Equivalent work is also expected to start in 2014 on a range of finished wood products, including doors, windows, shutters, curtain-walling and flooring (Anderson, 2014). Efforts are being made to assist with the development of EPDs at the national level by compiling comprehensive LCA data for timber and wood products, for example through the United Kingdom's Wood First Plus Initiative. These EPDs are independently verified by Underwriters Laboratories to ensure that EPDs conform to ISO 14025 requirements.
