3. The elephant in the Boardroom ! CARBON

7. 34% cut by 2020; 80% by 2050 5 year budgets; independent Committee; annual report to Parliament Extensive enabling powers Climate Change Act Climate Change Act November 2008 Climate Change Act November 2008

8. 2008 Budget Already have all new homes to be zero carbon by 2016 All new schools to be zero carbon by 2016 Ambition for all new public sector buildings to be zero carbon by 2018 Ambition for all new non-domestic buildings to be zero carbon by 2019

18. Sustainable Procurement…? “Sustainable Procurement is a process whereby organisations meet their needs for goods, services, works and utilities in a way that achieves value for money on a whole life basis in terms of generating benefits to society and the economy, whilst minimising damage to the environment”.
