Yes, the Product Impact Solution provides granular results even with minimal primary data. While more primary data improves accuracy, our system ensures quality results regardless of data availability. All of Vaayu’s all-in-one LCA tools integrate seamlessly for the smooth transition of data.

What data is required to use Vaayu’s product carbon footprint calculator?

The minimum requirement is product type, but additional data like material composition, percentages, weights, and supplier energy usage can enhance the accuracy of calculations.

Where does Vaayu source secondary data for its product carbon footprints?

Our proprietary impact modeling engine and database, Kria, combines industry-standard sources, research papers and scientific studies, curated by our expert in-house LCA team to fill data gaps effectively.

Can we view the assumptions and data sources used in the product carbon footprint calculations?

Yes, the platform provides full transparency into assumptions and data sources for each calculation, as well as Accuracy Scores, so you always have a clear understanding of your footprint.

Can we use our own emission factors as part of the product carbon footprint calculations?

Absolutely. Vaayu’s platform allows you to apply your own emission factors to ensure calculations align with your specific requirements.

Does Vaayu account even for innovative or circular materials and processes?

Yes, our database includes detailed information on new and innovative materials and processes for accurate and up-to-date calculations.

What is the timeline for receiving our product carbon footprints?

Once we receive the necessary data, the calculation process typically takes 2-4 weeks, depending on the complexity of your needs and requirements for your personalized dashboard.

Do the product carbon footprint calculations comply with PEF standards?

While the Product Environmental Footprint method (PEF) is still evolving, our methodology and databases are already adaptable, accounting for all 16 of PEF’s required impact categories, ensuring compliance with the current PEF version and readiness for future updates.

At Vaayu, our team combines deep expertise in LCA, retail, sustainability and compliance to deliver a solution that meets the complex demands of lowering product impact across the entire life cycle.
