Response to the TCFD recommendations (Postal and Domestic Logistics Business and Post Office Business)

Scenario	Physical risks: IPCC RCP1.9 (1.5℃ scenario)/RCP2.6 (2℃ scenario)/RCP8.5 (4℃ scenario) Transition risks: IEA WEO NZE 2050 (1.5℃ scenario)/WEO STEPS (2.5℃-4℃ scenario)
Business covered	Postal and domestic logistics business and post office business
Period	2030 and 2050

The Group has assumed a scenario where the increase in temperature at the end of the century will be limited to 1.5℃ or less from the pre-industrial level, and a scenario where the increase in temperature at the end of the century will exceed 4℃ from the pre-industrial level, and analyzed the effects of the temperature rises on the postal and domestic logistics business and post office business in both scenarios*.

If RCP1.9 (1.5℃ scenario) does not include the parameters necessary for quantitative estimates of physical risks, the parameters of RCP2.6 (2℃ scenario) are used.

Risks and opportunities that climate change will present to the postal and domestic logistics business and the post office business, and their impact under the situations in the 1.5℃ scenario and the 4℃ scenario are as follows.

Physical risks: Acute or chronic damages caused by climate change disasters
Transition risks: Risks posed by changes in policies, regulations, technological development, market trends and evaluation in the market, for example, due to transition to a low-carbon economy

Classification of risks and opportunities		Expected period of materialization^*1	Financial impact^*2	Material risks and opportunities and expected impact (scenario analysis)
Physical risks	Acute	Short term	Small to large	There is a possibility that the flooding of a river and a storm surge will occur due to an increase in heavy rain in a short period of time and part or all of the post offices in the basin of the flooded river or the coastal area where the storm surge occurred will collapse or be damaged. Costs and time will be required to repair the post offices. In addition, there is a risk that the Group will be unable to continue the businesses due to damage to post offices and the disruption of roads, which could pose an obstacle to the provision of universal services and result in a decline in sales. [1.5℃ scenario] Given an increase in heavy rain, it is expected that the flooding of rivers, storm surges and mudslides will have a certain impact on post offices. [4℃ scenario] Given a significant increase in heavy rain, it could involve the collapse of post offices more extensively than the cases in the 1.5℃ scenario.
Physical risks	Chronic	Short term	Small to medium	The risk of heatstroke to employees working outdoors will grow due to an increase in the number of days with temperatures over 30 ℃ and over 35 ℃ caused by climate change. This will increase costs, such as personnel expenses. [1.5℃ scenario] The heatstroke risk of employees is expected to grow because the annual number of days with temperatures over 30℃ will increase along with a rise in the average annual temperature. [4℃ scenario] The heatstroke risk for employees is expected to grow significantly because the annual number of days with temperatures over 30 ℃ will increase remarkably along with a significant rise in the average annual temperature.
Transition risks	Policy and regulations	Medium to long term	Small to medium	If regulations on GHG emissions are introduced or tightened, costs may increase for the replacement of facilities and vehicles to reduce GHG emissions and energy consumption and to change fuels. If a carbon tax is imposed (credits are purchased) based on fossil fuel consumption, costs may increase. [1.5℃ scenario] It is assumed that the government will impose carbon taxes to reduce GHG emissions. [4℃ scenario] The Group thinks that the possibility of the introduction of carbon tax is low.
Transition risks	Reputation	Short to medium term	Small to large	If investors regard that we do not have a positive stance toward climate change measures, there is a possibility that they would cast their vote against the election of directors at a shareholders' meeting or that they would withdraw their investment from Japan Post Holdings. Also, customers may grow more aware of environmental issues and choose products, services, etc. with a smaller environmental impact while products, services, etc. that are regarded to lack an adequate consideration of the environment may tend to be avoided and their sales may drop.
Opportunities				The Group may increase sales by meeting the needs of customers (use climate change as a business opportunity). To meet customer needs, the Group may install more quick chargers for electric vehicles for local residents and develop and provide environmentally friendly delivery services and products. The Group may curb increases in costs (avoid risk) by renovating facilities and introducing and increasing the number of electric vehicles if a carbon tax is imposed (credits are purchased).

*1 Expected period of materialization: The Group divides the period of materialization into three categories: short term (a year or less), medium term (three years or less), and long term (three years or more).
*2 The Group presently divides financial impact into three categories: small (less than ¥1 billion), medium (¥1 billion or more, less than ¥10 billion), and large (¥10 billion or more). The Group will continue to analyze qualitative impact.

