Prevention of Global Warming
The NTN Group strives to reduce CO2 emissions generated during production and transportation.
Reduction of CO2 Emissions
Efforts in the NTN Group in Japan
CO2 emissions target achieved
For the fiscal year ended March 31, 2016, our CO2
emissions were 275,000 tons/year, exceeding our
emissions reduction target by 5,000 tons. As for our target
of reducing our emissions intensity by 23.0% (to 0.67 ton–
CO2/million yen) relative to that of the fiscal year ended
March 31, 1998, we couldn’t achieve our target; however,
we succeeded in reducing our emissions intensity (from
0.70 ton–CO2/million yen of the previous fiscal year to 0.69
ton–CO2/million yen), which represented a 21.2% reduction
relative to that for the fiscal year ended March 31, 1998,
due to a decrease in our production scale.
For the fiscal year ending March 31, 2017, we set
targets of CO2 emissions of 273,000 tons/year and CO2
emissions intensity reduction of 21.1% as compared with
that of the fiscal year ended March 31, 1998, (0.69 tons–
CO2 / million yen).

Conversion to a High-Frequency Induction Furnace
In December 2015, NTN CASTING CORP. introduced a
high-frequency induction furnace. By switching to induction
furnace from cupola furnace using conventional coal coke,
we were able to reduce our CO2 emissions by almost half.
Moreover, we succeeded in reducing both energy
consumption and the quantity of dust generated.
In addition, we achieved a higher level of safety because
the new induction furnace no longer requires that material
be bailed out from the furnace.

Two business sites of the NTN Group are awarded commendations as “Excellent Energy
Management Company.”

NTN FUKUROI CORP. and NTN Advanced Materials
Corp. were commended by the chairman of the Chubu
Electricity Use Rationalization Committee as “Excellent
Energy Management Company.”
The Chubu Electricity Use Rationalization
Committee raises awareness about electricity and
engages in activities to promote electricity utilization.
Every year, it commends individuals, companies, and
groups who promote rationalization and management of energy use.
NTN FUKUROI CORP. was a recipient of a
commendation because it engaged in energy-efficiency
initiatives covering about 40 items, including adopting
inverters for machinery coolant pumps and grinder
coolant pumps and adjusting the operating schedules
of facilities with the cooperation of all divisions. In
addition, NTN Advanced Materials Corp. was evaluated
for its various energy-efficiency initiatives, which included reducing the load on its air compressors and
decreasing overall energy consumption by 9%
compared with the level of the preceding fiscal year.

Reducing CO2 emissions in logistics
For the fiscal year ended March 31, 2016, we achieved our
target for CO2 emissions reduction attributable to logistics
by emitting only 12,800 tons year (exceeding our reduction
target by 400 tons). Moreover, we reduced our logisticsrelated CO2 emissions intensity to 0.0345 tons- CO2/million
yen from 0.0349 tons-CO2/million yen, thus meeting our
target. As for the fiscal year ending March 31, 2017, we will
make efforts to achieve our target of CO2 emissions set to
12,800 tons/year and of the emissions intensity to 0.0345
ton–CO2/million yen.
Extending Third-Party Verification to include
Scope 3 emissions
Continuing the achievement set the preceding fiscal year,
we received third-party verification of the “CO2 emissions
attributable to in-company practices (Scopes 1 and 2).” We
also received third-party verification by SGS Japan Inc.
regarding the “CO2 emitted throughout the supply chain by
practices outside the company (Scope 3).”
In the future, we will expand the verification range of
Scope 3 and will take steps to reduce CO2 emissions
throughout our supply chain.

For the fiscal year ended March 31, 2016, our CO2
emissions totaled 330,000 tons/year, which satisfied our
target (exceeding our reduction target by 7,000 tons).
As for our target of reducing our emissions intensity by
13.0% (to 1.067 ton–CO2/million yen) relative to that of
the fiscal year ended March 31, 2007, we couldn’t
achieve our target; however, we did succeed in reducing
our emissions intensity (from 1.08 ton–CO2/million yen of
the previous fiscal year to 1.072 ton–CO2/million yen),
which represented a 12.8% reduction relative to that for
the fiscal year ended March 31, 2007. For the fiscal year
ending March 31, 2017, we set targets of CO 2
emissions of 346,000 tons/year and CO2 emissions
intensity reduction of 14% as compared with that of the
fiscal year ended March 31, 2007, (1.06 tons – CO2/
million yen).
Introduction of Solar Power Generation in Shanghai
Shanghai NTN Corp. (Shanghai NTN) installed about
30,000 photovoltaic panels (representing an area of about
90,000 square meters) on the roofs of all six plants and
began generating electricity from January 2016. This
system is expected to generate 7 million kWh annually at
a rated output of 5,200 kW, which will be devoted to
about 12% of the electricity consumption of Shanghai
NTN in future.
Moreover, by reducing CO2 emissions
by 7,000 tons
annually, this initiative will help to take
measures to reduce
the summer heat.

One business site in Germany and two in France
obtained ISO 50001* registration
Since 2013, NTN Kugellagerfabrik (Deutschland) G.m.b.H.
(DMF) in Germany has been preparing for the introduction
of the ISO 50001 standard. Under the leadership of its
management, it has pushed forward with company-wide
energy-efficiency initiatives and obtained a detailed understanding of energy management with respect to individual
processes. The company thus improved its energy
efficiency and reduced its costs, and as a result it was
able to obtain certification
of registration in December 2015. At the same
time, NTN-SNR ROULEMENTS (NTN-SNR) and
NTN TRANSMISSIONS
EUROPE (NTE), both in
France, obtained the
Members of the DMF Energy Management
same certification.
Committee and ISO certificate
* ISO 50001 was published by the International Organization for Standardization in June 2011
as the international standard for energy management systems. It is intended to encourage
companies to manage their energy consumption and implement continuous improvements.
