FY2016 results Evaluation
<Customers' sites>
Reduction of CO2 emissions at customers' sites: 3.7 million tons*


We aim to reduce CO2 emissions at customers' sites by 8 million tons by FY2020. This will be achieved through efforts implemented by the Group since FY2011 to promote the use of natural gas and to develop and disseminate gas appliances and systems that have higher efficiency and lower environmental load.

CO2 emissions reduced to 3.94 million tons at customers' sites 
Third-party assured
CO2 emissions resulting from customers' use of gas were reduced by 3.94 million tons thanks to the promotion of natural gas use and the development and dissemination of gas appliances and systems that have higher efficiency and lower environmental load, including Eco-JOES and gas cogeneration systems. Increased use of gas to generate electricity due to the spread of natural gas power generation made an especially significant contribution to reduced CO2 emissions, allowing us to achieve our target.
 
○
<Electric power business>

FY2016 results Evaluation
<Industrial waste 1>
Maintaining of zero emissions at production plants (final disposal rate of less than 0.1%)
*  
Production plants operated by Tokyo Gas and its subsidiaries will maintain zero emissions (defined as a final disposal rate of less than 0.1%) until FY2020 through the reduction, reuse, and recycling of industrial waste.

Final disposal rate of industrial waste at production plants: 0.3%
Third-party assured

Although we managed to reduce emissions and made progress on the final disposal rate, we missed our target as there remained scope in some cases for further recycling.

△
<Industrial waste 2>
(1)Maintaining of recycling rate for construction waste at 98% or above
*
We will maintain the recycling rate for construction waste generated from business activities by our company and its subsidiaries at 98% or above until FY2020.

(2)Recycling rate for industrial waste generated at offices: 88% or above* 
We will achieve a recycling rate of 90% or above for industrial waste generated at offices of our company and its subsidiaries by FY2020.

(1)Recycling rate for construction waste: 97.8%
Third-party assured

The target recycling rate was missed due to unexpectedly high emissions of sludge, which has a high reduction rate (low recycling rate).
The final disposal rate for construction waste was 0.8%.

(2)Recycling rate for industrial waste generated at offices: 86.7%
Third-party assured
The target recycling rate was missed due to low emissions of highly recyclable construction rubble.
The final disposal rate for industrial waste generated by offices was 5.2%.
△
△
<Excavated soil>
Reduction of the amount of excavated soil from gas pipeline construction to 16% or less
*
We will work to reduce, reuse, and recycle excavated soil arising from roadside construction work ordered by our company and its subsidiaries. Through these efforts, we will maintain the amount of excavated soil at 16% or less until FY2020.

Reduction of the amount of excavated soil from gas pipeline construction to 16.5%
Third-party assured
We improved on the previous fiscal year by holding emissions down to 16.5% of the amount that it is estimated would have been generated had no action been taken. This was achieved by reducing the amount of soil excavated through shallow-laying of pipes in narrow trenches and use of non-open-cut construction methods, as well as by reburying excavated soil and increasing the use of improved soil and recycled road surface materials. However, we still fell short of our target due to an increase in cases in which excavated soil could not feasibly be reburied.
