As companies feel the heat from regulations and power costs, Environmental Sustainability is an increasingly important area of focus. We will summarize some of the projects who have given demonstrations during our meetings. We will reveal the latest efforts and initiatives with the CNCF Environmental Sustainability TAG, including our current working groups and collaborations with other organizations. Furthermore, we will talk about how the TAG reviews successively CNCF projects to report and improve their sustainability footprint. In the end, we will highlight some of the outstanding people who make all of this work possible.
