"International standards provide the guidelines and benchmarks needed to measure and improve the environmental impact of AI. Codifying established best practices, standards help mitigate risks such as high energy consumption and lifecycle emissions. They also provide measurement methodologies to assess GHG emissions and energy consumption, and thereby identify the actions needed to improve. Achieving this vision of sustainable AI that offers powerful tools for climate action will demand close collaboration among a diverse array of stakeholders from government, industry, academia and civil society. The International Telecommunication Union (ITU) stimulates this collaboration as the United Nations specialized agency for information and communication technologies. This report explores the environmental implications of AI and presents a summary of relevant standards available and under development. It highlights the importance of a coordinated, international approach to standardization and the need for continued engagement and cooperation across all sectors." (Foreword)
