Environmental Initiatives

Basic Policy
Our environmental philosophy states that the “The Tokyo Gas Group will promote the harmonious use of energy
to contribute to the protection of regional and global environments as well as to the sustainable development ofsociety.” This philosophy is reflected in our four environmental policies, and we are striving to serve as a leader inenvironmental management as we play an active role in helping to solve global environmental problems.
1 Reduce the environmental impact of customers’ energy use
2 Reduce the total environmental impact of Tokyo Gas’ business activities
3 Strengthen environmental partnerships with local and international communities
4 Advance R&D in environment-related technologies

Initiatives in Fiscal 2008
In order to carry out the Environmental Policies, we have created Environmental Protection Guidelines in three major
categories. First, global warming prevention guidelines are intended to reduce CO2 emissions resulting from the increased
use of natural gas. Second, resource recycling promotion guidelines focus on reducing the environmental impact of theCompanyʼs activities through the implementation of the “3Rs” (reduce, reuse, recycle). Third, green purchasing guidelines
promote consideration for the environment when purchasing the materials, construction work, or services necessary forbusiness activities. With these guidelines, we established concrete environmental targets and have been striving to meetthem. For example, in fiscal 2008 we reduced the level of CO2 emissions generated by customers by 721 tons. From fiscal
2009, we have enhanced our environmental guidelines with the addition of three new guiding principles, namely biodiversity maintenance, environmental communication, and environment-related technology development.
As part of our CSR efforts, in September 2007 we established the Tokyo Gas Environmental Support Fund in commemoration of having reached the 10 million customer mark. With the goal of contributing to solving global and regional environmental
problems and helping to realize a sustainable society, the Fund provides support for groups active in environmental preservation. In fiscal 2008, the Fund contributed a total of ¥10 million to 13 groups.

CSR Report 2008.

Safety Initiatives

Basic Policy
Tokyo Gas has established the following three key policies for the safe use of gas equipment.
1 Increase the use of equipment that does not cause numerous incidents of accidents,
gas leaks, or malfunctions, and of functional equipment to minimize such incidents(“hard” countermeasures)
2 Educate customers on the correct use of equipment and carry out regular inspections(“soft” countermeasures)
3 Establish emergency response protocols to be executed should a gas leak occur(emergency response countermeasures)

Initiatives in Fiscal 2008
Among our “hard” countermeasures, in fiscal 2008 we continued the “Switchover Promotion Campaign” that we began
in January 2007, targeting water heaters and bathtub water heaters not equipped with incomplete combustion avoidance devices. As part of the campaign, we agree to bear part of the cost of switching to safe appliances. Since thecampaign began, we have spent ¥2.4 billion, and the number of targeted appliances has decreased from 298,000 units
to 172,000 units.
Moreover, we continue to loan ventilation alarms without charge to ensure the safety of customers using gas equipment
in commercial kitchens, an initiative we began in November 2006. A number of accidents occurred in commercial kitchens in
2008, and accordingly we have increased our visits to customers. By the end of March 2009, out of our target of 150,000
alarms, we had installed 83,600 alarms.
Among our “soft” countermeasures, as required by the Gas Utility Industry Law, we implement periodic gas facility safety
checks for each of our customers once every 40 months. These gas facility safety inspections include checking gas pipes forleaks and testing exhaust equipment. In addition to enhancing these inspections, we are also working to promote awarenessof safe gas usage through communication with customers.
For emergency response countermeasures, we have full-time personnel with specialized skills in such areas as gas leaks.
These personnel are deployed to our Gas Light 24 emergency response bases, from which we are able to rapidly respond toemergencies 24 hours a day, 365 days a year.
To ensure the safe supply of gas, we have been systematically replacing aging pipes, such as gray cast-iron pipes andgalvanized gas pipes, with safer polyethylene pipes. We spent ¥15.1 billion on these replacements in fiscal 2008. We havealready announced our intention to complete the replacement of gray cast-iron pipes and galvanized gas pipes by fiscal 2015,
and are striving to advance this deadline as much as possible.
