1. Scope & boundaries. This assessment reports greenhouse-gas (GHG) emissions for the product life-cycle stages explicitly declared in the report. Unless stated otherwise, the results include emissions from raw-material extraction through conversion/manufacturing (cradle → gate). Downstream stages such as distribution, use-phase, and end-of-life are excluded unless explicitly included in the output. Users must confirm desired system boundaries for any custom report.

2. Data quality & uncertainty. Results reflect the quality of input data and assumptions (primary supplier data, secondary databases, proxies). This tool provides indicative estimates for internal comparison and decision-support. It is not a verified or audited product carbon declaration unless accompanied by third-party verification. Reported values may carry significant uncertainty; sensitivity analysis is recommended for material contributors.

3. Formulation assumptions. Product footprints are calculated from the stated bill-of-materials and the model assumptions provided. Where primary data are unavailable, the tool uses weighted-average proxy assumptions supplied by the user or default values stated in the methodology. Example: “Formulation assumes 30% new rubber-plantation sourcing and 70% existing plantation sourcing” — this is an assumed sourcing split and must be changed if verified supplier data are available.

4. Reference case and scaling. The underlying LCA was originally performed on a base case of 26% Verdura loading. All other data points in this tool are derived by proportional scaling from that base case. If your formulation departs materially from the base case (different loadings, additional materials, or different processing), results may not scale linearly and you should request a full reassessment.

5. Biogenic carbon. Biogenic carbon (CO₂ uptake and release associated with biomass feedstocks) was not quantified or accounted for in this assessment, unless explicitly shown. Biogenic carbon accounting involves alternative methodological choices and can materially affect results; if you require inclusion, specify the accounting approach (e.g., stock accounting, “-1/+1”, or other recognized method) so it can be applied and documented.

6. Use of the results & claim limitations. This score/estimate is not a guarantee of environmental impact nor an authorization to make absolute marketing claims (for example “carbon neutral” or “climate positive”) without appropriate substantiation, third-party verification, and compliance with applicable jurisdictional rules. Avoid any public claims that rely solely on unverified offsets; many regulators require clear evidence and may restrict offset-dependent claims.

7. Recommended disclosure. When publishing results, disclose: (a) the standard/method used (e.g., GHG Protocol Product Standard, ISO 14067), (b) system boundaries and excluded stages, (c) treatment of biogenic carbon, (d) data sources and vintage, (e) base case/formulation details, and (f) uncertainty and whether independent verification was performed.

8. Legal & regulatory note. Regulatory requirements for environmental claims differ by market and can change rapidly. The tool operator or user is responsible for ensuring all public claims comply with local laws, consumer-protection guidance, and industry standards.
