Eastman continuously strives to enhance the sustainability of our products and manufacturing processes. Eastman uses life cycle assessment (LCA) to analyze the potential environmental impacts of our products throughout their life cycles and the value chain—from raw material and resource extraction to manufacture, and when possible, downstream retail and distribution, consumer use, and end of life.
The beginning of the analysis of our products is looking at emissions upstream and downstream of our production. We appreciate that we can make a bigger difference when we rely on collaboration and transparency all along the value chain.
Eastman uses bilateral exchange agreements to swap commodity materials between countries, which reduces the distance product must be shipped, lowers logistical costs and reduces the potential environmental impact of those logistics. The environmental impacts of shipping are large and can be tracked using life cycle assessments (LCAs).
In 2015, Eastman’s LCA team completed a gate-to-gate life cycle assessment of delivery of products from the manufacturing site to a distribution location, focusing on the difference in impact associated with employing bilateral agreements with other companies that enable logistical savings. The study exclusively assessed the transportation stage in the life cycle and included all of the company’s bilateral agreements from 2015. The study determined that by using these bilateral agreements Eastman can save about 2,400 tons of CO2 emissions per year, approximately 4% of the total emissions of the product from cradle to gate or from raw materials extraction through point of sale. The emissions savings are equivalent to the annual energy to power 225 homes or almost 6 million miles driven by the average passenger car.
