Environmental Impacts of the Nittobo Group

The Nittobo Group manufactures a wide range of products by using natural resources and chemical substances as raw materials and consuming fuel and electric energy.
Major environmental impacts include carbon dioxide generated as a result of energy consumption, chemical substances that are discharged to the environment without being collected, and industrial waste that is simply incinerated or sent to external landfill sites. The Nittobo Group is striving to reduce environmental impacts by using resources in a reasonable way while taking the needs of the environment into consideration.

Range of Data Collection

The Nittobo Group conducts an environmental protection survey for its consolidated subsidiaries once a year.
The material balance presented here has been obtained by collecting data from Nittobo and its consolidated subsidiaries in Japan and abroad on environmental impacts (Data on certain items are not collected from some overseas business sites).

2. Amount of Scope 3 greenhouse gas emitted by the Nittobo Group

  • In fiscal year 2017, the Nitto Group started to calculate the amount of Scope 3 greenhouse gas emitted in its value chain. The results for fiscal year 2018 are as follows:
  Category
 Amount of CO₂ emitted
(t-CO₂)		 Calculation method
1 Category 1 Products and services purchased 121,975 Calculated by multiplying the purchase prices of the top 70% of products and services purchased by business sites by the CO₂ unit value stipulated in the guidelines
2 Category 2 Capital goods 25,116 Calculated by multiplying the amount of capital goods (buildings, structures, machinery, and equipment) by the CO₂ unit value stipulated in the guidelines.
3 Category 5 Waste 456 Calculated by multiplying the amount of each type of waste by the CO₂ unit value stipulated in the guidelines.
4 Category 6 Business trips 313 Calculated by multiplying the number of employees by the CO₂ unit value stipulated in the guidelines.
5 Category 7 Commuting to/from work 221 Calculated by multiplying the amount of transportation expenses paid by the CO₂ unit value stipulated in the guidelines.
6 Category 9 Transport and delivery (downstream) 3,785 Amount of CO₂ emitted as included in the periodic reports of specified shippers under the Energy Conservation Act.
  • * The amount of CO₂ emitted in each category was calculated with reference to the Ministry of the Environment's Green Value Chain Platform and other guidelines.
