The main objective of the project 'EVITA – Environmental Performance Indicators for the Total Road Infrastructure Assets' is to develop and integrate new and existing Environmental Key Performance Indicators (E-KPIs) in the asset management process, taking into account the expectations of different stakeholders (users, operators, neighbours, etc.). The project has been structured in four phases : 1. An extensive inventory of the so-called road stakeholders and of their expectations ; 2. An inventory of the existing E-KPIs ; 3. Some recommendations of different new E-KPIs for the environmental areas 'noise' ; 'air and water' and 'natural resources and greenhouse gas (GHG)' ; 4. Some recommendations for the implementation and the use of E-KPIs. The paper mainly reports on the three first phases of the project, being said that the third phase was still on going at the time this paper was written. A first list and definition of road stakeholders is proposed, largely based on recent PIARC and COST documents. These stakeholders are spread in categories and sub-categories when this classification proves to be helpful to correctly understand and identify their expectations. Then, the expectations from each stakeholder are listed, and their relative importance is evaluated. The need for environmental related E-KPIs is derived from this analysis inventory. On basis, the inventory of existing indicators started from previous works, such as the one done in the COST 354 action. Beyond this work, a number of sources were considered in the inventory. Performances of these existing KPIs were assessed as far as the available information made it possible. This work opens the road for the development of missing E-KPIs, dealing with: 1) Noise produced by road network management ; 2) Air and Water pollution due to road network management and 3) Natural resources - including energy - consumption. The implementation of them in Pavement and Asset Management Systems is starting and will be reported in future papers.
