Master investor Warren Buffett has said the 21st century will belong to China. Venture capitalist John Doerr has called cleantech "the biggest economic opportunity of this century."
Put those two statements together, and you have the makings of the biggest economic opportunity of the 21st century.
See, China's economic miracle has not come without costs. One of the highest has been paid by the environment. China's factories, power plants, cities, and enormous demand for natural resources have taken a severe toll on the country -- tainting the air, the water, and the land.
China is now the largest emitter of carbon dioxide in the world. Air pollution is a significant worry for athletes preparing to compete outdoors in the Beijing Olympics, and National Geographic recently reported on the "cancer villages" that line the once-pristine but now polluted Yellow River.
The good news is that the Chinese government is no longer turning a blind eye to the problem. The 11th (and most recent) five-year plan made a national "green strategy" a core platform. That means penalties for businesses that abuse the environment, as well as a focus on conservation and emissions reduction, and an emphasis on sustainable development rather than on more rapid development at any cost.
What's said is done
Starting to clean up China and having a clean China are monumentally different realities; however, the country's Xinhua News Agency recently reported on some of the significant penalties that have been levied on polluters. For example, "Companies that were identified as violating environmental laws were barred from the Canton Fair … the most important channel for Chinese exporters to expand overseas." What's more, the China Banking Regulatory Commission has "banned loans to blacklisted companies."
In other words, bad environmental practices will get you cut off from international trade and access to capital. For a small, growing business in China, that will mean fast failure.
A blueprint for green
This is not a surprise. When the Chinese government includes a platform in its five-year plan, it means business. That's why, as an investor, one of the smartest ways to think about investing in China is to focus on trends that the government has supported on the record.
This brings us to green, clean, and alternative-energy technologies, a.k.a. cleantech.
The China State Environmental Protection Agency estimated that investment in environmental protection would top $160 billion during the current five-year period (2006-2010). What's more, China's enormous trade surplus, significant construction plans, and new focus on green initiatives have the potential to turn the country into the world's largest marketplace for cleantech.
That's good for the environment, but what's even better for investors is that there are no state-owned companies operating in the space. So unlike most commercial niches in China, where behemoths such as PetroChina
One public company that's already set to work on China's environmental issues is General Electric
But even though China will be an important lever for GE, GE is an enormous conglomerate, and the green opportunities in China alone won't help the stock double or triple from here. And although not nearly as large as GE, the same holds true for big, well-known companies pursuing cleantech, such as BP
That, however, is not true for several innovative small companies.
Two small China cleantech plays
One is Fuel Tech
Wind power is also a candidate for widespread adoption in China. According to a recent report in Shanghai Daily, the government is thinking about increasing subsidies to wind power to expand capacity from 5,600 megawatts to 100,000 megawatts by 2020. GE's expertise in this niche means that it will almost certainly be involved, but small Chinese company A-Power Energy Generation Systems
Yet both of these companies -- for good reason -- have a fair amount of optimism priced into their shares. Fuel Tech trades for nearly 75 times trailing earnings, and A-Power, which was taken public via a special-purpose acquisition company, has more than tripled since last year. In other words, these are both better suited as watch list candidates than as outright buys today.
There are more where those came from
The key to taking advantage of this enormous economic opportunity is to focus on quality and to demand the right price when you buy shares. To get after both of those goals, advisor Bill Mann and our Global Gains team are in China right now meeting with a number of companies we find particularly promising, several of which operate in the green space.
