Its Lexington, Kentucky site is among only three globally to be honored as a World Economic Forum Sustainability Lighthouse.

Using smart technologies like IoT, power metering, and analytics, the plant has significantly cut energy usage, CO₂ emissions, and water consumption. In Wuxi, China, Schneider’s Smart Factory promotes emissions reduction and circular practices, earning it status as a WEF Advanced Lighthouse. Barcelona’s facility in Spain runs as a zero-carbon factory, powered by an integrated energy system combining solar power, batteries, and EV charging infrastructure.

Google – Sriperumbudur, Tamil Nadu, India
Google’s hardware production facility in Tamil Nadu, run with Dixon Technologies, is a cornerstone of its shift toward a localized, decarbonized supply chain. The site supports Google’s mission to achieve 100% carbon-free operations by 2030 and follows stringent standards for sourcing and emissions.

Under Google’s Supplier Responsibility programme, the plant employs energy-saving practices and sustainable materials in its assembly processes. It not only serves the Indian smartphone market but is also poised to become a major global export base, aiding regional growth and reducing dependence on other Asian manufacturing hubs.

Lego Factory – Binh Duong, Vietnam
Lego’s newly launched US$1 billion factory in Vietnam sets a new sustainability standard in the region. It will run entirely on renewable power by 2026, drawing energy from rooftop solar panels, Vietnam’s first large-scale battery storage system, and green power procurement agreements.

Buildings within the campus have earned top sustainability certifications, and the company has planted twice as many trees as were removed during construction. This flagship facility underpins Lego’s goal of eliminating greenhouse emissions by 2050 and will help meet rising demand in Southeast Asia while meeting global environmental benchmarks.

Procter & Gamble (P&G) – Taicang, China
P&G’s facility in Taicang, Jiangsu, operates using only renewable power and features innovative water conservation technologies. The plant recycles steam condensate for reuse and captures rainwater to irrigate landscapes, minimizing freshwater consumption.

Through effective recycling and zero-waste-to-landfill operations, the site reinforces circular economy principles. Smart building systems also cut down on power use, and the factory supports P&G’s wider aim to fully transition to renewable and recycled materials across its product lines. As the first of its kind in China to seek LEED certification, this facility symbolizes P&G’s drive for global sustainable manufacturing excellence.

Unilever – India, UK
Unilever’s Dapada facility in India, operated by Hindustan Unilever Limited, has been honored by the World Economic Forum for its use of advanced digital tools to drive sustainability. By implementing AI, machine learning, and analytics, the plant has improved resource use, cut emissions, and significantly reduced product development times and costs.

In Liverpool, UK, Unilever’s Materials Innovation Factory, built in collaboration with the University of Liverpool, leads in robotic materials science research. This facility plays a key role in product innovation, including the development of more efficient, sustainable cleaning solutions like Persil Wonder Wash.

Nestlé – Serbia, UK
Nestlé is making progress on sustainability through two standout facilities: Surčin in Serbia and Fawdon in the UK. The Serbian site has completely eliminated landfill waste, showcasing exemplary waste management practices.

In the UK, the Fawdon factory is piloting initiatives to halve water usage and CO₂ output in just two years. These efforts represent Nestlé’s global commitment to reducing its environmental impact while maintaining innovation in food manufacturing.

Siemens – China, US, Germany
