Mr. Pat Barry:

The energy performance of buildings directive requires us to measure the embodied carbon of buildings by 2028 - just measure it - and then to introduce targets by 2030. We suggest we should accelerate that and get targets in place a little earlier because we need to signal to the industry there are targets and it can start planning to meet them, rather than just measurements. Once you measure, there is a tendency to reduce, and that is very helpful in 2028, but it would be very useful to introduce targets then also. We are required to set out a roadmap of targets by 2027 in any case, so it would be useful to incorporate those into the revised regulations in 2028.
