What C2Zero does

C2Zero is a Sydney-based climate tech company operating as an ingredient brand that converts everyday purchases into permanent carbon emissions reductions. The company purchases emissions allowances from regulated compliance markets (notably the UK Emissions Trading Scheme), locks them in its digital vault CEDO, and embeds serialized micro-credit tokens — one million micro-credits per tonne of CO2e — into partner products and services so that the underlying allowances can never be surrendered by big polluters. Core technology is a distributed ledger registry with independent auditing, supporting full provenance from allowance purchase through consumer scanning via the C2Zero Scanner app. The company sells Carbon Cancellation Certificates to consumers (eCertificates starting at A$35) and to enterprises via multi-year contracts, and operates C4S (City Carbon Cancellation Service) in the UK. It also publishes the Real Carbon Price Index with Monash Centre for Financial Studies and SparkChange.

The business model combines B2B direct sales (large enterprise deals such as LGPS Central, plus brand partnerships integrating the C2Zero brandmark into physical products) with B2C e-commerce (eCertificates) and a self-serve UK platform (C4S). Revenue is generated via transaction-fee spreads on allowance purchases and unit-pricing on certificates, with multi-year enterprise contracts for businesses embedding carbon amounts commensurate with — and often exceeding — their product footprints. Customer segments span environmentally-conscious consumers, progressive SMBs (e.g., specialty coffee roasters, eco apparel, recycled eyewear), financial institutions and pension funds seeking regulated residual emissions management, event organizers (TEDxHobart, TEDxSydney, IMAA), and industry associations (AANA). The firm runs a horizontal segmentation approach across these verticals, with named partnerships exceeding 19 brands plus industry bodies in Australia and the UK. Geographic footprint is currently Australia (HQ at Rozelle, NSW) and the UK, with accelerator participation (Climate Salad Global Growth Program 2024) signaling intent for further international expansion. The company is privately held (C2Zero Holdings Pty Ltd), has 1-10 employees, and has not disclosed external institutional funding.

Direct peers

• Cloverly: Carbon offsetting API for ecommerce and logistics, used by Shopify and other platforms. Peer to C2Zero because both sell 'embedded carbon at point of purchase' and partner with brands to attach verified carbon removal to consumer transactions.
• Pachama: Marketplace and analytics platform for nature-based carbon credits with strong provenance and verification features. Comparable to C2Zero as both target enterprise buyers seeking high-integrity carbon claims, though Pachama focuses on nature-based credits rather than compliance allowances.
• Patch: API-first platform for businesses to purchase carbon credits and embed offsets into products and checkout flows. Shares C2Zero's 'embedded carbon into everyday products' ingredient-brand thesis and offers developer-facing tooling for partner integrations.
• Climate Impact X (CIX): Singapore-based carbon exchange operating spot and futures markets for verified carbon credits. Like C2Zero, CIX is building an exchange-grade venue for trading and retiring environmental commodities with provenance tracking, though CIX focuses more on the voluntary market while C2Zero emphasizes compliance ETS allowances.
• AirCarbon Exchange (ACX): Dubai-based carbon trading exchange listing both compliance (EU/UK allowances) and voluntary credits. Most directly comparable to C2Zero because it offers transparent, auditable trading of ETS allowances to corporate buyers seeking verified retirement.
• Carbonplace: Digital infrastructure for the voluntary carbon market, providing registry, trading, and retirement rails operated by major energy and trading firms. Comparable to C2Zero because both are building tech infrastructure that makes buying and retiring carbon instruments simple, transparent, and auditable.

Broad incumbents

• South Pole Group: Large climate consultancy and project developer active across voluntary and compliance carbon markets. Broader incumbent offering portfolio includes advisory, project origination, and trading — overlapping with C2Zero's allowance procurement and retirement expertise.
• Verra: Operator of the world's leading carbon credit standards and registry (VCS, Gold Standard-adjacent). Comparable to C2Zero because both sit at the integrity infrastructure layer for carbon claims, although Verra is voluntary-market focused and a non-profit standards body.

Emerging players

• Watershed: Enterprise carbon accounting and reduction platform used by large corporates. Adjacent because both serve enterprise carbon claims, though Watershed emphasizes measurement and reduction while C2Zero emphasizes verified retirement.

Others

• SparkChange: Carbon risk management and analytics firm, already a C2Zero partner. Ecosystem partner because it provides the carbon analytics expertise that complements C2Zero's allowance retirement infrastructure.
