Zeon Begins Energy Conversion Toward Achieving Carbon Neutralityby Shifting to 100% Renewable Energy for All Purchased Electricity at Four Domestic Business Sites
Zeon Corporation
Zeon Corporation (President and CEO: Kimiaki Tanaka) has converted to 100% renewable energy*1 for all purchased
electricity at four of its production sites in Japan (Takaoka Plant, Himi Futagami Plant, Tsuruga Plant, and TokuyamaPlant) as of April 1. In addition, it has signed an agreement for purchasing carbon neutral LNG, which has the effect ofgenerating zero CO2 emissions, for the Takaoka Plant, and an agreement for purchasing Green Heat Certificates*2 toreduce CO2 emissions generated by steam used at this plant. Through these initiatives, CO2 emissions at the four sites
are expected to decrease by approximately 80,000 tonnes per year compared to levels in 2019, and Zeon intends tocontinue accelerating its efforts toward achieving carbon neutrality.
Zeon is working to realize carbon neutrality and a circular economy by promoting a transformation in its “monozukuri” as partof its strategies under the Medium-Term Business Plan launched in FY2021. One of the key measures is energy conversion, andconsideration had been underway to adopt renewable energy and fuel with non-fossil certificates*3 for replacing the fuel used
for facilities such as boilers, the source of energy generation, at each production base.
In the latest move, all electricity used at the three sites in the Hokuriku region (Takaoka Plant, Himi Futagami Plant, andTsuruga Plant) have been converted to energy with renewable energy certificates based on hydroelectric power generation,
through the introduction of the Kagayaki GREEN RE100 plan provided by the Hokuriku Electric Power Company. Theagreement, signed by the Takaoka Plant for purchasing carbon neutral LNG (liquefied natural gas), was the first sucharrangement between a general company*4 and the Hokuriku Electric Power Group.
Furthermore, the Tokuyama Plant has converted to renewable energy by introducing a plan (special agreement for renewableenergy) provided by Chugoku Electric Power Co., Inc. for all its energy needs and is also reducing its CO2 emissions bypurchasing Green Heat Certificates from Japan Natural Energy Co., Ltd.

Considerations are underway for converting to renewable energy at other production sites in Japan, and energy conversion isscheduled to take place at the Kawasaki Plant (Kawasaki City, Kanagawa Prefecture) in August. Zeon will continue striving toensure safe and secure operations while proactively working to achieve carbon neutrality and contribute toenvironmental sustainability along with safe and comfortable living.

1-6-2 Marunouchi, Chiyoda-ku, Tokyo 100-8246 Japan*1 Renewable energy:
Electricity derived from renewable energy sources such as hydro, solar, and wind power.
*2 Green Heat Certificate:This certificate embodies the environmental added value of green heat generated by “natural energy;” by purchasing thecertificate, the purchaser is deemed to have used green heat. The cost of the certificate is used for maintaining and expanding
natural energy projects, thereby contributing to the spread of renewable energy. Certificates are issued by a third-party
organization to ensure credibility.
*3 Fuel with certificates:
Fuels that offset greenhouse gases, which are generated in the process, from extraction to the burning of natural gas, and thatcarry a carbon credit (carbon offsetting). Thus, they are deemed to be carbon neutral on a global scale when used (equivalentto carbon neutral LNG in Zeon’s case).
*4 Company other than a city gas supplier.
