Organization Boundaries






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 mobilecombustion 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


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 offsets 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.


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


Elements of GHG Management System

• Greenhouse Gas (GHG) Policy

• GHG Targets and Management Program

• Implementation and Operation

• Checking and Corrective actions


GHG Policy

Relevant Laws

Policy as Foundation

Does the company have a clear policy statement on GHG emissions pertaining to its activities? Provide reference on the content of this statement, where it can be found and if it is public.

GHG Targets & Management Program

GHG Aspects

TargetsManagement

Program

Has the company identified significant GHG/energy aspects of the operating processes, including all energy carriers and other GHG sources within its operational control? Does the company have a (complete) list of direct GHG emission sources within its operational control?

Identification of activities that impact on GHG emissions

2.1.1

A GHG aspect refers to an aspect of an activity within the company's organisationalcontrol that has a positive or negative effect on GHG emissions.

Control

Have the tasks, responsibilities and authority on various levels of the company been clearly defined and documented? Provide reference to the documentation describing and allocating responsibility for the GHG management system implementation. If no documentation exists, but there is a clear practice in the company then describe the current practice and explain if it is durable.

Best Practice in Electronics Industry

• An essential part of the LCMP label is the assessment of 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


General Utilities

- Use clean fuel, such as LPG or petroleum

- Proper installation of steam pipesSteam

System

- Suitable type and size of compressor

- Heat Recovery systemCompressed Air

System

- Good lighting design / lighting control

- High efficiency lights, such as T5 florescent tube

or 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

Industrial-specific production facilities

• Surface Mount Technology (SMT) Industry

• Through-Hole Assembly Industry

• Printed Circuit Board (PCB) Industry



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



Optimization of process parameters in PCB design, pattern imaging, lamination, drilling, plating, solder mask& silk screen printing, surface finishing…etc.

PCB
