We need to find a new stability and status quo in our use of resources - stewarding the limited resources we have to support environmental sustainability - making technology circular, deciding when it's best **not** to create something new, or focussing on renewal and repair. It's about creating a new norm where we carefully consider our resource consumption, energy efficiency, and carbon emissions without compromising technological advancements. Establishing this new balance meshes with my passion for driving societal change.

Measuring water impacts requires accounting for both direct and indirect sources. Data centers [contribute to water consumption in three main ways](https://www.eesi.org/articles/view/data-centers-and-water-consumption): cooling, electricity generation, and semiconductor manufacturing. Many facilities use evaporative cooling systems that remove heat from servers through water evaporation, and beyond the facility, power generation itself is water-intensive. Earlier in the supply chain, the production process of semiconductors used for compute hardware also requires water.

Added capabilities have led to an exponential increase in model size and complexity in the past ten years. Increased size and complexity automatically bring more computing. [OpenAI](https://openai.com/blog/ai-and-compute/) reported that the required computing to train state-of-the-art deep learning models had increased 300,000-fold since 2012. For example, training the GPT-3 model consumed approximately 190,000 kWh of energy and produced 85,000 kg of CO2.

But what about after the training phase, when a model is deployed? This is where we have been facing an information gap. Previous studies had primarily focussed on energy use during the training phase of the model. The TSU study is bridging the gap by taking on the inference stage, where the model is put into action on live data to produce actionable output.

**Carbon is the climate consequence.** A kilowatt-hour from a solar-heavy grid at midday carries a fraction of the carbon of one drawn from coal at night. Where and when an agent runs matters as much as how much energy it consumes. Embodied carbon, the emissions baked into the hardware, is rising rapidly as the industry expands AI data centre capacity.

**Water is the local impact, and its use by AI is increasingly drawing community attention.** Agentic workloads, with their long execution times and sustained GPU utilization, generate heat that needs cooling. In response, many data centers rely on evaporative cooling, which can consume millions of litres of freshwater per facility per day. Water impact is also place-specific—a litre consumed in a stressed watershed is not interchangeable with a litre elsewhere. The available alternatives are more energy-intensive and increase the carbon cost instead.

You cannot optimize for one resource and assume the other two will follow. A carbon-aware schedule that shifts workloads to a renewable-heavy region in a drought zone can lower emissions while worsening water stress. An efficiency gain that reduces tokens but routes inference to newer hardware with high embodied emissions can lower energy and raise total lifecycle carbon. **Green software practice has to hold all three in view.**

AI workloads were exploding across the software industry, but nobody had a standardized way to measure their carbon footprint. Training GPT-3 alone produced approximately 500 tonnes of CO₂ emissions — equivalent to a petrol car driving roughly 2 million kilometres — and close to 1,300 megawatt hours of electricity. And that was just one model from 2020.

The problem was not that organizations were unaware. Many GSF member organizations had sustainability commitments. But multi-million pound infrastructure decisions were being made without understanding relative carbon efficiency. Existing measurement approaches each captured only a slice of the picture: some covered only inference, others only training, and none addressed the full AI lifecycle.

The fragmentation was paralysing. Multiple metrics existed — the Green AI Index, EcoLogits, EnergyScore — but none were consensus-built, none had a pathway to policy or certification, and none incentivized the full range of engineering optimizations that could actually reduce emissions. The question was whether the industry could agree on a consistent, trustworthy way to measure that footprint so they could systematically reduce it.
