2015 Corporate Citizenship Report

External standards and OIMS OIMS addresses the management of SSH&E risks at our operations worldwide. OIMS conforms to recognized safety, security, health and environmental standards, such as the International Organization for Standardization (ISO), the Occupational Health and Safety Assessment Series for occupational health and safety management systems (OHSAS) and the American Chemistry Council (ACC) Responsible Care® requirements. In 2013, Lloyd’s Register Quality Assurance Inc. (LRQA) reviewed our ongoing performance and attested that OIMS is consistent with the intent and meets the requirements of the environmental management system ISO 14001:2004 and the occupational health and safety management system

Since the inception of OIMS in the early 1990s, we have significantly reduced our lost-time incident rates, demonstrated a remarkable decline in marine spills and contributed to continuing emission reductions. OIMS establishes a common framework for addressing SSH&E risk across all aspects of our operations, including our supply chain. At the global corporate level, the OIMS framework is built around 11 elements, as illustrated below, each covering a key aspect of risk across the breadth of ExxonMobil’s operations. Each element is comprised of a number of expectations, 65 in all, that provide greater detail. OIMS element 1 — management leadership, commitment and accountability — outlines the expectations of managers as they lead their organization through OIMS. OIMS element 11, operations integrity assessment and improvement, describes the requirements associated with how each operating unit evaluates the extent to which it is meeting the expectations of OIMS. These two elements are often referred to as the “bookends” of OIMS, with element 1 being the “driver” and element 11 providing the feedback mechanism to ensure continuous improvement. Elements 2 through 10 address the operational, day-to-day aspects of OIMS, such as risk management, facilities design and construction, and personnel and training. All operating organizations are required to conform to the expectations described in OIMS. In order for the 11 elements and 65 expectations to be consistent and relevant across ExxonMobil’s diverse operational portfolio, our Upstream, Downstream and Chemical businesses have established detailed OIMS guidelines. These guidelines describe how each business unit addresses the 65 corporate expectations relevant to that business unit’s operations. Additionally, management is responsible for ensuring that management systems satisfying the framework are in place at each operating unit. OIMS includes a systematic, disciplined approach to measure progress and track accountability across business lines, facilities and projects. To drive continuous improvement, we evaluate opportunities to improve the OIMS framework by periodically reviewing and upgrading it.

OHSAS 18001:2007. This attestation is valid for three years, and our next attestation is scheduled to take place in 2016.

Responsible Care® is the chemical industry’s comprehensive health, safety, security and environmental performance improvement initiative. Lloyd’s Register Quality Assurance Inc. also certifies OIMS conformance to Responsible Care Management System® Technical Specification RC101.04 per ACC’s requirements. Systems within OIMS are linked to the relevant Responsible Care Management System® expectations. This approach allows ExxonMobil to run its business through one SSH&E management system, OIMS, and align with local and global standards.
