DPJ and the Environment

As I wrote earlier, the Democratic Party of Japan, which recently won a landslide election, is calling for major environmental changes, including significantly greater carbon emission targets than the outgoing LDP party. This week I learned that, on the premise of reviving the struggling Japanese countryside, the DPJ has also promised to reduce the gasoline tax and highway tolls. These pro-automobile ideas will not help with emissions targets.

Keidanren, the Japan Business Federation, is strongly opposed to the more ambitious emission goals. By calculating the difference in today’s prices between fossil fuels and renewable energy, numbers have been created to alarm the public about costs to consumers and businesses. A particularly Japanese explanation I heard from one Japanese corporate spokesperson was articulated as concern for the finances of business customers.

This organized resistance to change strikes me as short-sighted. According to a Japan Ministry of Foreign Affairs chart based on International Energy Agency data, Japan is already the world’s most energy efficient nation (calculated as energy supply per unit of GDP): three times more efficient than the global rate, twice as efficient as the US, almost twice more than the European Union, and more than seven times India and China.

In the United States, Obama has called for 25% of electric energy to come from renewable sources by 2025. The DPJ’s solar subsidies and carbon taxes will spur adoption of solar energy, benefiting Sharp and Kyocera. In a world of climate change and peak oil, investing now in renewable energy seems vital for Japan’s energy security and global technology exports.

If the focus is strictly on carbon emissions, and not renewable energy, Japan risks further dependence on nuclear energy. Already 26% of electric power in 2007, nuclear power produces dangerous waste, all the more so in a small island nation prone to earthquakes. This makes news that nuclear industry and international energy leaders are seeking to increase operating rates. From the Japan Times,

Nobuo Tanaka, executive director of the International Energy Agency, urged Japan last year to relax its “hyper cautious” atomic safety standards to increase output.

The country’s operating rate averaged 59 percent in 2008, compared with 90 percent in the U.S. and 76 percent in France, according to industry group the Japan Atomic Industrial Forum Inc.

With energy use increasing in the developing world, now is the time to debate the difference between carbon neutral and renewable energy, and the role of national governments in promoting change that can spur international competitive economic advantage.

NTT Facilities’ Green Potato

NTT Facilities Green Potato

From City Farmer‘s amazing blog, I found this photo and story about NTT Facilities‘ growing sweet potatoes on rooftops in Tokyo. This urban agriculture project makes use of wasted urban space, reduces the heat island effect, and provides local and safe food. Sweet potatoes apparently thrive in harsh sun and strong wind. The Agence France Presse story from November 5, 2008 says that NTT Facilities hopes to take their “Green Potato” project to other Tokyo office buildings and nation-wide to schools.

What prevents other corporations from implementing rooftop agriculture? Is it know-how or cost? There should be some savings by reducing air-conditioning costs (and carbon emissions), and also an opportunity to give office workers opportunities to work together and learn more about how food is grown.

An interesting video from CNN about one Kawasaki family’s choices in constructing a house with minimal environmental impact: passive daytime lighting, low flow faucets, double paned windows, solar water heater, and a roof garden for cooling the home and providing vegetables. There is also discussion of Panasonic’s Eco Idea House with an energy management network and fuel cells.

Panasonic projects a 66% reduction in carbon emission levels from 1990 to 2010 in the house of the future. And it also envisions “universal design” principles to allow for optimal usage by the elderly and disabled.
