Our Call to Action

The AECB recognises that the acute environmental and social challenges that humankind has created, require us to face frightening and inconvenient truths. The building industry has great responsibilities, faces huge difficulties, yet also has many opportunities. It can make a positive, long-term contribution to society. Within the AECB, we need to maintain a relentless and informed optimism in the face of these challenges. We need to empower people in the industry to collaborate and undertake transformational action to make building practice radically more sustainable – locally, nationally and internationally.
