Eni is committed to protecting the planet’s natural resources in all contexts in which it operates.
For years Eni has recorded rather low consumption of fresh water, thanks to the use of sea water (over 90%) mainly for thermal cooling. Fresh water is used (approximately 119 million m3, -7.9% vs 2016) essentially in the downstream production and the production of electricity and only a small part (8%) is used in the upstream sector. As part of the circular economy, Eni invests in further improving water treatment systems, aimed at enabling industrial re-use of poor quality water. In the downstream section, consistent volumes of water are made available for industrial use (from 4.2 to 6.0 Mm3/ year for the next 4 years), thanks to the groundwater treatment plants (TAF), while in the petrochemical sector, which is responsible for over 60% of Eni’s fresh water withdrawals, the recycling/reuse rate of fresh water reached 90% in 2017. In 2017, only 5% of freshwater water withdrawals were in water stressed areas.
The conservation of natural resources, ecosystems and biodiversity is fundamental for us and in line with our policies.
Eni operates in very different geographic contexts that require specific environmental assessments to minimise the impact of its activities. To ensure a uniform approach in line with the best international technologies and practices, Eni has adopted an integrated Health, Safety and Environment Management System at all its plants and units. Sustainability and environmental performance objectives are monitored and managed on a six-monthly basis.
On 6th June, the second edition of Safety & Environment Day took place, a day dedicated to Eni's excellence and innovation in the field of safety and the environment. Safety & Environment Day has replaced the historic "Safety Day", which was established in 2012. During the event the 22 prizes were awarded among the operating realities, the people and the teams that have developed the best ideas and projects to protect the environment, and that achieve the best performances, to enhance the positive examples and stimulate the spirit of emulation.
In 2017 there was a decrease of the total water withdrawals of 3.5 % compared to 2016 (equal to about 65 Mm3), due to the decrease in sea water withdrawals (-3.5%, for a total of about 60 Mm3 less) and fresh water withdrawals (-10 Mm3), while an increase in brackish water (4 Mm3) has been observed. The reduction in fresh water withdrawals is largely attributable to the Versalis petrochemical plant in Mantua, where in 2017 withdrawals decreased by more than 6 Mm3 both due to scheduled shutdowns of some plants and the entry into service of the water recycling tank. The percentage of fresh water reuse is increasing in all sectors, with an Eni figure rising to 86% in 2017.
In the Upstream sector, the percentage of production water re-injected reached 59% in 2017, mainly thanks to the contribution of activities in Ecuador, Egypt and Congo; in the latter, good performances were due to new projects and reinjection in the Mboundi field and the reinjection of those in the Zatchi and Loango fields, following revamping activities. Efficiency is expected to increase in new development and production water reinjection projects in Nigeria, Congo and Turkmenistan.
Eni operates in several environmental contexts around the world, characterized by diverse ecological sensitivities and different regulatory regimes. The management of the BES (Biodiversity and Ecosystem Services) theme is a key component of the integrated management system for Health, Safety and the Environment (HSE), as well as Eni's operating practices.
In 2017, Eni updated the BES Policy and identified, among the international and national Eni concessions in exploitation, those that include protected areas and / or priority sites for biodiversity conservation. Eni assesses the risks both of the complexity of each project and of the value of the natural environment and the local social context.
Through the application of the Mitigation Hierarchy, Eni assigns priority to preventive mitigation measures, monitoring their effectiveness and adapting their management approach based on the observed results. In the sites currently operating in production and identified as priorities, the implementation of specific Biodiversity & Ecosystem Services Risk Assessment and Action Plan (BAP) takes place. The BAP currently underway are the following: DIME - Val d'Agri; AOE - Villano; Eni Congo - M'Boundi camp; Eni US Operating Company - Nikaitchuq field (Alaska) and Gulf of Mexico; IEOC - Egypt, Abu Madi, Nidoco, Baltim SW, Port Said North, Ashrafi, Sinai area.
In the new development projects, the verification of the correct integration of the BES themes in the (pre-) ESHIA (Studies of Special Impact, Health and Environmental) or through ad hoc integrative studies is followed. In the exploration initiatives, instead, the correct integration of the BES issues in the Environmental Context Evaluation (ECE) in the pre-bid or bid phase and in the ESHIA occurs.
