A sustainable city, or eco-city is a city designed with consideration of environmental impact, inhabited by people dedicated to minimization of required inputs of energy, water and food, and waste output of heat, air pollution - CO2, methane, and water pollution.
A green city derives its energy from renewable sources like solar and wind, and distributes that energy through efficient and reliable microgrids.
Earth Day Network launched the Green Cities campaign in the fall of 2013 to help cities around the world become more sustainable and reduce their carbon footprint. Focused on three key elements – buildings, energy, and transportation – the campaign aims to help cities accelerate their transition to a cleaner, healthier, and more economically viable future through improvements in efficiency, investments in renewable technology, and regulation reform.
Energy
Most of the world currently relies on outdated electric generation structures that are extremely inefficient and dirty. To help cities become more sustainable, we need to redesign the current system, transition to renewable energy sources, and implement 21st century solutions.
Green Buildings
Buildings account for nearly one third of all global greenhouse gas emissions. Through simple efficiency and design improvements to buildings we can reduce those emissions drastically. To realize that vision, cities need to update ordinances, switch to performance based building codes, and improve financing options.
Transportation
Transportation is the fastest growing source of greenhouse gas emissions worldwide, three quarters of which comes directly from road vehicles. To reduce these emissions and the resulting smog, we need to improve standards, increase public transportation options, invest in alternative transportation, and improve city walkability and bikeability.
Through an informative website and a series of in-depth toolkits, the campaign will educate the public about each element of green cities and spur individuals to take civic action by signing petitions, sending letters, and organizing events.
In addition, Earth Day Network will work with partners on the ground in strategically placed cities and towns to organize grassroots efforts to improve local codes, ordinances, and policies that will help cities become model green cities.
Spanning Earth Day 2014 and 2015, the campaign will work with an international team of partners, including local organizers, non-profits, businesses, and governments to help increase public awareness, mobilize support for appropriate policies, and generate concrete commitments for innovative and replicable initiatives.
