What ESG metrics does this calculator measure?
We measure carbon footprint (Scope 1-3 emissions), water usage, recyclability score, renewable material content, chemical safety (PFAS-free, BPA-free), biodegradability, and circular economy readiness. Results are benchmarked against SASB and GRI standards.
How accurate is the carbon footprint calculation?
Our model uses life cycle assessment (LCA) databases from ecoinvent 3.9 and IPCC AR6 emission factors, achieving ±15% accuracy for common packaging materials. For high-precision audits, we recommend third-party LCA certification.
Can I compare different packaging alternatives?
Yes! You can run side-by-side comparisons (e.g., virgin PET vs. rPET vs. bagasse) and see which option has the lowest environmental impact while meeting your performance requirements.
Does this include Scope 3 emissions?
Yes. We calculate Scope 1 (direct manufacturing), Scope 2 (energy), and Scope 3 (raw materials, transport, end-of-life) emissions following the GHG Protocol Corporate Value Chain Standard.
Is this tool compliant with EU regulations?
Our calculator aligns with EU Packaging and Packaging Waste Regulation (PPWR), EU Green Deal targets, and upcoming Digital Product Passport (DPP) requirements. Results can be exported for CSRD reporting.