To understand the impact of climate change risk on the postal and domestic logistics business and post office business portfolio, we conducted scenario analyses mainly on the physical risks associated with increasing extreme weather and the transition risks associated with changes in policies and regulations.
As for the financial impact of physical risk, we conducted calculations using weather data, hazard maps and other materials disclosed by Intergovernmental Panel on Climate Change (IPCC) and other organizations, assuming that the business scale, facilities and number of employees will be mostly the same as they are now.
For the financial impact of transitional risk, also, we conducted calculations based on the forecast carbon prices, carbon emissions coefficients and electricity prices disclosed by the International Energy Agency (IEA) and others, assuming that the business scale will be mostly the same as it is now. Carbon prices are expected to be 130 USD/t in 2030 and 250 USD/t in 2050, based on the forecasts by IEA.

In the current calculation of the financial impact, among the risks associated with the postal and domestic logistics business and post office business, we selected the following as items for which the correlation is relatively clear among the data disclosed by the IPCC, IEA and other organizations and the said businesses, and conducted calculations based on certain assumptions.
Going forward we hope to expand the scope of quantified items and carefully examine the calculation results by carrying out further analyses.

**Physical risks**
Operating and recovery costs	Amount of loss when operations are disrupted due to damage from torrential rains and floods as a result of extreme weather and the costs required for recovery
Insurance premiums	Premiums for property insurance and personnel insurance caused by a rise in the rate of disaster due to increasing extreme weather
Decline in productivity of outdoor work	Impact in case of declining labor productivity due to an increase in extremely hot days (35℃ and higher)

**Transition risks**
Cost of fossil fuels	Impact of fluctuations in fossil fuel prices
Electricity costs	Impact due to fluctuations in electricity costs or increased air-conditioner use as a result of rising temperatures
Carbon tax	Impact due to the introduction of the carbon tax (Scope 1 and Scope 2)

Increased cost　 Decreased cost（Unit: 100 million yen）

Notes:
1. The above calculations apply to the postal and domestic logistics business and post office business of Japan Post Co., Ltd.
2. The above calculations represent a simulation of future risks using forecast data disclosed by IPCC, IEA and other organizations and are not meant as a business plan.
3. Calculations may fluctuate in the event that the data used as assumptions are revised or changed, and we will continue to reinforce our understanding of risks by reassessing the impact of climate change on our business portfolio.

The response policies for controlling the impact of climate change on the postal and domestic logistics business and post office business portfolio and creating new earnings opportunities are indicated in the following table. Going forward we will continue to consider and implement specific countermeasures based on these response policies.

Response policies

Physical Risks

Visualize the risks of torrential rains and floods and bolster resilience toward such risks

To provide universal service, the Group has more than 20,000 facilities throughout Japan.
When establishing post offices and other facilities, we use hazard maps and local disaster prevention plans to reduce the risk of damage from heavy rains and flooding and build resilience.
We have established and implemented concrete BCP measures to maintain postal and domestic logistics networks and post office functions, which are the foundation of the lives of people living in regional communities, even in the event of a disaster, and to quickly restore the functions even when afflicted with a disaster. (E.g., reviewing evacuation routes, conducting simulation drills of evacuation guidance and safety confirmation, confirming the safety of employees through a safety confirmation system)
For locations considered to be especially at high risk of flooding and key locations for maintaining postal and domestic logistics networks, we have been promoting measures against heavy rains and flooding, which have been on the rise in recent years, by installing waterproof panels and portable power generators and utilizing emergency power generators installed in the facilities.
In the event of a disaster, an emergency disaster control headquarters will be established, and the head office, branch offices and post offices will work together to gather information, ensure safety and facilitate rapid recovery.

Maintaining the productivity of outdoor work

We have been using various products to combat heat.
In FY2023, we distributed compression undergarments which absorb moisture and feel cool to areas that experience many extremely hot days.

Transition Risks

Strengthen the decarbonization of facilities and vehicles

Utilize storage batteries
- Based on a strategic alliance with the Chubu Electric Power Group to promote carbon neutrality, we installed solar power generation equipment and storage batteries at the Tenpaku Post Office, Aichi Prefecture to use renewable energy and optimize energy use.
- Based on cooperation to promote a carbon neutral society with PowerX, Inc., which manufactures and sells large-scale storage batteries, we are making preparations to introduce an electricity optimization service using the PowerX Mega Power large-scale storage battery at the Okayama Post Office (Okayama Prefecture).

