Climate action is no longer relevant only for large multinational corporations. Across Singapore and the wider region, small and medium-sized enterprises (SMEs) are increasingly being asked to disclose carbon emissions, respond to ESG questionnaires, and demonstrate how they plan to reduce greenhouse gas emissions.

Whether you are supplying multinational companies, participating in public tenders, or preparing for future sustainability reporting requirements, understanding your carbon footprint has become an important business capability.

The good news is that decarbonisation does not have to start with a complicated strategy. It begins with understanding your emissions, identifying practical reduction opportunities, and building a roadmap that fits your business.

Why Decarbonisation Matters for SMEs

Many SMEs assume carbon management is only necessary for large organisations. In reality, climate-related expectations are already flowing through supply chains.

Companies are increasingly asked to:

• Provide carbon emissions data

• Complete ESG questionnaires

• Demonstrate carbon reduction plans

• Support customer sustainability targets

• Improve tender competitiveness

Beyond compliance, decarbonisation also helps businesses:

• Reduce energy and fuel costs

• Improve operational efficiency

• Identify business risks

• Strengthen long-term resilience

• Prepare for future regulations

Understanding Scope 1, Scope 2 and Scope 3 Emissions

Every decarbonisation journey starts with understanding where emissions come from.

Scope 1 Emissions

These are direct emissions from assets owned or controlled by the company, including:

• Company vehicles

• Diesel generators

• Machinery and equipment

• Refrigerant leakage

  
  

Scope 2 Emissions

Scope 2 covers purchased electricity consumed by:

• Offices

• Warehouses

• Factories

• Construction sites

These emissions are generally the easiest for SMEs to measure using electricity bills.

Scope 3 Emissions

Scope 3 emissions occur throughout the value chain and may include:

• Purchased goods and services

• Construction materials

• Business travel

• Employee commuting

• Waste disposal

• Logistics

• Subcontractors

For most SMEs, the recommended approach is to establish a reliable Scope 1 and Scope 2 inventory first before progressively improving Scope 3 data.

How SBTi Supports SME Decarbonisation

The Science Based Targets initiative (SBTi) provides a recognised framework that helps companies move beyond carbon accounting.

Rather than simply calculating emissions, SBTi helps organisations:

• Establish a carbon baseline

• Identify major emission sources

• Set science-based reduction targets

• Develop practical decarbonisation initiatives

• Monitor progress over time

• Communicate climate commitments with confidence

For businesses in construction and the built environment, SBTi also supports improvements in fuel efficiency, energy management, procurement, supplier engagement and lower-carbon materials.

Building a Practical Decarbonisation Roadmap

An effective roadmap should translate climate ambition into practical business actions.

Typical stages include:

1. Measure your emissions

Develop a carbon inventory covering Scope 1 and Scope 2 emissions.

2. Establish a baseline

Understand where emissions are generated and identify the largest contributors.

3. Set reduction targets

Develop realistic emissions reduction targets aligned with business operations.

4. Implement reduction initiatives

Examples include:

• Energy efficiency improvements

• Fuel optimisation

• Renewable electricity

• Equipment upgrades

• Lower-carbon procurement

• Waste reduction

• Supplier engagement

5. Monitor and improve

Track progress annually and continually refine the roadmap as data quality improves.

Why SMEs Should Start Early

Businesses that begin their decarbonisation journey today will be better positioned to:

• Meet customer ESG expectations

• Strengthen tender competitiveness

• Improve operational efficiency

• Reduce climate-related business risks

• Prepare for evolving sustainability reporting requirements

Decarbonisation is no longer simply an environmental initiative—it is becoming an important component of long-term business strategy.
