World became a ma-jority urban in 2010
Urban growth takes off
Urban population growing by ~75 million per year
TOTAL
URBAN
RURAL
Two-thirds of the world’s population, or 6 billion people, will live in cities by 2050
THE PERIL
CONGESTION AIR POLLUTION REDUCED QUALITY OF LIFE
THE PERIL: URBAN FORM
Superblocks dominate urban development
Sprawling development and ever expanding city boundaries
RISKS LOCKING IN BAD URBAN FORM
THE PERIL: TRANSPORT
Urban infrastructure revolves around the car
Highways perceived as a mobility solution
THE HUMAN SCALE IS LOST
THE DIFFERENCE OF GOOD PLANNING
BARCELONA HAS ROUGHLY THE SAME POPULATION AS ATLANTA, BUT TAKES UP ONE-TENTH THE LAND AREA AND EMITS 5X FEWER TRANSPORT CARBON
EMISSIONS
What are the minimum requirements to building a great city?

Liuyun Xiaoqu, China
The world’s most attractive cities prioritize transportation development at the human scale
Dense networks of walking and biking paths allow for shorter, more efficient, and more pleasant commutes.

Bus-rapid transit (BRT) moves people around cities quickly and safely
Public transit must be a first-class option for transportation

Guangzhou before and after bus rapid transit
Public transit must be a first-class option for transportation
Elements of good bus rapid transit (BRT): Dedicated bus lanes occupying the center of the roadway Stations that are level to bus height and collect fare prior to boarding
An advanced country is not one where the poor move about in cars, rather it’s where even the rich use public transportation.

TODAY: District energy systems produce steam, hot water, or chilled water that is piped to individual buildings for heating and cooling
Traditional district heating systems avoid buildings’ need
for furnaces, boilers, air chillers, etc.

Microgrids offer energy security and stability, while helping increase
the adoption of renewable energy

Waste management practices aim to reduce, reuse, recycle, and recover as much waste as
possible.
