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 reSoundTM 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. We are positioned to capture enhanced market share over expanding and emerging needs that will also enable climate resiliency High revenue growth opportunities to meet demand for highly efficient chemical materials that will contribute to lowering customers' emissions as part of our Sustainable Solutions label High to moderate revenue growth opportunities for new chemical materials pertinent to Avient's customers' strategies (low-carbon and otherwise) and are in compliance with any existing regulations (i.e., VOC reducing materials that address vehicle air quality standards) Impact Legend Time horizon Legend Low impact S - short-term 0-5 years Moderate impact M - medium-term 5-15 years High impact L - long-term 15-30 years BUSINESS IMPLICATIONS AND STRATEGIC RESPONSES BUSINESS IMPLICATIONS AND STRATEGIC RESPONSES IMPACT DRIVER & TIME HORIZON Policy & Legal Risk M L Technology Risk S M Market Risk S M Reputation Risk L Acute & Chronic Risk L IMPACT DRIVER & TIME HORIZON Resource Efficiency Opportunity S M L Energy Source Opportunity M L Products & Services and Markets Opportunities S M L · We have embedded an energy intensity KPI (covering process and builidng efficiencies) into the incentive structure for all employees. · By 2030, Avient will enable 100% of our products manufactured for packaging applications to be recyclable or reusable to advance the circular economy, for which approximately 90% of Avient’s products met this criteria in 2020. Clean electrification of our operations and processes will represent some of our current scope 1 emissions reductions, though further evaluation is required. · Avient became a member of the RE100 initiative in 2021, committing to achieving 60% renewable energy use by 2030.
