The Aircraft on the Ground CO2 Reduction (AGR) Programme Best Practice Guidance has been published by Sustainable Aviation, the Clinton Climate Initiative and Airport Operators Association. The publiaction,which can be accessed in the Key Documents section of ths website, will help to  to contribute towards CO2 emission reductions from aircraft ground operations at UK airports through collaborative action taken by airports and their stakeholders. The AGR programme has developed a menu of pragmatic and effective "action steps" for airports to deploy in concert with the wider aviation community.  This best practice document represents a first step towards the full realisation of these CO2 savings on the ground. AOA member airports will trial the guidance over a twelve month period, examining how best to implement the "action steps" identified in this document, and further developing the aviation industry’s understanding of and ability to manage CO2 emissions on the ground.
