Products & Services and Markets Opportunities S M L Avient's role in producing innovative and low-emissions materials through light- weighting, creation of sustainable infrastructure, and advanced recycling technologies is instrumental in the global transition. 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. While we have a very small footprint in other rest of world countries, such as Singapore, Thailand, Vientam, Malaysia, it is difficult to receive the resources needed to make substantial decarbonization action in these countries. · Well-documented and integration of oversight of the development and performance of climate-related solutions will help to ensure product-level carbon intensity reductions.
