the most frequently described action. (Landscapes such as mangroves can both absorb CO2 and protect coastal areas.)
Delegates also discussed alignment with the UN biodiversity process, as well as ocean finance, which currently makes up less than 1% of all climate finance.
(As discussions were taking place in Bonn, country officials also gathered in Mombasa, Kenya for the 11th Our Ocean Conference. Carbon Brief’s associate editor Giuliana Viglione attended the conference and will publish a full summary shortly.)
Developing countries were clear that many of the ocean-related actions in their NDCs would depend on receiving more financial support.
‘Political momentum’
With the backing of the COP31 presidency, delegates were hopeful about where this year’s dialogue could lead.
Charles Hamilton, an advisor for the Bahamas who spoke for the Alliance of Small Island States (AOSIS) in the dialogue, told Carbon Brief that island representatives “are not traveling thousands of miles to just talk and pat ourselves on the back”. He added:
“A dialogue that just remains a dialogue is just more talk – no action.”
Given that, he said “discussions in the dialogue must move into COP decisions and the decisions must be actioned”, noting the importance of finance.
Marina Corrêa, oceans lead at WWF-Brazil, pointed to an upcoming UN climate change Standing Committee on Finance forum as a space to ramp up pressure on ocean finance.
More broadly, she wanted to see the presidencies translate their support into a “leader-level ocean initiative” that could “mainstream” oceans across negotiations.
“We have a really interesting opportunity, in terms of political momentum,” Corrêa told Carbon Brief.
