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.
