Delivering sustainability outcomes Delivering sustainability and innovation outcomes Woodside’s net equity Scope 1 and 2 emissions reduction targets are to reduce 15% by 2025 and 30% by 2030 below the starting base. Targets and aspiration are for net equity Scope 1 and 2 greenhouse gas emissions relative to a starting base of 6.32 Mt CO2-e which is representative of the gross annual average equity Scope 1 and 2 greenhouse gas emissions over 2016-2020 and which may be adjusted (up or down) for potential equity changes in producing or sanctioned assets with a final investment decision prior to 2021. Net equity emissions include the utilisation of carbon credits as offsets. Please refer to Woodside’s 2024 Climate Update for further information. Woodside’s Scope 3 investment target is to invest US$5 billion in new energy products and lower-carbon services by 2030. Woodside’s Scope 3 emissions abatement target is to take FID on new energy products and lower-carbon services by 2030, with a total abatement of capacity of 5 Mtpa CO2-e. The acquisition of the Beaumont New Ammonia Project has delivered material progress towards our Scope 3 investment and abatement targets.

Cultural Heritage Management at Woodside Established track record with 40 years of operations, partnering with Indigenous communities in culturally significant areas Meaningful and respectful engagements through authorised representatives, to avoid or minimise potential impacts Each Scarborough Energy Project approval included consultations with 18 Indigenous groups since 2021 Collaboration with Traditional Custodians to conduct independent inspections of rock art and other cultural sites in Murujuga Support for cultural heritage initiatives and research

Introduction to Murujuga Located in the Pilbara region of Western Australia, over 1,200 km north of Perth, Murujuga is the traditional land of the Yaburara People Murujuga holds one of the world’s largest concentrations of rock art with more than a million recorded petroglyphs Murujuga National Park established in 2013 co-managed by Murujuga Aboriginal Corporation and Western Australian Government

World Heritage Listing of Murujuga In July 2025, UNESCO voted to inscribe the Murujuga Cultural Landscape on the World Heritage List Three outstanding universal values were recognised: Artistic achievement Living cultural traditions Human interaction with the environment The first Indigenous-led nomination accepted and inscribed on UNESCO’s World Heritage List UNESCO Murujuga World Heritage Listing1 For illustrative purposes only, circle not to scale.

Woodside on Murujuga 40 years operating on Murujuga at North West Shelf and Pluto, with considerable heritage management maturation over time Established coexistence between operations and the Murujuga Cultural Landscape Enduring partnership with the Murujuga Aboriginal Corporation >90% of the cultural heritage sites at Pluto remain intact and are actively managed to ensure ongoing protection Pluto LNG facility, Murujuga

Beaumont New Ammonia, 26 September 2025 Greater certainty for ongoing operations World Heritage properties in Australia are protected under the Environment Protection and Biodiversity Conservation Act 1999 The World Heritage Listing provides greater certainty about the cultural heritage values at Murujuga, and formalises requirements for: Continued emissions monitoring beyond the current Murujuga Rock Art Monitoring Program Development or updating of environmental and cultural heritage management plans New reporting by the Australian Government to the World Heritage Committee

Key takeaways 1 Cultural heritage management: close consultation with Traditional Owners and Custodians is fundamental to conducting our business sustainably 2 Strong relationships: through meaningful and respectful collaboration we have established a strong record of cultural heritage management on Murujuga 3 Greater certainty: the World Heritage Listing reinforces our approach to working closely with Traditional Owners and Custodians and provides greater certainty to our understanding and management of cultural heritage values
