The Keystone Pipeline system is an oil pipeline in Canada and the United States, beginning operations in 2010.
The fourth phase, referred to as Keystone XL, attracted opposition from environmentalists and was eventually denied a permit by the Obama administration in 2015. Under Trump, a permit was granted again, though construction has not yet started.
In May 2020, Biden claimed that if elected, he will cancel the permit for the Keystone XL pipeline.
If Biden is elected president in the 2020 election and takes office, will the Keystone Pipeline system be extended by at least 100 km between his inauguration and the end of 2024?
Only the length of pipeline built on US territory will count for this question.
