Reduction levers
Footprint is the easy part. These five levers are where the work sits. Each is ranked by tCO₂e reduction; cost and effort show the realism.
Measurement without action is decoration. The point of methodology depth isn't the number — it's that the number cleanly identifies which levers to pull, in which order.
Ranked levers
Switch venue to an all-rail-accessible site
↓ 6.2 tCO₂eThe biggest single lever — mode-shift comes from venue access, not from asking attendees to change behaviour.
Equivalent remote attendance for international travellers
↓ 5.4 tCO₂eMost of the international footprint is 18 people. Make remote attendance equivalent (not lesser) and the lever closes itself.
AM-only format
↓ 3.2 tCO₂eHalf the day removes lunch, halves heating + electricity, and tightens travel windows. Programme cost is real.
Booth materials reuse pool
↓ 0.8 tCO₂eA shared library of branded signage/lanyards across the Pawston event programme. Materials become an asset class, not consumables.
Reduction figures are illustrative for this demo. Real reduction modelling uses the same factor lockfile + σ engine as the headline number — the methodology page has the detail.
