The aims of all of the SOGE targets are for Government to: Lead by example Government must demonstrate leadership in the sustainable management of its estate and use its significant buying power to achieve a low carbon, more resource efficient public sector; and to reduce environmental impact Government must acknowledge the environmental impact of its activities and demonstrate how it is they are reducing this impact.
