Total greenhouse gas emissions (non-consolidated + main consolidated subsidiaries) for the Group in fiscal 2022 was 10,487 thousand tons. Which was a decrease of 166 thousand tons compared to fiscal 2021.
In fiscal 2022, our non-consolidated greenhouse gas emissions from energy sources were 3,114 thousand tons. It decreased by 43 thousand tons compared to fiscal 2021.
* Greenhouse gas emissions derived from non-energy sources comes mainly from limestone, which is used as a raw material. As it is difficult to substitute or reduce volumes of limestone, however, our emissions target covers greenhouse gas emissions derived from energy sources, which can be reduced by energy saving initiatives.
Greenhouse gas emissions on a non-consolidated basis were reduced by 70 thousand tons CO2 (1% reduction) compared to fiscal 2021. Emission intensity improved significantly due to the impact of the increase in production volume for each business and the increase in the use of thermal energy alternatives such as waste plastic and recycled oil at cement plants.
Energy consumption by Mitsubishi Materials decreased 0.2% year on year. In addition, emission intensity improved 4.5% with the impact of the increase in production volume for each business and the increase in the use of thermal energy alternatives at cement plants. Business Operator Classification Evaluation System : S class (S class: improvement of basic unit of 1% or more on average over the past 5 years).

| Category 4 |
Transportation and distribution (upstream) | Same as organizations covered by environmental data other than greenhouse gas emissions | 617 | 1,374 | 1,992 | 1) Emissions from the physical distribution of products and services, which were purchased in the reportable fiscal year, from suppliers to the company ・A transportation scenario was set for each major raw material (excluding waste as raw materials and by-products as raw materials). ・Distances between countries were set using the IDEA database on distances between countries, and other distances were set using a distance search site (with distance given by an in-house company in a questionnaire adopted in some cases). 2) Emissions from the physical distribution of products that were shipped and transported in the reportable fiscal year at the expense of the company ・A transportation scenario was set for each major shipped product. ・Distances between countries were set using the IDEA database on distances between countries, and other distances were set using a distance search site. |
| Category 5 |
Waste generated from operation | Same as organizations covered by environmental data other than greenhouse gas emissions | 2 | 8 | 10 | The amount of industrial waste (waste recycled into resources and landfilled waste) was included. |
| Category 6 |
Business trip | Consolidated | 0 | 3 | 3 | For Mitsubishi Materials (non-consolidated), the number of employees at each base (plants and offices) was used for the calculation. However, in consideration of the voluntary restraint on business trips for controlling the spread of COVID-19, travel expenses in the reportable fiscal year were compared with those in a normal fiscal year, and the value obtained by multiplying the number of employees by the ratio of travel expenses in the reportable fiscal year to that in a normal fiscal year was regarded as the value for the amount of activity. For consolidated subsidiaries, the number of employees of each in-house company from human resources information given in the securities report was used for the calculation. |
| Category 7 |
Employee commute | Consolidated | 2 | 9 | 11 | For Mitsubishi Materials (non-consolidated), the number of employees at each base (plants and offices) was used for the calculation. For the head office and other offices, however, in consideration of the voluntary restraint on going to workplaces to control the spread of COVID-19, the value obtained by multiplying the number of employees by the rate of employees who commuted to work for the reportable fiscal year was regarded as the value for the amount of activity. For consolidated subsidiaries, the number of employees of each in-house company from human resources information given in the securities report was used for the calculation. |
| Category 8 |
Leased assets (upstream) | ー | ー | ー | ー | While there are leased assets, they were excluded from the calculation because they are included in Scope 1 and Scope 2. |

Transportation and distribution (downstream) | Same as organizations covered by environmental data other than greenhouse gas emissions | 126 | 289 | 415 | Emissions from physical distribution of products that were shipped and transported to sales destinations at the expense of other companies Transportation from sales destinations to final consumers was excluded. Distances between countries were set by using the IDEA database on distances between countries, and other distances were set by using a distance search site (with the distance given by an in-house company in a questionnaire adopted in some cases). |

Fabrication of sold products | Same as organizations covered by environmental data other than greenhouse gas emissions | 215 | 501 | 717 | For products sold, the value for the amount of products shipped by each in-house company to companies other than group companies was regarded as the value for the amount of activity. Emissions from processing were calculated by setting the primary processing assumed for each product. |
| Category 11 |
Use of sold products | ー | ー | ー | ー | Products sold were excluded from the calculation because they are materials and parts that are used by a wide range of users and it is therefore difficult to follow their paths to final products. |

We regard it as a top priority to save energy wherever possible at our manufacturing facilities and plants. That is why we are so committed to energy saving activities. Specific activities include switching fuels, making effective use of untapped energy, upgrading processes and equipment, installing high-efficiency equipment, optimizing device specifications, and reviewing equipment controls and operating practices. We are constantly working to save energy at smaller facilities, too, including Head Office, branches, sales offices and research facilities, through measures such as installing LED lighting.
Our CO2 emissions from transportation for fiscal 2022 totaled 18,534 tons for Mitsubishi Materials*1 (up 1,443 tons from the previous fiscal year), and 30,237 tons in total including emissions from group companies*2 (up 981 tons from the previous fiscal year). Meanwhile, energy consumption per unit*3 came to 21.47 kiloliters per million ton-kilometers for Mitsubishi Materials, which was 0.4% better than the previous fiscal year.
We will continue to promote a modal shift with a focus on long-distance transport and optimize logistics throughout the Group in our efforts to build a logistics system with low environmental impact.
