environmental risk management

Protecting the environment takes commitment, effective processes, leading technologies and dedicated people. Our Operational Excellence Management System (OEMS) recognizes the potential impact of many factors on the environment. This recognition is operationalized through our Environment Focus Area Strategy and Environment Risk Management Process (ERMP).

environment focus area

In 2021 we deployed our EFA Strategy, which provides an integrated vision for achieving our goal of protecting the environment while providing affordable and reliable energy. The strategy helps us clarify our environmental expectations, including:

accidental release icon

preventing and mitigating the consequences of accidental releases

air emissions icon

reducing air emissions, including GHGs

natural resources biodiversity icon

conserving and protecting water and biodiversity

wastewater icon

managing waste and wastewater

energy efficiency renewable

conserving energy

environment icon

retiring idle assets and reclaiming sites with residual environmental impacts

At Chevron, I’ve had the opportunity to help develop a more holistic waste management strategy, recognizing that waste is intertwined with other factors that can impact the environment. In this capacity, I identified opportunities to optimize business units’ waste reporting practices and trained data reporters across the enterprise to align with our data reporting expectations. I’m proud of my role in improving the quality of our waste data because a robust data set enables us to make better decisions on how to optimize our waste management approach.

I’ve also served as a technical resource across the company, helping solve complex waste challenges and share best practices. I’ve helped develop new methods to increase waste recovery that can mitigate risk, reduce cost and reduce our environmental footprint. For example, I managed a project that developed a new approach to removing surface scales from scrap metal using a fiber laser beam delivery system. This approach has the potential to increase recycling options for scrap metal and reduce the creation of secondary waste streams when compared with other methods.

I’m encouraged by Chevron’s approach to waste management through our implementation of the Third-Party Waste Stewardship standard that establishes a standardized approach for how we select and set expectations for third-party-owned facilities that handle waste generated from Chevron operations. This process demonstrates how we work to influence the companies with whom we collaborate and illustrates Chevron’s commitment to our core values, which include protection of human health, safety and the environment.

environment risk management process

In 2021 we also deployed ERMP, a framework to identify, assess, mitigate and manage environmental risks, including those involving community health and social risks, across the lifecycle of an asset. The process is designed to be fit-for-purpose so that it can be applied to activities with a broad range of complexity, including large projects and ongoing operations. This process seeks to go above and beyond local regulatory requirements, to strengthen our safeguards and apply lessons learned across Chevron.

digital solutions

Future environmental solutions rely on a strong foundation of standardized workflows, data automation, analytics and process integration. First deployed in 2020 at the Richmond Refinery, our Integrated Waste Solution (IWS) creates a digital interface between the personnel managing operations that generate waste and the environmental personnel responsible for waste handling and management. The solution automates and standardizes waste requests, approvals, tracking and payment, which saves time and puts in place safeguards. Through the development of IWS and related technologies, we seek to streamline our reporting, reduce waste management storage time and align with our Third-Party Waste Stewardship standard designed to mitigate waste disposal risks.


Innovation plays a key role in supporting our efforts to assure effectiveness of safeguards and mitigate environmental risks.

the chevron technical center

CTC bridges the gap between business unit needs and externally developed emerging technology solutions such as technologies to generate biodiversity baselines, uninhabited aerial systems for environmental monitoring, real-time measurement tools for site assessment, and lower carbon solutions for environmental remediation.

the chevron richmond technology center

Through research and development conducted in the CRTC, we piloted the use of an infrared gun to rapidly measure total petroleum hydrocarbons in soil and drill cuttings at sites in California, Colorado and Michigan and deployed at full scale a similar commercially available device within our IndoAsia business unit. The technology eliminates the need to use any chemicals for sample extraction and analysis, and when used at scale, it enables faster turnaround and improved decision making in the field, which has resulted in notable cost savings.


Another innovation is Hottpad, a cost-efficient remediation technology that has a lower carbon intensity than traditional thermal methods. First used at the Chevron Batangas terminal in the Philippines, Hottpad has been piloted within the San Joaquin Valley business unit in California, with a full-scale deployment underway for Wafra Joint Operations in the Partitioned Zone between Saudi Arabia and Kuwait.

growing workforce capability

In 2021, 16 business units and 11 other stakeholder teams user-tested the new environment and stakeholder risk management tool, which collects baseline data for developing business unit risk profiles and assessing enterprise risk. We also hosted trainings to build competency with our qualified environmental facilitators, and these trainings included risk assessment workshops in Bangladesh and the Mid-Continent business unit.

working to reduce plastic waste in the environment

Plastics are an essential part of modern life, and plastic waste should not end up in unintended places in the environment like rivers and oceans. We are taking steps to address plastic waste and support a circular economy in which post-use plastic is recycled, reused or repurposed.
