environment

we conduct our business in a socially and environmentally responsible manner, respecting the law and universal human rights to benefit the communities where we work

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.

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.

  1. 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.
  2. 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.
  3. Operate responsibly.
    We apply our Tenets of Operation and improve reliability and process safety to prevent accidental releases.
  4. Steward our sites.
    We work to decommission, remediate and reclaim operating and legacy sites with the aim of beneficial reuse.

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 utilize 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.
