Microsoft and AI2 have partnered with the Green Software Foundation on carbon-aware app building tools

For a long time, scientists have worried about the ever-increasing carbon footprint. The World Meteorological Organization recently said that the global temperature has a 50% chance of exceeding 1.5 degrees Celsius within the next five years. Scientists believe this should be the upper limit to avoid catastrophic climate change. They believe that even if humans reach this threshold in the long term, the quality of human life and other supporting ecosystems will experience enormous upheaval. Sustainable AI is believed to have the ability to minimize carbon emissions. This can be accomplished by incorporating renewable energy into the power grid or reducing 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 high cost in terms of power. As a result, ongoing research is being conducted to ensure that AI models make better use of computing and energy resources. Since carbon emissions occur when electricity is not carbon-free, the energy is similar to an actual carbon footprint. The carbon intensity of a network can vary with location and time and is sensitive to slight changes in a carbon-intensive generation. Due to fluctuations in electricity consumption, this carbon intensity varies considerably over time and seasons. This opens up the possibility of profiting from such spreads. This is called carbon-aware computing.

Knowing what activities are possible and their influence 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 a set of people, standards, and technologies that will make this possible. Cloud users and providers cannot operate effectively without a uniform framework to measure operational carbon emissions at a granular 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 for measuring software carbon intensity (SCI) to calculate operational carbon emissions of 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 that powers the data center. The ICS uses a “consequential” carbon accounting technique, which seeks to quantify the incremental 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 performed on equal source estimates of emissions. A review of a variety of activities a user can undertake to reduce their IBS using carbon-conscious tactics was also conducted. It has been discovered that selecting an appropriate geographic region is the most crucial factor as it can minimize SCI by more than 75%. Time of day has also been shown to have a primary influence since there is considerable reduction potential to capitalize on diurnal fluctuations in carbon intensity as a function of working time. To reduce 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 operating carbon estimates are based on a single drive cycle. Calculating the overall carbon footprint of AI requires looking at the entire lifecycle of an ML model. Early phases of exploratory training, hyperparameter tuning, deployment and monitoring of the final model would all fall into this category. Major cloud computing providers, such as Microsoft, already use market-based mechanisms such as renewable energy credits (RECs) and power purchase agreements to power their cloud computing data centers with a Carbon Neutral Energy (PPA). As businesses and developers step up, centralized and interoperable tools are needed to make this possible at scale. The Green Software Foundation’s Carbon-Aware Core SDK is a new open-source project that aims to create a flexible, agnostic, and open core. As a result, native carbon-sensitive capabilities can be built into software and systems. “Measuring the Carbon Intensity of AI in Cloud Instances”, a study by the researchers, shows how cloud providers offering information on the carbon intensity of software in an actionable way would allow developers and consumers to reduce the carbon footprint of their AI workloads. This requires the development of interoperable measurement tools; only then can effective carbon management policies be developed. Since the potential of this project extends beyond machine learning workloads, the team invites developers and other academics to contribute to open source.
