Denmark's expertise in efficiency and sustainability provides valuable insights while China's strides in electric vehicles highlight the significance of investing in greener infrastructure, said Leif Nielsen, director at the Confederation of Danish Industry and Danish Food and Drink Federation, in a recent interview with CGTN. He said it is very important for China and Denmark to learn from each other in achieving the goal of carbon neutrality. "I don't think any nation around the world has the full solution for the net zero yet, so we have to learn from each other," he added.
