１．Background
The movement toward carbon neutrality is accelerating around the world. As of
September 2021, 123 countries and regions have committed to virtually zero
emissions of carbon dioxide or greenhouse gases by 2050. China, the world's
largest emitter thereof, has also announced that it will achieve virtually zero
emissions of greenhouse gases by 2060.
The challenge is not a cost to economic growth, but a growth opportunity for atransformation of industrial structure, economic and social reform, and investment.
The world has entered a new game-changing era.
It is a great opportunity for many Japanese companies skilled at energy-saving
technology to improve their presence in the world. In order for Japanese companies
to take advantage of this opportunity, it is essential to understand patent
information closely related to innovation.
On the other hand, Japanese companies are underweighting in ESG investment
universe. The Government Pension Investment Fund (GPIF) has published acountry ranking of ESG investment in its ESG Activity Report FY2020. Japan's ESG
country ranking is lower than those of developed countries and the degree of
improvement is not high in both the FTSE and MSCI methodologies of the report2.
While there might be many reasons for the ESG discounting of Japanesecompanies, the following two points are the most important.
 Although it is essential for many Japanese companies, which have highreputation for manufacturing, to present their own technologies to investors,
their information disclosures are not enough for the global investors.
 ESG evaluation organizations are mainly US or Europe ones and they gather
invest information in English. Japanese companies, especially small andmedium-sized enterprises (SMEs), do not disclose enough information in
English3. Therefore, a language barrier works against Japanese companies.
The author believes that one of the factors to solve the above issues is to use
patent information.

It is essential for companies as investment targets to disclose objective
information about themselves (in English, if possible) to investment trustees andasset owners. In addition, ESG investments are characterized by a longer
investment period than other types of investments. Then, ESG investments andpatent information have a high affinity in the following respects.
 Because patents are valid for 20 years from date of filing application, a patentapplication suggests that a company can possese the particular technology fora long time.
 Because application formats of various IP Offices is standardized and the qualityof machine translations in the patent field is high4, it is possible to analyze thetechnology level of companies as investment targets on a global level, checking
even non-English patent information such as Japanese and Chinese.
 The AI model of "Visualization of decarbonization patent technologies" by Japan
Patent Information Organization (Japio) can select and disclose only relevant
patent applications of noteworthy decarbonization technologies from a vast
amount of patent information.
Japan Patent Information Organization (Japio) has various activities based on its
philosophy "contributing to the economy and society by providing high-quality
patent information”. In 2021, the Japio AI Research Center has successfully
established an AI model to estimate patent applications related to decarbonization
technologies from patent specifications.
In this report, Japio investigates trends in PCT, US, CN, and DE patentapplications by Japanese companies for decarbonization-related technologies,
using Japio’s AI model of decarbonization technologies. This report shows
Japanese companies as “Green Enablers 5 ” that can show their technicalpresence in major countries. Moreover, it shows that there is a great potential
for Japanese companies to contribute to environmental protection on a global scale.

２－１．Data
Data of patent gazettes published between January 1, 2021 and December 31,
2021 for PCT international applications (WO), applications to the USPTO (US),applications to the CNIPA (CN), and applications to the DPMA (DE) were extracted
from Japio-GPG/FX 6 . The data were analyzed for decarbonization technologies
using the Japio’s AI models.
The search query in Japio-GPG/FX is as follows. (Data extraction date: March 3,2022.)

the above-mentioned patent gazettes. The model estimates the technology type8
and calculates its estimated value. The estimated value ranges from 0 to 1. The
closer the value is to 1, the higher the certainty of the estimate is. The values arecompiled as a “score” for each company.

The estimation results were aggregated by applicant, and the "JapioDecarbonization Patent Index" was calculated as the ratio of the number of patents
estimated as decarbonization-related technologies to the total number of patents.

