What is SBTi and Why Are Businesses Racing Toward Science Based Targets?

Climate action is no longer a side conversation in business. Investors are asking for measurable sustainability strategies. Customers want transparency. Global supply chains are becoming more carbon-conscious. Governments are introducing stricter disclosure rules. And in the middle of this shift, one framework has rapidly become the gold standard for corporate climate credibility: SBTi.

The Science Based Targets initiative (SBTi) helps companies set emissions reduction targets that are aligned with climate science and global net-zero goals. Instead of vague sustainability promises, SBTi gives businesses a measurable and accountable path toward reducing greenhouse gas emissions.

Today, thousands of organizations across industries are adopting science-based targets because stakeholders no longer trust generic claims like “eco-friendly” or “carbon conscious.” Businesses are now expected to prove progress with real data, transparent reporting, and validated targets.

If you are trying to understand what SBTi means, why it matters, how it works, and whether your company should adopt it, this guide will help you understand everything in a practical and business-focused way.

What is SBTi?

The Science Based Targets initiative (SBTi) is a global organization that helps companies establish greenhouse gas reduction targets aligned with the latest climate science.

The initiative was created through collaboration between organizations including:

The primary goal of SBTi is to help businesses reduce emissions in line with the Paris Agreement and support the global transition toward a low-carbon economy.

In simple terms, SBTi answers one critical question:

“How much should a company reduce emissions, and by when, to help limit global warming?”

That scientific alignment is what makes SBTi different from traditional sustainability goals.

Why SBTi is Becoming a Business Priority

A few years ago, sustainability reporting was often optional branding. Today, it influences investor decisions, procurement eligibility, customer trust, and regulatory readiness.

Companies are increasingly adopting SBTi because it helps them:

Build climate credibility
Strengthen ESG performance
Improve investor confidence
Meet supply chain requirements
Prepare for future regulations
Reduce operational risks
Improve brand reputation
Gain competitive advantage

Many global corporations now require suppliers to establish science-based targets as part of procurement expectations. This means even mid-sized companies are entering the SBTi ecosystem to remain relevant in global supply chains.

How SBTi Works

The SBTi process is structured but practical. Companies follow a step-by-step approach to establish validated emissions reduction goals.

Step 1: Measure Current Emissions

Businesses first calculate their greenhouse gas emissions across:

Scope 1 emissions (direct emissions)
Scope 2 emissions (purchased energy)
Scope 3 emissions (value chain emissions)

Most organizations discover that Scope 3 emissions form the largest portion of their carbon footprint.

Step 2: Commit to Science Based Targets

Organizations publicly commit to setting science-based targets within a defined timeline.

This signals to stakeholders that the business is serious about climate action rather than making unsupported sustainability claims.

Step 3: Develop Reduction Targets

Companies create emissions reduction targets aligned with scientific methodologies and sector-specific pathways.

These targets may include:

Near-term reduction targets
Long-term net-zero targets
Renewable energy commitments
Supply chain decarbonization goals

Step 4: Validation by SBTi

The targets are reviewed and validated by SBTi experts to ensure they meet scientific requirements and framework criteria.

This validation step is what gives SBTi credibility in the global sustainability market.

Strategic Tip: Validation can take several months due to high demand. If you are preparing for a specific reporting cycle or a major supply chain tender, we recommend initiating your target setting and data preparation at least 6–9 months in advance.

Step 5: Implementation and Reporting

After validation, businesses begin implementation and disclose progress regularly through sustainability reports, ESG disclosures, or climate reporting frameworks.

Note for Small and Medium Enterprises (SMEs): You don’t always need the full, complex validation process. The SBTi offers a “Streamlined Route for SMEs” that allows smaller businesses to set near-term, science-based targets without the standard, more rigorous validation steps. If you have fewer than 500 employees and aren’t in a high-impact sector, this is often the fastest way to get started.

Understanding Scope 1, Scope 2, and Scope 3 Emissions

One of the biggest reasons businesses struggle with SBTi is confusion around emissions categories.

Scope 1 Emissions

These are direct emissions generated from company-controlled operations.

Examples include:

Fuel combustion
Company-owned vehicles
Manufacturing operations

Scope 2 Emissions

These are indirect emissions from purchased electricity, steam, heating, or cooling.

Electricity usage in offices or factories usually falls under Scope 2.

Scope 3 Emissions

These are indirect emissions across the value chain.

Examples include:

Supplier emissions
Business travel
Logistics
Product use
Employee commuting
Waste disposal

For many organizations, Scope 3 can represent over 70% of total emissions.

Why Scope 3 Emissions Matter So Much

The business world is rapidly moving toward value-chain accountability.

Large corporations are increasingly evaluating suppliers based on carbon performance. This means businesses without emissions data or reduction plans may face:

Procurement disadvantages
Reduced partnership opportunities
ESG rating pressure
Investor concerns

That is why SBTi adoption is no longer limited to multinational corporations. Even growing businesses are now building carbon strategies to stay competitive.
