Avient Climate-related Scenario Analysis Summary SCOPE & TIME HORIZON AVIENT SCENARIO NET ZERO FUTURE PLEDGING PROGRESS STEADFAST POLICY CONVENTION 1.3-1.5°C 1.9-2.3°C 2.4-2.8°C TRANSITION RISK Net Zero Emissions Scenario Announced Pledges Scenario Stated Policies Scenario (IEA WEO 2021 1 scenarios) (NZE) | 1.4°C (APS) | 2.1°C (STEPS) | 2.6°C Emissions peak at 2050 and slowly decline through 2100 Emissions continue to rise beyond 2100 at slower rates Emissions continue to rise beyond 2100 at current rates BUSINESS IMPLICATIONS Increased transition risk: Business impacted by climate policies, carbon prices, market pressures and technological advancements Increased physical risk: Business impacted by direct damages and indirect discruption assocated with severe changes in climate driven weather events · Highly regulated policy environment · Moderate policy regulation · Few changes to current policy settings · Ambitious; net zero commitments achieved at most all levels · Government commitments and National Determined Contributions are achieved · Not all stated commitments are achieved · Improved air pollution in advanced and emerging market & developing economies · Rising air pollution levels especially in emerging market and developing economies · Doubling of the frequency of extreme heat events by 2050 and 120% increase in intensity & rising air pollution levels especially in emerging market and developing economies · Expectation of signifcant capital allocation for innovative product design, energy efficiency investments, and clean electrification of operations · Additional levels of R&D investment will be required to contribute to and attain announced commitments. · Continued R&D investment in current initiatives is expected · Steep increases in advanced economies' carbon prices · Considerable increases in emerging economies' carbon prices · Some change in carbon prices · Declining fuel prices · Regional variability in fuel prices, though slight net increase · Rising fuel prices 1 International Energy Agency World Energy Outlook 2021 The following summarizes Avient's climate-related risks and opportunities analyzed across multiple scenarios, in alignment with the Task Force on Climate-Related Financial Disclosures (TCFD) framework. Additional renewable energy will still be needed in Europe to offset the related grid emissions as will we also need to identify similar outlets in the Americas and Asia Pacific. · By 2030, Avient will obtain directly or contract for 60% of its electricity demand from renewable sources and achieve 100% renewable energy by 2050. · We have established a product carbon footprint team that focuses on providing product-specific carbon footprint metrics based on where and how the product is manufactured. · Our position in enabling the use of recycled materials, bio-renewable solutions, renewable energy, or energy reductions requires manufacturing in a manner and light weighting of transportation vehicles so that they contribute to more efficient value chains and accelerated lower-carbon transitions for our customers. · In 2021, we delivered $915 million in sustainable solutions sales, as defined using critieria aligned with the FTC 2012 Guide for the Use of Environmental Marketing Claims. · We are evaluating our Asia Pacific go-to-market strategy, especially in China.
