Chicago, as a big city of America, urban development impacts sustainability so much. Mayor Emanuel said “A sustainable Chicago is a city that spends less on energy use with each passing year, creates good-paying jobs in up-and-coming industries, responsibly maintains and upgrades its infrastructure, and ensures every Chicagoan has the opportunity to live a healthy and active lifestyle.”
To balance environment and economic development, government and organizations should focus on environmental legal advocacy and eco-business innovation—seven main themes are proposed— economic development and job creation, energy efficiency and clean energy, transportation options, water and wastewater, open space and healthy food, waste and recycling, and climate change.
In these themes, waste of water is a marked issue. To deal with the problem, the Northeastern Illinois Planning Commission is considering Water Supply Planning that presents increasing the price of water to reduce waste. The plan uses an out-side factor to affect people’s water use habit for saving water. With the developing of economy and society, environment has changed over time. That means the history or implementation of the regulation changed according to current situation. In the past, industries are not advanced, so energy use was balanced to its self-cycling. The policies were not strict. But now, energy demand exceeds the quantity of sources, thus more policies and regulations are published.
