CO₂ FREE (Realization of a Carbon-neutral Society)

In October 2020, the Japanese government declared its target of achieving carbon neutrality by 2050, to this end raising its fiscal 2030 reduction target for CO₂ emissions from 26% to 46% (both compared with the fiscal 2013 level) in April 2021. This is but one example of decisions made by countries around the globe amid the accelerating trend toward across-the-board decarbonization and the realization of a low-carbon society.
　Toward achieving the CO₂-free target set out in the Kawasaki Global Environmental Vision 2050, the Kawasaki Group is not only actively engaged in realizing carbon neutrality at its plants (Scope 1 and 2) but also throughout its supply chain (Scope 3).

Efforts to Achieve Zero CO₂ Emissions—Carbon Neutrality Targets (Medium- to Long-term Targets)

Toward achieving the CO₂-free target set out in the Kawasaki Global Environmental Vision 2050, the following CO₂ emission reduction targets have been set for the years 2030 and 2040.

Corresponding companies: Kawasaki Heavy Industries, Kawasaki Railcar Manufacturing, Kawasaki Motors + Affiliated companies in Japan

To reduce Scope 1 and 2 CO₂ emissions, the Kawasaki Group will first create zero-emissions plants in Japan, which accounts for three-quarters of the Group’s total annual emissions of 400,000 tons, by combining power generation from waste, renewable energy, and other sources with a focus on in-house hydrogen-fueled power generation facilities, as described below. We will then expand implementation to overseas subsidiaries and promote the introduction of hydrogen energy to existing power generation facilities previously delivered to customers and other facilities.
　The natural gas-fired gas turbine facilities previously delivered by the company that are in operation as of 2022 have a total capacity of about 1,000 MW. If we make proposals for the introduction of hydrogen energy and are able to transition these facilities to mixed hydrogen or exclusive hydrogen firing, it will be possible to shift to hydrogen energy without making substantial changes to existing facilities.
　Hydrogen power generation is currently advancing from the verification stage to the commercial application stage, and one urban area that can serve as a model, we have already achieved supply of heat and electric power generated exclusively from hydrogen using gas turbines manufactured by Kawasaki Heavy Industries.

Scope 3 Net Zero can only be achieved when all parties in the value chain including trading partners and clients become Zero-Carbon Ready. The Company will implement the maximum possible measures concerning Scope 3 to become Zero-Carbon Ready by 2040. Specifically, for category (i), we will slash CO₂ emissions by suppliers of materials and parts by 80%, and for category (xi), we will develop a lineup of CO₂-free standard solutions in all businesses. Moreover, we will reduce CO₂ emissions by more than the Company’s own Scope 3 emissions by working toward achieving a hydrogen-based society and engaging in the CCUS business, thereby contributing to the early achievement of carbon neutrality around the world.

Scope 3 Breakdown by Categories

^* Regarding Category (xi) in Scope 3, from fiscal 2022, the scope of calculation was expanded from a total of KHI, KRM, and KMC, to the Kawasaki Group.

Support industrial initiatives with hydrogen and CCUS solutions to further accelerate reductions

It is anticipated that many industries and companies will tackle the reduction of CO₂ emissions through various measures, including the utilization of renewables and efficient energy use.
　The Company will deepen its partnerships, including sharing emissions data with business partners, offering support for CO₂ reductions and striving for early achievement of zero emissions. This will be achieved by means not limited to in-company utilization by the Group of solutions such as hydrogen power, hydrogen fuel, and other alternative fuels, as well as CCUS, but also by providing these solutions to business partners that supply materials and parts.

Scope 3 Category (i) (CO₂ reductions scenarios)

Provide CO₂-free solutions to all customers

The Group will actively further three major initiatives. The first will be the provision of CO₂-free fuels and electrical power to society, with a focus on its hydrogen business. The second will be to make a selection of choices for electrification and CO₂-free fuels available to customers utilizing our various solutions including mobility and robots. The third will be to undertake initiatives to provide CCUS solutions to capture CO₂ emitted into the atmosphere, and subsequently store underground or use this CO₂.
　With these three pillars, the Group will make choices available to our customers of products and services (excluding defense and related; emergency products business) that contribute to the achievement of carbon neutrality by 2040, and promote global reductions in CO₂.

