「Release of the Guidelines for Harmonizing Marine Litter Monitoring Methods Using Remote Sensing」 - 2021.07 Service Initiatives Introduction CCUS(Carbon dioxide Capture, Utilization and Storage) “Asia CCUS Network” has launched
Mr. Kajiyama, Minister of Economy, Trade and Industry of Japan announced the launch of the ”Asia CCUS Network (ACN)” in the 1st Asia CCUS Network Forum held on June 22nd and 23rd. ACN is an international industry-academia-government platform aiming at knowledge sharing and improvement of the business environment for utilization of carbon capture, utilization, and storage (CCUS) throughout the Asia region. The secretariat of ACN is Economic Research Institute for ASEAN and East Asia (ERIA). 13 countries (all ASEAN member states, Australia, USA and Japan) and more than 100 companies, research institutions, and international organizations, including JGC Holdings and JAPAN NUS (JANUS) from JGC group, have so far expressed their intention to participate in the network.
Ministers of each country made a welcome speech for ACN in the forum. In their speech, development of CCUS technologies was highly expected as a solution for decarbonization because most of Southeast Asian countries need to continue depending on fossil fuels. In the session of “Japan CCUS showcase” on the second day, Mr. Kudo, general manager of JANUS, made a presentation regarding Gundih CCS project.
Potential maps in ASEAN Region
JANUS made some proposals and advices to METI before the launch of ACN. As a first step of their program, JANUS surveyed three countries (Viet Nam, Malaysia, Indonesia) and visualized the results by creating the Asia CCUS Potential Maps. The maps provide information about major CO2 emissions sources, possible storage areas as well as gas pipelines to perform preliminary evaluation of CCUS feasibility. The maps are available on the ACN website.
JANUS would like to propose further development and expansion of the CCUS potential maps and contribute to the progress toward CCUS project deployment in the ASEAN region including Gundih CCS project by JGC group.

Carbon dioxide capture and storage (CCS) - 2020.09 Service Aomori Office moved on September 1st, 2020.
The new address of Aomori Office is as follows:
353-1 Aza Nozuki, Obuchi, Rokkasho-mura,
Kamikita-gun, Aomori 039-3212 - 2020.05 Service Adoption of the City-to-City Collaboration Toward Zero-Carbon Society Projects in Indonesia, Maldives, and Malaysia JANUS, Toyama City, and private companies in Toyama City jointly proposed the projects below and were selected by the Japan Ministry of the Environment (MOE) to conduct the “City-to-City Collaboration Toward Zero-Carbon Society Projects in 2020.”
- Indonesia: “City-to-city collaboration project by Toyama City to realize SDGs future city for Bali Province and Semarang, Central Java Province”
- Maldives: “Support Project for Developing a Sustainable Eco-friendly Smart City: An Intercity Collaboration between Toyama City and Male’ City”
- Malaysia: “Decarbonized city building project through the construction of a decarbonized transportation system using biofuel and the dissemination of renewable energy”
Toyama City’s policy planning and decision making revolves around sustainable city management based on compact urban development centered on public transportation—resulting in their renown environmentally advanced city status, as an “environmental future city” and “SDGs future city.” In addition, to fulfill SDG goal 17, to strengthen and revitalize global partnerships, the City is collaborating with overseas cities to promote and disseminate environmental technologies and knowledge that housed within the City and companies with Toyama City.
For this project, JANUS will conduct studies on the applicability of decarbonization technology in five cities within three countries—Indonesia, Maldives, and Malaysia—in cooperation with Toyama City and Toyama companies with excellent decarbonization technology.
Indonesia:With the objective of reducing greenhouse gas emissions and developing a JCM Model Project in the province of Bali Province and Semarang City in Central Java, JANUS will examine fuel conversion businesses from diesel to natural gas and the expansion of renewable energy with a focus on solar power generation.
Maldives:With the goal of converting the Hulhumale area in Greater Male’, to become a “smart” and “compact” environment-friendly city, JANUS will examine low carbon public transport development projects, gas conversion projects for diesel power generation facilities, renewable energy/energy saving diffusion projects, and biogas power generation using organic disposal materials.
Malaysia:JANUS will examine low-carbon public transportation utilizing biofuels and diffusion of renewable energy centered on small hydroelectric power generation, aiming to achieve compact city development centered on public transportation in Iskandar, Johor, and Kota Kinabalu, Sabah, Malaysia. JANUS will also consider using bio-gas liquefaction technology that JGC Global Co., Ltd. is looking to develop as a low-carbon public transportation option utilizing biofuels.
In developing countries with advancing economies, it is apparent that increased urban population is leading to urban problems such as increase in traffic congestion, greenhouse gas emissions, and air pollution. In order to solve these problems, it is necessary to deploy Japan’s excellent decarbonization/low-carbon technology and policy knowledge and know-how as a total package.
In collaboration with Toyama City and companies in Toyama City, and utilizing the JGC Group’s technical capabilities, JANUS will accelerate activities toward developing overseas projects using this survey as a springboard and present valuable solutions for global environmental problems.
 
