Transparency and traceability in chemical value chains
A Nature paper argues for harmonized accounting, digital verification and collaborative governance. Carbon3 provides exactly that.

Complex supply chains pose an enormous challenge for decarbonizing the chemical industry in the face of pressure to move towards net-zero emissions. This paper in Nature Magazine argues that transparency, traceability and end-to-end governance can incentivize companies to invest in verified emissions reductions within their own value chains.
"The chemical industry can overcome these obstacles with three interconnected solutions (see figure):
- harmonized and transparent accounting frameworks,
- digital systems to track and verify reductions,
- collaborative governance and capacity building across the value chain."
At Carbon3 we're already enabling this vision. On our registry, project developers issue inset credits from real Scope 3 projects once an independent verifier has confirmed the reductions. The registry acts as a co-financing instrument, with high additionality, no scope 1-3 double-counting, and facilitates cost & benefit trading/sharing across value chains.
Chemical companies: Invest in your supply chain's future with tamper-evident audits and dynamic allocation. Align with EU CBAM, US IRA, and Paris goals today.

REDD+ credits were oversold, but most projects cut deforestation
A peer-reviewed study of 44 projects found credits oversold by a factor of more than ten, while four in five projects genuinely reduced forest loss.
