Treasury Wine Estates (TWE) has released its Cultivating a Brighter Future report, outlining the wine producer’s progress against its sustainability agenda.
The report details adaptation and mitigation projects across its global vineyards and production facilities, including on-site solar systems, electric vehicle charging, alternative fuel transition, water preservation, sustainability certification and process automation.
“The changing climate presents challenges for all agricultural businesses, and our ongoing investment represents our long-term commitment to sustainability in wine production,” said chief supply and sustainability officer at Treasury Wine Estates Kerrin Petty.
“We’ve been custodians of some of the world’s best viticultural assets for almost two centuries, so continuing to care for the environment for generations to come is a natural progression.
“In this decade of action, it’s critical that industry, government, and academic institutions come together to respond to challenges.”
Future projects aim to mitigate risk and adapt to the changing climate over the short term, including smart meter installation and building climate control, alongside longer-term initiatives focused on water security, vineyard management practices, redevelopment, and growing region expansion.
Sustainability highlights from the 2025 financial year include:
- A transition to 100 per cent renewable electricity across Treasury Wine Estates’ global operations, as part of its commitment to achieve net zero (scope 1 and 2) by 2030. The milestone is supported by 34 on-site solar systems generating 5,600 MWh, representing an investment of more than $31 million over the past four years.
- The opening of a $15 million in-house facility for no- and low-alcohol wine production in South Australia’s Barossa Valley, reinforcing TWE’s focus on innovation and its new production process designed to preserve a wine’s essence while reducing alcohol content.
- Sustainability certification achieved for more than 98 per cent of global winery and vineyard sites, supporting biodiversity, soil health, traceability and transparency for consumers. In Australia, more than 31 million litres of wine were sustainably certified.
- Ongoing investment in adaptation through a partnership with Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation, to develop mildew-resistant and climate-resilient grapevines using heritage vines from the Barossa Valley and Coonawarra regions through selective breeding techniques.
“We’re working hard to embed sustainability in everything we do: analysing water use in vineyards, diverting waste from landfill, installing large-scale solar systems, and investing in scientific collaborations on long-term adaptation projects,” said global director of sustainability at TWE Michael Parks.
“There are challenges ahead for the global agriculture sector, but through our bold sustainability ambition and financial investment, we’re optimistic about making a difference to the future of wine, viticulture, and our planet.”
