Our Island's homes, offices and buildings are mostly made of concrete, making concrete the second most used material in Jersey after drinking water.
Local trends such as uncontrolled population growth and urbanisation are colliding to increase the unprecedented growth of buildings in Jersey and the increased use of concrete. If concrete was bread, cement would be the flour needed to make the bread. Cement is mined limestone - heated in a rotary kiln split in two halves - clinker and CO2 the two products; cement production alone is responsible for 5-8% of all global emissions.
Options like hempcrete for all above gound construction should be considered.
Concrete that has captured carbon should be preferred choice for subteranial designs.
All planning applications should consist of a residual and energy carbon emissions statement.
Why the contribution is important
Keeping CO2 emissions within the 2 - 1.5 target, using concreate as we do today is not achievable.
Jersey has to brake its link between the use of concrete and CO2 emissions.
It will be impossible to meet out NET Zero ambition while concrete remains the favoured choice for buildings.
