I can give this assurance to the hon. Gentleman: the planning reforms that we intend to bring forward in the weeks ahead will not row back on any of our commitments to the environment. This Government want to bring forward homes that are truly fit for the future. We do not want to see homes being built in the years ahead that will need to be retrofitted at huge expense either to the state or to individuals in time. We want to ensure that we meet our obligations to the environment, to biodiversity and to the climate change challenge, and that is exactly what the proposals that I intend to publish later this month, or at the beginning of August, will do.
