Sustainable City: CHICAGO

Sustainable City: CHICAGO 


The dense city center of downtown Chicago has an extensive mass transportation network with 144 rail stations and over 100 bus routes. Chicago Transit Authority has been able to cut its GHG emissions by incorporating more energy efficient transit options even while expanding…but, overall, the city of Chicago is also still very green- 12,429 total acres of in Chicago (including land managed by the state and county, with 8,100 acres of that parkland managed by the city)- 8.5% of the land area of Chicago is park space open to the public. 

Chicago has benefited from green urban planning, and the City of Chicago has worked hard to put in motion plans to transform the city into one of the world’s brightest examples of a sustainable metropolis. A path to this goal is found in the 7 themes of “The Sustainable Chicago Action Agenda. These 7 main themes include- Chicago’s Climate Action Plan, Energy Efficiency & Clean Energy, Waste & RecyclingWaste & Wastewater, Transportation OptionsEconomic Development & Job Creation, and Parks & Open Space.

Chicago has developed a citywide Climate Action Plan that mirrors the goals of Chicago’s Sustainable Action Agenda. The Chicago Climate Action Plan includes climate change mitigation strategies featuring: energy efficient buildings, clean & renewable energy sources, improved transportation options, and reduced waste & industrial buildings.

One of the aspects of the plan the City of Chicago has been most successful at implementing, and a major part of that which makes Chicago a sustainable city, from an energy use standpoint, is developing sustainable energy efficient buildings; another is the city’s implementation of sustainable technology with regard to retrofitting buildings. With regard to LEED and Energy Star buildings, Chicago has the highest percentage (at over 65%) of LEED certified/ Energy Star certified office buildings among the top 30 real estate markets in the United States.

LEED stands for leadership in energy and environmental design, and certifies buildings that demonstrate excellence in the following categories: sustainable sites, location and transportation, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation in design.

In order to make even more advancements in residential and business building’s energy and water efficiency, and reduce greenhouse gas emissions associated with buildings in the citythe City of Chicago has launched Retrofit Chicago
Energy efficiency is a priority for strengthening Chicago— helping Chicago to be at affordable, modern, competitive, attractive, livable, and sustainable city. Retrofit Chicago’s energy efficiency pursuits help: 
  • Create Jobs  
  • Save Chicagoans money 
  • Improve air quality for workers in commercial buildings 
  • Reduce greenhouse gas emissions 
  • Demonstrate Chicago’s environmental leadership"

City buildings in Chicago are to be powered by 100% renewable energy (100RE) by the year 2025. The city's Mayor Rahm Emanuel along with Chicago Public Schools, Chicago Housing Authority, Chicago Park District and City Colleges of Chicago, hope that when the 100RE program for Chicago is fully implemented, the commitment would make Chicago the "largest major city" in the U.S. to supply its public buildings solely with renewable energy.  

The city of Chicago has initiated a Sustainable Development Division (SDD) to address sustainability concerns in the development of buildings in Chicago. 

The Sustainability Division provides technical assistance for [developers]...required to meet the City of Chicago's sustainability standards, specifically city-assisted projects [and] new planned developments...[Chicago’s] Sustainable Development Division promotes development practices that result in buildings that are healthier to occupy, less expensive to operate and more responsible to the environment than traditional buildings. Sustainable requirements involve various levels of LEED [and] Energy Star standards for energy efficiency...The policies are intended to improvepublic roadways and parks– [and create] a higher level of stewardship of local water, air, and land resources. The division promotes strategies that absorb stormwater on site, such asbioswalespermeable pavement and rain gardens, as well as green roofs. Green roofs help to keep rainwater out of overburdened sewer systems, reduce urban temperatures, improve the air quality in densely developed neighborhoods, and reduce a building’s energy costs." - Chicago SDD
Additionally, Chicago has created the Solar Express renewable energy initiative largely to advance green building in the city. The Chicago Solar Express is a public-private initiative to bring low-cost solar panels to the rooftops of Chicago- by cutting fees, streamlining permitting and zoning processes. Since 2012, the City of Chicago and ComEd have worked with private partners and the University of Illinois, under a grant from the DOE’s Sunshot Initiative, to lower cost barriers and reduce market prices of purchasing and installing solar PV for the city.

"By committing the energy used to power our public buildings to wind and solar energy, we are sending a clear signal that we remain committed to building a 21st-century economy here in Chicago," Mayor Emanuel said. The city of Chicago will achieve that commitment in a number of ways, including on-site generation and the acquisition of renewable energy credits (mostly wind and solar energy). Jack Darin, president of the Illinois Sierra Club supports the effort, " moving boldly to re-power its public buildings with renewable energy like wind and solar, Chicago is leading by example at a time when local leadership is more important than ever.”  from:

These Chicago efforts in green building illustrate the success of Chicago Sustainability themes- substantially developing energy efficient buildings, and the retrofitting of buildings in Chicago to be LEED and Energy Star certifiedand Chicago Solar Express, as well as the widespread development of renewable energy to power buildings throughout Chicago, illustrates another sustainability theme- clean energy. 