- 2019.06 Service Signing of Memorandum of Understanding (MoU) between Institut Teknologi Bandung (ITB) and JAPAN NUS Co., Ltd. (JANUS) The Institut Teknologi Bandung (ITB) and JAPAN NUS Co., Ltd. (JANUS) agreed to build a partnership by signing a memorandum of understanding on the “Realization of Regional CO2 management in Indonesia.”
ITB, a state-owned university, leads the Center of Excellence (CoE) of CCS-CCUS in collaboration with the Directorate General of Oil and Gas (Ditjen Migas), Ministry of Energy and Mineral Resources Indonesia, and other institutes, to undertake projects in Indonesia, associated with Carbon Capture and Storage (CCS) and Carbon Capture, Utilization and Storage (CCUS) including Carbon Dioxide Enhanced Oil Recovery (CO2-EOR).
JANUS is conducting research to promote the concept of regional CO2 management based on hub and clustering CO2-EOR in Indonesia. A successful implementation of the concept will make CCUS businesses economically feasible by connecting several CO2 sources and sinks such as oil and gas fields via a trunk a CO2 trunk pipeline.
Based on the MoU, ITB and JANUS will closely work together to deploy regional CO2 management in Indonesia.
As the very first partnered project under this MoU, ITB and JANUS organized the Indonesia-Japan CCUS Symposium on March 14, 2019 at the Ditjen Migas auditorium, in collaboration with Fukada Geological Institute and JGC Corporation, supported by the Ministry of Energy, Mineral Resources of Indonesia and Ministry of Economy, Trade and Industry of Japan and other institutes from both countries.
The symposium attracted 50 participants from the government, industries, and academics in both countries, and the two countries reinforced continued partnership towards the deployment of regional CO2 management in Indonesia. JANUS will contribute to this endeavor based on its technical experience and expertise and plan to strengthen its environmental consulting business.

- 2020.01 Events & Seminars Participated in the 25th session of the Conference of the Parties to the UN Framework Convention on Climate Change (COP25)
Participated as a member of the Polish delegation at the 25th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP25) in Spain on 2-15 December 2019. The venue for COP25 was Feria de Madrid (IFEMA), located near the international airport in the Spanish capital, Madrid.
According to news reports, the number of participants at COP25 was 27,000. And the interest was high even though the location was suddenly changed due to antigovernment demonstration in Chile. On the other hand, perhaps due to the change of venue, etc., there was noticeable empty space in the event hall, and it was felt that there were officials who could not make preparations in time.
COP25 Main venue(Madrid, Spain)COP25 Results
The main agenda in COP25 was “Can we determine the bylaws of the Paris Rule Book (especially those relating to Article 6 international trade) with the Paris Agreement coming into force?” “Also, can we further increase each country’s 2030 Nationally Determined Contribution (NDC) to achieve the 1.5 °C scenario?” As already reported in the press, the session was extended by two days but agreement on important points has been postponed and it cannot be denied that the results were iridescent. During the negotiations, no action was taken by India, Brazil, or China to find a way out of the measures, and European countries and other countries did not find a compromise. With the US Trump administration announcing the withdrawal of the Paris Agreement, it is undeniable that political pressure on developing countries has weakened. It is thought that harsh demands from other countries for further increasing the reduction target were reported to Japan, and that the coordination of the negotiating squad was extremely difficult.
The next COP26 will be held in Glasgow, Scotland in November 2020.
COP25 Plenary hall
From now on
Whether the NDC reduction target can be raised in the five-year review and whether the detailed rules of Article 6 of the Paris Agreement can be agreed will be a major discussion at COP26. On the other hand, rising calls for tighter regulation on coal and rising protests against the climate change issues of the younger generation, symbolized by the “ Friday for Future, “ may affect Japan’s climate change policy. It is necessary to watch closely..
