Executive Summary on the Environment

NSK’s Environmental Policy

A sense of crisis is growing over the advance of global warming and climate change, depletion of resources, chemical pollution of air and water, and loss of biodiversity. All of humanity faces the challenge of learning to live sustainably while protecting the global environment.

Back in 1997, the NSK Group established the NSK Environmental Policy to reflect its commitment across all of its business operations to help protect the global environment, as stated in the NSK Mission Statement. In line with this policy, we strive to develop products and services that help reduce environmental impact, and we work to reduce the impact of our own operations and throughout our value chain. In November 2021, we revised our environmental policy in light of the increased worldwide environmental concerns of recent years and the associated expectations of companies.

The NSK Group practices global environmental management and is careful to ensure environmental compliance. We are making a difference by helping the world reduce its carbon footprint, maximize recycling, and honor the natural environment. Take, for instance, bearings that decrease energy loss. Through these kinds of advancements, NSK products are helping to reduce environmental impact around the world. The NSK Group is also committed to supporting the achievement of the Sustainable Development Goals (SDGs) by reducing the environmental impact of its business operations to zero.

* Greenhouse gas emissions (CO2 equivalent) are calculated by multiplying emissions from use of an amount of electricity, fuel, etc., by its respective global warming coefficient. In Japan, the global warming coefficients used are given in the Ministry of the Environment's and the Ministry of Economy, Trade and Industry’s Greenhouse Gas Emission Calculation and Reporting Manual. Outside Japan, the global warming coefficients used are released by electricity providers or given in the International Energy Agency’s CO2 Emissions from Fuel Combustion.

Environmental Risks and Opportunities

The international community has accelerated its efforts to build a sustainable world with the Paris Agreement, ESG Investments, and the Sustainable Development Goals (SDGs). While upholding its commitment to protection of the global environment, the NSK Group pursues continued growth by analyzing and responding to risks and opportunities associated with these developments. We identify and assess environmental risks and opportunities in each phase of the value chain, reflecting them in our management strategies and environmental action plans. We conduct this analysis of risks and opportunities on a regular basis.

Material and Energy Balance

The NSK Group works with suppliers to reduce environmental impact via green procurement and other initiatives. We also strive to reduce the environmental impact of our customers and of society as a whole by providing environmentally friendly products.
