Operational Boundaries

According to GHG protocol, 3 different scopes are defined:

• Scope 1: Direct GHG emission, which includes stationary combustion

unit such as boiler, furnace etc and company owned mobile combustion unit like vehicles, ships etc.

• Scope 2: Indirect GHG emission, such as purchased electricity, heat

and steam.

• Scope 3: Other indirect emission, activities covers business travel,

employee commute, emission from non company owned vehicles, waste disposal. (Scope 3 is optional)

Offsets / Renewable Energy

Solutions for a living planet

Offsets / Renewable Energy

• Offset

After the company maximizes its energy efficiency and takes steps to reduce its GHG emissions, it may choose to purchase carbon offsets to further mitigate its impact on climate change. Within the LCMP purchasing carbon offsets is encouraged only after all other measures for reducing GHG emissions on site have been exhausted. In the labeling structure of the LCMP this means that acknowledgement of

• ffsets purchased will only happen if the company has already achieved

a Platinum label.

• Renewable Energy Application

In LCMP software, user can also input data of application of renewable

• energy. This is calculated based on the electricity saved by using

renewable energy.

Solutions for a living planet

GHG Management System

• To identify and manage the risks and opportunities

associated with GHG emissions.

• Extends beyond traditional energy efficiency and

includes every aspect of an organization’s performance in relation to climate change.

• Based on the ISO 14001 standard for environmental

management systems, also follows a structure for energy management

• Contributes 35% to the overall score for determining

the label rating

Best Practice in Electronics Industry

• An essential part of the LCMP label is the assessment
• f the current state of process technologies and

utilities in the participating factory against the relevant energy efficiency best practices.

• There is 2 main areas of Best Practice in LCMP:

(1) General Utilities (2) Industry-specific production facilities

• Contributes 40% to the overall score for determining

the label rating

Solutions for a living planet

General Utilities

• Use clean fuel, such as LPG or petroleum
• Proper installation of steam pipes

Steam System

• Suitable type and size of compressor
• Heat Recovery system

Compressed Air System

• Good lighting design / lighting control
• High efficiency lights, such as T5 florescent tube
• r LED

Lighting System

• Voltage balancing device
• Optimization of cable size

Electrical System

• VSD for optimization of fans and pump speed
• Set control valves for individual zone
• Energy recovery technologies

HVAC System

• Focus on System Design and Operation & Maintenance

Solutions for a living planet

Checklist of General Utilities

Allowing automatic variable cooling/heating according to the actual cooling/heating needs (e.g. use of VRV or VAV system) PER-1.7 Provision of energy recovery in HVAC system PER-1.6 Energy efficient heat rejection method of central A/C plants PER-1.5 Allowing pump speed optimization PER-1.4 Proper location of exhaust systems PER-1.3 Proper control of pre-treated fresh air supply PER-1.2 Allowing fan speed optimization PER-1.1

Solutions for a living planet

Industrial-specific production facilities

Common Best Practices to all the processes

• Optimization of machine performance, such as

machine capability study, machine efficiency, repeatability, maintenance….etc.

• Avoid to use agents with GHG emissions
• Minimize the defect rate and rework

Solutions for a living planet

Industrial-specific production facilities

Optimization of process parameters in PCB design, pattern imaging, lamination, drilling, plating, solder mask & silk screen printing, surface finishing…etc. PCB Optimization of process parameters in Component Lead Preparation (wiring width & length…), Component Insertion (head pressure, workflow…), Wave Soldering processes (temperature profile, conveyor speed…) Through Hole Assembly Optimization of process parameters in Solder Paste Printing (printing speed & pressure…), Component Placement (head pressure, displacement…) and Reflow Soldering processes (temperature profile, conveyor speed…) SMT
