Worldwide Fuel Specifications are Evolving USA <10ppm (2017) Brazil <50ppm (2014) Europe <10ppm (2009) South Africa <10ppm (2017) Russia <10ppm (2016) China <10ppm (2018) India <10ppm (2020) Thailand <50ppm (2012) Australia <10ppm (2012) Japan <10ppm (2007) Countries around the world are adopting low-sulfur diesel specifications that emulate Euro-V Copyright 2016 DuPont. All rights reserved. 6
Worldwide Fuel Specifications are Evolving Three key issues: satisfy global demand meet regional specifications maximize return on investment Refiners must ensure that the fuel meets local market specifications plus any specifications for pipelines and at the pump. Increasingly stringent legislation means that diesel sulfur levels will continue to fall. Copyright 2016 DuPont. All rights reserved. 7
