Actions

As a Green Software Advocate and Tech Sustainability Consultant, my mission is helping companies and professionals build more sustainable, low-carbon digital solutions. Since discovering technology's environmental impact in early 2023, I've become a recognized speaker at major tech conferences and co-founded Green Software Italia community. I believe in responsible technology that creates positive impact for both businesses and the environment.

In quanto Green Software Advocate e Tech Sustainability Consultant, la mia missione è aiutare le aziende e i professionisti a sviluppare soluzioni digitali più sostenibili e a limitato impatto ambientale. Dopo aver scoperto l'impatto ambientale della tecnologia all'inizio del 2023, sono diventata speaker riconosciuta in importanti conferenze tech e ho co-fondato la community Green Software Italia. Credo in una tecnologia responsabile che possa avere un impatto positivo per le aziende e per l'ambiente.

The Kubernetes Compass: Navigating Space and Time for Energy Efficiency

As the world shifts toward renewable energy, the need to align computing workloads with the availability of green resources has never been more critical. In this talk, we’ll explore how Kubernetes can serve as a "compass", guiding workloads across space and time to optimize energy efficiency. By leveraging temporal shifting to align workloads with periods of peak renewable energy generation and spatial shifting to dynamically move workloads to regions with surplus green energy, we’ll demonstrate strategies that not only reduce carbon footprints but also enhance cost-efficiency. Through real-world examples and practical insights, this session will showcase how temporal and spatial scheduling innovations can transform Kubernetes into a powerful tool for sustainable cloud operations. Join us to discover how to navigate the intersection of technology and sustainability, paving the way for a greener, smarter future.

Building a Sustainable Web: a practical exploration of Open Source tools and strategies

Being someone deeply concerned about climate change, I stumbled upon web sustainability by chance. I first learned about how to create a better User Experience taking in consideration sustainability principles and strategies. It wasn’t enough for me. I searched for more information and tried to connect some key words to “sustainable” or “sustainability” such as cloud sustainability, more sustainable cms, more sustainable programming languages, etc. At some point I didn’t know where I was and what I was searching for anymore as I couldn’t see a clear and linear path (sorry, INTJ problems). So I tried to build it myself and, as small as they seemed, I made some steps forward and open source and the community aspect had a key role. In this talk we will take a look at those steps and explore some open source tools and resources so the approach to a more sustainable development won’t seem like an insurmountable obstacle any longer.

From shy contributor to (kinda) confident community leader

At least once in the life of a software engineer or someone who works in technology, you will hear that contributing to open source is important and that you should try it. For some people, however, contributing doesn’t just mean fixing a bug or updating some documentation. For these people, it means finding the right community to proudly be a part of, fighting their shyness, and then developing the confidence to jump in.
In this talk, I will share how my experience with communities began and was basically driven by my interest on the environmental impacts of technology. My role as an advocate for environmental sustainability has been the reason why I then co-founded “Green Software Italia”, a community centred around sustainability, accessibility and a more inclusive tech world and without even realizing it I became a community leader. I will share some tips for getting started, how you can take the next step and then, eventually, become an ambassador for your community.

We need to talk about AI, Sustainable AI

Since ChatGPT's launch in 2022, GenAI has surged—but with great power comes great responsibility and environmental costs. AI could contribute 14% of global emissions by 2040, with water usage reaching 6.6 billion cubic meters by 2027. Meanwhile, only 28% of U.S. adults feel highly confident in digital literacy, a concern reflected in EU regulations like Article 4 of the AI Act. Sustainability and GenAI may seem at odds, but in this talk, we’ll explore strategies to evaluate and minimize their impact, ensuring (hopefully) a future where innovation and sustainability go hand in hand.
