President Trump signed a presidential permit on Friday to authorize construction of the Keystone XL pipeline across the border between Canada and the U.S. 2 years after he initially approved the project, reports the AP.
Details: The permit allows TransCanada Corporation to begin construction on the pipeline at the Montana border to import oil between the 2 countries. A federal district court judge in Montana blocked the construction of the pipeline in November 2017, and ordered an environmental review according to the Washington Post.
A new paper in the journal Nature Communications has good news if you're in a "glass half full" kind of mood, concluding that China's carbon emissions are likely to peak well before 2030 if several things break right.
Why it matters: China has a lot to say about the planet's future. It's by far the world's largest CO2 emitter and over a fourth of the world's total.
