Guiding Green and Smart Urban Development in China
In the lead up to last month’s historic Paris climate summit, China announced that it would “embark on a new pattern of urbanization.” With cities consuming three-quarters of the China’s energy, the fate of this initiative carries global significance.
What will China’s “new pattern of urbanization” look like? China Development Bank Capital, in partnership with Energy Innovation and Energy Foundation, recently introduced a set of guidelines to help define China’s new model for urbanization. The Green & Smart Urban Development Guidelines capture the most important lessons learned from global experience on how to build a sustainable city. These guidelines are in line with China’s new central government goals and designed with practicality as a priority to suit China’s rapid urbanization.
Every city can be green and smart. The 12 Green Guidelines focus on the importance of basic land-use and infrastructural upgrades such as public transit, renewable energy, and water efficiency. The Six Smart Guidelines look at how smart technologies can optimize these urban systems. While few cities have truly explored the full integration of both green and smart, our research shows that it will be a necessary integration for leading cities in the 21st century. The Green & Smart Guidelines also come with two with comprehensive case studies - Hammarby in Stockholm and the Pearl District in Portland.
The 12 Green Guidelines are based on the principle that a few key actions taken by urban planners are critical in creating environmentally, economically, and socially thriving cities. The graphic above explains our approach in incorporating good policy design principles into each of the 12 Green Guidelines in order to ensure they are beneficial, measureable and practical. Designed as a tool for cities, the guidelines also provide quantitative benchmarks to help urban planners and others in city government fulfill the criteria.
For the Six Smart Guidelines, we look at the potential role for smart technologies in further advancing these social, economic, and environmental benefits. Many of these smart technologies have proven business models and payback periods, such as smart parking or building management systems. Applied innovatively, these technologies can increase efficiency and provide a range of benefits. For example, sensors in Barcelona’s irrigation system are helping the city more effectively care for its greenery while making money back through water savings. Smart technologies can also improve public services: cities like Stockholm are using advanced internet platforms to allow residents to register for school, scan radon gas levels, and even book weddings.
What do these principles look like in action? Take the example of the Liuyun Xiaoqu district in Guangzhou. In the place of roads, the neighborhood developed extensive walking and cycling paths. Even as vehicle ownership has risen in the city, the neighborhood has instituted car control policies, creating car-free sections of the development to protect the pedestrian culture. Here the importance of interactions between different guidelines is visible: the lack of cars does not hinder Liuyun Xiaoqu’s residents because of the introduction of mixed-use zoning. The ground floor of buildings that were formerly just apartment blocks has been converted into a wide range of shops which are always bustling with customers. Because such a wide range of goods and services is available within walking distance, residents can live a high-quality life without depending on cars.
The social, economic, and environmental benefits of the Green & Smart Guidelines are multiplied when all of the principles are applied together. A tour of one of the most sustainable developments in the world, the Pearl District in Portland, provides Chinese cities with an example of what such comprehensive sustainable development can look like. Before developing, both districts set environmental goals covering all critical elements of sustainable urban form, transportation, and energy & resources as outlined in the 12 Green Guidelines. By baking sustainability into their urban planning, the Pearl District made it part of its identity and ensured that all development would comply with the initial goals.
On top of the critical foundation of sustainable urban form and transportation, promoting non-motorized transit and public transit like Liuyun Xiaoqu, the Pearl incentivized new development to embrace the latest green technology. This vision materialized across the district and is best exemplified in one micro-neighborhood, the Brewery Blocks. This set of seven blocks is composed of all LEED certified buildings. The certification was achieved through the innovative incorporation of technology into the development: solar PV arrays line the façade of some buildings, while another hosts a district cooling facility providing cooling for the all the blocks, and all boast low-flow water fixtures for maximal water efficiency.
The Pearl’s sustainable redevelopment in line with the Green & Smart Guidelines has brought a host of benefits. The density of the district has quadrupled while easy access to parks and public transit allows for a high quality of life in the area. In a 2008 survey of Pearl residents, three quarters of residents said they drove less since moving to the Pearl; 58 percent said they usually walk, bike, or take transit to work. The district’s economy is also flourishing, driven by an influx of young, creative professionals. Between 1994 and 2010, job growth increased by 54 percent, average salary increased by 41 percent, and land market value increased by 690 percent, inflation adjusted.
There has been immense interest in China to set in motion sustainable urbanization patterns. We hope that the Green & Smart Guidelines and accompanying case studies can offer clarity on the path forward for local governments and urban developers. This is the moment for China to capitalize on a critical opportunity to make its cities ‘great’ through green and smart urban growth.

Spotlighting innovations in urban sustainability and connected technology
Collaboration extends beyond City Hall. Unlike a city like New York, where most government functions are under the purview of the municipal government, a city the size of Chula Vista (population 268,000) or smaller has to collaborate with regional partners, such as school districts, hospital districts, water districts, the port district, and neighboring cities. By keeping dialogue open and working together on major projects we’ve opened up new opportunities for economic development, smart cities pilot initiatives and education.
AVs can move more people in fewer vehicles on less congested streets compared to private cars. This means that some London streets could be made narrower and spare street space can be reallocated for other uses including bus lanes, cycling lanes, or expanded pavements. Street space can also be released for vegetation, allowing for cleaner streets and better storm water management.
The 40-million people of California are not only growing the world’s fifth largest economy, they are accelerating the transition to use 100 percent renewables in less than 30 years. Recent success, shows that reaching 60 percent renewables for energy will be achieved and an enormous win for slowing global warming, improving health, efficient economy. Beyond 60 percent, there are several paths to carbon neutrality.
