EUROCONTROL Specification for Collaborative Environmental Management (CEM)
This EUROCONTROL Specification for Collaborative Environmental Management (CEM) formalises collaboration amongst the core operational stakeholders at and around airports. The objective is to minimise the environmental impact of their combined operations, by setting out generic, high level requirements and recommended practices necessary to either establish CEM working arrangements or, flexibly adapt existing ones in a pragmatic protocol to suit local needs and capabilities.
CEM benefits and supports core operational stakeholders’ common awareness and understanding of the interdependencies and constraints facing each other’s business. This in turn can facilitate the development of shared environmental solutions, on which they can then collaborate in joint planning and implementation. CEM may thus be used to facilitate enhanced relationships; for example, ANSPs assisting airports with capacity and airports and ANSPs assisting airlines with fuel savings, thus contributing to high performing airport operations.
This Specification may also be used to facilitate compliance with the requirements of:
- Regulation (EU) No 598/2014 of 16 April 2014 on the establishment of rules and procedures with regard to the introduction of noise-related operating restrictions at Union Airports within a Balanced Approach and repealing Directive 2002/30/EC;
- Directive 2002/49/EC of 25th June 2002 relating to the assessment and management of environmental noise; and
- Directive 2008/50/EC  of 21st May 2008 on ambient air quality and cleaner air for Europe.
In addition, it can support the Essential Requirements of Regulation (EC) No 552/2004 as amended by Regulation (EC) No 1070/2009, in particular the ‘sustainability and effectiveness of air navigation services’ and the ‘need to minimise environmental impact in accordance with Community legislation’.
Furthermore, the CEM protocol has been developed by EUROCONTROL in response to Implementation Objective ENV02, included in the Single European Sky Air Traffic Management (ATM) Research (SESAR) Master Plan Level 3 Implementation Plan and it is recognised as an enabler for minimising the environmental impact of ATM systems at airports thus contributing to high performing airport operations.
The CEM protocol has been developed in collaboration with stakeholders drawn from airport operators, aircraft operators, air navigation service providers (ANSPs), trade associations, regulators, business aviation, academia and interested parties.
