Environment

The rapid economic growth, urbanization and mortalization in 1970’s exacerbated air, water and soil pollution and land subsidence especially in Tokyo. However, we have converted the industrial fuel to low-sulfur oil, controlled diesel emission and hazardous effluent and expanded sewerage works, leading to significant improvement of the environment.
On the other hand, environmental pollution in developing countries has still been very serious as seen in the PM 2.5 issues in China and land subsidence in Indonesia. The technology and experience in developed countries including Japan need to be utilized to solve these problems. Developed countries have offered so many sets of up-to-date equipment and instrument as an aid to developing countries but they remain disused with dust on it. This indicates the needs to provide technologies acceptable to developing countries and enhance the morale and skills of the counterparts.
We have long been addressing to environmental protection and global warming mitigation from the early stages of pollution on the front line of the governmental efforts in Tokyo Metropolis and hence are qualified to propose feasible solutions to improve the environment in developing countries based on our practical experience and know how.
