Tokyo Cap-and-Trade Program

Climate change from global warming is a serious environmental issue throughout the world. In order to mitigate the risks of climate change, in fiscal 2010, the Tokyo Metropolitan Government (TMG), as an initiative to quickly and significantly reduce carbon dioxide emissions, launched the Tokyo Cap-and-Trade Program, which makes it mandatory for large-scale facilities in Tokyo to reduce their CO2 emissions.

A feature of Tokyo is that the amount of energy consumed by office buildings and other commercial facilities account for a large 40 percent of total energy consumption. Because reduction of energy use in this sector is extremely important, an urban cap-and-trade scheme was introduced to cover the commercial sector in addition to the factories and other facilities of the industrial sector. This program is not only the first cap-and-trade scheme in Japan, but also the world’s first urban cap-and-trade scheme.

Other than reducing emissions through their own efforts, facilities falling under this program can achieve their reduction targets by procuring the excess emission reductions of other facilities through emissions trading. This system allows businesses to advance initiatives in an economic and rational way.

Overview

(Tokyo Metropolitan Environmental Security Ordinance amended June 2008, enforced April 2010)

Covered facilities

  • Facilities that consume energy more than 1,500kL (crude oil equivalent) a year

Compliance period

  • 1st period: FY2010-FY2014 (fulfillment deadline: end of Sept. 2016)
  • 2nd period: FY2015-FY2019 (fulfillment deadline: end of Sept. 2021)

Base-year emissions

  • Average emissions of 3 consecutive years from FY2002-FY2007

Compliance factor

  • 1st period:Office buildings, etc. 8%, factories, etc. 6%
  • 2nd period: Office buildings, etc. 17%, factories, etc. 15%

Organization for promotion

  • Appointment of general manager and technological manager is mandatory

Non-compliance measures

  • If the target is not achieved, the facility will be ordered to make a reduction by amount of reduction shortfall multiplied by 1.3 ⇒Facilities failing to carry out the order will be publicly named, subject to penalties, etc.
