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.
