The challenge

Reporting that couldn’t stand up to external assurance

The company’s business travel reporting was based on average-based methodologies such as DEFRA, which lacked the granularity and defensibility needed for external assurance.

The annual assurance process was also lengthy, and threatened to become a time sink for the sustainability team, drawing attention away from other sustainability initiatives.

Deep-dive comparison of methodologies

Thrust Carbon compared the client’s existing average-based methodology, DEFRA, with more granular approaches such as ICAO. This helped the company understand the implications of each, and select the most appropriate for its reporting needs.

02
Moving to Thrust Carbon’s ISO 14083-assured methodologies

The company moved from average-based methodologies to Thrust Carbon’s ISO 14083-assured methodologies. ISO 14083 makes business travel carbon calculations clear, understandable, and repeatable, and is backed by the EU.

Calculations became highly accurate, giving the company a defensible foundation for its reporting and its third-party assurance.

03
Access to assurance-specific tools

Through Thrust Carbon’s Compliance Suite, the client gained detailed methodology documentation, complete calculation transparency, and the Assurance Admin role: ring-fenced permissions to dive deep into the data behind every calculation. Together, these made for a smooth assurance process and saved hours of work.

Well, in light of seeing all this data available, we’ll hold any methodology questions. We should be able to find the answers ourselves.
