For me that's a challenging question. I think in the short term we need an evidence-based policy to guide definitions of sustainability, definitions of impacts, assessment of impacts. So I would say it's strengthening and concentrating regulation and impact assessment such that it is efficient but is thorough, such that efficiency isn't balanced off against full scientific inquiry into impacts.
I am certain there are other witnesses who would have more informed views on this, but I think industry would agree that in the long term, what's good for the environment is good for long-term job prospects as well. Sustainability economically and sustainability environmentally are perfectly compatible.
