Environmental Product Declarations
The Environmental Product Declaration (EPD) for clay brick demonstrates that over the product’s whole lifecycle - including construction, in-use phase as well as end-of-life of a building - overall carbon emissions per year of service life are low. At their end-of-life, products can also be re-used and recycled.
Whilst EPDs help specifiers advance sustainability goals, the study period for a building’s life is only 60 years, which is far less than the typical service life of 150 years, and only 1% of the age of the oldest fired clay bricks made 7500 years ago and still in use today! In other words, calculating the carbon cost over too short a lifespan penalises more durable products such as clay brick that are less carbon intensive over the full lifespan and beyond.
