Ryanair claims to be one of the fastest growing airlines in Europe, growing in fact somewhat faster than the increase in emissions attributed to the airline industry in general, and faster than the airline industry overall. Irrespective of how efficient its fleet is, it therefore follows that the amount of emissions produced by Ryanair is increasing as a proportion of the total produced by airlines. Seeing as all Ryanair's fleet is the same, 10% more Ryanair aeroplanes and 10% more Ryanair flights broadly speaking means 10% more crap being kicked into the environment by Ryanair. Whilst I fully agree that the airline industry is being unfairly singled out at present (especially in comparison to other polluting industries), given Ryanair's growth the airline seems to be a very legitimate target to be singled out for criticism from within the industry in general.
