Reduction Greenhouse Gas Emissions

To achieve the total greenhouse gas emission reduction requirements under the Tokyo Metropolitan Government's Ordinance on Environment for Protection of Resident Health and Safety, MHR has established the following reduction target.

Reduction target 5.4% reduction
by fiscal 2014
16.2% reduction
by fiscal 2019
(Note 1)
Figures are energy consumption expressed as CO2 emission volume indicating the rate of reduction from the standard emission volume, which is the average per property of any consecutive three years between fiscal 2002 and 2007.
(Note 2)
This indicates the calculated amount for all office properties excluding ARK Hills South Tower as of April 1, 2016. This is subject to change in line with the reviewing of target properties and effluent standards.

For details on Tokyo Metropolitan Government's "obligations to reduce total emissions and the cap-and-trade program" for large-scale facilities submitted by each business facility, please refer to the website of Tokyo Metropolitan Government, Bureau of Environment (Japanese).

Global-Warming Gas Emissions Based on Ordinance on Environmental
Protection by the Tokyo Metropolitan Government

(Note 1)
Business facilities imposed with obligations to reduce global-warming gas emissions in the Ordinance on Environmental Protection by the Tokyo Metropolitan Government. At MHR, all office properties excluding ARK Hills South Tower are applicable.
(Note 2)
Reduction obligation line: Maximum emission amount to meet obligations to reduce global-warming gas. It is calculated using the following formula: Reduction obligation line = (Total of standard emissions during reduction obligation period - Total of reduction obligation amount during reduction obligation period) / 5 years. (Please refer to the website of Tokyo Metropolitan Government, Bureau of Environment for details on the system)
(Note 3)
The global-warming gas emissions of properties which MHR owns as of April 1, 2016 are aggregated retroactively from past fiscal years. In addition, the global-warming gas emissions are calculated by multiplying the ratio MHR should bear with global-warming gas emissions per business facility imposed with reduction obligation, which has been reported in relation to the ordinance.
