We are determined to reduce the use of water in all our activities.
In line with our policies, we conserve natural resources, ecosystems and biodiversity.
Eni operates in very different geographical contexts that require extremely specific assessments of their environmental aspects. Our goal is to minimise the impact of our operations on the environment. To ensure a uniform approach in keeping with the best international technologies and practices, Eni adopts a Health, Safety and Integrated Environment Management System in all its plants and production units. This system enables us to monitor and manage sustainability and environmental performance objectives on a half-yearly basis. In this context, on 6 June 2018 the second edition of the Safety & Environment Day was held to highlight Eni's excellence and innovation in the field of safety and the environment – as of 2017 this event has replaced the historic "Safety Day" first held in 2012. To spotlight positive examples and stimulate emulation among our personnel, 22 prizes were awarded during the day to the people who developed the best projects for safeguarding the ecosystem.
2017 saw a decrease in total water withdrawals of 3.5% compared to 2016 (equal to about 65 Mm3) thanks to a reduction in seawater withdrawals (-3.5%, for a total of about 60 Mm3 less) and freshwater withdrawals (-10 Mm3), while an increase in salt water withdrawals (4 Mm3) was seen. The reduction in freshwater withdrawals is largely attributable to the Versalis petrochemical plant in Mantua, where withdrawals were reduced in 2017 by more than 6 Mm3 due to scheduled shut-downs of certain plants and the water recycling tank which became fully operational. The percentage of freshwater reuse is increasing in all sectors: Eni improved its performance to 86% in 2017. In the Upstream sector, the percentage of production water reused reached 59% in 2017, mainly through the contribution of activities in Ecuador, Egypt and Congo. In Congo, good performances were achieved through new projects, re-injection in the Mboundi field and the resumption in July of those in the Zatchi and Loango fields following revamping activities. In the near future, increased efficiency is expected in Nigeria, Congo and Turkmenistan, both in new development projects and re-injection of production water.
