Daikin’s Approach to PFAS

Updated: February 12, 2026

Daikin invests heavily in the research and development of PFAS to ensure that the unique properties of fluorinated materials can be safely utilized across a wide range of industries, including health, safety, comfort, security, and environmental conservation. We develop products that comply with regulatory requirements in each country.

As part of our commitment to environmentally conscious and sustainable production activities, Daikin recognizes the importance of continuous improvement in all manufacturing processes and we are dedicated to pursuing the development and practical application of innovative technologies to ensure the safe manufacture and use of PFAS products.

Daikin's Policy for PFAS

Fluoro materials, including those considered PFAS, are used in essential societal applications such as semiconductors, automobiles, telecommunications, medicine and medical devices, energy, and air conditioning/heatpumps/refrigeration. They contribute to a variety of advanced industries and play an important role in promoting global sustainability solutions such as carbon neutrality and Green Transformation (GX). Daikin will continue to comply with regulations and supply those materials that have met rigorous scientific evaluation in meeting the essential needs of society.

We strive to minimize the environmental and social impact of our products throughout their lifecycle by engaging in sustainable production practices. As a responsible manufacturer, we are committed to contributing to social advancement.

Minimizing PFAS Emissions

Daikin’s manufacturing sites around the world will continue to work closely with regulatory authorities to comply with regulations and strive to reduce environmental impact. We are investing more than $300 million to capture PFAS in our water discharges.
We have achieved our internal target of recovering 99% of the polymerization emulsifiers released from the fluoropolymer manufacturing processes in the United States and Europe.
All Daikin manufacturing facilities are now working towards a new internal target of 99.9% PFAS (*1) capture in process water discharges. Once achieved, this ambitious goal will help minimize the potential impacts of PFAS manufacturing and set a new benchmark for responsible PFAS-related manufacturing across the globe.

Continuous Improvement

Daikin is committed to continuously improving all manufacturing processes and exploring and implementing new technologies to ensure the safe manufacture of chemical products.

As part of this effort, we are transitioning our fluoropolymer manufacturing processes to more sustainable new technologies. For fluoroelastomers, we completed the planned establishment of new technologies in 2025 and began product sales in 2026, successfully achieving our goal. Additionally, for new manufacturing facilities constructed from 2023 onwards, we are introducing manufacturing methods that adopt sustainable technologies.

Development of PFAS Destruction Technologies

Daikin is also focusing on the development of advanced technologies to destroy PFAS. In particular, we are focused on establishing technologies that can be implemented at actual wastewater treatment sites, ensuring technology development with practical applications.

Through industry-industry and industry-academia collaboration, we are accelerating the speed of development, while working to establish solutions that balance practicality and efficiency among the many PFAS destruction technologies being researched.

Recycling Initiatives

Daikin is working on the collection, reuse, recycling, and destruction of fluorochemical products it manufactures, aiming to reduce the environmental impact throughout their lifecycle for circular economy.
