About us
Who we are
The GBTS team were formerly the carbon claim verification experts of Green Box Thinking. That was the leading specialist carbon management consultant to the UK construction industry. We became a fully independent business during 2024.
Independence
We explained our role and client base on our home page. One reason we stick to a single specialism is verifiers like us must be independent. This means our other roles in relation to the buildings whose footprints we verify can only be very limited.
That way, we don’t effectively end up marking our own homework. We can’t, for example, make detailed calculations for you or tell you how to operate in depth over a project on which we’re engaged.
But working with us is still very much a team effort. You may lack ideal evidence, such as an environmental product declaration, which usually contains the most current carbon factor details about an item, for example. If so, we’ll gladly advise you on feasible substitutes, which could include documents such as manufacturer provided data and industry-average data for example.

The verification journey
Our service is not the end of a process. Verification is an ongoing activity on your journey to net zero.
Carbon claims are to be verified on an annual basis to show how emission reduction strategies are working, or where not, corrective actions can be implemented.
