I've recently come across the idea of Regenerative Cities in my Coursera.org Climate Literacy class. An idea to take sustainability to the next level and possibly the only way to ensure a vibrant future. This method of building considers that sustainability might not be enough and that positively contributing to the ecosystem might be necessary. Buildings contribute around 80% of the CO2 humans produce so they are appropriately the main concentration when looking for ways to reduce energy consumption. This is a brand new idea to me and I know I will have fun exploring it! First stop Futurepolicy.org.
Any knowledge on the subject is most welcome!
