When it comes to carbon from energy and the built environment, misdirected government measures (however good the intention) are now likely to do more harm than good. Eye-catching initiatives, if and when they fail, provide justification to cynics and people whose interests lie in maintaining the status quo. And more importantly the measures waste time and damage the chances of introducing more effective alternatives in future.
We’re seeing this now with the zero carbon targets. As the UKGBC recently found, the targets as they stand will be impossible to meet for up to 80% of new homes. The current zero carbon definition is a great idea very badly expressed.
