DecarbNexus
We connect emissions to instruments to compliance: your carbon accounting, linked to instruments across a growing network of marketplaces and registries.

The opportunity
Protecting value chains from climate risk and incoming regulation means funding decarbonization at global scale. Through Scope 3 market instruments, corporations can cut through value chain complexity and provide the revenue certainty that unlocks capital upstream. Pioneering deals have proven the model, and the transaction infrastructure is built.
The problem
Funding decarbonization in your value chain means knowing where your emissions come from, which instruments can address them, and whether those instruments count. Today, each answer sits in a different system.
Your Scope 3 inventory sits in one tool, with no view of what the market can do about it.
Instruments are listed in different formats, with different pricing, quality signals, and claims.
Requirements shift with every new version, consultation, and guidance document.
The result
Nothing connects them. Discovery is inefficient, diligence takes months, and expertise is scarce, so bankable demand never reaches projects. Capital stays locked, and value chains remain exposed.
Why now
Three standards are defining how companies account for, claim, and report value chain investments. Teams that connect emissions, instruments, and compliance today will be ready as they take effect.
April 2026
Sets requirements for associating value chain investments with a company's footprint, then quantifying and reporting their impact.
June 2026
Clarifies the role of market instruments in decarbonization beyond the direct supply chain.
Expected 2028
In development, with a draft planned for 2027, to report climate actions alongside the emissions inventory.
The solution
DecarbNexus connects the information and organizations that companies need to move from emissions data to funded decarbonization.
The result
Decision-ready investment case
The platform
Each step feeds the next, so your research adds up to an investment case instead of a folder of spreadsheets.
Upload your carbon accounting and see which sources, sectors, and suppliers drive your Scope 3 footprint.
Match each emissions source to instruments across marketplaces and registries, then compare price, geography, quality, claims, and eligibility.
Check each instrument against the standards that apply, provision by provision, with the source text one click away.
