Scope 1, 2, and 3 Emission Calculation Services In Accordance with International Standards

Calculating Scope 1, 2, and 3 emissions serves as a crucial first step for companies to understand their carbon footprint and the environmental impact of their operations. By quantifying Greenhouse Gas (GHG) emissions, companies can identify emission sources, devise reduction strategies, and comply with increasingly stringent environmental regulations. In an era of heightened global awareness regarding climate change, transparency in emissions management fosters trust among investors, customers, and other stakeholders. According to IPCC reports, the global temperature rise has already reached 1°C above pre-industrial levels; without concrete action, this increase could reach 1.5°C between 2030 and 2052. As a signatory to the Paris Agreement, Indonesia has committed to reducing emissions by 31.89% independently and by 43.2% with international support by 2030. By calculating Scope 1, 2, and 3 emissions, your company contributes to achieving these national targets.

Understanding Scope 1, 2, and 3 Emissions

Calculating Scope 1, 2, and 3 emissions involves categorizing greenhouse gas (GHG) emissions based on their sources, in accordance with the Greenhouse Gas Protocol (GHG Protocol) standards. Here is an explanation of each:

Scope 1: Direct emissions from activities owned or controlled by the company, such as fuel combustion in company vehicles, emissions from production processes, or refrigerant leakage from air conditioning systems. Example: emissions from a factory generator.
Scope 2: Indirect emissions from purchased energy—specifically electricity, heat, or steam—used by the company. Example: emissions from the power plant supplying energy to your office.
Scope 3: Other indirect emissions within the company’s value chain, such as raw material transportation, employee business travel, or product use by consumers. Scope 3 often represents the largest and most complex category.

Understanding these three categories enables companies to comprehensively measure their environmental impact and devise effective, targeted reduction strategies.

International Standards for Calculating Scope 1, 2, and 3 Emissions

The process for calculating Scope 1, 2, and 3 emissions refers to globally recognized international standards, namely:

Greenhouse Gas Protocol (GHG Protocol)

Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), the GHG Protocol is the most widely used standard for measuring and reporting GHG emissions. This standard includes guidelines for calculating Scope 1, 2, and 3 emissions, as well as for transparent reporting.

ISO 14064-1:2018

This standard provides guidance for organizations on measuring, monitoring, and reporting GHG emissions. ISO 14064-1 supports emissions accountability and verification and is often used in conjunction with the GHG Protocol.

IPCC Guidelines for National GHG Inventories

These guidelines from the Intergovernmental Panel on Climate Change (IPCC) provide methodologies for calculating emissions at national and organizational levels, particularly for the industrial and energy sectors.

These standards ensure that your emissions calculations are consistent, transparent, verifiable by third parties, and globally accepted.

Guidelines and Regulations in Indonesia

In Indonesia, guidelines for calculating Scope 1, 2, and 3 emissions are governed by regulations that support national commitments to emission reduction. The following are the latest guidelines and regulations:

Regulation of the Minister of Environment and Forestry (PermenLHK) Number 21 of 2022 concerning Procedures for the Measurement, Reporting, and Verification of GHG Emissions: This regulation mandates that companies in specific sectors—such as energy, manufacturing, and transportation—report their GHG emissions periodically. Updated in 2025, the regulation emphasizes the use of international standards such as the GHG Protocol and ISO 14064-1.
Presidential Regulation Number 98 of 2021 concerning the Implementation of Carbon Economic Value: This regulation governs carbon trading and incentives for companies that reduce emissions, including through the calculation of Scope 1, 2, and 3 emissions. As of 2025, carbon trading implementation in Indonesia has become increasingly active, supported by the Indonesian Carbon Traders Association.
Indonesia’s NDC (Nationally Determined Contribution) Roadmap: Established as part of the Paris Agreement to achieve more ambitious emission reductions, with a focus on the energy, waste, and forestry sectors.

These guidelines refer to the GHG Protocol and ISO 14064-1 to ensure compliance with both global and local standards. Companies can use web-based GHG emission calculators, such as the platform provided by Actia Carbon, to perform these calculations.

Benefits of Calculating Scope 1, 2, and 3 Emissions for Your Business

Calculating Scope 1, 2, and 3 emissions offers several benefits for your business, including:

Meeting regulatory obligations—such as those outlined in the Ministry of Environment and Forestry (LHK) regulations and the Presidential Regulation on Carbon Economic Value—thereby avoiding potential sanctions.
Transparent emissions reporting boosts investor confidence, particularly among those focused on ESG (Environmental, Social, and Governance) criteria.
Identifying emission sources helps companies devise effective strategies to improve energy efficiency and optimize operational costs.
Environmentally conscious companies are more attractive to sustainability-minded customers and business partners.
Companies can demonstrate their contributions and support the global net-zero target for 2050, aligning with Indonesia’s national commitment.

By calculating Scope 1, 2, and 3 emissions, you not only ensure regulatory compliance but also build a more sustainable and competitive business.
