Enhancing our Environmental Management System
MES received ISO14001 certification at our Tamano Works in October of 2000. This was followed by the same certification at our Chiba and Oita Works in September of 2001. Moreover, all of works shifted to the 2004 version of ISO14001 for the 2005 fiscal year. In fiscal 2010, a third renewal inspection was executed at both our Chiba and Oita Works. Both had their certifications successfully renewed. In Fiscal 2012, a fourth renewal inspection at our Tamano Works allowed it to also renew its certification. In addition, each of our works takes part in biannual system operation examinations by outside organizations.
Photographs show scenes from the renewal inspection at our Tamano Works.

Our Efforts to Conserve Energy and Reduce CO2 Emission
MES continues to promote a reduction in CO2 emission through activities such as switching from crude petroleum to natural gas in order to fuel of in-house power generation. The graph below shows MES CO2 Emission, Total Energy Consumption, and Purchased Electricity from the past 4 years.
Corresponding with a decline in production of ships and marine diesel engines, which are our major products, total energy consumption for the 2012 fiscal year has decreased by approximately 5% when compared to the previous year.
On the other hand, due to nuclear power plant shut downs, CO2 emission coefficient for each power company have increased. As a direct result, our CO2 emission went up by approximately 5% last year.

* Emission calculations have been done in accordance with the Ministry of the Environment issued "Guidelines for Calculating Corporate Greenhouse Gases Emissions."

* CO2 Emission Coefficient for Electric Power
The CO2 emission coefficient for electric power is in compliance with the "emission coefficient according to the Electric Enterprises" published by the Ministry of Environment.
In the fiscal years of 2009 to 2012, emission coefficient after adjustment was adopted from two types of emission coefficients.

Effective Use of Aquatic Resources
The graph on the right shows the MES five-year usage history of water.
MES uses both service water (clean water) and industrial water (intermediate water). As a result of water conservation efforts during the 2012 fiscal year, the amount of service and industrial water used decreased by approximately 9% in comparison with the previous year.

Our Approach for Reducing Waste
Unlawful dumping of industrial waste has become a major social problem. As a producer of industrial waste, MES is making every effort to fulfill our responsibilities in this area. One of these efforts involves our strict management of manifest. This is executed through periodical on-site inspections of disposal companies. Even more important is our effort to reduce the amount of waste itself. To realize this goal, MES works hard to recycle and thoroughly classify our wastes. Graphs below show the waste amount over the past five years, recycle rates and breakdown of waste amount for the 2012 fiscal year.
As a result of our efforts to reduce waste generation, fiscal 2012 saw a 12% reduction of wastes in comparison with 2011. Moreover, MES achieved a Recycle Rate of 84%.
We will continue our efforts to reduce waste and improve our recycle rate. In addition, we will continue to properly dispose of our waste through strict management.

Proper Management of Specific Chemical Substances (PRTR Substances)
The majority of chemical substances used by MES are solvents and pigments used in paint. Changes in output and travel amount of specific chemical substances over the past five years are shown in the graph below. The other chart describes the breakdown of chemical substances used by MES for the 2012 fiscal year.
In May of 2004, a partial revision of the Air Pollution Control Law was announced. By maintaining strict control of our emissions and by using low-emission airtight containers, MES will continue our efforts to conform to the objectives of this law.
