ESG data collection software: how to collect ESG data without chasing spreadsheets
ESG data collection software gathers the energy, emissions, workforce and governance data a sustainability report needs from the people and systems that hold it. Good tools request data from named owners, chase them, read invoices and bills, pull from integrations, and keep a source on every number so the final report is audit-ready.
CDP reporting explained: how scoring works and why the data is the hard part
CDP reporting means answering CDP's annual environmental questionnaire, usually because an investor or a large customer asked you to. Responses are scored from D- to A across four levels. In the 2026 cycle the scoring deadline was 16 September, and final responses close in the week commencing 26 October.

Is Ella a good Sweep alternative?
Yes. Ella is a strong Sweep alternative for sustainability teams that want to be live quickly without a consultancy-led roll-out, want the data gathered for them, and need EcoVadis, SECR and VSME as well as carbon and CDP.
Which is easier to use, Ella or Sweep?
Ella is built to be the more guided option. It sets your boundaries, builds your data checklist, collects the data from colleagues and suppliers and drafts the outputs, so your team reviews rather than assembles. Sweep is a powerful data platform that larger companies often implement with a consulting partner.
How much does Sweep cost?
Sweep does not publish prices. You request a demo and receive a quote.
How much does Ella cost?

Does Sweep help with EcoVadis?
Sweep's website does not mention EcoVadis. Ella has a dedicated EcoVadis module that reads your scorecard, finds the gaps and drafts the fixes.
Can Ella collect ESG data from colleagues and suppliers?

Can I switch from Sweep to Ella?
Yes. Export your existing activity data and reports, drop them into Ella and it maps them to your reporting periods. Most teams run both side by side for one reporting cycle to check the numbers match.
