How our emissions are calculated Positive Planet has calculated Havwoods’ greenhouse gas (GHG) emissions in line with the GHG Protocol, the globally recognised standard for carbon reporting. Emissions are categorised into Scope 1 (direct), Scope 2 (energy-related) and upstream Scope 3 (indirect) emissions. Results are reported in tonnes of carbon dioxide equivalent (tCO₂e), which standardises the impact of seven key greenhouse gases. The diagram in this section of the Report helps to visualise where these emissions come from and how they fall within the scopes. Calculations are based on data provided by Havwoods applied to UK Government issued emission factors, with spend data adjusted for inflation where needed. Where available activity-based data (e.g. energy consumption/distance travelled) has been prioritised; otherwise, a spend-based approach has been applied. Data reported to Positive Planet has undergone a high-level review but has not been completely verified to source. In devising a carbon reduction plan with the goal of achieving Net Zero, it is critical that we first understand where our emissions come from. To support this, we have partnered with Positive Planet to measure our emissions.
