We have set targets for energy consumption, CO2 emissions, water consumption, waste emissions, etc., and seek to meet these targets through improvement of building management, capital investment, energy efficiency training for tenants, property managers, etc. and other initiatives.

Set Targets

The one-year period every year from April 1 to March 31 of the following year (fiscal year) is set as the target commitment period for annual targets.
The five-year period from fiscal 2020 to fiscal 2024 is set as the target commitment period for medium- to long-term targets and, in principle, medium- to long-term targets are set again every five-year period thereafter.

■　Energy Consumption and CO2 Emissions

Short-term target: To reduce intensity for the entire portfolio and individual properties by 1% every year
Medium- to long-term target: To reduce intensity for the entire portfolio and individual properties by 5% in five years

■　Water Consumption

To reduce intensity for the entire portfolio and individual properties to not exceed that of the previous fiscal year every year

■　Waste

To reduce absolute volume for the entire portfolio and individual properties to not exceed that of the previous fiscal year every year

Performance Data

■　Energy Consumption

Fiscal Year	2019	2020	Rate of change year on year
Absolute Consumption (MWh)	57,205	52,654	92.0%
Consumption Intensity (MWh/m2)	0.02710	0.02507	92.5%

(Note 1)	Performance data is based on the amount consumed in the common areas and tenant areas of office buildings managed by NUD. In addition, for co-ownership properties, the figures are adjusted according to the ownership ratio. Intensity is calculated by dividing each consumption/emission for each fiscal year by intensity denominator (Cumulative leased area (㎡) in accordance with the period of ownership of each office building).
(Note 2)	Due to the review of the data aggregation method, the data of the previous year is updated.

■　CO2 Emissions

Fiscal Year	2019	2020	Rate of change year on year
Absolute Emissions (t-CO2)	20,997	17,517	83.4%
Emissions Intensity (t-CO2/m2)	0.00995	0.00834	83.8%

(Note 1)	Performance data is based on the amount consumed in the common areas and tenant areas of office buildings managed by NUD. In addition, for co-ownership properties, the figures are adjusted according to the ownership ratio. Intensity is calculated by dividing each consumption/emission for each fiscal year by intensity denominator (Cumulative leased area (㎡) in accordance with the period of ownership of each office building).
(Note 2)	CO2 emissions are calculated using the adjusted emission factors provided in the Ministry of the Environment's "Mandatory Greenhouse Gas Accounting and Reporting System."
(Note 3)	Due to the review of the data aggregation method, the data of the previous year is updated.

■　Water Consumption

Fiscal Year	2019	2020	Rate of change year on year
Absolute Consumption (m3)	191,434	141,702	74.0%
Consumption Intensity (m3/m2)	0.09070	0.06747	74.4%

(Note 1)	Performance data is based on the amount consumed in the common areas and tenant areas of office buildings managed by NUD. In addition, for co-ownership properties, the figures are adjusted according to the ownership ratio. Intensity is calculated by dividing each consumption/emission for each fiscal year by intensity denominator (Cumulative leased area (㎡) in accordance with the period of ownership of each office building).
(Note 2)	Due to the review of the data aggregation method, the data of the previous year is updated.

Examples of Initiatives

■　Switching Lighting to LED

Switching lighting in common areas, rental units, etc. of portfolio properties to LED in view of environmental consideration and cost reduction.

■　Introduction of Water-Efficient Equipment

Introducing water-efficient equipment at portfolio properties in view of environmental consideration and cost reduction.

■　Introduction of Green Leasing

“Green lease” is an arrangement providing for the promotion of energy efficiency and environmental consideration by both the building owner and tenant sides through building lease agreements. At NUD, initiatives include switching lighting in tenants’ exclusive areas to LED with the understanding of the tenants.

■　Purchase of Green Power Certificate

The "Tradable Green Certificates System" is a scheme in which the certification issuer obtains certification a third-party certification organization and trades the environmental added value of electricity generated from natural energy in the form of a "Green Power Certificate." "Environmental added value" refers to saved energy and curbed CO2 emissions other than the "value of electricity itself" of natural energy. Concluded a contract to purchase this certificate by utilizing renewable energy in 15 office properties such as Landic Shimbashi Building. This will contribute indirectly to the widespread use of natural energy and the prevention of global warming.
