It has emerged from a leaked proposal that the EU Commission is admitting its Emissions Trading Scheme (ETS) would only delay aviation emissions three to six months by 2050.  ETS would only reduce the growth of airtravel by less than 3% over a 15-year period. This shows that quotas will not deliver necessary results in tackling climate change. Airlines will be making huge profits enabling them to buy as many carbon permits as they require. ETS only promotes "business as usual" with more profits to "dirty" industries.
