The Environment Agency has a free downloadable carbon calculator for the construction industry.
The Environment Agency says “This tool helps highlight where big carbon savings on specific construction projects can be made. It can also be used to calculate your total carbon footprint from construction and help reduce it.”
Using the carbon calculator has helped construction projects save hundreds of tonnes of carbon dioxide (CO2). For example, the Radcot Weir construction saved round 600 tonnes of CO2, through using a replacement for concrete, re-using old material and avoiding waste. There are case studies of construction projects that have used the carbon calculator on the Environment Agency website.
