Will this standard become regulated by government?

It is unlikely that this standard will be regulated to such a degree that compliance will be compulsory. However, as various aspects of logistics and operations and event impacts are regulated, it will mean that compliance with the standard is an easy route to compliance with regulations. (think Environment Agency and local government regulations for such things as sound, lighting, traffic, waste and localized pollution regulation). As an industry we need to keep an eye on regulations around CO2 emissions and reporting of those emissions. At some point in the future it is possible that our industry will be required to report emissions and to take action to reduce them. This however, is just another element of event logistics which is monitored and regulated.
