Does it? It sounds dramatic:

"At 911 million tonnes, the total emissions from aviation are 50 per cent higher the 604 million tonnes reported to the United Nations for that year."

But the article suggests that all the model does is fill in the blanks for countries that didn't report to the UN (China being the largest emitter in this category). Technically true that it is 50% higher than reported, but not 50% higher than expected
