AWS Economic Impact Study 17 Reducing water usage in AWS data centres Recognising the criticality of sustainable water management, AWS employs multiple initiatives to improve water use efficiency and to reduce the use of potable water for cooling data centres. AWS develops a water use strategy by evaluating climate patterns for each AWS Region, local water management and availability, and the opportunity to conserve drinking water sources. AWS has demonstrated our commitment to water stewardship by using reclaimed or recycled water instead of potable (drinking) water in multiple regions. A key component of our water use strategy focuses on working with local utilities to expand the use of reclaimed water. In some regions, AWS has installed on-site water treatment systems to remove scale-forming minerals, enabling us to use water for more cycles in our cooling units and continue to reduce our water footprint. Thought leadership and support for sustainability innovation The Amazon Sustainability Data Initiative (ASDI) seeks to accelerate sustainability research and innovation by helping our customers to minimize the cost and time required to acquire and analyze large sustainability datasets. ASDI supports innovators and researchers with the data, tools, and technical expertise they need to move sustainability to the next level. ASDI currently works with scientific organizations like NOAA, NASA, the UK Met Office, and the Government of Queensland to identify, host, and deploy key datasets on the AWS Cloud, including weather observations, weather forecasts, climate projection data, satellite imagery, hydrological data, air quality data, and ocean forecast data. These datasets are publicly available to anyone. We are excited to bring this work on sustainability innovation to our customers and partners in New Zealand, and to share our own lessons, strategies, and tools for successfully identifying, reducing, and reporting on climate emissions.
