Global tourism accounted for 8% of the world's greenhouse gas emissions from 2009 to 2013, according to a paper published in Nature Climate Change — four times more than previous estimates.
The big picture: The biggest culprits for the jump were transportation, shopping, and food. Not surprisingly, high-income countries were the main drivers of the increased carbon footprint — but, as the cost barriers of international travel come down, more and more people worldwide are able to head abroad.
Electricity, the thing we all use but don’t really notice, has unexpectedly become a hot topic under President Trump.
Why it matters: His administration is mulling bailouts for coal and nuclear power plants in a questionable attempt to strengthen the electricity grid.
