K osmos values the natural areas where it does business, both land and sea, and strives to prevent or minimize potential adverse impacts on the environment. Our Health, Safety, and Environmental (HSE) management system, known as The Standard, is reviewed and updated as needed. The Standard sets clear expectations and performance measures that we use to plan and monitor our corporate, country, and project-level activities. The Standard is available on our website. Prior to seismic acquisition or drilling operations, Kosmos completes environmental and social impact assessments (ESIA) as standard practice. The process used satisfies International Finance Corporation (IFC) guidelines, as well as those reflected in the Equator Principles. ESIAs generally consist of the following key process elements: • Initial screening of the project and scoping of the assessment process • Examination of alternatives • Stakeholder identification (focusing on those directly affected) and gathering of environmental and social baseline data • Impact identification, prediction, and analysis • Generation of mitigation or management measures and actions • Significance of impacts and evaluation of residual impacts • Documentation of the assessment process Kosmos’ ESIAs may also include records of public consultation and supporting technical documentation. Conducted offshore, our seismic acquisition activities also provide unique insight into the presence of marine life, including marine mammals, sea turtles, and sea birds. Where possible, we share this data with scientists and local marine research institutes. In recent years, we have contributed data for papers on Clymene dolphins in the Eastern Tropical Atlantic, whale and dolphin occurrence offshore Ireland and São Tomé and Príncipe, and sea turtle populations offshore Morocco. In addition, Kosmos has also supported other marine biodiversity and conservation initiatives in Mauritania and São Tomé and Príncipe. We plan for an effective and timely response to emergencies that could impact personnel, the environment, local communities, or our assets. In 2018, we continued our regular program of conducting crisis simulation drills with internal and external stakeholders to help us improve our ability to respond in the unlikely event of an emergency. These simulations are created and Kosmos and the Environment XX XX 14 15 adapted to reflect the evolving nature of our business activities. Our local leadership teams and HSE advisors are mentored through these exercises to develop their ability to lead on the ground during an incident. In addition to training personnel, Kosmos carefully considers the technology and drilling equipment that it uses. Our Well Integrity Management System governs well design and how wells are drilled, completed, and tested. We believe in safe and efficient operations that are consistent with strong well governance procedures and internationally recommended best practices. We finished 2018 with a Total Recordable Incident Rate (TRIR) of 1.99 and a Lost Time Incident Rate (LTIR) of 0.5, against our global targets of less than 1.1 and 0.5, respectively. We had zero fines and zero spills. Our 2019 performance targets are a TRIR and LTIR of less than 1.1 and 0.5, respectively, zero spills, and zero fines/penalties. We aim to be an injury-free workplace no matter where in the world we operate and recognize that each individual needs to play a role in this effort – through safety vigilance, awareness of surroundings, and focusing on the task at hand. In 2018, we continued to require personal and occupational safety training for all employees to reinforce our safety culture. 4 BUSINESS PRINCIPLE São Tomé and Príncipe are rich in biodiversity, including many endemic species. In 2018, Kosmos initiated several social and environmental projects to ensure benefits reach both islands. As part of our Environmental and Social Impact Assessments, we evaluate potential effects on sea birds such as those photographed here in Mauritania’s Diawling National Park. KOSMOS VALUES THE NATURAL AREAS WHERE IT DOES BUSINESS, BOTH LAND AND SEA, AND STRIVES TO PREVENT OR MINIMIZE POTENTIAL ADVERSE IMPACTS ON THE ENVIRONMENT.