^* From fiscal 2021, the Group modified its calculation method to allow more accurate records of emissions levels for Scope3 category (xi).
　Previously, CO₂ emissions levels for products such as hydraulic machinery, manufactured as parts to be incorporated in finished products, were calculated by tallying the CO₂ emissions levels of the finished products such as construction machinery. However, from fiscal 2021, these calculations will also take into account the degree of contributions and weight ratios for final products.

Environmental Management Activities Plan 2022 (Short-term Target and Plan)

Aiming to achieve its carbon neutrality target (medium- to long-term target), in the short-term, while the Company will step up efforts to introduce in-house hydrogen power generation by 2030 to achieve carbon neutrality at its plants (Scope 1 and 2), it will continue its ongoing efforts to scale the introduction of renewable energy and to save energy. Furthermore, the Company will accelerate these efforts with the introduction of internal carbon pricing.
　To achieve carbon neutrality of its supply chain (Scope 3), the Company aims to realize Zero-Carbon Ready by 2040 by advancing its provision of CO₂-free solutions to its business partners and customers. At the same time as Scope 3 reductions, the Company will also publish its CO₂ emissions through product-based contributions (= calculation of avoided CO₂ emissions through the selling of products and services that generate less CO₂ emissions than previous products and services).

As a measure to promote energy-saving activities, in 2022, the Company introduced an initiative to set reference values for the CO₂ reduction efficiency of energy-saving investment projects as criteria for determining the investment in such projects and to increase the equipment budget allocation for projects in which the reduction efficiency meets the criteria. Through this initiative, the Company will continue to reduce its CO₂ emissions by advancing its investments in equipment with a focus on projects with a high CO₂ reduction efficiency. Such equipment investment projects include upgrading production equipment, switching air conditioning systems to those that run on electricity, and changing to LED lighting.

To promote investment in carbon neutrality efforts such as the introduction of future hydrogen equipment and renewable energy and to change behavior within the Company, in fiscal 2022, the Company introduced internal carbon pricing.
　The outline of the program is to charge a carbon surcharge for the emissions of Scope 1 and 2 of the previous fiscal year by Kawasaki Heavy Industries, Kawasaki Railcar Manufacturing, and Kawasaki Motors by calculating the surcharges of each company using a CO₂ unit price. The aim is to make concentrated investments in carbon neutrality efforts based on the funds generated from internal surcharges of the internal carbon pricing program.
　The CO₂ unit price is set at 2,000 yen/t-CO₂.

Nearly 90% of CO₂ emitted during the life cycles of our products is released during the period of their use after they are sold. Therefore, the Company seeks to realize a carbon-neutral society by providing products that produce only low CO₂ emissions during their use. To reduce products’ post-sale CO₂ emissions, in addition to increasing product energy efficiency, we are advancing electrification and modal shifts when replacing existing products in our product lineup and expanding our lineup of products that utilize exhaust heat, waste, and renewable energy. Key products that help reduce CO₂ emissions are listed below. In fiscal 2017, we revised our rules for calculating CO₂ emissions reductions through product-based contributions in order to better quantify the contributions of such products to the mitigation of global warming.
　Calculations based on these rules showed that the CO₂ emissions reduction^* through products we sold in fiscal 2022 was about 24.37 million tons. Large contributions were made mainly by the M7A Series gas turbines for power generation, which boast excellent reliability, economy, and environmental friendliness and are certified under the Kawasaki Ecological Frontiers system, an internal certification program for environmentally conscious products, and the KC-MB-20, a controller for use in construction machinery to improve its fuel efficiency via the application of superior controlling technologies.

^* Reduction in CO₂ emissions compared to earlier products (refer to the calculation rules below.)

*1 CK Mill: Named after the companies that jointly developed it, Chichibu Cement Co., Ltd. (now Taiheiyo Cement Corporation) and Kawasaki.

*2 Developed with a focus on three Es: energy saving, easy maintenance, and environmentally friendly.

