Optus Sustainability Actions

Published its 27th sustainability report

Optus published a 2026 Sustainability Report covering 1 April 2025 to 31 March 2026. It says this was its 27th annual sustainability report and its first full-year report under a refreshed 2030 sustainability strategy. The report links sustainability to business resilience, public trust, and service reliability, not just environmental work. It also says Optus issued a separate statutory FY26 sustainability report aligned with AASB S2, which is Australia’s climate disclosure standard for qualifying companies.

Cut emissions and raised renewable power

Optus reported that its Scope 1 and Scope 2 market-based emissions fell 17% year on year. Scope 1 and 2 are direct emissions from owned operations and emissions from purchased electricity. The company said this drop was helped by a renewable electricity power purchase agreement, which is a long-term contract to buy power from renewable sources. It also said renewable electricity rose from 21% to 35% of total electricity demand, while solar deployment and the removal of older equipment reduced electricity use.

Improved climate resilience for networks

Optus expanded backup power and emergency connectivity during FY26. It deployed 147 portable generators, added permanent generators to 10 mobile sites, installed critical power extenders, and increased satellite-supported emergency equipment. It also took part in CSIRO’s Telecommunications Resilience Investment Pilot and tested 5G-supported emergency response tools. This matters because, for a telecoms company, climate risk can affect whether people can make calls and reach emergency services during outages or extreme weather.

Expanded supplier emissions work

Optus said Scope 3 emissions make up about 69% of its combined emissions footprint. Scope 3 means indirect emissions across the wider supply chain, such as bought goods and services. To address this, the company expanded its Supplier Engagement Program to 250 suppliers and gave carbon-accounting education to 64 small and medium-sized businesses. It also said some supplier contracts now include expectations for emissions cuts and data on Scope 1, 2, and 3 emissions.

Reported customer remediation and support

Optus said it continued remediation work for customers who may have been sold products or services they did not need, could not afford, or could not use. It also reported support for 28,212 customers through its Specialist Care team and 63,060 customers through its Financial Hardship team. The report frames customer vulnerability as a governance issue, showing that consumer protection is part of its sustainability and risk work, not a separate side project.

Strengthened governance after failures

Optus said it formalised sustainability responsibilities across the Board, Risk Committee, Executive Committee, and Sustainability Team. It also linked governance to the September 2025 Triple Zero disruption, which was caused by human errors and process failures during a network upgrade. The Board commissioned an independent review led by Dr Kerry Schott AO, accepted all 21 recommendations, and set up an implementation program. Kearney was also brought in to provide extra oversight and verification of network improvements.
