Journey to zero carbon education buildings George Martin Head of Sustainable Development Willmott Dixon Member Zero Carbon Task Force
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
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
