“Carbon offsets” are a means by which businesses, governments and other entities can pay for projects that cut greenhouse gases in order to “cancel out” some of their own emissions.

The topic is contentious, as Carbon Brief’s special series on carbon offsetting has revealed.
The week began with an in-depth Q&A exploring the principles underpinning offsetting and explaining when and why problems have emerged.
Carbon Brief also published new analysis examining which companies are relying on offsets to make “net-zero” claims – and mapped where journalists and campaigners have reported cases of offset projects going wrong.
To conclude this week-long series, Carbon Brief hosted a free webinar that asked how carbon offsets can be reformed.
A video of the recording (below) is now available to watch on YouTube.
The webinar featured four panellists, all of whom have considered this question in their professional and personal lives:
- Dr Barbara Haya, director of the Berkeley Carbon Trading Project at the University of California, Berkeley.
- Kaya Axelsson, net zero policy engagement fellow at the University of Oxford.
- Laura George, governance and rights coordinator of the Amerindian Peoples Association.
- Pedro Martins Barata, associate vice president for carbon markets at the Environmental Defense Fund (EDF) and co-chair of the expert panel at the Integrity Council for the Voluntary Carbon Market (ICVCM).
While all four webinar participants saw the need for considerable change in how carbon offset markets work, their views on what needed to happen diverged considerably.
Haya was clear from the outset that, having studied offset quality for over 20 years, she has consistently found evidence that carbon-offset projects are “over-crediting” – namely, they overestimate the amount of emissions they are cutting:
“The level of over-crediting is really significant. We’re not talking 20-30% overcrediting, we’re talking five times, 10 times, 12 times over-crediting…In the end, I will argue that we need to move away from offsets. I don’t see a way to fix this market.”
The panellists discussed different ways in which offsets could be done differently, including a so-called “contribution” approach. This involves entities buying offset credits, but not counting the emissions cuts towards their own targets, meaning climate action could be supported without misleading claims being made.
Axelsson emphasised that, in her view, the money that can flow from offset purchases to “parts of the world that need that financing” is important.
Therefore, she said her focus is more on ensuring that there are high-quality offsets on the market, with more of an emphasis on offsets derived from long-term emissions storage projects. She added:
“You don’t wash your hands of something once you’ve invested. You have to watch and steward and curate it and make sure communities are involved.”
George, whose organisation promotes and advocates for the rights of Indigenous peoples in Guyana, stressed the importance of considering the rights of these groups when considering carbon-offset projects:
“Things like that can work only if we are informed properly and respect is given…Decisions that are made are impacting Indigenous peoples’ rights, our food security, land tenure security and everything else.”
Barata agreed with other speakers that without a strong regulatory framework “you do have a system where it’s everyone for themselves, nobody checks the quality” of offsets. However, he emphasised that change was possible, stating:
“I’m worried about credit quality very much – and that’s why ICVCM has been set up – and we do hope that over the next few months we will be able to change significantly the landscape of carbon credits.”
Over the course of the webinar, panellists also took questions on REDD+ forest protection schemes, new UN carbon markets and who should be responsible for reforming the trade in offsets.

For proof of the energy transition’s resilience, look at what it’s up against
Al-Karim Govindji is the global head of public affairs for energy systems at DNV, an independent assurance and risk management provider, operating in more than 100 countries.
Optimism that this year may be less eventful than those that have preceded it have already been dealt a big blow – and we’re just weeks into 2026. Events in Venezuela, protests in Iran and a potential diplomatic crisis over Greenland all spell a continuation of the unpredictability that has now become the norm.
As is so often the case, it is impossible to separate energy and the industry that provides it from the geopolitical incidents shaping the future. Increasingly we hear the phrase ‘the past is a foreign country’, but for those working in oil and gas, offshore wind, and everything in between, this sentiment rings truer every day. More than 10 years on from the signing of the Paris Agreement, the sector and the world around it is unrecognisable.
The decade has, to date, been defined by a gritty reality – geopolitical friction, trade barriers and shifting domestic priorities – and amidst policy reversals in major economies, it is tempting to conclude that the transition is stalling.
Truth, however, is so often found in the numbers – and DNV’s Energy Transition Outlook 2025 should act as a tonic for those feeling downhearted about the state of play.
While the transition is becoming more fragmented and slower than required, it is being propelled by a new, powerful logic found at the intersection between national energy security and unbeatable renewable economics.
A diverging global trajectory
The transition is no longer a single, uniform movement; rather, we are seeing a widening “execution gap” between mature technologies and those still finding their feet. Driven by China’s massive industrial scaling, solar PV, onshore wind and battery storage have reached a price point where they are virtually unstoppable.
These variable renewables are projected to account for 32% of global power by 2030, surging to over half of the world’s electricity by 2040. This shift signals the end of coal and gas dominance, with the fossil fuel share of the power sector expected to collapse from 59% today to just 4% by 2060.
Conversely, technologies that require heavy subsidies or consistent long-term policy, the likes of hydrogen derivatives (ammonia and methanol), floating wind and carbon capture, are struggling to gain traction.
Our forecast for hydrogen’s share in the 2050 energy mix has been downgraded from 4.8% to 3.5% over the last three years, as large-scale commercialisation for these “hard-to-abate” solutions is pushed back into the 2040s.
Regional friction and the security paradigm
Policy volatility remains a significant risk to transition timelines across the globe, most notably in North America. Recently we have seen the US pivot its policy to favour fossil fuel promotion, something that is only likely to increase under the current administration.
Invariably this creates measurable drag, with our research suggesting the region will emit 500-1,000 Mt more CO₂ annually through 2050 than previously projected.
China, conversely, continues to shatter energy transition records, installing over half of the world’s solar and 60% of its wind capacity.
In Europe and Asia, energy policy is increasingly viewed through the lens of sovereignty; renewables are no longer just ‘green’, they are ‘domestic’, ‘indigenous’, ‘homegrown’. They offer a way to reduce reliance on volatile international fuel markets and protect industrial competitiveness.
Grids and the AI variable
As we move toward a future where electricity’s share of energy demand doubles to 43% by 2060, we are hitting a physical wall, namely the power grid.
In Europe, this ‘gridlock’ is already a much-discussed issue and without faster infrastructure expansion, wind and solar deployment will be constrained by 8% and 16% respectively by 2035.

