What is the circular economy in construction?

A system minimising waste by reusing, recycling, and regenerating materials

An economic model in which construction firms trade only within their own region, never outside it

A building layout designed around a large central atrium, circular in plan

A funding model where profits, rather than being distributed, are reinvested in the same project

What is a carbon footprint?

The total greenhouse gas emissions caused by an individual, organisation, or product

The physical land area taken up by a carbon capture and storage facility, including its plant

The amount of carbon permanently stored in the materials, once a building has been constructed

The annual carbon tax payable to government, charged on a large organisation's emissions

- AA funding model where profits, rather than being distributed, are reinvested in the same project
- BA building layout designed around a large central atrium, circular in plan
- CA system minimising waste by reusing, recycling, and regenerating materials
- DAn economic model in which construction firms trade only within their own region, never outside it
