The UK's Billion-Dollar Bet on Carbon Credits: Inside the City of London's New Roadmap
Reading Time: 7min
On April 23, 2026, the City of London Corporation and the UK Carbon Markets Forum published a remarkable report entitled “Taking advantage of the UK’s carbon certificate market: measuring value to enable action”.
A data-driven argument for why CO2 certificate markets are no longer a green niche, but a serious financial opportunity. We have read the report for you.
Note: All amounts in the original report are given in US Dollars or British Pounds. For better readability, we have converted them to Euros at the exchange rate as of May 2026. Original currencies are listed in brackets.
Summary
The UK carbon market ecosystem already generates approximately €1.4 billion Gross Value Added (£1.2 billion) today, securing over 11,000 jobs.
The global market is projected to grow 50 to 190 times by 2050, reaching up to approximately €213 billion ($250+ billion).
The UK leads in three key segments: Insurance, Rating, and Carbon Dioxide Removal (CDR) technologies.
The real opportunity lies in the ecosystem—not in the CO2 price itself.
For Planet2050, the report confirms the relevance of our business model: building a digital financial infrastructure for carbon assets.
Key Figures
The report provides hard data to back up what has previously been a vague narrative. The UK carbon credit ecosystem already generates around €1.4 billion (£1.2 billion) in Gross Value Added annually and secures over 11,000 direct and indirect jobs across more than 550 companies.
The global growth prospects are also remarkable:
The worldwide market for CO2 certificates currently totals around €1.2 billion ($1.4 billion). By 2050, MSCI forecasts a volume between approximately €51 billion ($60 billion) and approximately €213 billion ($250+ billion), depending on the pace of global decarbonization. Even the conservative scenario represents a 50-fold increase.
The optimistic scenario: 190-fold.

The industry forecast from BeZero Carbon (Vision 2035) suggests that as the market matures, up to 135,000 highly skilled jobs could be created in the United Kingdom alone.
Capital is already flowing. Between 2023 and 2025:
UK banks and asset managers invested approximately €1.9 billion ($2.2 billion) in global carbon projects
UK companies invested approximately €3.1 billion ($3.6 billion) in carbon projects
UK-based carbon projects attracted approximately €3.0 billion ($3.5 billion) in international investments
UK companies in the Carbon Dioxide Removal (CDR) technologies sector alone raised approximately €2.1 billion ($2.5 billion) - in two years, in an industry that barely existed ten years ago
What's behind this? Investors are betting that CO2 removal will no longer be a voluntary endeavor but will become an economic necessity, driven by regulation, corporate climate targets, and growing demand for verifiable, permanent solutions. This is exactly the market where Planet2050 operates.
Why the United Kingdom?
Great Britain already runs a large part of the global infrastructure for carbon trading - and is now systematically expanding this to the carbon credit market.
The report bases its argument on three pillars:
Economic Strength: The ecosystem creates domestic value and jobs while serving global markets.
Service Exports: British expertise in trading, rating, insurance, and law is in demand worldwide—generating revenue that flows home.
Investment Magnet: Growing global markets attract capital into British projects and companies.

Three Facts That Stand Out
Carbon Insurance - #1 globally
Anyone buying a CO2 credit wants assurance that the underlying project will actually deliver: that the forest won't burn down, that the stored CO2 won't escape. This requires insurance—and the UK dominates this niche, anchored by Lloyd's of London.
Today, the total insured volume is around approximately €445 million (£380 million). By 2050, the annual premium volume could grow to approximately €35 billion (~£30 billion). British specialty insurers such as Kita, Artio, and Oka have already established themselves as global pioneers in this niche.
CO2 Removal Technologies - #2 globally
In terms of the number of technological CDR companies, Great Britain ranks 2nd globally, closely following the USA - with around 65 firms in areas like Direct Air Capture, Biochar, and mineralization.
The estimated value of the global market for such removal credits by 2050: approximately €406 billion ($478 billion) per year worldwide, with British demand alone accounting for approximately €3.1 billion ($3.6 billion) per year.
Carbon Credit Rating - Two Out of Five Globally
Two of the five globally leading rating agencies for CO2 certificates are based in Great Britain: Sylvera and BeZero Carbon - jointly financed with over approximately €170 million ($200 million) in venture capital. With the market's growth, these companies decide which certificates are worth buying. This is an influential position.
Why Is the United Kingdom So Well Positioned? A Concrete Example
The British government's recent step to link its Emissions Trading System with the EU's provides a foretaste of how quickly value potential can be unlocked.
The agreement is expected to:
save British companies around €340 million (£290 million) in trading costs between 2026 and 2030
save around €935 million (£800 million) in cross-border carbon taxes (CBAM)
multiply the connected market volume from approximately €71 billion ($61 billion) to approximately €1.02 trillion ($1.2 trillion) in annual trading value—a twentyfold increase
The British government alone collected approximately €3.9 billion (£3.4 billion) in tax revenue from its existing Emissions Trading System in the 2024/25 fiscal year.
Five Forces Driving Demand
The report identifies five concrete drivers of global demand—and explains which British services benefit from them:
1. Aviation Compliance starting 2027 (CORSIA)
Airlines worldwide will be obliged to offset a large part of their international emissions—with an expected cumulative demand of around 1,600 million tons of CO2 certificates by 2035. Insurers, rating agencies, and brokers will benefit directly.
2. Inter-State Trading (Article 6, Paris Agreement)
78% of countries plan to trade emission credits across borders. An entirely new governmental market is emerging—with a high need for legal and financial infrastructure.
3. Corporate Standards for Net Zero (SBTi & ISO, ~2027)
Once global guidelines are finalized, the purchasing reluctance of many companies will decrease, releasing structural demand.
4. AI-Driven Emissions from Data Centers
Technology corporations are already driving the short-term demand for high-quality CO2 removal credits—with increasing intensity.
5. Convergence of State Markets
The linking of the UK and EU ETS is an initial signal: compliance and voluntary markets are merging. This increases demand, volume, and prices for quality certificates.
What This Means for Investors
The real investment opportunity lies not in speculating on rising CO2 prices - but in the ecosystem: in companies that trade, rate, insure, and broker CO2 certificates. These firms earn fees as the market scales. It is a stable business model instead of a commodity wager.
Major players are already active:
HSBC has invested over approximately €555 million ($650 million) in natural capital solutions
Aviva Investors has launched a dedicated Carbon Removal Fund
Barclays operates an accelerator for carbon project startups, which has supported almost 150 million tons of emissions reductions to date
As the sector matures, it is expected that other specialized companies such as rating agencies, insurers, and project developers will enter the public markets, opening up new opportunities for private investors as well.

Conclusion
CO2 markets are evolving from a sustainability footnote to a serious financial sector with structural tailwinds. For investors who look beyond the media noise, the real question is not whether this market will grow - but who in the value chain is best positioned to participate.
The UK’s sophisticated strategy, combined with strong global demand drivers, lays the foundation for one of the most defining investment themes of the next 25 years.
At Planet2050, this is precisely our focus: as a Climate FinTech, we are building the digital financial infrastructure that makes this market accessible to private investors - with high-quality, certified CO2 projects and the planned Public Listing in 2026.
