We measure Scope 1 direct emissions relating to office, sales, development site activities and travel diesel combustion on our sites and business travel from company leased vehicles. We measure Scope 2 indirect emissions for purchased electricity and heat for all our sites and offices. Our Head Office in Waltham Cross switched to a green tariff supply from November 2018. We measure Scope 3 other indirect emissions relating to business travel by road and air. We are now disclosing our sustainability data against the calendar year, in line with CBRE (parent company) reporting requirements.
