   Global data-water symbiosis reduces AI infrastructure's carbon and water footprint.

   Environmental science and ecotechnology (Wang et al.)Published Apr 26, 2026Checked Oct 11, 2026

   “The analysis reveals a strong global spatial co-occurrence between data centres and WWTPs, enabling optimized national-scale pairings in which treated effluent is used for data centre cooling and the return heat is recovered to support sludge drying and anaerobic digestion. This symbiotic approach reduces greenhouse gas emissions by approximately 84 million tonnes of CO2 equivalent annually, conserves approximately 1300 million m3 of freshwater, and provides net annual cost savings of approximately US$95.4 billion. The greatest mitigation and water-saving potential lies in the United States, Japan, China, the Netherlands, and the United Kingdom. These findings establish data-water symbiosis as a readily scalable infrastructure solution that decouples AI from its carbon and water footprints. WWTPs are poised to evolve from disposal facilities into critical energy-coupling hubs, enabling efficient thermal and water exchange across urban systems and accelerating progress towards multiple Sustainable Development Goals.”

   Community-based research supports more just and equitable industrial decarbonization.

   Nature communications (Smith et al.)Published Sep 8, 2025Checked Oct 11, 2026

   “Industrial decarbonization refers to the removal or reduction of greenhouse gas emissions, process emissions, or embodied carbon from industry. Building from our experiences working with communities contemplating industrial decarbonization projects, we argue that community-based research can move nebulous calls for "community engagement" to processes that emphasize just and equitable governance. We first summarize the co-benefits and risks of industrial decarbonization for historically marginalized communities. We then draw from our own experiences working on community benefit plans for developer-led projects to show how community-based research can help ensure that industrial decarbonization projects benefit the communities that choose to host them.”

   Towards a better psychological satisfaction: developing a mixed multi-criteria evaluation system to urban 'Not in my back yard' facilities siting.

   BMC psychology (Cao et al.)Published Apr 15, 2024Checked Oct 11, 2026

   “Thus, the effective improvement of MCE method through an interdisciplinary view can optimise the decision process and advance the factor assessment system of siting, which helps to supplement qualitative criteria evaluation. The specific improvement steps are as follows. The first step is to introduce the mixed MCE method to improve the qualitative criteria evaluation method by pre-processing qualitative criteria with min-max standardisation and normalization. This process transfers all negative factors to positive ones and transforms the F function to linear functions. The second step is to optimise the existing two-phase siting decision-making including the feasibility evaluation phase and the MCE phase. The third step is to propose a modular criteria system composed of urban and regional spatial planning, social psychological factors and the corresponding improvement strategy of this system from three perspectives of composition, measure, and weight. We argue that the improved method could be broadly applied to optimum siting decision of urban NIMBY facilities and enhance the psychological satisfaction of residents.”

   Data center (Wikipedia)

   WikipediaPublished Oct 8, 2026Checked Oct 11, 2026

   “A data center is a physical room, building, or facility for storing, managing, and disseminating data and information, including computer systems and associated components, housing IT infrastructure, and training artificial intelligence. The United States' act of Congress, the Energy Independence and Security Act of 2007, defines a data center as "any facility that primarily contains electronic equipment used to process, store, and transmit digital information." This includes "a free-standing structure" or "a facility within a larger structure, that uses environmental control equipment to maintain the proper conditions for the operation of electronic equipment." According to IBM, data centers date back to the 1940s, with the U.S. military's Electrical Numerical Integrator and Computer (ENIAC) as an early example. Data centers have different models depending on their workloads.”
