Rising Ambition Must Lift All Boats!

And planes, too! ECO is thrilled that Parties are coming around to a target of 1.5°C. But how would we all feel if we got back home and realized—oops!—we left out two huge emitters? International aviation and shipping emissions are equivalent to the carbon emissions of the UK and Germany, are not included in national targets. These emissions are expected to grow up to 270% by 2050. Leaving them out of the agreement would be letting efforts to keep temperature rise under 1.5°C just float on by.
ICAO and IMO are the right UN agencies to regulate these sectors. But, they need to step up their ambition quickly. They can, and must, tackle bunker emissions  in a way that accommodates equally both differentiation and the principles of non-discrimination under which these agencies operate.
