This is a video introducing the Tokyo Cap-and-Trade Program, an emissions trading scheme implemented by the Tokyo Metropolitan Government (TMG). The Tokyo Cap-and-Trade Program is Japan's first mandatory emissions trading scheme. It was launched on 1st April 2010 as part of the Tokyo Climate Change Strategy and is currently in its first compliance period (FY2010-FY2014). The Tokyo Cap-and-Trade Program is a unique program as it regulates commercial and industrial GHG emissions at the level of large-scale buildings. Indeed, as Tokyo is a huge energy-consuming city, TMG deemed it most appropriate and efficient to target demand-side facilities consuming electricity and gas.
