Measures to Address Climate Change

What is Casio doing to follow up on the Paris Agreement?

The objective of the Paris Agreement is to keep a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius. To achieve that goal, the agreement set out the target of net zero emissions of greenhouse gases by the second half of this century.
In 2020, Casio revised its own medium- and long-term goals, aligning them with efforts to build a decarbonized society. The goal may need to be made even more ambitious in the future to realize a decarbonized society, and Casio will respond appropriately while keeping a close eye on trends in the international community.

Realizing a Decarbonized Society

Environmental Action Plan

Does Casio have an environmental action plan? If so, please describe the details.

After identifying material environmental issues, Casio established the Casio Environmental Action Targets to clarify its medium- and long-term numerical targets and the deadlines for implementation. The Group is carrying out a plan to achieve those targets using mechanisms based on an ISO 14001 environmental management system.

Environmental Management

Environmental Risk Prevention Measures

What kind of system does Casio have for managing environmental risk?

As part of risk management at facilities, each Casio production site and major office has established rules and procedures in order to minimize environmental risks. This is based on emergency preparedness and response, which is a requirement for ISO 14001 certification.
Casio conducts environmentally appropriate design assessments as part of its product risk management activities, and works painstakingly to confirm legal and regulatory compliance, verify usage of hazardous substances, adopt measures to conserve energy and resources, and ensure that environmental adaptations are made for the 3Rs (reuse, reduce, recycle).


What kind of initiatives does Casio have for making eco-products?

Casio is committed to the development of eco-products in terms of planning, design, and engineering, in order to minimize the environmental impact of its products. In 1993, Casio began product assessment evaluations to encourage the systematization of eco-products. Under this system, preliminary evaluations were made of new products for their impact on the environment, and products that passed the standards were certified as Casio Green Products.
In 2009, Casio began certifying Casio Green Star Products, which are products that received excellent evaluations. Then, in 2016, Casio began certifying Casio Super Green Star Products, which have even higher environmental performance.

Building a Recycling Society : Product Initiatives

Green Procurement and Green Purchasing

What is the status of green procurement at Casio?

Casio has implemented its Green Procurement Standards to comply with various regulations concerning chemical substances contained in products. The standards apply to all parts and raw materials that are included in products manufactured by its production sites.
Casio also manages the levels of chemical substances in components and raw materials as legally required. The Green Procurement Standards are regularly updated to reflect the latest environmental laws and regulations.

Environmental Compliance

Waste Reduction Measures

What is Casio doing to reduce waste emissions?

Casio’s production sites and main offices operate an ISO 14001 environmental management system and dispose of waste properly in accordance with local laws. Casio is strengthening both its initiatives to reduce the generation of waste and initiatives to increase its recycling rate.

Reducing and Recycling Waste

Recycling for Used Products

What kind of recycling efforts for used products are you carrying out?

Collection and recycling of printer toner and drum sets, ink ribbons for label printers, and leased units.
Casio started collection and recycling in 1999.

Collection and recycling of PCs and rechargeable batteries
With the enactment of Japan’s Act on the Promotion of Effective Utilization of Resources in April 2001, Casio set up a system for collection and recycling of PCs and rechargeable batteries.

  • Business PCs
    Casio collects and recycles business PCs, which are first collected at Casio’s recycling centers and then entrusted to a recycling company.
  • Rechargeable batteries
    Casio collects rechargeable batteries replaced by its service centers, and sends them to recycling companies designated by the Japan Portable Rechargeable Battery Recycling Center (JBRC).

What kind of recycling efforts is Casio carrying out for small electronic devices?

With regard to the recycling of rare metals contained in used small electronic devices such as cellular phones and digital cameras, Japan’s Act for Promoting Recycling of Used Small Electronic Devices came into effect on April 1, 2013 after a study group led by the Ministry of Economy, Trade and Industry and the Ministry of the Environment completed its work and collection trials were done by local governments.

Manufacturers are responsible for making their products easier to disassemble and are required to use recycled materials. Casio is conducting a review of its environmental design criteria while confirming industry association policy. As the Act applies to small devices, many Casio products will be affected, and Casio has been taking steps in partnership with the business sector. Casio cooperated in the production of the Recycling Design Guidelines for the Creation of Product Assessment Manuals by the Japan Business Machine and Information System Industries Association (JBMIA) in 2014. Casio’s approach to environmentally sound design standards are therefore incorporated into those guidelines.

Biodiversity Preservation

What is Casio doing to protect biodiversity?

Casio’s efforts to help preserve biodiversity began in 1994 with a G-SHOCK environmental collaboration product, the Dolphin and Whale Model, which celebrated its 25th anniversary in 2019.
Casio carries out activities based on its Biodiversity Guidelines, established in 2011. In 2015, focusing on indirect impacts in the supply chain, it established the Casio Group Paper Procurement Policy, under which it avoids purchasing paper products suspected of destroying forests with a high conservation value.
In 2017, Casio began shifting to certified paper for product catalogs in Japan and started conservation activities for rare plants and insects discovered in surveys of its business sites in Japan.
To enhance its support for nature conservation groups through collaboration models of watches, which began in 1994, in 2018 Casio launched employee participation in those groups’ activities as well as field activities such as Arakawa River Clean-aid and Casio Forest  mainly powered by employee volunteers seeking to deepen understanding of social issues related to biodiversity.

Disclosure of Environmental Information

Terms such as "environmentally friendly" often seem vague. Does Casio have standards for such terms?

In January 2008, the Japanese Ministry of the Environment issued its Guidelines for Environmental Representations (Eco-labeling) with the aim of providing environmental labeling information that is easy for consumers to understand. Based on this, Casio has prepared and is now implementing the Casio Environmental Labeling Guidelines.

Initiatives to Reduce Environmental Impact, Such as Use of Clean Energy (Renewable Energy)

Do you have a track record of introducing clean energy?


  • Since first launching the SL-801 solar-powered calculator in 1981, Casio has developed, manufactured, and sold numerous calculators, watches, and clocks powered by solar cells.
  • Some watch products use parts made with biomass plastic.
  • Plastic use was reduced by reviewing the plastic packaging previously used with general watch products and instead using packaging materials that are made primarily with recycled paper.


  • As just one example of renewable energy use in Casio’s business facilities, the energy-saving building newly constructed for Casio Europe (Germany) in January 2009 features an air conditioning system that uses geothermal heat.
  • Casio Thailand uses electricity generated with solar panels for a part of plant equipment.
  • The electricity used at the main sites in Japan (Casio Computer Co., Ltd. headquarters, Hamura R&D Center and Hachioji R&D Center, Casio Techno Co., Ltd. headquarters and Technical Center, Casio Marketing Advance Co., Ltd.) was switched to renewable sources in fiscal 2022.
  • The Casio Computer Co., Ltd. headquarters stores power by using power at night, when demand for power is relatively low, and uses a heat storage system for heating and cooling during the day, when activity is greatest.
