A US judge in Montana has stopped the construction of the Keystone XL pipeline by TransCanada which was set to build a pipeline from Alberta to the US. He said the Trump administration failed to show evidence that the project would not increase greenhouse gas emissions, which was the reason why it was blocked by the Obama administration, and violated numerous federal regulations as well.
