EU pushes back against weakening of aviation emissions deal

European countries are pushing back against any weakening of the rules underpinning a landmark global agreement to cap airline emissions at 2020 levels, especially those related to the types of aviation biofuels that can be used. France, Norway, Finland, Belgium, Austria and the Netherlands have written to ICAO to say they would have to reconsider their support should the compromise be weakened. This related particularly to criteria for the sustainability of alternative fuels and the carbon credits used to offset CO2 emissions. "If some countries were to call into question certain aspects of the compromise, notably with regards to the emissions units and the sustainability of alternative fuels, the support given by France to this version of the text would be compromised," France wrote in a letter to ICAO. <br/>
