How We Estimate Event Carbon Footprints

Our estimates follow the GHG Protocol methodology, covering Scope 1 (direct venue emissions), Scope 2 (electricity & heating), and Scope 3 (catering, waste, materials). We calculate approximately 10.2 kg CO2e per delegate per day for venue operations in Slough.

Key factors include: venue energy consumption (~4.2 kg), catering & food service (~3.5 kg), waste & materials (~1.5 kg), and water & facilities (~1.0 kg). Delegate travel is excluded as it varies significantly — however, choosing a Slough venue with strong public transport links (such as SL1) can reduce travel emissions by up to 40%.

Methodology based on GHG Protocol Corporate Standard. Figures are UK averages for conference/event venues. Actual emissions depend on venue size, energy source, catering choices, and season. We recommend venues with ISO 20121 certification for the lowest environmental impact.
