In support of our wider sustainability agenda, we launched a new low carbon PTA1, PTAir, in 2016, offering our customers in the polyester value chain the opportunity to purchase a lower carbon feedstock. A feature of PTAir is its use of proprietary PX and PTA technology which supports a 29% lower global warming potential than the average European PTA production2, which has been independently assured. INEOS customers can also go further in advancing their low carbon objectives by accessing the additional benefits of PTAir Neutral.
 based on an independent cradle-to-gate Eco-profile by IFEU reviewed by ERM Certification and Verification Services (ERM CVS). The study conducted by IFEU uses Plastics Europe Methodology to compare the environmental impact of 1 Kg of BP Geel PTA manufactured with BP integrated PX (integrated production) to PTA produced in Europe as published in the Environmental Product Declaration of the PET Manufacturers in Europe February 2016. The study is in accordance to ISO 14040–44 requirements. Data for both studies are based on 2013. Mass balance approach based on the proportion of integrated PX versus total consumption.
 This figure is compared to the Global Warming Potential (100 years) per 1 kg PTA as published in the Environmental Product Declaration of the PET Manufacturers in Europe February 2016. PTA produced by bp Aromatics NV in Geel is included in the European study average and represents ~30% of the total installed production capacity in Europe in the input.
