Nature-based removals via Natural Capital PartnersData confidence — high

Offsetting strategy focuses on nature-based carbon removal projects in preference to avoidance or renewable energy projects. Appointed Natural Capital Partners as preferred provider. First purchase offset 19,790 tCO2e of residual embodied carbon from 80 Charlotte Street via a VCS- and CCB-validated community reforestation project in Kenya/Uganda (~42,000 tCO2e annual reductions; 15M trees planted). Offsetting positioned as last option after all reductions exhausted.

100% REGO-backed electricity; RE100 member; green gas in pipelineData confidence — high

As an RE100 member, all purchased electricity comes from 100% REGO-backed renewable tariffs. Only 1% of gas supplies are currently certified renewable (Green Gas Certified); a green gas procurement strategy is being developed. On-site PV generated 70,930 kWh in 2020 (0.23% of electricity consumption). Investigating self-generation on the Scottish Estate and working with brokers to source from nominated renewable generators, acknowledging that REGOs alone do not demonstrate additionality.
