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 CLIMATE-RELATED SCENARIOS ANALYZED Global operations through 2050 PARAMETERS & ASSUMPTIONS EXCEED 2.5°C EXCEED 2.0°C RETURN BELOW 1.5°C IMPACT DRIVER & TIME HORIZON NET ZERO FUTURE PLEDGING PROGRESS STEADFAST POLICY Policy & Legal Risk M L Carbon pricing exposure in USA, China, Germany and Spain Fines and/or compliance measures: · Clean electrification of operations; · Emissions intensive equipment phase-out; · Circular economic and materials efficiency strategies; · Net-zero carbon building standards; · Mandatory energy management systems and audits Carbon pricing exposure in USA, China, Germany, Spain, and Saudi Arabia Increased fines and compliance measures related to: · Phase-outs aligned with Nationaly Determined Contributions (NDC); · Renewable energy sourcing; · Material efficiency standards (minimum recycled content for packaging, and enhanced vechicle air quality) Some regional carbon pricing exposure in China, Germany and Spain Technology Risk S M Capital expenditures to subsitute emissions intensive technologies Declining price point competitiveness caused by decarbonization pass through costs R&D costs to transition to design and deploy lower-emissions technologies Slower substitution of materials with lower- emission options Market Risk S M Declining redundant supply and sourcing more sustainably causes raw material costs to rise Customers demand to lower their scope 3 emissions from purchased goods and services across all markets Increasing competition from existing and unforeseen polymer and non-polymer- based products that reduce further impact on climate Customer behaviors from advanced economies demand lower carbon products Rising degree of uncertainty in raw material prices Slow customer behavior changes in some advanced economies High degree of uncertainty in energy market signals Reputation Risk L Chemical sector or certain petrochemical materials (i.e., plastics) stigmatized Rising expectations for rapid innovation and displacement of older, heavily carbon- intensive designs and manufacturing processes NDC countries expected to innovate and seek rapid minimization of customers' scope 3 emissions Increased concern from stakeholders for not addressing climate change globally or for the chemicals sector Acute & Chronic Risk L Possible direct damage to fixed assets and logistics disruptions in both our value chain and operations More frequent and intense weather events and changing preciptation patterns are likely to damage manufaturing faciliites, disrupt logistics and sourcing activities, and negatively affect employee health and communities where we operate More frequent and intense weather events and changing preciptation patterns are likely to affect the performance of grids and thermal plants while pushing up demand for cooling, damage fixed assets, disrupt logistics and sourcing activities, and negatively affect employee health and communities where we operate IMPACT DRIVER & TIME HORIZON NET ZERO FUTURE PLEDGING PROGRESS STEADFAST POLICY Resource Efficiency Opportunity S M L More efficient production and distribution processes, reduced natural resource usage, continued use of recycling, and inclusion of recycled materials in our products such as reSound TM R, ColorMatrix™ Capture™ Oxygen Scavenger, among others will contribute to increasing product revenues and reduced operating costs Resource efficiency efforts supported by capital allocation in NDC countries is more likely and may accelerate a path toward maximizing ROI and reducing operating costs Less regulatory and pressure to incentivize may cause gains from efforts to lag Energy Source Opportunity M L Use of greater external financing options, such as operating lease arrangements or energy performance shared savings contracts, to source lower emission-energy and new technologies, such as carbon capture, utilization & storage (CCUS), in our operations may reduce operating costs and maximize returns on investment Use of lower emission-sources of energy in operations will lower operating costs and contribute toward reductions of our scope 1 and 2 emissions and product carbon intensities Use of renewable energy, increased efficiency, and electrification initiatives will lower operating costs and contribute toward reductions of our scope 1 and 2 emissions and product carbon intensities.
