C-zero Markets

What C-zero Markets does

C-Zero Markets is a UK-headquartered environmental commodities broker and decarbonisation advisory firm operating in the UK and European renewable energy and carbon markets. Founded in 2021 by Mike Ridler (CEO) and Bruce Brown (CCO), the company trades and advises on Renewable Energy Guarantees of Origin (REGOs), Renewable Gas Guarantees of Origin (RGGOs), Renewable Transport Fuel Certificates (RTFCs), compliance carbon allowances (UK-ETS, EU-ETS), and voluntary carbon credits. Its two primary customer segments are renewable energy generators seeking to maximise asset value through certificate monetisation, and corporate buyers seeking to meet Scope 1/2/3 decarbonisation, compliance, and voluntary ESG targets.

The firm's commercial offering rests on human advisory expertise rather than proprietary technology platforms. It publishes proprietary market intelligence (European Biomethane Certificate Market Report) and integrates Wilhelmsen's Platform 13 for maritime Scope 3 visibility via the C-Zero Maritime subsidiary launched in 2025. A 2025 joint venture with Mast Energy Developments extends the model from pure brokerage into physical power supply development for AI data centres. Revenue is generated through transaction fees/spreads on certificate trades, professional services fees for advisory and emissions strategy work, and project-based managed services tied to JV partnerships.

The business is founder-owned, privately held, and operates with a small team of approximately six professionals from London (HQ at Hanover Square) with a correspondence address in Farnham. It holds membership in the Energy Ombudsman Broker ADR Scheme. Named enterprise counterparties include Drax, AstraZeneca, Wilhelmsen Port Services, and Mast Energy Developments. No external funding rounds, institutional investors, or revenue figures are disclosed.

Expansion highlights5 records

Emerging players

• Pachama: Digital marketplace for nature-based carbon credits leveraging satellite monitoring and ML verification. Comparable to C-Zero's voluntary carbon brokerage vertical, with a more technology-led approach and focus on nature-based removal credits.
• ClimeFi: European carbon-marketplace platform focused on high-integrity removal credits. Comparable to C-Zero's voluntary carbon advisory business, with a more curated, removal-focused credit portfolio and a digital-brokerage model.
• AlliedOffsets: Carbon-market intelligence platform and brokerage supporting voluntary carbon transactions and price discovery. Comparable to C-Zero's voluntary carbon credit broking and market-intelligence activities, with a stronger data-software orientation.

Broad incumbents

• DNV: Global certification and advisory firm providing energy advisory, GHG verification, and climate-related assurance services. Overlaps with C-Zero on the advisory, GHG accounting, and ESG reporting side, particularly for regulated corporates needing assurance-grade output.
• ENGIE Impact: Sustainability consulting arm of global utility ENGIE, providing decarbonisation strategy, renewable energy procurement, and carbon advisory. Comparable to C-Zero's corporate-buyer offering but as part of a much broader energy and services portfolio.
• Statkraft: Europe's largest renewable energy producer and a major originator/trader of Guarantees of Origin and other environmental commodities. Comparable to C-Zero on the REGO/RGGO trading side, though as a vertically integrated state-owned utility rather than a specialist broker.

Direct peers

• Carbon Trust: UK-based climate-change advisory organisation providing carbon footprinting, carbon credit advisory, and certification services to corporates. Comparable to C-Zero on the advisory side, particularly for Scope 1/2/3 emissions strategy and voluntary carbon procurement.
• South Pole: Global carbon-credit project developer and broker offering voluntary carbon offsets, carbon-insetting, and corporate climate strategy. Comparable to C-Zero's voluntary carbon advisory and offset-procurement offering, though at significantly larger scale and with proprietary project pipeline.
• EcoAct (a CDP company): International carbon advisory firm providing carbon strategy, offset brokerage, and climate reporting. Directly comparable to C-Zero's Scope 1/2/3 decarbonisation advisory and voluntary carbon credit procurement services for corporate buyers.
• EDL Energy: UK-based broker and advisory firm specialising in renewable energy certificates (REGOs, RGGOs), carbon credits, and compliance markets. Closest direct competitor to C-Zero in the UK environmental commodity brokerage space, serving similar generator and corporate-buyer clienteles.