This pressure is compounded by the rise of Artificial Intelligence (AI). While AI will represent only 3% of global electricity use by 2040, its concentration in North American data centres means it will consume a staggering 12% of the region’s power demand.
This localized hunger for power threatens to slow the retirement of fossil fuel plants as utilities struggle to meet surging base-load requirements.
The offshore resurgence
Despite recent headlines regarding supply chain inflation and project cancellations, the long-term outlook for offshore energy remains robust.
We anticipate a strong resurgence post-2030 as costs stabilise and supply chains mature, positioning offshore wind as a central pillar of energy-secure systems.
Governments defend clean energy transition as US snubs renewables agency
A new trend is also emerging in behind-the-meter offshore power, where hybrid floating platforms that combine wind and solar will power subsea operations and maritime hubs, effectively bypassing grid bottlenecks while decarbonising oil and gas infrastructure.
2.2C – a reality check
Global CO₂ emissions are finally expected to have peaked in 2025, but the descent will be gradual.
On our current path, the 1.5C carbon budget will be exhausted by 2029, leading the world toward 2.2C of warming by the end of the century.
Still, the transition is not failing – but it is changing shape, moving away from a policy-led “green dream” toward a market-led “industrial reality”.
For the ocean and energy sectors, the strategy for the next decade is clear. Scale the technologies that are winning today, aggressively unblock the infrastructure bottlenecks of tomorrow, and plan for a future that will, once again, look wholly different.

IMO head: Shipping decarbonisation “has started” despite green deal delay
The head of the United Nations body governing the global shipping industry has said that greenhouse gases from the global shipping industry will fall, whether or not the sector’s “Net Zero Framework” to cut emissions is adopted in October.
Arsenio Dominguez, secretary-general of the International Maritime Organization, told a new year’s press conference in London on Friday that, even if governments don’t sign up to the framework later this year as planned, the clean-up of the industry responsible for 3% of global emissions will continue.
“I reiterate my call to industry that the decarbonisation has started. There’s lots of research and development that is ongoing. There’s new plans on alternative fuels like methanol and ammonia that continue to evolve,” he told journalists.
He said he has not heard any government dispute a set of decarbonisation goals agreed in 2023. These include targets to reduce emissions 20-30% on 2008 levels by 2030 and then to reach net zero emissions “by or around, i.e. close to 2050”.
Dominguez said the 2030 emissions reduction target could be reached, although a goal for shipping to use at least 5% clean fuels by 2030 would be difficult to meet because their cost will remain high until at least the 2030s. The goals agreed in 2023 also included cutting emissions by 70-80% by 2040.
In October 2025, a decision on a proposed framework of practical measures to achieve the goals, which aims to incentivise shipowners to go green by taxing polluting ships and subsidising cleaner ones, was postponed by a year after a narrow vote by governments.
Ahead of that vote, the US threatened governments and their officials with sanctions, tariffs and visa restrictions – and President Donald Trump called the framework a “Green New Scam Tax on Shipping”.
Dominguez said at Friday’s press conference that he had not received any official complaints about the US’s behaviour at last October’s meeting but – without naming names – he called on nations to be “more respectful” at the IMO. He added that he did not think the US would leave the IMO, saying Washington had engaged constructively on the organisation’s budget and plans.
EU urged to clarify ETS position
The European Union – along with Brazil and Pacific island nations – pushed hard for the framework to be adopted in October. Some developing countries were concerned that the EU would retain its charges for polluting ships under its emissions trading scheme (ETS), even if the Net Zero Framework was passed, leading to ships travelling to and from the EU being charged twice.
This was an uncertainty that the US and Saudi Arabia exploited at the meeting to try and win over wavering developing countries. Most African, Asian and Caribbean nations voted for a delay.
On Friday, Dominguez called on the EU “to clarify their position on the review of the ETS, in order that as we move forward, we actually don’t have two systems that are going to be basically looking for the same the same goal, the same objective.”
He said he would continue to speak to EU member states, “to maintain the conversations in here, rather than move forward into fragmentation, because that will have a very detrimental effect in shipping”. “That would really create difficulties for operators, that would increase the cost, and everybody’s going to suffer from it,” he added.
The IMO’s marine environment protection committee, in which governments discuss climate strategy, will meet in April although the Net Zero Framework is not scheduled to be officially discussed until October.
