NGK Group Environmental Vision

To help realize the Sustainable Development Goals (SDGs) adopted by the United Nations, the NGK Group seeks to provide new value to society with our unique technology, thus contributing to the realization of a sustainable world and winning positive expectations and trust among society. The NGK Group Vision (announced in April 2021) outlines the kind of entity NGK strives to become by 2050 and stresses ESG management as a key reform towards realization. To this end, based on the NGK Group Vision and towards responding to society’s expectations and trust, in April 2021 we formulated the NGK Group Environmental Vision.

NGK Group Environmental Vision

The NGK Group will contribute to the realization of society’s direction toward “carbon neutrality,” “a recycling-oriented society,” and “harmony with nature” through its business activities.

Toward carbon neutrality

We will develop and provide products and services that contribute to the realization of a carbon-neutral society and apply them to our own business activities in order to achieve our goal of net zero CO2 emissions by 2050.

Toward a recycling-oriented society

We will contribute to the realization of a recycling-oriented society by reducing our natural resource consumption and developing and providing resource-efficient products.

Toward harmony with nature

We will minimize our environmental impact on ecosystems and raise stakeholder awareness through educational activities in order to achieve harmony with nature.

Carbon Neutrality Strategic Roadmap

The NGK Group has drawn up its Carbon Neutrality Strategic Roadmap as a working guide to realizing the goals of the NGK Group Environmental Vision.
We have established a Group-wide target of net zero CO2 emissions by 2050, with milestone targets along the way of 550,000*1 tons by 2025 (a reduction of 25% compared with the fiscal 2013 base year) and 370,000 tons by fiscal 2030 (a reduction of 50% compared with the fiscal 2013 base year). And to help society as a whole become carbon neutral, we are working to develop and provide the use of relevant products and services. In the future, we will consider advancing our efforts to achieve net zero by promoting the development of hydrogen/CCU/CCS*2-related technologies.

In order to realize our Environmental Vision, we have adopted the following four strategies.

Strategy 1: Development and provision of carbon neutrality (CN)-related products/services

In addition to pursuing our existing carbon neutrality (CN)-related products, we will also work to develop and commercialize new products as well as offer society NAS battery-driven renewable energy supply business and other relevant services.

Strategy 2: Top-down enhancement of energy-saving

We will work to further enhance our existing energy-saving activities, as well as introduce high efficiency equipment and facilities and more energy-efficient operations.

Strategy 3: Promotion of technical innovation

Although the ceramic calcining process requires fuel which is responsible for CO2 emissions, we will work to switch over to hydrogen, ammonia and other fuels that will allow us to become fossil fuel-free.

Strategy 4: Expanded use of renewable energy

In addition to promoting various renewable energy procurement strategies both within Japan and overseas, we will install photovoltaic power generation systems at manufacturing sites within the NGK Group, and use them in conjunction with NAS batteries and zinc rechargeable batteries, to achieve demand control. We will use this as a model case in NGK Group’s renewable energy business, and work towards the goal of enabling all energy demand within the NGK Group to be met through renewable energy.

*1: Emissions are a revision of the calculation standard. Specifically, the power emission factor (coefficient for converting power consumption into CO2) will be changed from the conventional fixed value to the actual value of the power company every year. This will reflect the renewable energy utilization rate.

*2: Abbreviation for Carbon dioxide Capture and Utilization and Carbon dioxide Capture and Storage, which means CO2 capture storage and utilization technology.
