The Group's water usage during 2011 saw a large increase compared with 2010, primarily due to water injection from the FPSO into the Jubilee field reservoir. The Jubilee field is offshore Ghana and Group water usage was therefore 99% seawater and 1% fresh water for 2011.Greenhouse gas (GHG) emissions for 2011 accounted for around 93% of Group total emissions. GHG emissions from the FPSO were the most significant contributor to the overall increase in GHG emissions for Tullow during the year.Tonnes CH4 as CO2 equivalent is calculated as tonnes CH4 x 21, where 21 is the conversion factor used to give methane in terms of CO2e.CO2e figures have not been assured by Deloitte, however figures for CO2 and CH4 emissions have been assured.Tullow has started recording waste data in 2011. West & North Africa accounted for 10% of waste produced during 2011, with operations in Ghana contributing almost all of this figure.West & North AfricaHOW WE PERFORMED IN 2011Local employeesLocal employees 88% Expatriate employees 12% 88%Social enterprise expenditure$5 MILLIONWest & North Africa 43% Rest of group 57% Greenhouse gas emissions1,285,901 TONNES0250,000500,000750,0001,000,0001,250,0001011259,4961,285,901CO2CH4 as CO2eWaste produced3,199 tonnes West & North Africa 10% Rest of Group 90% At the end of 2011, local employees and contractors in Accra and Takoradi numbered 210 in total.The single largest project in our social enterprise programme in 2011 was the Tullow Group Scholarship Scheme pilot phase, which was delivered in Ghana and represented $1.5 million of the total Group social enterprise spend. In 2012 the Scheme is being rolled-out in several other countries in the region.$46.9m was spent with local suppliers in Ghana during 2011. The decrease relates to the level and nature of our activities during a given year. During 2010 we built towards First Oil from the Jubilee field, requiring intense activity. We expect spend on local suppliers to increase again with forthcoming activities in Ghana.

LISTENING AND RESPONDING TO OUR STAKEHOLDERSGrievance management is an essential part of community engagement and support. In Ghana, grievances are received, recorded and reported internally to the IFC and the Ghana Environmental Protection Agency (EPA). Issues gathered through this process are discussed and investigated with the relevant Tullow functions (EHS, Operations and HR, for example) with the goal of resolving and reporting back to the respective source of each grievance. This robust process has involved the investigation of health and environmental concerns in fishing communities, perceived under-employment from within the Western Region, and requests for educational support. While not every grievance can be resolved, or is necessarily the responsibility of Tullow to manage, the process and detail required to understand each concern underpins our community work and strengthens our social licence to operate.www.tullowoil.com31
