We instill a culture of operational excellence (OE) that places the highest priority on the safety and health of our workforce and on the protection of communities, the environment and our assets. We are committed to continually improving our environmental performance and reducing the potential impacts of our operations through the implementation of our Operational Excellence Management System.
The Environment is one of the six focus areas of our Operational Excellence Management System (OEMS), which puts into action our Chevron Way value to protect people and the environment. The OE objective for the Environment Focus Area establishes the priority for our global operations to assess and manage their significant environmental risks across the life of our assets.
ES corporate process
To drive consistency in meeting our Environment Focus Area expectations, we have an Environmental Stewardship (ES) process. The ES process directs our businesses to create an inventory of how their activities interact with the environment. These environmental aspects and their related potential impacts are then used to identify, assess and prioritize environmental risk and improvement opportunities.
ESHIA corporate process
In addition to our ES process, we have an Environmental, Social and Health Impact Assessment (ESHIA) process. Our ESHIA process is designed to consistently identify and address potentially significant project-related environmental, social and health impacts. Since its inception in 2007, we have used our ESHIA process in the planning and implementation for capital projects worldwide.
Chevron has nine environmental standards, which apply a consistent level of rigor in managing the environmental aspects of our business. The corporate standards include Third-Party Waste Stewardship, Site Residual Impact Management and Health, Environment and Safety Property Transfer.
We also have six Upstream-specific environmental performance standards (EPSs) for managing air emissions, flaring and venting, natural resources (including water and land use), offshore drilling fluids and cuttings, produced water and waste management. These EPSs are applied across our Upstream business and capital projects and provide uniform standards and operating practices.
four environmental principles
We have four environmental principles that define our commitment to doing business in an environmentally responsible manner, as we believe that protecting the environment is compatible with providing energy. These principles are implemented across the life of our assets.
- Include the environment in decision making.
We all make decisions that may affect the environment. From our everyday actions to our major capital investments, we make better decisions when we consider the environment.
- Reduce our environmental footprint.
We use our business processes to identify and manage risks to the environment and reduce potential environmental impacts throughout the life of our assets.
We apply our Tenets of Operation and improve reliability and process safety to prevent accidental releases.
We work to decommission, remediate and reclaim operating and legacy sites with the aim of beneficial reuse.
seven environmental aspects
Consistent with ISO (International Organization for Standardization) 14001, we defined seven types of environmental activities, or Corporate Core Environmental Aspects, that we address:
Decommissioning, remediation, reclamation and/or abandonment of sites and facilities
learn more about EMC
Management of all types of solid waste regardless of hazardous classification
Unplanned releases including petroleum and chemical spills and releases of hazardous vapors
learn more about preparing for potential emergencies
Management of all types of domestic and process wastewater, including produced water
Emissions of air pollutants, including criteria pollutants (NOX, SOX and particulate matter), volatile organic compounds and hazardous air pollutants
more about air emissions
measuring our performance
We measure our environmental performance, which enables us to make informed business decisions around protection of the environment. In addition, we are committed to annually reporting performance data on the 11 environmental indicators in the 2015 IPIECA/API/IOGP* Oil and gas industry guidance on voluntary sustainability reporting.
We use our environmental data to understand our performance and help identify potential areas of improvement. We have invested in processes, systems and training to meet our objective of maintaining high-quality environmental data. For example, we conduct detailed onsite and desktop peer reviews of local data collection processes, with a focus on operations that contribute the most to our enterprisewide data. These peer reviews verify that all sources have been accounted for and reported in accordance with Chevron’s Operational Excellence Data Reporting Standard. Our peer review process and independent reviews by third parties continue to provide ongoing assurance of our data quality to enable informed business decisions.
