The rate of roadway deaths in Sweden is at an international low due to an approach called Vision Zero. Now the country’s approach faces perhaps its stiffest test: the streets of New York City.

Larger green spaces may be critical to a city, as they can support more complete ecosystems. In contrast to smaller "parklets," large parks paired with high-density neighborhoods allow for healthier cities.

Cars heavily influence building planning in the U.S. due to a historical preference for suburbs, but a town in Illinois improved its economy by thinking like a city. They created transit-oriented development which prioritizes pedestrians and attracts millennials.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.

For the past three years, water levels in the San Antonio Edwards Aquifer have decreased to uncomfortable levels and drought periods may continue as the population booms. The San Antonio Water System organization has set up rules to limit water use and has recycled water for conservation frugal innovation.

New York City suffered from fires that erupted in overcrowded, run-down apartments. Then the city sleuthed through residential records and found that landlords who foreclosed let their properties fall apart and ignored safety-code violations. Greater Toronto wants to expand upon New York City’s method by using transportation surveys, census data and computer data to build transit lines.

Tulsa Public Schools drew on expertise across many sectors and extensive neighborhood input to address the issue of thousands of empty seats in local schools.
