http://www.kankyo.metro.tokyo.jp/en/index.html Introduction In the year 2000, the Tokyo Metropolitan Government (TMG) replaced the Tokyo Metropolitan Pollution Prevention Ordinance with the Tokyo Metropolitan Environmental Security Ordinance, which covers countermeasures for vehicle pollution, chemical substances and climate change. The reason for the replacement was a shift in Tokyo’s environmental problems from industrial pollution mainly attributable to factories to urban and domestic pollution due to vehicle emissions and chemical substances, which may sometimes be related to climate change problems. In 2002, we started two programmes on which Tokyo’s present climate change strategy has been based: Tokyo Green Building Program for new buildings and Tokyo Carbon Reduction Reporting Program for existing large facilities. Since 2005, we have been promoting environmentally superior developments by introducing a mechanism to evaluate and disclose facilities’ efforts made in the programmes. In Tokyo’s Big Change - The 10-Year Plan developed in 2006, we set a goal of reducing citywide greenhouse gas emissions by 25% below 2000 levels by 2020 to make Tokyo a city with the least environmental impact in the world. Then in 2007, we announced the Tokyo Climate Change Strategy, which clarified our basic attitude toward tackling climate change for the next 10 years. Following a revision of the Tokyo Metropolitan Environmental Security Ordinance in 2008, we launched the Tokyo Cap-and-Trade Program for large facilities, the world’s first urban cap- and-trade scheme that covers office buildings as well, and the Carbon Reduction Reporting Program for small and medium facilities, committed to advancing our climate change strategy ever since then. We were able to overcome the power crisis brought about by the Great East Japan Earthquake in March 2011 through emergency power saving, leveraging our experience from the climate change strategy, enabling smart and continuous electricity saving and energy efficiency to be rooted in homes and businesses in Tokyo. This report is designed to introduce the framework and accomplishments of the Green Building Policy promoted by Tokyo as a huge energy consumer, focusing on the Tokyo Cap-and-Trade Program, which has achieved tangible CO2 reductions in the city since its commencement. July 2015 Bureau of Environment Tokyo Metropolitan Government As a massive energy consumer, the Tokyo Metropolitan Government has taken pioneering measures for climate change mitigation and energy saving. Fine-tuned to the characteristics of megacities dense with various types of buildings, including offices, our efforts represented by the Tokyo Cap-and-Trade Program have produced concrete results, owing to support from many businesses, homes, and NGOs in Tokyo. Key to climate change of some whole countries, such as reduction goal, we set another goal of countermeasures in future: Austria. reducing Tokyo’s energy consumption Megacities The commercial and domestic by 20% below 2000 levels by 2020 The more frequent extreme sectors constitute a large share of in March 2014, concentrating on the weather resulting from climate CO2 emissions in Tokyo, where offices energy consumption itself. change has become one of the most and other buildings are concentrated, In December 2014, we set a new serious environmental problems. while the industrial sector, including goal of reducing Tokyo’s energy The Fifth Assessment Report by the factories, accounts for a high consumption by 30% below 2000 Intergovernmental Panel on Climate proportion of CO2 emissions across levels by 2030 in order to continue Change (IPCC) says that climate Japan. and increase the energy saving efforts change is beyond question, and into 2020 and beyond. human activities are very likely to In pursuit of reducing energy be a dominating factor for the rise consumption and GHG 16% reduction achieved in in the world’s average temperature emissions FY2012 with help from people continuing since the mid-20th century.
