Regarding recent comments by the government about Japan's agreed Kyoto Protocol targets: The fact that Japan is struggling to meet its goals is due to nothing more than bad leadership. I work with companies in Japan that lease offices, and they are keen to make their new offices more environmentally sustainable and energy efficient.

Yet, because the government has refused to make laws that force companies to do anything, they have difficulty getting the budget for it. More companies are starting to do it, but the efforts will be too little too late. If the government wants to achieve a 20 percent reduction in carbon emissions by 2020, or 50 percent by 2050, it will have to back up these goals with laws.