In addition to energy efficiency and green building initiatives, the City of Chicago has developed ambitious recycling programs throughout the cityBy reducing Chicago’s waste and implementing various recycling programs, the city of Chicago is making an effort to conserve resources, reduce greenhouse gas emissions, lower its carbon footprint, and reduce space in areas surrounding Chicago currently needed as landfills. These are some of the programs offered by the city of Chicago to increase conservation in the city, especially focusing on Chicago’s recycling programs: 

  • Blue Cart Recycling  The City's Blue Cart program provides bi-weekly recycling services to single family homes and multi-unit buildings.  By recycling regularly, [residents of Chicago] can help reduce the need for landfills, lower disposal costs, reduce pollution and conserve natural resources, such as timber and water. Blue Cart Recycling includes almost every type of household waste, and had diverted over a half ton of waste from landfills in the first 10 months of 2018 alone.

In addition to robust citywide recycling program, the city of Chicago also has a well-developed mass transportation system. Chicago’s mass transit options include transportation offerings from the United States’ 2nd largest public mass transit system; the Chicago Transit Authority (CTA), which operates bus and rail lines in the city, including 144 rail stations and over 100 bus routes. 

The city of Chicago is on the way to becoming a leader in sustainable transit. Chicago Transit Authority is committed to providing integral transit options that are greener and more sustainable. CTA is a huge contributor to the city’s sustainability movement because it helps to reduce vehicle emissions by replacing automobile trips with mass transit, reduces traffic congestion and enables compact development. Mass transit options include subways, commuter and light rail trains, L’cars, and buses. 

CTA has a goal to use 100% clean energy by 2035, and has been able to cut its greenhouse gas (GHG) emissions by over 10% annually by incorporating more energy efficient transit options while expanding its city fleet, and was able to recycle over 3 million pounds of material, over 90 vehicles in one year (2015) alone. 

The city of Chicago has 1,500 railcars with electric high-efficiency rails that function as low friction rails. L’cars are a new family of railcars equipped with innovative braking systems that can transfer electricity back to the third rail, which supplements power to nearby CTA trains. The City of Chicago has launched a significant sustainable mass transportation campaign in order to reduce GHGs, decrease transit costs for the city and its residents, and to increase efficiencies associated with transit; Chicago has 1,900 energy efficient buses that were converted to ultra-low sulfur diesel engines in March 2003, since 2007 any new buses acquired have been equipped with clean diesel engines, and Chicago plans to purchase an additional all-electric buses 

Chicago has also made an effort to promote its multimodal transportation.  That includes its Bike & Ride program. This program was established to improve bicycle access to bus routes and rail stations. In order to do that, the City of Chicago helpedevelop 6,000 Divvy bikes (Divvy bikes are part of a bike-sharing system run by the City of Chicago Department of Transportation), available for rent at 580 stations across the city. CTA has also worked with car-sharing companies to make for easier access between public transit and car sharing. The CTA’s multimodal integration addresses transit-friendly development by working with the City of Chicago and other municipalities to connect their services and destinations.

Another key sustainability initiative that is helping Chicago save money and resources is the city’s waste management program. New wastewater treatments are assisting in the recovery of essential energy, solids, and water. These resources are then recycled and transformed into assets that can generate revenue for the city, and protect the environment. The city has also installed 50,000 water meters through the MeterSave program, to help residents of Chicago conserve water and reduce water bills. The city has made a $50 million investment to clean and upgrade 4,400 miles of sewer lines, while also upgrading the built infrastructure, creating a cleaner, greener infrastructure. The City of Chicago is also investing in replacing and enhancing rooftops and roadways in the city to allow for stormwater to circulate back into the environment.  

Chicago plans to continue to replace or build new green infrastructure as well as replace many sewer mains in order to control stormwater accumulation in the sewers. Sitting next to Lake Michigan and atop a swampy marshy land, water management is crucial for Chicago to becoming a more sustainable and resilient city. With a history of water pollution and toxic city water, Chicago became one of the lead innovators of waste and water management by securing federal funding in 1970 to upgrade its treatment facilities as a result of the Clean Water Act. Chicago continues to lead by example while reducing its water usage and increasing its efficiency.  

Chicago is also keenly focused on developing sustainability training and jobs among the inner-city population- namely through its flagship program, Greencorps ChicagoGreencorps Chicago provides training and jobs in environmental conservation, as well as nature-area management careers, to Chicago residents with barriers to employment. The Greencorps Chicago Youth Program, which launched in 2013, provides paid, sustainability-focused summer jobs.
