Good communication, flexible schedule and delivered exactly what was agreed and on time. Would work with her again!
Whenever you hire consultants you worry whether they'll be as motivated or skilled as your team. Every Leafr consultant has been so impressive. We spoke to several sustainability agencies and this has been far better value.

Assurance readiness
Companies in scope for CSRD, UK SDS, and other incoming regulation need to move from zero to audit-ready reporting, often without the internal capacity to do so. Our consultants run double materiality assessments, build the reporting architecture to support ongoing compliance, close data gaps across the value chain, and map obligations across multiple jurisdictions. They prepare your disclosures for limited and reasonable assurance, and build the internal processes that make next year easier than this one.

Sometimes the gap is not expertise but capacity and seniority. We place fractional CSOs, interim sustainability directors, and senior project leads who embed in your team, take ownership of delivery, build internal capability, and maintain momentum through transitions, restructures, or peak reporting periods. They bring the experience of having led sustainability programmes at scale, without the commitment of a permanent hire.