Open +Eco Post Offices
- We are opening "+Eco Post Offices" that use CLT^* to reduce CO2 emissions during construction, store carbon through the use of wood materials and use renewable energy for a portion of the energy used.
  We opened six such post offices in FY2023 (14 opened in total).
  * CLT (Cross Laminated Timber): Thick wood panels made from gluing together layers of long planks of wood at perpendicular angles to each other to give them excellent strength and insulation, curbing the generation of CO2 compared with concrete and steel.
- We are also testing new initiatives, such as the introduction of heat utilization equipment using woody biomass (chip boiler) and a wall-mounted solar power system that can generate electricity during the snow season (FY2022 at Tohma Post Office, Hokkaido), and an air conditioning system that uses geothermal heat as part of the heat source for the heating and cooling system (FY2023 at Aeon Town Takanosu Post Office, Akita Prefecture).

Turn post office buildings into ZEBs
- At the Naha Higashi Post Office in Okinawa Prefecture, which is currently under construction, we will achieve the first ZEB (Nearly ZEB)^* certification for a post office by improving energy conservation through heightened thermal insulation of the building and the introduction of high-efficiency air conditioners, lighting and hot-water heaters, and installing a solar power generation system.
  * ZEB (Net Zero Energy Building): A building that aims to reduce the balance of the annual primary energy consumed in the building to zero, while providing a comfortable indoor environment. It is certified by a public institution.

Switch vehicles used for post and parcel deliveries to EVs
- At Japan Post, we are switching vehicles used to collect and deliver post and parcels to EVs. We plan to introduce 13,500 electric vans and 28,000 electric motorcycles by FY2030.
- We are also building facilities to enable us to use renewable energy to generate the electricity used to charge EVs.
Make essential transport carbon neutral
- At Japan Post, we are working with Japan Post Transport to introduce hydrogen-fueled fuel cell light-duty trucks (hereinafter, "FC light-duty trucks") and are conducting demonstration tests of renewable diesel fuel as part of our efforts to achieve carbon neutrality.

FC light-duty trucks	Service areas	Between Shin Tokyo Post Office, Tokyo International Post Office and post offices in the eastern part of Tokyo 23 wards (postal codes 10 to 15)
	Date of introduction	Thursday, November 30, 2023
	No. of vehicles	5
Renewable diesel fuel	Service areas	Between post offices in the western part of Kanagawa Prefecture (postal codes 24 and 25), starting from Kanagawa Nishi Post Office
	Date of introduction	Wednesday, May 24, 2423
	No. of vehicles	1

Opportunities

Create earnings opportunities that look toward a decarbonized society

Develop and expand products and services with high environmental quality that capture customer needs As an ethical product that is friendly not only to the environment but also to society and people, we sold Ethical "Furusato Kozutsumi" (Hometown Parcels) on a trial basis, which alleviates various burdens by (1) measures to prevent food loss through the use of substandard goods, (2) CO2 offsetting from production to shipment (offering of options) and (3) concentration of labor related to collection and delivery by consolidating product delivery times (work style reform).
As a result of the trial, we were able to identify customer needs, with around 60% of customers choosing CO2 offset products, and we found that the initiative can leverage the strength of post offices, which have real contact with customers. We plan to develop this into promoting the understanding of and disseminating the ethical concept and planning more products in the future.
- Products: Dried fish from Saga Prefecture, curry made of Saga beef
- Period of sale: Mid-April to mid-June
- Place of sale: Post offices in some areas of Tokyo

To build a system in which our sales staff understand and can explain the issues, including climate change risk, and our initiatives to shippers, and to promote understanding and awareness of sustainability-related initiatives, we have created a video for corporate sales staff and provided training, as well as exchanged sustainability-related information in cooperation with the corporate sales departments in some areas, in an effort to disseminate sales proposals from a sustainability perspective.

Management

Decarbonized management

Monitor GHG emissions of each product and service
As companies increasingly work to identify and reduce CO2 in their supply chains, we check and sort related information needed to calculate CO2 emissions from facilities and vehicles in order to calculate the CO2 emissions of each product and service.
Consider the adoption of Internal Carbon Pricing (ICP)
We are considering the adoption of ICP to further reduce CO2 emissions and reduce the burden of the future introduction of a carbon tax, and to promote the renewal of facilities and equipment and the adoption of renewable energy.
In FY2023, we raised awareness by listing ICP as a reference value when requesting decisions on related measures.
