Amazon Web Services (AWS) is collaborating with Irish firm Trane Technologies to accelerate energy efficiency and building decarbonisation across Amazon grocery fulfilment centres in North America.

Climate innovator Trane and Amazon have announced ground-breaking results through AI to improve energy efficiency and decarbonisation in key real estate assets. The project, powered by Trane through BrainBox AI, with AWS, showcases a collaboration in building decarbonisation, reducing energy use and carbon emissions.

Initial deployment at three pilot Amazon grocery fulfilment facilities in North America exceeded expectations, achieving energy-use reductions of nearly 15%, more than double the original project targets. BrainBox AI, acquired by Trane, autonomously optimises HVAC systems, reducing energy consumption, carbon emissions and operational costs without compromising comfort or performance. Following the success of these initiatives, deployment is planned for the remaining Amazon grocery fulfilment and distribution centres across more than 30 sites in the USA. Furthermore, plans to pilot in grocery stores will begin in 2026.

“At Trane Technologies, sustainability is at the core of everything we do,” said Riaz Raihan, chief digital officer of Trane Technologies. “This strategic collaboration demonstrates how sustainability can drive strong returns while benefiting the planet. Together, we’re not only transforming these fulfilment centres but also driving meaningful progress towards Amazon’s business objectives and bold sustainability goals.”

This initiative aligns with Amazon’s two-pronged approach to sustainability: decarbonising existing buildings through smart technology while prioritising energy-efficient and low-carbon materials in new construction. It also advances Amazon’s commitment to reach net-zero carbon by 2040, while enhancing operational efficiency and long-term cost savings.

“At Amazon, we’re continually looking for data-driven, scalable ways to reduce our carbon footprint while maintaining operational excellence,” said Christina Minardi, vice president at Amazon (aws.amazon.com). “By working with Trane Technologies and the BrainBox AI team, we’re turning our buildings into intelligent systems that learn and adapt, helping us meet both our sustainability and performance goals in real time.”

In 2024, BrainBox AI was selected as one of eleven start-ups to participate in the Amazon Sustainability Accelerator Climate Tech Pilot. As part of this programme, BrainBox AI was given the opportunity to trial its technology within Amazon’s operations, contributing to broader efforts to address major sustainability challenges. Using AWS’s AI technology which contains ten AWS offerings such as S3 and Bedrock, BrainBox AI cleared the pathway for the Amazon Grocery fulfilment sites’ contribution as a driver of progress towards this goal. Its inclusion in the accelerator cemented the company as a recognised leader in climate-focused technology innovation, working alongside other start-ups to drive impactful change within large-scale operations.

“Amazon’s global scale and leadership in sustainability make this collaboration a transformative milestone,” said Jean-Simon Venne, president of BrainBox AI. “Together, we’re showing how cutting-edge AI can drive both economic and environmental impact, creating a world where every building is a proactive participant in the fight against climate change.”

Trane Technologies (tranetechnologies.com) acquired BrainBox AI (brainboxai.com) in January 2025. The companies previously teamed up for more than two years, combining BrainBox AI’s artificial intelligence technology with Trane’s building management and digital capabilities.