*3 Ship Operation and Performance analysis support system

*4 Environmentally Friendly Advanced Commuter & Express train

Calculation Rules

• Products to be assessed: Kawasaki Ecological Frontiers system, products that use waste, waste heat, and renewable energy, as well as cogeneration systems and rolling stock pertaining to modal shifts, etc., were selected for assessment
• Period of assessment: Until fiscal 2016, we used a one-year period of assessment. However, in line with the revision of the calculation rules, since fiscal 2017, we have adopted a flow-based approach* in which the period of assessment is the estimated useful life of products sold in the fiscal year, because the estimated useful lives of our products are long. This allows us to better calculate the difference in CO₂ emissions between our products and industry standard class products over the entire period of use.
• The calculation method expressed as a calculation formula is as follows: CO₂ emissions through product-based contributions = (annual CO₂ emissions from conventional products - annual CO₂ emissions from new products) x (assumed number of usage years)

^* Please refer to the "Guideline for Quantifying Greenhouse Gas Emission Reduction Contribution" (Ministry of Economy, Trade and Industry, March 2018)

In order to quantify the contributions of highly energy efficient products to the mitigation of global warming, products included in the calculation of CO₂ emissions reduction through product-based contributions include power generated through waste heat, waste, renewable energy, and so forth. As a result, some of the products included differ from those included in the calculation of Scope 3, category (xi), which covers only energy-derived CO₂ emissions.
　CO₂ emission reductions for the past five years are shown in the graph below. Particularly notable products that have had a large cumulative effect are shown below.

• Notes: 1. Kawasaki uses CO₂ emissions factors provided in the list of calculation methods and emissions factors published by Japan’s Ministry of the Environment.
• 2. The CO₂ emission reduction effect through product-based contributions achieved through the higher energy efficiency of products is based on a comparison using industry standard products.
• 3. The application of waste heat, waste, and renewable energy is counted toward the CO₂ emissions reduction effect through product-based contributions.

External Affairs Activities Concerning Climate Change

To contribute to realization of a society that limits the increase in the global average temperature to 1.5℃ compared to pre-industrial times, the objective of the Paris Agreement, the Kawasaki Group is using its technological knowledge and expertise relating to decarbonization, actively participating in trade association activities, and contributing to the formulation of policy recommendations concerning climate change mitigation and adaptation. The directors in charge of the relevant departments ensure that trade association activities and public policy engagements are in line with the Group’s strategies concerning responses to climate change and report as necessary to the Board of Directors, the highest decision-making body responsible for deliberating on and finalizing fundamental sustainability policies and basic plans for the entire Group.
　In cases where we identify substantial misalignments between the activities of organizations of which the Group is a member and the objectives of the Paris Agreement, we engage in constructive dialogue with those organizations based on the Group’s climate change strategy and business activities, and if those misalignments cannot be eliminated after the passage of a certain period of time, we consider appropriate responses including withdrawal.

Hydrogen, a source of clean energy that does not emit any CO₂ during use, has become a focus of attention as one solution for achieving a carbon neutral society by 2050. In response, the Kawasaki Group has positioned the achievement of carbon neutrality centered on hydrogen electricity generation as one pillar of our climate change strategy and is now working to carry out that strategy in collaboration with policymakers and trade associations.
　Group Vision 2030, our management strategy, positions new business including the hydrogen business as our primary growth scenario and seeks to achieve the 1.5°C target in line with the Paris Agreement. The hydrogen business in particular is positioned at the center of the Company’s business growth and transition plan, and we are actively cooperating with policymakers, industry organizations, and others to assess hydrogen GHG emissions and formulate international supply chain rules with the aim of achieving the objectives of Group Vision 2030 and carbon neutrality at an early stage.

In order to promote low-carbon hydrogen utilization in society toward the realization of a carbon-neutral society, it is necessary to evaluate the hydrogen to show that it is low-carbon, and it is ideal that the evaluation criteria are standardized internationally. The methodology for determining greenhouse gas (GHG) emissions of hydrogen is discussed in IPHE (International Partnership for Hydrogen and Fuel Cells in the Economy), an international inter-governmental partnership whose objective is to facilitate and accelerate the transition to clean and efficient energy and mobility systems using fuel cells and hydrogen technologies. Our company has participated in this discussion as an expert supporting the Ministry of Economy, Trade and Industry, Japanese government, and has made a significant contribution, including providing technical advice, particularly about liquefied hydrogen supply chain.

As a member of HySTRA (CO₂-free Hydrogen Energy Supply-chain Technology Research Association), the Company participates in efforts to build a CO₂-free hydrogen supply chain consisting of hydrogen production, transport/storage, and usage using lignite effectively, and works to establish and verify the relevant technologies to be commercialized by around 2030.
　The Company's role at HySTRA is to engage in building liquefied hydrogen carriers and constructing liquefied hydrogen unloading equipment and bulk storage facilities by utilizing the ultra-low temperature technologies it has developed such as for LNG carriers, LNG storage tanks, and liquefied hydrogen tanks for rocket fuel.
