Frequently asked questions
Everything decision-makers ask before kicking off a CSRD programme.
Most mid-market teams produce a first defensible carbon footprint in 2–4 weeks, and a full CSRD/ESRS narrative within one reporting cycle. The pre-loaded ESRS catalogue, emission factors, and CSV templates remove most of the setup work.
No. The guided workflow walks you through each datapoint, with frameworks and emission factors pre-loaded. The AI co-pilot suggests material topics, parses uploaded evidence, and drafts narrative text — your team validates and signs off.
GHG Protocol (Scope 1/2/3), CSRD/ESRS (E1–E5, S1–S4, G1), ISO 14064, and GRI. The report engine maps your data to disclosure codes automatically and generates per-framework outputs.
Invite suppliers via tokenised links — no logins required. They submit Scope 1/2/3 figures and ISO/SBTi flags, you allocate by revenue share, and the dashboard tracks the % of Scope 3 backed by primary data over time.
Every datapoint is timestamped, attributed to a user, linked to evidence files, and traceable to the emission factor and source. The XLSX export gives auditors a clean working paper; the PDF report is board-ready.
Each company workspace is isolated with row-level security in the database. Members are scoped per workspace; nothing crosses tenant boundaries. EU-hosted infrastructure.
Yes — every pillar has a CSV template. Upload HR exports, utility bills, travel reports, or fleet logs. The import preview validates units and emission-factor matches before committing.
