Microsoft and AI2 have teamed up with the Green Software Foundation on tools for building carbon-aware applications

For a long time, scientists have been concerned about the ever-increasing carbon footprint. The World Meteorological Organization recently stated that the global temperature has a 50% chance of reaching 1.5°C in the next five years. Scientists believe this should be the maximum to avoid catastrophic climate change. They believe that even if humans reach this long-term threshold, human quality of life and other supporting ecosystems will suffer massive disruptions. Sustainable AI is believed to have the potential to reduce carbon emissions. This can be achieved by integrating renewable energy into the power grid or lowering the cost of carbon capture. Many people today have unparalleled access to computing power, thanks to the rise of machine learning. However, the computing demands of these workloads can come at a huge cost in terms of energy. As a result, ongoing research is being conducted to ensure that AI models make better use of computer and energy resources. Because carbon emissions occur when electricity is not carbon-neutral, energy is similar to a real-world carbon footprint. The carbon density of the network can vary with space and time and is sensitive to small changes in carbon-intensive generation. Because of fluctuations in electricity consumption, carbon intensity varies greatly over time and season. This opens up the possibility to take advantage of these distinctions. This is referred to as carbon-aware computing.

Knowing the possible activities and their impact can help users make informed decisions about reducing the carbon footprint of their workload. The Green Software Foundation is a cross-industry group working to define the set of people, standards, and technologies that will make this possible. Cloud users and service providers cannot take effective action without a standardized framework for measuring operational carbon emissions at the grain level. To address this issue, Microsoft and AI2 researchers worked with Hebrew University, Carnegie Mellon University, and Hugging Face to use the Green Software Foundation’s definition of software carbon intensity (SCI) to calculate operational carbon emissions for Azure AI workloads. Using data from WattTime, this was accomplished by multiplying the power consumption of a cloud workload by the carbon intensity of the network supplying the data center. SCI uses “dependency” carbon accounting technology, which seeks to quantify the marginal change in emissions resulting from decisions, interventions, or activities. To understand the relative SCI of a wide range of ML models, 11 separate experiments were conducted on isoelectric source estimates. A review has been made of a variety of activities a user can perform to reduce SCI using carbon-conscious tactics. It was discovered that choosing a suitable geographic area is the most important factor, as it can reduce SCI by more than 75%. It has also been shown that the time of day has a vital influence because there is significant potential for reduction to take advantage of daily fluctuations in carbon intensity depending on the duration of work. To reduce the carbon impact, workloads can be dynamically suspended when carbon intensity is high and resumed when emissions are low.

It should be noted that these savings and operational carbon estimates are based on a single training course. To calculate the overall carbon footprint of an AI, one must examine the full life cycle of an ML model. All early exploratory training, hyperparameter tuning, deployment, and monitoring of the final model will fall into this category. Cloud providers, such as Microsoft, are already using market-based mechanisms such as renewable energy credits (RECs) and power purchase agreements to power their cloud computing data centers with carbon-neutral power (PPAs). As companies and developers move in, centralized and interoperable tools are required to make this possible at scale. The Carbon-Aware Core SDK from the Green Software Foundation is a new open source project that aims to create a flexible, neutral, and open core. As a result, indigenous carbon awareness capabilities can be integrated into programs and systems. A study conducted by researchers “Measuring the Carbon Density of AI in Cloud Instances” shows how cloud service providers providing carbon intensity information to software in an actionable manner can enable developers and consumers to reduce the carbon footprint of their AI workloads. This necessitates the development of interoperable measurement tools; Only then can effective carbon management policies be developed. As the potential of this project extends beyond machine learning workloads, the team welcomes developers and other academics to contribute to the open source.
