Blog / ESG Bristol Building Insulation Programme 5 January 2022 — by Barry Bassett The Bristol facility is being fully insulated and fitted with triple-glazed roof lights.We don’t know exactly how much CO2e this will save yet, but if it saves 33% of natural gas emissions, it could save nearly 2 tonnes of CO2e.In building projects like this, VMI require that builders only use timber from sustainable (managed) forests and when tendering for the work contractors must show their sustainability protocols.
