Driving Sustainable Economies

Sustainability performance in Q3 2023 8 DECENT WORK AND ECONOMIC GROWTH SAFETY 2/2 TRIF* in January-September 2023 improved to 2.4 (1-9/2022: 2.9). Q3 2023 TRIF was 1.7, the best quarterly performance in 2023. Kemira continues its systematic work to improve 2023 safety performance toward the 2023 TRIF target of 1.9. 8 DECENT WORK AND ECONOMIC GROWTH M RESPONSIBLE CONSUMPTION AND PRODUCTION GO CLEAN WATER 6 AND SANITATION 13 CLIMATE ACTION PEOPLE Kemira's target is to reach the top 10% cross industry benchmark for Diversity & Inclusion by the end of 2025. In May 2023, the Inclusion index improved 1 point from Oct 2022. In Q3 2023, we completed Diversity, Equity, and inclusion (DEI) training for people managers reaching 50% of all people managers. We also held DEI workshops in 12 manufacturing sites for employees, which will continue in Q4 2023 and in 2024. Kemira's employee resource groups also continued to be active, and a new mentoring program "WeMentor" was designed in the Women's Network and will be piloted during the coming months. CIRCULARITY Disposed production waste intensity** in H1 2023 was 4.3 (metric tons of waste per thousand metric tons of production; 4.4 in 2022) indicating progress towards the 2030 target of 3.9 (15% reduction from the 2019 baseline of 4.6). In addition, Kemira continued to progress its renewable solutions strategy. During Q3 2023, Kemira was particularly successful in rolling out its biomass-balanced polymer offering in the EMEA region. WATER Kemira's goal to continuously decrease freshwater use intensity was supported by a decrease in freshwater use intensity (m3/metric tons of production) to 1.1 in H1 2023 (2022: 1.2). This was due to the lower share of water-intensive products and process efficiency improvements across the company. During Q3 2023, Kemira also submitted its response to the CDP Water Security questionnaire with results expected in January 2024. CLIMATE The Q3 2023 data for Kemira's Scope 1 and Scope 2*** emissions will be available on Kemira's website kemira.com/investors in November. Kemira's Scope 1 and 2 emissions in H1 2023 were in line with Kemira's SBTi commitment. Scope 1 and 2 emissions are expected to decrease in 2023 due to decarbonization efforts in the energy supplied to Kemira's sites, and implementation of energy efficiency programs to reduce consumption. In addition, Kemira has improved its CO2e emissions intensity (t CO2e/t product) following changes in product mix. Kemira also submitted its response to the CDP Climate Change questionnaire during Q3 2023 with results expected in January 2024. *TRIF = total recordable injury frequency per million hours, Kemira + contractors Kemira OCTOBER 24, 2023 INVESTOR PRESENTATION **kilograms of disposed production waste per metric tonnes of production) ***Scope 1: Direct greenhouse gas emissions from Kemira's manufacturing sites, e.g. generation of energy and emissions from manufacturing processes Scope 2: Indirect greenhouse gas emissions from external generation and purchase of electricity, heating, cooling and steam 29
