Persefoni vs Vaayu

Persefoni provides software for organizations to measure and report carbon footprints, work on decarbonization, and manage sustainability disclosures. Its Pro and Advanced plans cover Scope 1, Scope 2, and all 15 Scope 3 categories. The Sustainability Report Builder guides disclosure work using qualitative responses and emissions data for frameworks including CSRD, ISSB, and CDP. Persefoni Copilot offers in-app carbon accounting support, while PersefoniAI can detect data anomalies; natural-language emission factor mapping is listed as coming soon. Integrations include Amazon Web Services, Concur, Expensify, Google Sheets, Navan, and utility providers. Advanced includes APIs and an Integration Hub for data ingestion. Persefoni describes the service as multi-tenant SaaS hosted on AWS, with encryption at rest using AES 256 and in transit using TLS 1.2 or above. The free Pro plan is limited to one user and excludes detailed GHG Metrics Reports. Advanced allows unlimited users, with pricing available by demo request. Personalized Concierge Support is a paid upgrade; all users can access the Help Center, guides, and tutorials.

Vaayu is web- and API-based carbon management software for retail brands and other businesses. It supports collaborative calculation, reduction, offsetting, and communication of company carbon footprints across Scopes 1, 2, and 3, including supply-chain emissions. The platform also provides product-level impact calculations and life-cycle assessments, and monitors 16 impact categories such as emissions, water, and waste. Vaayu says its Kria modeling engine uses AI and machine learning to automate activity-based life-cycle assessment data. Teams can model and track reduction scenarios at product and company level across materials, factories, transport, durability, logistics, and packaging. Reporting includes CSRD-relevant data and structured exports for CDP, FLAG, GRI, ISSB, and other frameworks. Customers can connect shop platforms and internal systems, use APIs, or import data with CSV/XLSX templates. Vaayu lists a free plan at free; its scope depends on the selected plan, and availability is not promised. Paid pricing is available on request. Vaayu says its security practices are SOC 2-compliant and its corporate footprint methodology is independently reviewed and recertified annually by TÜV Rheinland.
