Carbon Footprint Infographic Downstream COMMON TERMINOLOGY Carbon Dioxide Equivalent (CO2e): A common way to measure and report greenhouse gas (GHG) emissions such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6) Emission Standards: The classification of emissions across the supply chain Scope 1: Direct emissions from sources that are owned or controlled by an organization (e.g., company-owned vehicles, process emissions, and on-site heating) Scope 2: Indirect emissions from purchased indirect sources, such as the production of electricity and steam for an organization’s use Scope 3: Indirect emissions from sources up and down the supply chain, including materials, transportation of goods, and the processing, use, and end-of-life treatment of sold products Cradle-to-Gate: Carbon impact of a product from raw materials and product manufacturing Cradle-to-Grave: Carbon impact and analysis across the entire life cycle of a product from raw materials to disposal © 2023 Avient • www.avient.com • 1.844.4AVIENT Raw Materials Supply Chain UNDERSTANDING CARBON FOOTPRINT CO2e Transportation End-of-Life Treatment Processing of Goods Use of Products Transportation Chemical Processing Cradle-to-Gate (B2B) Cradle-to-Grave (B2C) SCOPE 3 INDIRECT SCOPE 3 INDIRECT Electricity Steam Company Facilities Company-Owned Vehicles SCOPE 1 DIRECT SCOPE 2 INDIRECT Reporting CompanyUpstream

Homepage // News Center // PolyOne Launches New Black Masterbatch Colorants with Sustainable Carbon Black OnColor RC Environmental Black is made using Bolder Black®, a reclaimed version of carbon black made from scrap rubber. It creates a smaller carbon footprint than virgin carbon black because it uses 90 percent less water and 61 percent less electricity while emitting 90 percent less carbon dioxide in its manufacturing process.*   “We continue to look for ways to help our customers meet their sustainability goals by developing products that are environmentally responsible,” says Kevin Jones, general manager, PolyOne Color & Additives, North America.

FIBER + RESIN = COMPOSITE Carbon fiber is formed by bonding carbon atoms together to form a long chain. STRONG, LIGHTWEIGHT ALTERNATIVE TO METAL CARBON FIBER COMPOSITES Thomas Edison used carbon fiber as light bulb filament in the late 1800s. The first petroleum-based carbon fibers were invented in 1958 near Cleveland, Ohio by Roger Bacon.

This includes the industry-first carbon-neutral thermoplastic elastomer (TPE), reSound™ Ultra-Low Carbon Footprint TPE, launched in 2022.  

Homepage // News Center // Carbon Fiber Underbody Braces Make Corvette Driving Experience Even More Exhilarating The Glasforms business unit formulated a carbon-fiber-reinforced composite material for the C7 Corvette Z06 and non-Z06 underbody braces. The carbon fiber-reinforced composite part was 17% lighter than the stock aluminum part, and the composite held up well in GM's extensive vibration, shake and road test regimen.

Homepage // News Center // New Edgetek™ and LubriOne™ PKE Materials from Avient Replace Nylon and Acetal, Reduce Carbon Footprint The new materials also offer sustainability benefits over the product lifecycle through carbon footprint reductions compared to competitive materials - PK base resin production emits up to 61 percent less carbon dioxide (CO2) than nylon and POM.

Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio. IARC’s listing of carbon black as a Group 2B carcinogen is based on laboratory rat studies only; studies on carbon black production workers have not shown a link between carbon black exposure and cancer. Consumer exposure to carbon black is negligible.

CARBON FIBER FIBERS PROCESSES PRODUCTS Molecular Structure Chemical Name Carbon, Graphite. The precursor undergoes several processes including carbonization and oxidation which produces high tensile & modulus carbon fiber filaments. Carbon fiber can also be produced from other carbon-rich precursors such as Pitch & Rayon.
