Kemira continues to work to further improve the safety performance to reach its mid-term TRIF target of 1.5 by the end of 2025 PEOPLE Kemira's target is to reach the top 10% cross industry benchmark for Diversity & Inclusion by the end of 2025. In order to promote a diverse and inclusive work environment, during Q1 2023 we continued the D&l program and related activities, e.g. planning D&I awareness training and communications, and actively developing the Women's Network and KemPride employee networks. CIRCULARITY Kemira continued to make progress in its biobased strategy and Kemira's new Growth Accelerator was fully operational during Q1 2023. Regarding waste, in Q1 2023, a waste management questionnaire was developed and assigned to all manufacturing sites in order to collect information centrally on waste reduction targets, opportunities and projects. The collected data will be analyzed in Q2 2023. WATER In Q1 2023, a water stewardship questionnaire was developed and assigned to all manufacturing sites in order to collect centrally information e.g. on water-related risks, water recycling projects and opportunities. Analysis of the collected data and update of Kemira's water risk assessment based on the data will take place in Q2 2023. Kemira also participated in the UN Water Conference in New York in March and organized an official side event discussing long-term scenarios for water management CLIMATE In Q1 2023, Kemira launched a Climate Action Program dedicated to identifying opportunities for emissions reduction throughout our value chain. These projects will be aligned with our Science Based Targets Initiative (SBTi) climate target that will be submitted for approval in Q1 2024. A supplier engagement program was implemented to collect product carbon footprint (PCF) data for raw materials to refine our Scope 3 emission inventory and to support the development of our Scope 3 SBTi target. Kemira also expanded its climate risk assessment work that began in 2022 to include 10 additional manufacturing sites and additional functions to further deepen our understanding of physical and transition risks and opportunities.