8

we compiled each estimated patent document into three fields of “Energy-related industries“, “Transportation/manufacturing-related industries," and “Household/office work-relatedindustries “. These fields are described as the important fields where growth is expected inthe "Green Growth Strategy through Achieving Carbon Neutrality in 2050"*3 (June 18, 2021)
released by the Cabinet Secretariat.
https://www.meti.go.jp/press/2021/06/20210618005/20210618005-3.pdf
9Since there are multiple applicants with the same number of patent applications, thenumber of applicants to be analyzed is slightly higher than 2.5% of the total.
10

Since the applicant's name cannot be fully corrected, the actual number of applicants is

expected to be less than these figures.

The closer the index is to 1, the more decarbonization-oriented patentapplications are filed by this applicant. In this report, we have selected Japanesecompanies with a high index. For more information on the "Japio-Decarbonization
Patent Index", please see the URL below.

３．Rankings of “Green Enablers” in 2021
Various rankings are shown below. In these rankings, Japanese companies areshown in red. In addition, only Japanese companies with a high index are shownin “Green Enablers” rankings by “Japio-Decarbonization Patent Index”.
The "applicant name" shown in the table below is the name of the applicant
described in each patent publication. Applicant names that are considered to be
the same but whose characters do not match due to abbreviations or misspellings
are corrected. (Did not correct names of companies belonging to the same
corporation group.)

The results of PCT international application (WO)
In general, companies tend to file PCT international applications for technologies
that they plan to use in many countries. There are also many studies showing thatthe size of the number of patent families and the geographic scope of patent
protection are related to the patent value. Thus, PCT international applications can
8be an indicator of patent technologies that a company considers important andvaluable.

The results of applications to USPTO (US)The nominal GDP of the U.S. in 2020 was 20,893.750 (USD)11, the highest in theworld. According to the JPO's Annual Report 2021 12 , the number of patentapplications on a filing basis in 2019 was the second highest (621,451), after China(1,400,661).
Of the applications to USPTO, the largest number of applications from abroadcame from Japan (14%13 of the 2019 application base). Although the number ofapplications from China has increased dramatically in recent years, Japaneseindustry currently possesses more patents, a powerful business resource, in the
U.S. market than any other foreign country. Therefore, in order to survive andgrow in the U.S. market, it is extremely important for Japanese industry tounderstand effective and strategical use of patent rights14.

Patents data of the PCT international applications, applications to the U.S.,
China, and Germany, published in 2021, were analyzed for visualizing
decarbonization (Carbon Neutrality) technologies using Japio’s AI models, and theresults were compiled to company level in order to see who the “Green Enabler”
is.
In the rankings of “Green Enablers”, a company having decarbonization-related
patents, in 2021, the number of Japanese companies in the top 20 was relatively
high, comparing to the top 20 with the most applications. (See red number inTable 1)

The ranking of “Green Enablers” is a quantitative indicator of their R&D
capabilities in decarbonization technologies. On the other hand, “Green Enablers”
ranking by “Japio-Decarbonization Patent Index” is an indicator of how acompany’ R&D is directed to decarbonization. From Tables 1 and 2 above, it isclear that Japanese companies are actively engaged in R&D and patentapplications for decarbonization technologies in major countries, both in terms ofquantity and directivity.
This is obvious evidence that many Japanese companies have the potential todevelop technologies to solve the environmental changes that are becoming asocial issue around the world, and the implementation of such technologies insociety is eagerly awaited. For this purpose, they should present such evidence toglobal investors to alleviate the ESG discounting problem as described in "1.
Background”.

The number of applications filed in 2019 (or 2020) by each patent office, and the number

and percentage of applications filed by Japanese company, are as follows. If the ratio (C/Z)
in Table 2 is more than 1, it means more Japanese companies with high decarbonized patentindex in the country. Please note that, because C is based on the number of patents andcompanies, and Z is based on the number of applications filed annually, it cannot be simply
compared.

In order to achieve the mid- and long-term goals of a decarbonized society, it isimportant for each government to create an environment, both institutional andfinancial, that encourages companies mentioned in this report, with thetechnological potential, to apply patents and implement these decarbonizationrelated technologies in its country.
For example, in terms of intellectual property, it is expected to researchtechnological trends to identify which companies and universities have seeds thatcan contribute to decarbonization, and to establish a framework to promote
cooperation among companies by utilizing these intellectual property rights.
