What is SIRIM Karbon Kalkulator?

The SIRIM Karbon Kalkulator is a web-based tool for collecting information on the life cycle of construction and building materials in Malaysia, and now also of agricultural and metal industry products. Companies can use the tool to calculate the carbon footprint of their products, enabling them to gain reputational benefits through a SIRIM-sponsored carbon label, and become better informed on reducing their environmental impact.

Development of the Product Carbon Footprint Calculator by SIRIM Berhad

The carbon footprint of a product or service is the total amount of carbon dioxide (CO2) and other greenhouse gases emitted over its life cycle. Determining it involves a Life Cycle Assessment (LCA) study focused on greenhouse gas emissions, starting from the raw material acquisition stage, through the production and use stages, to final disposal. The results are usually presented as carbon dioxide-equivalent (CO2-e) emissions, measured in kilograms or metric tonnes.

A carbon footprint calculator is needed to support the calculation and certification of product footprints. In this project, a toolkit called the SIRIM Karbon Kalkulator was developed to automate the calculation procedure, and to be used by the auditor to verify the calculation process.

The SIRIM Karbon Kalkulator consists of several elements

  • Input and output dataA compilation of the input and output data of a product over its life cycle.
  • Data entry frameworkA framework that enables users to enter their primary data quickly and easily.
  • Secondary databaseSecondary data sourced from MYLCID (Malaysia Life Cycle Database), ILCD (International Life Cycle Database) and any other source that complies with the criteria in the document Criteria Acceptance of SIRIM Karbon Kalkulator Database.
  • Guidance documentInformation and rules on how to collect data and use the calculator to calculate the carbon footprint of products or services.
  • Activity calculatorsCommon activities such as transportation, disposal of waste to landfill at end of life and storage at distribution centres have their own calculators in separate spreadsheets.

Model framework

The carbon footprinting process and the calculator

Carbon footprinting a product involves a significant investment of time and resources. The calculator organises the work into one framework.

Data needs to be collected from a variety of activities such as raw material extraction, energy and utility consumption, transportation and waste disposal. These primary data are collected by the company within its operational control, according to the relevant system boundary, using the PDS (Product Data Sheet) form: a series of questionnaires covering the input and output data of the product's life cycle, from cradle to grave. Sometimes secondary data (such as national averages) also need to be collected to characterise the upstream and downstream processes for which primary data are not easy to obtain.

Because carbon footprinting means handling a lot of data, a framework is needed to organise the data into categories and link each one to its emission factor to produce the final footprint. The SIRIM Karbon Kalkulator was developed to simplify this: it uses the data and information from the PDS form to calculate the carbon footprint of the product, based on its goal and scope definition.

Carbon footprint values can differ considerably from product to product within the same product category, but the calculation procedure is the same. A common reference flow is decided at the start of the calculation, from the raw material phase right up to the disposal phase. The data and information gathered in the toolkit are also used by the auditor during the audit to reassess the calculation procedure and the validity of the corresponding data.

Footprint with CO2Carbon footprint, explained

What is carbon footprint?

The carbon footprint of a product is the sum of greenhouse gas emissions and removals in a product system, expressed as CO2 equivalent and based on life cycle assessment (LCA).

What is CO2 equivalent?

The CO2 equivalent is a calculated mass for comparing the radiative forcing of a greenhouse gas to that of carbon dioxide. It is the mass of a given greenhouse gas multiplied by its global warming potential (GWP).

mass of gas×GWP=kg CO2e

Over the whole life cycle

The footprint follows greenhouse gas emissions from raw material acquisition, through production and use, to final disposal. Results are presented as CO2-e emissions in kilograms or metric tonnes.

Life cycle assessment ISO 14044

According to ISO 14044, life cycle assessment is the compilation and evaluation of the inputs, outputs and potential environmental impacts of a product system throughout its life cycle. There are four main phases in LCA:

1

Goal and scope definition

An LCA starts with an explicit statement of the goal and scope of the study, which sets out its context and explains how and to whom the results are to be communicated. This is a key step: the ISO standards require the goal and scope to be clearly defined and consistent with the intended application.

2

Life cycle inventory analysis

The phase that compiles and quantifies the inputs and outputs for a product through its life cycle.

3

Life cycle impact assessment

The phase aimed at understanding and evaluating the magnitude and significance of the potential environmental impacts of a product system throughout the life cycle of the product.

4

Life cycle interpretation

The phase in which the findings of the inventory analysis, the impact assessment, or both, are evaluated against the defined goal and scope to reach conclusions and recommendations.

Choose your system boundary

Every product is assessed within a boundary: how much of its life cycle the footprint covers.

2008

LCA Malaysia

LCA Malaysia was created in 2008, in connection with the National LCA Project for the establishment of a national life cycle assessment (LCA) database. The effort was mandated to SIRIM Berhad by the Government of Malaysia under the Ninth Malaysia Plan (2005–2010), to support a cleaner production approach in the country's industrial activities.

Its ultimate goal is to bring together the different players, namely practitioners, software developers, users, decision-makers, students and the public at large, in LCA activities for sustainable development.

Glossary

The terms you will meet

Definitions of the words used throughout the calculator and its reports.

LCALife cycle assessment
Compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle.
CO2Carbon dioxide
A naturally occurring chemical compound that is a gas at standard temperature and pressure, and exists in the Earth's atmosphere in this state as a trace gas at a concentration of 0.039 per cent by volume. As part of the carbon cycle, plants, algae and cyanobacteria use light energy to photosynthesise carbohydrate from carbon dioxide and water, with oxygen produced as a waste product.
CO2eCarbon dioxide equivalent
Calculated mass for comparing the radiative forcing of a greenhouse gas to that of carbon dioxide. The carbon dioxide equivalent is calculated by multiplying the mass of a given greenhouse gas by its global warming potential.
GWPGlobal warming potential
Characterisation factor describing the mass of carbon dioxide that has the same accumulated radiative forcing over a given period of time as one mass unit of a given greenhouse gas.
GHGGreenhouse gas
Gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, the atmosphere and clouds. Water vapour and ozone are anthropogenic as well as natural greenhouse gases, but are not included as recognised greenhouse gases because, in most cases, it is difficult to isolate the human-induced component of global warming attributable to their presence in the atmosphere.
PDSProduct Data Sheet
A series of questionnaires covering the input and output data related to the life cycle of a product, from cradle to grave. The calculator works out the footprint from it.
