Forest 4.0 Balancer

The Forest 4.0 Balancer project is set to explore relationships between forests, carbon footprints and construction.

Based on the embodied emissions of the City of London’s Leadenhall Building (92,210 metric tonnes of C02), Annular invites anyone involved in sustainability, timber, building and forests to speculate on what they could do construction-wise with 92,210 metric tonnes, given the opportunity.

Additional Annular sections to be added. Watch this space.
