11:12 Caroline Lucas (Brighton, Pavilion) (Green)
T5. Will the Secretary of State join me in congratulating Brighton and Hove city council on its resolution to become a One Planet council, which means, for example, that it will be run using sustainable procurement policies, and renewable energy and biodiversity practices? Will she commit to adopting One Planet principles as a step towards keeping sustainability in all policy making?

11:13 Mrs Spelman
I am happy to extend a hearty congratulation to the hon. Lady’s council, and I understand that the Isle of Wight is about to declare itself an eco-council, which shows the important role that local authorities can play. She will also know that the UK is playing a leading part in the preparations for the Rio+20 summit—the 20-year anniversary of the original Earth summit—where we will strongly advocate the need to put growth on to a more sustainable footing. We have also given strong support to the Colombian proposal for sustainable development goals.
