Environment and biodiversity

We comply with environmental laws and apply responsible standards wherever we operate. This includes avoiding new activities⁴ in natural sites on the UNESCO World Heritage List⁵ and IUCN Protected Areas⁶ , unless they are compatible with management plans in place for the area. We are also committed to achieving net zero deforestation⁷ in new activities⁸ and to preparing Biodiversity Management Plans for our major projects⁹ .

Our approach is supported by credible science, research, and monitoring, as well as relationships with communities, governments, industry, and research organisations. These collaborations aim to help us improve our understanding, strengthen our management practices, and deliver continuous improvement in environmental performance.

Woodside has a voluntary commitment, through our Environment and Biodiversity Policy, to supporting positive biodiversity outcomes in regions and areas in which Woodside undertakes activities.

Our approach to environment and biodiversity is summarised as responsible action and transparent reporting, aiming to avoid and reduce impacts to the environment and biodiversity, and managing resources efficiently in the regions where we operate.

In addition, in 2025, during decommissioning activities at the Minerva field, an unplanned event occurred when plastic clamp materials were dislodged to the marine environment. State and Commonwealth regulators were notified, and pipeline recovery activities were suspended pending revision of accepted environment plans. This was a non-hydrocarbon related release.

To uphold our commitment to managing impacts and risks, we have maintained an updated and integrated hydrocarbon spill preparedness and response framework across our global operations and activities. This approach allows us to effectively assess and manage potential spill risks to the marine environment in alignment with our environmental principles. In 2025, we conducted 68 hydrocarbon spill exercises to test our response systems and continuously improve our readiness.

Since December 2022, Woodside has committed to supporting positive biodiversity outcomes in regions and areas in which we undertake activities. Projects with positive biodiversity objectives are intended to result in a measurable outcome to a local species, habitat or ecological process.

Our focus in 2025, for our biodiversity efforts, was to support the recovery of species, habitats and ecological processes. In Western Australia's (WA)Wheatbelt this included the commencement of Woodside’s Watheroo Biodiversity Project. In the United States of America (USA) we determined the scope and location for Woodside’s US based biodiversity project which will be located in Louisiana.

In 2025, Woodside planted biodiverse seed and seedlings across approximately 3,300 hectares of land at Woodside owned properties across Western Australia. As at 31 December 2025, the total area planted under the Native Reforestation Project in Western Australia is around 16,500 hectares. Additionally, Woodside planted approximately 1,021 hectares of land in New South Wales.

None of our oil and gas production assets and new energy projects offshore or onshore overlapped with the boundaries of natural sites on the UNESCO World Heritage List¹³ .

No project or activity was undertaken within IUCN Protected Areas unless compatible with IUCN management plans in place.

No action was required for our projects and activities to conform with our Net Zero Deforestation¹⁴ commitment.

We continue to invest in strategic scientific research to support better environmental performance and outcomes. These may be used to support the baseline or monitoring requirements associated with current and future environmental approvals. Our science programs in 2025 included long-term monitoring of remote reef systems and submerged reefs off Western Australia, extending datasets to 30 years and over 10 years respectively. In addition, we conducted research in collaboration with multiple organisations to improve understanding of underwater noise and artificial light at night and their effects on marine life. Through this, we provided support for innovative technology and training programs to enhance marine fauna detection. In 2025, there were at least 12 scientific articles in international journals highlighting findings of research supported by Woodside.

We continue to contribute to joint industry collaborations, such as the National Decommissioning Research Initiative, which studies the environmental impacts, risks, and benefits of offshore decommissioning options and The IOGP Joint Industry Programmes on Sound and Marine Life and Environmental Genomics, which advance global understanding of these issues.

We strengthened our approach to water stewardship by assessing catchment water risks across our onshore assets in construction and operations—our largest freshwater users. While none of Woodside’s onshore operating assets are located in areas classified as water-stressed under the WRI Aqueduct Water Risk Atlas, we recognise that climate change, increasing demand of a shared resource and evolving regulatory expectations are creating greater uncertainty around freshwater availability and quality. Our assessments identified no immediate high freshwater risks across our onshore portfolio, however, we continue to actively monitor emerging risks to support long-term water resilience and responsible resource use.

Significant Environmental Approvals 2025

• In September 2025, the Australian Government granted final environmental approval for the North West Shelf Project Extension. Together with the Western Australian Government approval received in December 2024, this provides long-term certainty for the continued operation of the North West Shelf Project and the Karratha Gas Plant beyond 2030. Find out further information on the project.¹⁵
• In October 2025, the Trion project successfully obtained environmental approvals enabling the project to proceed to field execution as Mexico’s first deepwater development. This marks a significant milestone, as it fulfils one of the regulatory requirements set by ASEA (Mexican Regulator for Safety, Energy and the Environment) and is valid for 26 years. Find out further information on the project.
• Throughout 2025, Louisiana LNG submitted numerous required filings and several key permit renewals to relevant government agencies to support continued progress and ongoing compliance with applicable regulations.
