Volkswagen has reached an agreement to settle claims arising from the emissions scandal that has plagued the company since its discovery two years ago. The company has agreed to set up a $10 billion funding pool to buy back or terminate leases of diesel vehicles sold in the United States. Volkswagen had used software to cheat on emissions tests in labs for its turbocharged direct injection diesel engines. The vehicles emitted up to 40 times more nitrogen oxides in real-world driving than the company registered in lab tests.
