This CIBSE approved CPD encapsulates the transition from traditional carbon-intensive practices to the necessity of Environmental Product Declarations (EPDs) in the construction industry. It highlights the industry's historical reliance on short-term perspectives and cost considerations versus sustainability, emphasising the imperative shift towards transparency, eco-credentials, and reduced environmental impact. It explains the significance of EPDs in promoting comparisons, green building principles, and considerations such as cradle-to-grave analysis and embodied carbon.
