The graph shows the performance of CO2 emissions reduction at customers’ plants and business sites through proposals of the Kurita Group. These mainly represent reduction in fuel use by maintaining or improving heat efficiency in boiler and cooling water facilities. It also represents the impact of adopting inverters for rotating equipment in water treatment facilities. In fiscal 2019, we revised the scope and method of data aggregation.
The Kurita Group Approach
The Kurita Group recognizes abnormal weather and natural disasters due to global warming and other climate change issues as a major social challenge to be addressed globally. One of the ways we are responding to climate change is taking steps to reduce our CO2 emissions by reducing our in-house per-unit energy consumption. At the same time, we are working to optimize energy use at our customers’ plants and business sites, and to promote the spread of energy-creating technologies.
Contribution to Achieving the SDGs
Targets and Achievements
The Kurita Group aims to achieve a reduction of environmental impact through its business that offsets and even exceeds the environmental impact generated by its business. To this end, we have set targets for the “amount of the reduction in environmental impact of customers - the amount of the Kurita Group’s own environmental impact.” We will continue to measure these actual values going forward values.
|Target for FY2023||Achievement in FY2020|
CO2 emissions reduction at customer*1
– CO2 emissions from our business activities*2
|10,000 t||43,000 t|
- *1 Please refer to the link below for the details of “CO2 emissions reduction at customer.”
- *2 “CO2 emissions from our business activities” includes emissions generated from ultrapure water supply business which applies to Category 13 of Scope 3 adding to the Scope 1 and 2 stipulated in GHG (Greenhouse Gas) protocol.
In order to make efforts in line with the Paris Agreement, the Kurita group has set the long-term targets aligned with the well below 2℃ indicated by SBTi*3, starting from the fiscal year ended March 31, 2020 as the baseline year, and are working to reduce Scope 1, 2 and Scope 3 emissions in addition to the above-mentioned targets.
|Scope 1 and 2 emissions reduction
(Reduction rate from FY2020)
|Scope 3 emissions reduction
(Reduction rate from FY2020)
- *3 An initiative that encourages companies to set greenhouse gas emission reduction targets in line with scientific knowledge, with the goal of limiting global average temperature rises due to climate change to well-below 2℃ compared to pre-industrial levels.
Reducing CO2 Emissions at Customers’ Plants and Business Sites
Environmental Improvement of
Environmental Improvements at CELUPA INDUSTRIAL CELULOSE E PAPEL GUAÍBA LTDA.
(Initiatives of Kurita do Brasil LTDA.)
CELUPA INDUSTRIAL CELULOSE E PAPEL GUAÍBA LTDA. manufactures various types of specialty papers for sterilization processes, food packaging and the production of coffee filters. The papermaking process requires the use of steam, so one challenge at the company is reducing the amount of fuel used for steam generation, thus reducing CO2 emission as well.
Kurita do Brasil LTDA. proposed the use of a new technology “KURITA PJ” for raising thermal conductivity by water-proofing the metal surface of the paper drying drums that are heated by steam. A layer of water is formed inside the drying drums when steam condenses on the metal surface in contact with the steam. Even when extremely thin, this water membrane greatly reduces heat conductivity, which causes more energy to be consumed in the papermaking process. Kurita do Brasil proposed a technology to eliminate this water membrane. Treating the steam with a water-proofing chemical successfully reduced the amount of heat needed, which in turn reduced the fuel consumption per ton of paper produced by 2.8%.
Voice of the Customer
Ms. Natalie Figueiredo da Silva
Application of PJ Technology has been advantageous for our process. In addition to the reduction in steam consumption, we achieved environmental gains by reducing the carbon footprint and consumption of fresh water to produce the steam.
With Kurita PJ the process works in stability and brings important gains for CELUPA.
Internal Environmental Improvement Activities
Reducing Energy Usage within the Kurita Group
Internal Promotion of
Based on the characteristics of each company and business site, the Kurita Group selects the items that are strongly correlated energy usage, such as production volume, net sales, or site area, as the denominators for a per-unit measurement, then set about 1% reduction of energy usage per unit year on year. Since fiscal 2019, we have been aggregating results for overseas Group companies as well.
Example of Reducing CO2 Emissions at Kurita do Brasil LTDA.
Kurita do Brasil LTDA. is an overseas Group company that produces Kurita Group water treatment chemicals by blending previously manufactured chemical substances. The company sells the water treatment chemicals and supplies technical services in South America. The company’s CO2 emissions are derived from electricity used in production facilities and offices and from fuel in customer support vehicles.
To reduce CO2 emissions in the fiscal year ended March 31, 2020, the company adopted LED lighting, mainly in production areas, and switched from gasoline to ethanol fuel in customer support vehicles. Many vehicles in Brazil are compatible with ethanol fuel, as the country has a long history of producing bioethanol from sugar cane. Those initiatives reduced CO2 emissions by 14% year on year.
Scope 3 Emissions Data Account and Initiatives
From the fiscal year ended March 31, 2020, the Kurita Group has ascertained data on Scope 3 emissions as part of efforts to address climate change in line with international standards. We found that Scope 3 emissions account for 98.9% of the Kurita Group’s combined emissions in the Scope 1-3 categories, with “use of sold products” such as pumps and motors generating a high proportion of Scope 3 emissions.
Using this data, we will set medium- and long-term targets for reducing greenhouse gas emissions in line with the Recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and develop measures to achieve those targets. In addition, we will increase the Group’s competitiveness by switching to solutions with a smaller carbon footprint.

The Kurita Group accelerates the actions on climate change based on TCFD Recommendations
The Kurita Group views climate change as an urgent issue that needs to be addressed globally, and continuously reduce greenhouse gases generated by our business activities and contribute to reducing greenhouse gas emissions for our customers through our business.
In order to realize the Kurita Group’s sustainable growth going forward, we analyzed the risks and opportunities of climate change and its impact on our business strategies at E&S (Environmental and Social) Committee, and set medium to long-term targets and measures for the reduction of greenhouse gas emissions based on the TCFD Recommendations.
In addition, we established a system which the Board of Directors oversees the actions on climate change issues. Please refer to “The Kurita Group’s Initiatives Addressing Climate Change" in detail.

Kurita Wins Energy Conservation Prize for Kurita Dropwise Condensation Technology
Kurita Water Industries was awarded the Agency of Natural Resources and Energy Director-General’s Award in the Product and Business Model category of the 2019 Energy Conservation Grand Prize, organized by The Energy Conservation Center, Japan (backed by the Ministry of Economy, Trade and Industry). The prize was awarded for our dropwise condensation technology, which improves heat transfer efficiency.
Condensation typically causes a layer of water to form on metal surfaces at the steam end of heat exchangers that use steam generated by boilers. While extremely thin, the layer of water drastically reduces heat transfer efficiency, resulting in higher energy consumption and lower productivity due to the larger volume of steam that needs to be used. Our dropwise condensation technology adds water repellent properties to metal surfaces in heat exchangers, eliminating the layer of water and improving heat transfer efficiency. This in turn saves energy thanks to a reduced amount of steam required, boosting productivity. Moreover, since the effect is produced by simply adding a water treatment chemical with water-repellent properties to the steam line immediately before the heat exchanger, the technology can be introduced while production facilities are operating.
