When carbon data becomes a requirement not a choice.

Many growing companies are now being asked to provide carbon or ESG data as part of supplier questionnaires, tenders, or procurement processes.

For teams without in-house sustainability expertise, this often leads to confusion, delays, or rushed responses that don’t feel credible.

CarbonSquare exists to remove that uncertainty.

→Missing or unclear responses can delay deals or disqualify bids

→Consultant-led projects are often slow, expensive, and over-scoped
