Mio Reggio partners with National Calendar Day to create "National Green City Day"
June 2022
National Green City Day has been officially approved by National Day Calendar, which selects only 30 observances each year from more than 25,000 submissions. Mio Reggio is honored to partner in this recognition, celebrating the progress cities are making toward sustainability and environmentally responsible urban living.
The day highlights innovative efforts to address climate change through sustainable planning, eco-friendly infrastructure, and healthier communities. At Mio Reggio, we believe children are active global citizens and play an essential role in shaping a more sustainable future — because we are all citizens of a city.
