AI must be transparent about CO2 costs - Tagesspiegel Background Article
In the Tagesspiegel background feature, our CEO Arne Tarara talks about the CO2 and energy costs of AI models and how to deal with them. how these are dealt with. Transparency is key to managing the risks properly.

Green Software Measurement WORKSHOP
We are extremely delighted to having had the opportunity to present the concept of understanding and measuring software carbon emissions to some young and information hungry students. The workshop had a 2 hour format where we first went through all the nitty-gritties of how and why software emits CO2. In the latter parts we then moved over to hands-on measuring by trying out some of our tools that work under various systems like macOS, Windows and Linux.

Green Software Engineering - Nachaltige Software-Entwicklung mit Arne Tarara
In his presentation, Arne looks at exactly what emissions are meant by this and why it is not just about energy and CO2. Arne shows which (open source) tools are available and what advantages and disadvantages they have. In this article, you will learn how emissions can be reduced and resources saved. Arne is the organizer of the EcoCompute conference and CEO and founder of Green Coding Solutions GmbH - so he has a lot of green experience.

Organizing Tech conference
The first engineering conference on sustainability in hardware & software
EcoCompute brings together software developers, hardware designer and data center professionals in order to create a sustainable digital future. We want to bring all three worlds together to reduce implementation hurdles to get sustainability for digital infrastructures into action. We aim to bring together experts, and innovators to discuss and showcase sustainable practices across these technical domains.

BEYOND BUZZWORDS: MAKING DIGITAL SUSTAINABILITY A REALITY
Many teams within our community understand the necessity of integrating their digital products into their sustainability strategies. However, in a series of recent interviews with product teams, we revealed a disconnect between awareness and action. Sounds familiar? The reasons, though straightforward, pose significant challenges: Development hurdles: Building digital products is inherently time-consuming and expensive, leading to a culture of “scoping” and prioritizing core business needs. This can unintentionally exclude sustainability features. Knowledge gap: PMs and sustainability managers often lack the technical expertise to articulate relevant solutions for their specific tech stack and codebase, with devs responding with the “you-have-no-idea-what-you’re-talking-about” eyebrow raise In this 90-minute learning session, we are aiming to bridge that gap and empower both sides to bring the topic back into your next sprint planning!

Only intelligent digitzation is climate protection
„Nur intelligente Digitalisierung ist Klimaschutz!“ This is the german headline of the article by Welt editor Norbert Lossau on digital sustainability in the WISSEN section. CEO Arne Tarara was able to share his thoughts and information on the topic of green coding with him. The message: any unnecessary use of IT should be avoided. Promoting climate protection requires intelligent digitalization!

Green Metrics Tool - Feature Live Demo
We had the opportunity to present at the Cloud Native Computing Foundation - TAG Environmental Sustainability (https://tag-env-sustainability.cncf.io/) about energy and carbon measurement of open source software. In the presentation we go over all the feature that the Green Metrics Tool provides including: - Energy measurement - Carbon measurement - Embodied carbon - Modular architecture - Statistical comparisons - Timeline view - DevOps Integrations - Optimizations - and much more The live demo with all features is linked on the project page to our Green Metrics Tool https://www.green.coding.io/projects/green-metrics-tool

Green Coding Bootcamp / Workshop
Green Coding Berlin will introduce its Green Metrics Tool, EcoCI and other methods for measuring environmental impact on the backend. First session: introducing hardware and software concepts to read energy data with further steps to convert it to CO2 metrics. Also indirect energy metrics from network and cloud services are discussed with current approaches to approximate them using linear and non-linear machine learning models. Second session: the Green Metrics Tool and ECO-CI will be used hands-on to measure container based software as well as a standard Github/Gitlab CI/CD pipeline. The hands-on session will feature setting up these tools, generating measurements, comparing metrics and understanding typical caveats when conducting energy and CO2 measurements of software.

PowerHog
Energy consumption measurement during software development
The power hog is a tool that periodically collects energy statistics of your mac and makes them available to you. There are two main aims - Identify which apps are using a lot of energy on your machine. Collecting the data from as many machines as possible to identify wasteful apps globally. We provide a website for detailed analytics of your data. The hog by default uploads your measurement data to our Green Metrics Tool backend. We put in a lot of effort to make sure that no confidential information is exposed but please refer to the settings section if you want to disable the upload or submit the data to your own backend.

Relation DBMS SCER scores
A tool that benchmarks various DBMS systems agains each other and looks at energy usage The compose.yml defines all the containers we want to use to benchmark. We use the std containers provided by the various DBMS and the hammerdb container. For benchmarking we use the hammerDB system. Currently we support: MariaDB MySql PostgreSQL The benchmarking is done via the standardised TPC-C Benchmark

Green software engineering
The Green Metrics Tool is an open source framework that allows for measuring, comparing and optimizing the energy consumption of arbitrary software. The goal is to empower both software engineers and users to make educated decisions about libraries, code-snippets and software in order to save energy and thus carbon emissions.
