Co-founder and Director
"We regularly engage Giero Consulting to support GHG accounting work, notably where we need someone who can navigate between technical methodology and practical application. This is particularly critical around Scope 3 and avoided emissions frameworks. She always delivers.
The Founder, Jessica and her team, have a rare ability to make complex concepts understandable to clients who are still building their literacy in this space, without losing rigour in the process. For any organisation navigating emissions reporting, regulatory alignment, or building out a credible decarbonisation strategy, Giero Consulting is exactly the expert you want on your team."
Director of Engagement
We worked with Jessica on an ESG report we were doing for one of our clients. Her professionalism and expertise proved extremely beneficial for the entire project. Jessica's insights into the sector helped the client make some important decisions on how to move forward with their reporting.
Working with Jessica is a pleasure as her professionalism, expertise and genuinely collaborative approach provides concrete support to any communications efforts.
