Chemical Substances Contained in Products System (1) Green Procurement
We do our part to further green procurement, in this way helping to establish a recycling
society. We do this by expanding markets for green products, promoting the developmentof environmentally sensitive products, and raising awareness among designers anddevelopers. Green procurement prioritizes the purchase of materials with low
environmental impact. We have established green-procurement requirements for partsand materials and a green certification program for suppliers who meet theserequirements. Since 2005, we have maintained a green procurement rate of 100%. In
2018, we continue to make 100% of our purchases from green certified suppliers.

 Restrictions on the Purchase of Substances
Prohibited from Use in Products
In addition to green procurement, we provided a list of environmental substances
restricted by Tianma Japan. These restrictions also include chemical substances
prohibited by specific customers and other individually designated chemical
substances. Copies of these restrictions are distributed to suppliers of parts andmaterials under the title Common Specification of Green Procurement. We ask
suppliers to assess the chemical substances found in parts and materials delivered tous, based on design diagrams and the Common Specification of Green Procurement.
The data collected in this way is registered into an internal database and shared foruse in selecting parts and materials at the design stage, as well as for productassessment. Procurement restrictions also apply to chemical substances occurring inshipping and packaging materials, for which similar surveying, data registration, andmaterials selection are conducted.

Chemical Substances Contained in Products System (2) Our products are RoHS compliant
The European Union (EU) issued a RoHS Directive,*1 taking effect from July 1, 2006, that
restricts the use of certain hazardous substances. As a result, electrical and electronicequipment containing any of the six target substances (lead, mercury, cadmium, hexavalentchromium, PBB*2 and PBDE*3) is restricted from the EU market.
Out of concern for the environment, Tianma Japan began reducing the use of hazardous
substances in our LCD modules prior to the RoHS directive. We have eliminated the six
substances targeted in the RoHS directives as well as other substances we have identified
as potentially hazardous, so that our products are now RoHS compliant.
The RoHS Directive underwent major revisions in July 2011. The updated RoHS Directive(RoHS II) went into effect in January 2013.
The addition of restrictions on four phthalates*4 went into effect on July 22, 2019.*5 We
have completed compliance with RoHSII including phthalate ester regulation.

*1 RoHS: The Restriction Of The Use Of Certain Hazardous Substances
In Electrical And Electronic Equipment*2 PBB: Poly brominated biphenyl*3 PBDE: Poly brominated diphenyl ether*4 Four phthalates
DEHP: Bis（2-ethylhexyl）phthalate
DBP: Dibutyl phthalate
BBP: Butyl benzyl phthalate
DIBP: Diisobutyl phthalate*5 The restriction shall not apply to monitoring and control instruments placed on the market
before 22 July 2021.

Chemical Substances Contained in Products System (3) Compliance with chemical substances restriction(REACH regulations)
In place from June 1, 2007, the EU REACH*1 regulations require the registration,
evaluation, and authorization of all chemical substances entering the EU, based on factors
such as volumes imported or produced.
For molded products containing substances of very high concern (SVHC*2) and SVHC
candidates in concentrations of 0.1% or more, a system must be in place throughout the
supply chain to communicate information such as substance names, volumes included, andinformation enabling safe use.
To comply with REACH regulations, we are currently developing a management systemthat incorporates BOM*3 management of the parts and materials used in products, surveysof the chemical ingredients used therein, and processing of the data collected.
*1 REACH: Registration, Evaluation, Authorization and Restriction of Chemicals*2 SVHC: Substances of Very High Concern*3 BOM: Bill of Materials

 Joint Efforts with Suppliers
As required by various measures such as the European Union’s RoHS directive, specificallydesignated harmful chemical substances occurring in products must be controlled. Eachcompany in the supply chain must implement efforts to ensure proper control of the chemical
substances found in various products.
As part of these efforts, we have developed an evaluation tool that promotes the proactive
control of chemical substances occurring in products among the suppliers themselves. To
ensure PMR*4 assessments, we distribute supplier assessment check forms to our suppliers.
These forms are used to control various chemical substances occurring in products.
Alongside spot inspections by Tianma Japan, such efforts improve supplier control systems
by enabling supplier self-assessments.

Preventing Global Warming(Promoting Energy Conservation)
Recognizing global warming as an important environmental issue, we promote a wide
range of efforts to reduce carbon-dioxide emissions, including reductions in energy
used by plants, turning off lights when not needed, and using air-conditioning system
in energy conservation mode at our offices.
In addition, we are developing energy-saving measures that utilize subsidies forpromotion projects such as the introduction of energy-saving equipment for Akita city
small-and-medium sized companies person.
■ Examples of utilizing the subsidy program for promoting the adoptionof energy-conservation equipment at SMEs, etc.

1. Installing inverters on cooling water pumps for absorption refrigerators
Previously, these cooling water pumps had operated at fixed speeds regardless of thenumber of absorption refrigerators in operation. This project, however, reduced electricity
use by using inverters to control the volume of cooling water in accordance with thenumber of units in operation.
2. Installing inverters on scrubber exhaust fans
These fans had been used to control suction pressure through the intake of outside air
while operating at fixed speeds. This project reduced electricity use by discontinuing theintake of outside air and using inverters to control suction pressure instead.

3. Installing inverters on cooling water pumps for air conditioning in the main building
Previously, these cooling water pumps had operated at fixed speeds regardless of theoperational status of the air conditioners inside the main building. This project reduced
electricity use by using inverters to control the volume of cooling water in accordancewith the status of air-conditioner operation.

Controlling Chemical Substances
Various chemical substances are used in processes related to manufacturing andprocessing wastewater and exhaust gas emitted from manufacturing processes. For
purposes of monitoring environmental impact and control over handling safety, we
maintain a control structure of chemical substances, reduce the volumes of materials
used, and promote the transition to substances with lower levels of toxicity andenvironmental impact.

The Akita Plant continues to recycle all generated waste through waste segregationand the “three Rs” (reduce, reuse, recycle).
To ensure all waste is disposed of properly, waste processing is contracted out tolicensed, specialized waste processing firms. Final processing is confirmed using
manifests. In addition, waste-processing facilities are periodically subjected to on-site
inspections.
In 2017, allowed us to sell waste plastics and waste acids. Since then, these wastematerials have found effective use as raw materials.
