 According to the World Bank, by 2030, cities are going to produce more than 80% of global GDP. More than 70% of people will live in the cities. In China right now, the city is generally more than 80% of the total carbon footprint. And also, I think, the city is really the center of lots of the economic activities, social and political. It's a sort of unprecedented era of the urbanization development that gives us both opportunities and also challenges. China, traditionally, is a rural country, but that has changed during the past 30 years. We have moved about 500 million people into the cities. That has created lots of challenges, congestion issues, pollution, transportation, living standards. China is trying to complete the urbanization process in 34 years, whereas in other countries they have gone through about 200 years. We hear all the smog issues that happen in the three main focus areas in China, the Jingjingji, Beijing Tianjin area, the Yangtze River Delta, and also the Pearl River Delta. I think garbage is definitely another issue. Water certainly is another issue. But one of the very interesting initiatives China's government has taken is on this low-carbon city initiative. So in this pilot program, the government has helped the city set up a target in terms of the total carbon footprint of the city. And then there are various ways to help the city achieve that goal from re-industrialization, through city planning, through transportation, through low-emission buildings, and also all the way to people's behavior, like what's called green consumption, green supply chain behaviors. But I think we have a golden opportunity in China right now because there's a place called Xiong'an, which is 100 kilometers south of Beijing, where China is trying to build a new capital or sort of a sub-capital of Beijing, trying to channel out some of these existing functions of Beijing so that Beijing can get less populated, less congested. And I think that's basically a plain piece of paper for us to start from scratch and do some really good planning and integrate all these different ideas together. And that's where yesterday afternoon we had a session on the forced industrialization, urbanization, in which the head of the Planning Academy of China basically said, you know, this is really the opportunity and probably the only opportunity for us to demonstrate that. And once that can be demonstrated, because that is going to be the sort of the plan, but clearly the next 10 years is really critical. But I think if we can prove that works, then we can spread that idea to other places.
