environmental
management

At Chevron, one of our core priorities and Chevron Way values, is to help protect the environment. We do this through responsible design, development, operations and retirement of assets.

The Gorgon Project is located on Barrow Island, Western Australia

our approach to
biodiversity

Biodiversity refers to the variety of life on earth and includes ecosystems, species and genes, and the ecological processes that support them.

Chevron works with communities, regulatory agencies, industry groups, academia and conservation organisations to take action to help protect and enhance biodiversity. Our aim is to develop an understanding of potential risks and use mitigation to avoid, reduce, restore or offset potential impacts on biodiversity.

We use tools and technologies to help us understand potential impacts to biodiversity and leverage the output from these tools and technologies to identify potential opportunities for improvement.

what we’re doing

A flatback sea turtle retuns to the ocean after nesting on an Australian island.

turtle monitoring

Flatbacks are the only species of sea turtle listed as “data deficient” by the International Union for Conservation of Nature, meaning we don’t know much about them. Extensive research is needed to help protect the species from threats like fishing and pollution and establish an effective conservation plan. With the support of a leading marine conservation consultancy, more than 7,500 adult female flatbacks have been tagged on Barrow Island.

eDNA

We are using Environmental DNA (eDNA) technology, which detects DNA fragments in environmental samples and matches them to known species’ DNA sequences in online libraries to identify which species are present in an area. Enabled by recent advances in DNA sequencing technology, eDNA is faster, more cost-effective and more powerful than most conventional ecological measurement methods. eDNA allows a comprehensive assessment of local environments and is highly sensitive to detection of rare, threatened or invasive species. We have applied eDNA in a variety of environments, including to understand and manage the potential risks of alien invasive species associated with marine transport operations; to test for the presence of rare, endangered or invasive species prior to the commencement of new operations; and to provide a baseline data collection approach for monitoring.

 

Mobile solar lighting towers on Barrow Island.

solar lighting

On Barrow Island, 35 solar mobile lighting towers (MSLTs) support the safe completion of critical night works and the displacement of traditional diesel-powered units. Between March 2021 and February 2024, the EcoQuip units have reduced diesel consumption by more than 700,000 litres and abated in excess of 1,800 tonnes of CO2. The solar lighting towers produce zero scope one emissions, operate with no noise and utilise amber-coloured LED Lumineers to minimise impact to animals and marine life.

 

The Green Sawfish is classified as critically endangered by the International Union for the Conservation of Nature

micro-tunneling

The Wheatstone facility is located near the Ashburton River Delta, a dynamic system of dunes, lagoons, sand spits and tidal flats. The delta provides important habitat for many vulnerable species, including the green sawfish. An engineering solution was developed to bore underneath the shoreline area to ensure no disruption to local coastal processes or disturbance to mangroves occurred.

We employ a stringent Quarantine Management System.

QMS quarantine management system

We have a comprehensive Barrow Island Quarantine Management System (QMS) in place that seeks to prevent the introduction of non-indigenous species through pre-border screening of cargo and passengers prior to arrival on Barrow Island – a Class A Nature Reserve. This is complemented by on-island inspection and surveillance activities as well as a control and eradication capability.

 

thevenard island

The Chevron-operated Thevenard Island Joint Venture oil facility operated between 1989 and 2014. Together with our local business partners, we’re undertaking important rehabilitation works on Thevenard Island to restore the local environment and protect its unique biodiversity. The rehabilitation process also included working with local partners NTC Contracting, Workpower and the Onslow Indigenous Sea Rangers to plant more than 160,000 native seeds - supporting local jobs and businesses in the process. Monitoring of rehabilitation will also be carried out over the next few years.
