HIPS - a need for systems thinking?

Last week saw a delay in HIPS - the home improvement packs to be provided by home owners. I can't work out whether a HIP is designed to improve the home selling and purchasing process, make people more aware of energy management and carbon footprint or to provide more employment for those doing the certification that's needed. Or all of these and more? If giving benefit of the doubt I see the Government wrestling with issues of sustainability....though as much economic as environmental. But as they continue to climb down from it on grounds that were in some cases predicatable and others not, I see an intervention that has failed to take systemic factors into account. Can't help but think that this might be more about political point scoring and economic growth rather than sustainable development.
