The tool uses open source technologies such as Kepler, Electricity Maps, and Boavizta to monitor energy consumption, provide real-time carbon intensity data, and track embodied emissions. The session also highlights the Green Reviews project by CNCF, which tracks emissions of CNCF projects. **Introduction to Kubernetes Emissions Insights Tool** The Kubernetes Emissions Insights Tool aims to provide a clear view of the environmental cost of infrastructure by estimating the carbon footprint of Kubernetes workloads. The tool is built using open source technologies like Kepler for energy monitoring, Electricity Maps for carbon data, and Boavizta for embodied emissions. **Green Reviews Project** The session also discusses the Green Reviews project under the CNCF's Environmental Sustainability TAG. This initiative estimates and tracks emissions of CNCF projects, showcasing how open source tools can help developers make more sustainable choices. **Practical Applications and Tools** Participants are encouraged to use best practices such as autoscaling and right-sizing applications, and to consider running workloads when renewable energy is available. The session emphasizes the role of open source tools in optimizing energy use and reducing emissions. **Call to Action** The speakers urge attendees to become ambassadors for sustainability in their communities, contributing to open source projects and applying sustainable software practices in their work. ## Importance for an eco-social transformation This session is crucial for eco-social transformation as it addresses the significant environmental impact of cloud computing and provides practical solutions to mitigate it. The Kubernetes Emissions Insights Tool and the Green Reviews project empower developers to make informed decisions that reduce carbon footprints. Eco-social designers can apply these insights by integrating sustainable practices into their workflows, such as optimizing resource usage and considering energy sources. Challenges include the need for widespread adoption of these tools and overcoming technical and policy barriers to sustainability in tech infrastructure. ## Slides: | | | | --- | --- | | ![[FOSDEM 2025/assets/Kubernetes-Emissions-Insights-Turning-CloudNative-/preview_001.jpg\|300]] | The session titled 'Kubernetes Emissions Insights: Turning Cloud-Native Green' is led by Jasper Geurtsen and Flavia Paganelli.
