On the eve of G-20 meetings this week in the heart of the United States, the momentum of climate change leadership is ironically taking shape in Asia and Europe.

That is borne out by new announcements on smart, green city programs, as well as other major developments coming from China and South Korea leading up to December's Copenhagen Climate Change Conference.

Before I get to the wired city news, some relevant signs from the tea leaves of Asian political leadership:

Both China and South Korea are home to an emerging model of cities that are being planned with combined IT infrastructure and management systems that reduce carbon and resource use in construction, waste production, water and energy use, teleworking, transportation and mobility.

South Korea, in particular, is designing its national stimulus program and economic development strategy around the convergence of sustainability planning, IT innovation and energy usage.

It's not surprising that South Korea's largest development project, Songdo International Business District, optimizes low-carbon design with ubiquitous information technology.

In China, IBM announced last week an eco-city research center, which will feature a collaboration between the global technology provider and the national government on the latest IT-based water management systems and more.

China is also designing Eco City standards through its central government's Ministry of Housing, Urban-Rural Development; it is looking to such planning and management systems that can scale up to meet 350-400 million more people that its cities will house by 2020. China is said to be looking beyond reducing carbon emissions and water use: it is taking into account other macro design factors such as as climate change adaptation, including natural disaster risk. 

The developer of Korea's Songdo, Gale International, and Cisco also announced last month an agreement with China to develop a city district in Changsha, Hunan Province.

Meanwhile, the European Union is not sitting idle when it comes to wiring its cities for sustainability. After hosting a "Green and Connected Cities" session before The European Union's Committee of Regions last year (at which I addressed delegates), Europe announced last week it is putting significant investment into wiring and enabling 30 cities for advanced IT energy efficiency capabilities.

And the United States? Beyond Boulder, Colorado, which has recently implemented the model for the nation's first Smart Grid-connected city, looks like we will be spending our days leading up to Copenhagen mired in a decades-old health care debate while the rest of world is shaping a future of innovation.

In my previous post, I highlighted how growing Asian urbanization is expected to contribute more than half of the world's growth in greenhouse gases over the next 20 years. Now I will review what's being attempted in Asian cities and elsewhere in order to positively alter that disturbing forecast.

The US and other Western nations are by no means immune from culpability in global climate change, since the US and Europe have contributed most of the existing excess greenhouse gases (GHGs) in our global climate over the last 100 years.

Because of that history, the onus is upon more developed parts of world, including North America, Europe and parts of Asia, to help plan and develop models for new cities in Asia. These models need to take into account climate change, local culture, the latest IT and communications technologies, and more.

New cities or districts must not be only be low- or zero-carbon, they must also address climate change adaptation, which in practical terms means designing for water and food security and natural disaster risk management.

What are the best global models that Asia should draw upon? Masdar, in the United Arab Emirates (Abu Dhabi), is one good model, though its small expected total population (50,000) and unique design can't scale up to Asian-sized growth requirements.     

Masdar is piloting scores of new designs and technologies that reduce energy use, particularly in passive energy reduction (cooling and solar) and PV solar. Masdar also reduces water use with information system-linked leak-detecting sensors and by recycling dew. This desert-located site even recycles ambient moisture in the indoor air, which includes evaporated human sweat. 

Besides the techno-wizardry, Masdar offers economic sustainability, through a viable financing "eco-system": it has created a tax free-foreign enterprise zone that has drawn in support from General Electric, Credit Suisse and the United Nations' Clean Development Mechanism.

South Korea's Songdo International Business District is planned to reduce energy use 30 percent in every building through the use of double building skins combined with sophisticated information technology and communications control systems. Songdo is on a scale to which China can relate, with 60,000 residents and 300,000 workers expected by completion in 2015.

Some Chinese green new city false starts (so far) have included Dongtan and Qingdao Eco-Blocks, both of which were approved or studied by the national and local governments but have so far failed to be greenlighted.

While Dongtan was to be on a scale of 20,000 inhabitants to begin and was mainly to be powered by renewable energy, it had plans of increasing to 500,000 by 2030. That still wasn't necessarily big enough for the needs of China, which may add 800 million or more people to its cities over the next 30-40 years, many of them in new cities or new city zones of 500,000 to 5 million. Because of local corruption, ground for Dongtan was never broken despite ambitious plans and international project participation from ARUP Engineering.

Qingdao Eco-Blocks, with 2,000 to 100,000 housing units and mixed-use, transit-oriented development, meanwhile, did have modular applicability to Chinese new city development. The Eco-Blocks project, though, did not get slated into Phase 1 of the city's development pipeline, according to Harrison Fraker, retired professor from UC Berkeley's Institute of the Environment. While at Berkeley, Fraker and the Institute helped devise the plan for the resource (water, waste, energy) "self-sufficient" city.

It seems the Eco-Blocks were too complex at their present stage of planning to fit into China's massive national new city construction mechanism, which is constrained by the need for speed. The Eco-Blocks are now being considered as a prototype for NASA Ames research, Fraker said.

The immediate fate of Tianjin Eco-City has greater potential in China. A Chinese and Singaporean cooperative has been holding design competitions for a large section of Tianjin, the third largest municipality in China, which has an overall population of more than 8 million.     
Besides cultivating financing, the Tianjin Eco-City is attempting to develop sophisticated software that can model the use of materials, energy, water, land, transportation and other resources, in addition to carbon and waste outputs.

Other noteworthy green community models beyond Asia include the Kalundborg (Denmark) Eco-Industrial Park; Hammarby, Sweden; and Kronsberg, Germany.

Kronsberg, a community of 6,600 near Hanover, addresses the critical element of local food with greenhouses using renewable energy, which can offer a large-supply of nutrition requiring less carbon than the transport-heavy global food model.

Combined with the myriad waste re-use and energy generation opportunities that can come with sustainable organic agriculture and food processing, the food element has been a significant missing element in most "eco-cities."

Kronsberg reduced its greenhouse gases by 45 percent compared to average new construction.This was accomplished through the use of advanced building insulation in concert with district heating systems, which use waste heat from municipal processes to warm water that is piped throughout the community for everyone's use. The suburban area cut overall per capita CO2 by an estimated 60 percent through transit oriented development including major bicycle infrastructure.

Reducing the life-cycle impacts of construction and infrastructure materials is another area not being well addressed by current eco-city planning and design--no large-scale pilot projects exist that precisely measure and manage life-cycle material impacts.

If new cities can combine integrated planning for better carbon management, regional food systems, life cycle material impacts, water scarcity and biological/ cultural diversity, they will be much better prepared to host the world's new majority that is headed their way.
