AI workloads are driving server memory capacity beyond the terabyte range, placing DRAM at the centre of both the hardware supply crisis and the environmental cost of modern computing [3]. Memory already accounts for 40โ46% of total server energy consumption , rivalling or exceeding the processor [1, 2, 8, 9], especially for training and inference of large language models [5, 10].

Astronomers have a unique perspective on the Earth, its fragility, and the absence of a โplanet Bโ. Yet the carbon footprint of their activities and instruments remains substantial. The amount of data generated by these increasingly precise technical instruments, and the subsequent computing infrastructure needed to process and store it, poses a key challenge to sustainability.

Mitigation starts by treating technical debt and digital waste as sustainability problems. Idle compute, chatty microservices, oversized payloads, unbounded concurrency, always-on resilience, and forgotten data, environments, or duplicate workflows all become permanent excess: more kilowatt-hours, more emissions, more cloud spend.
We uncover where energy is wasted in everyday systems, from...

In many science and engineering disciplines, limited representative training data, poor reproducibility and low interpretability hinder the complete integration of AI. The environmental impact of this growing technology is also of particular concern. Physics-informed machine learning (PIML) seeks to answer the aforementioned challenges, with many techniques leveraging physical knowledge to...

Time- and location-shifting of computational workloads is widely proposed to reduce data-centre emissions by exploiting variation in electricity carbon intensity. However, CO$_2$-only optimization can shift burdens to places where impacts are experienced locally, such as water withdrawals in stressed basins, worsened air-pollution exposure, and increased stress on constrained grids. We present...

One of the main challenges in adopting green software practices is the limited understanding and resources on the topic. Which components have the most emissions? How can researchers minimise their footprint and engage others? We argue that structured community-building is a critical yet underexplored mechanism for accelerating green computing adoption.
This talk highlights recent...

It is encouraging to see more and more studies published about the environmental footprint of the ICT sector. Unfortunately, the outcomes of those studies are often misinterpreted. In fact, one can look at the footprint of a product or activity in many different ways which all make sense but serve different purposes. It is very easy to mistake one purpose for another and thus derive completely...

Evaluating the energy consumption of software is inherently complex, as software itself does not consume energy directly; rather, it is the hardware on which it runs that does. Over the past few years, numerous tools and models have emerged to estimate energy consumption at various levels, such as servers, containers, processes, and transactions. When assessing the energy consumption of...

There is a growing need for standardised approaches to report the environmental impacts of computational research. Funders now require such reporting, researchers are increasingly motivated to disclose the impact of their work, and journals lack clear guidelines to support this practice. The Green Algorithms project addresses this need by providing open-source tools to estimate the carbon...

The integration of Large Language Models (LLMs) into research workflows introduces a largely opaque layer of carbon intensity. Existing approaches to estimating AI energy consumption rely on time-based heuristics or static hardware profiling, which fail to capture the non-deterministic nature of generative inference. Variations in prompt design, quantization, and decoding strategies can lead...

Just like other fields, IT has an impact on the environment. To effectively reduce the impact, it must first be assessed so that realistic and efficient actions can be proposed. That is the reason why we propose a methodology that enables organizations that want to work on sustainability in IT to do so independently in a reproductible way. Using an LCA approach that takes into account IT...
