Our climate change objective is to deliver on the dual ambitions of limiting greenhouse gas emissions and supplying affordable, reliable and cleaner fuels to domestic and global markets.

We pursue our objective and targets with reference to the UN Sustainable Development Goals, in particular Goal 7: Affordable and clean energy and Goal 13: Climate action.

Santos seeks to be a global leader in the transition to cleaner energy and clean fuels, by helping the world decarbonise to achieve Net Zero in an affordable and sustainable way. At the same time, we recognise the importance of price stability and supply security to ensure a just transition, especially for the world’s most vulnerable communities.

Reporting our progress on addressing the climate challenge

Since 2018, Santos has published annual climate change reports that align with the recommendations of the G20’s Task Force on Climate-related Financial Disclosures (TCFD). The latest 2022 Climate Change Report outlines Santos’ climate transition strategy and action plan as we work to become a net-zero emissions energy and fuels business by 2040, in step with the goal of the UN Paris Agreement on climate change.

Our journey to net-zero emissions by 2040

Our 2021 activities

Our strategy focuses on natural gas as a reliable transition fuel source and the development of technologies including CCS, and clean fuels, such as hydrogen, as foundations for our decarbonisation pathway. To deliver on our objective, targets and Policy positions, Santos has a Climate Transition Action Plan. The Plan focuses efforts in the following areas:

  • Operational efficiencies: Initiatives including energy efficiency, reduced fuel use and flaring, electrification and renewables integration designed to reduce the Scope 1 and 2 emissions of our operations
  • CCS: Step-change technology that will reduce emissions and pave the way for new revenue streams from future clean fuels and carbon solutions
  • Carbon solutions: Opportunities to reduce emissions and generate offsets for Santos and customers
  • Clean fuels: Leveraging CCS as a platform for clean fuels such as hydrogen on a demand-led basis
  • Supply chain collaboration: Working with customers to cultivate demand for lower-carbon fuels.

The Climate Transition Action Plan is underpinned by the disciplined allocation of capital to fund delivery of our climate transition initiatives and a commitment to a sustainable and just transition for our people and the communities where we operate.

Santos achieved accelerated delivery of two of its 2025 climate-related targets in 2021 and is on track to achieve the third.

Following our strong performance toward the achievement of these 2025 targets and 2021 merger with Oil Search, we updated and strengthened our 2030 emissions reduction, emissions intensity and clean fuels targets.

Scope 1 and 2 emissions reduction:

Santos’ priority is to avoid and minimise emissions from our operations by improving our operational efficiency. To deliver on our targets we are focused on a range of initiatives across three elements of our Climate Transition Action Plan: operational efficiencies, CCS and carbon solutions. These are outlined in detail in our 2022 Climate Change Report.

Operational efficiencies and strategic investments have enabled Santos to reduce the emissions intensity of our portfolio by 20 per cent from 2016-17 levels.[1] While the merger with Oil Search in 2021 increases Santos’ absolute emissions, it has decreased our emissions intensity and we continue to focus on our decarbonisation targets.[2]

Carbon capture and storage: Step-change technology

CCS is a critical technology to meet the goals of the Paris Agreement.[3] Santos has a CCS hub strategy across our core asset areas with the potential to create more than 30 million tonnes per annum of CO2 storage capacity, with line of sight to 10 million tonnes per annum of storage capacity by 2030. Santos’ assessment and investment in step-change technology has been, and continues to be, focused on CCS.

In 2021, Santos achieved our 2025 step-change emissions target by making final investment decision on the Moomba CCS project. Santos has invested over $24 million (equity share) in developing the Moomba CCS project. Moomba CCS will be one of the world’s largest and lowest-cost CCS projects, storing up to 1.7 million tonnes of CO2 per annum at a lifecycle cost of less than $24 per tonne. Costs are expected to decrease with scale and previous studies have concluded that the Cooper/Eromanga Basins have the potential to store more than 20 million tonnes of CO2 per annum.

The merger with Oil Search is consistent with the company’s efforts to reduce emissions intensity across our portfolio. While the merger occurred after this time, the Scope 1 and 2 emissions intensity of the combined entity in the 2020-21 period would have been 47 ktCO2e/mmboe.

Climate Transition Action Plan

The decarbonisation initiatives set out in our Climate Transition Action Plan provide a pathway for Santos to achieve our climate change targets and grow our business through Carbon Capture and Storage and clean fuels projects.

Santos’ carbon mitigation hierarchy is avoidance first, followed by reduction and offsetting.

The Climate Transition Action Plan sets out how we envisage materially reducing emissions within our operational control and delivering value for shareholders through the energy transition by offering carbon solutions and partnering across our supply chain to produce cleaner energy and clean fuels that will reduce our customers’ emissions.

Future focus

Our focus is on continued implementation of our Climate Transition Action Plan as detailed in our 2022 Climate Change Report. This includes:

Operational efficiencies

Further delivery of energy efficiency projects such as increased integration of renewables and batteries into our power mix, deploying new process technologies such as LoHeat™ and capturing and recovering gas that is currently flared or vented.

CCS

Advancing our CCS hub strategy across our core asset areas. In particular, working with both the Australian and Timor Leste governments to progress the development of the Bayu-Undan CCS project that entered front end engineering design in March 2022.

Carbon solutions

Continuing to expand our portfolio of high-quality nature based-solutions and the development of new technologies, including CarbonAssist™ direct air capture technology with CSIRO.

Clean fuels hubs

Furthering studies that involve using CCS technology to accelerate the development of affordable clean fuels that support the acceleration of a future hydrogen economy.

Supply chain collaboration

Continuing to work with our suppliers to support and drive their operational efficiencies and emission reduction activities and with our customers to build demand for cleaner energy.

Just transition

Where relevant, continuing to implement sustainable development plans, underpinning work with communities to transition successfully to post-project environments.
