How SMEs Can Set Science-Based Targets with SBTi: 4 Net Zero Roadmap Steps

For many SMEs, net zero can feel like a shifting goal. Energy costs are unpredictable,

customer expectations are increasing, and sustainability reporting obligations continue to

grow year by year. Larger organisations are now asking suppliers, including smaller

businesses, to demonstrate measurable progress on decarbonisation, not just long-term

promises.

The strongest net zero roadmaps are built on clear, evidence-based roadmaps. Aligning your

approach with frameworks like the SBTi gives your commitments real weight.

This guide explains what the Science Based Targets initiative (SBTi) is, why it matters, and the

steps SMEs can take to set science-based targets. It also outlines how specialist net zero

consulting services, like Tritility, can help you build a practical and credible Net Zero Roadmap.

What is the Science Based Targets initiative (SBTi)?

The SBTi is a global partnership designed to help organisations set greenhouse gas (GHG)

reduction targets aligned with climate science. While originally aimed at large multinational

organisations, SBTi now offers a simplified SME route, making it easier for smaller businesses

to validate their targets without the administrative burden of a full corporate submission.

For SMEs, SBTi validation offers independent assurance that your climate targets are

credible, measurable, and aligned with the expectations of modern supply chains.

Why SBTi Matters for SMEs

More businesses, including manufacturers, public sector bodies, and major retailers, expect

suppliers to demonstrate real emissions reduction progress. Validating science-based targets

gives SMEs:

• A recognised standard trusted by customers and partners
• Protection against greenwashing claims
• Competitive advantage in tenders and long-term contracts
• A clear structure for long-term decarbonisation planning

For many SMEs, acting early reduces future risk and strengthens commercial relationships.

Step 1: Measure Your Emissions with Carbon Accounting

Every credible Net Zero Roadmap begins with establishing your carbon footprint. Most SMEs

measure emissions across:

• Scope 1: Direct emissions from fuel use, boilers, and company vehicles
• Scope 2: Electricity, heat, and steam purchased from third parties
• Scope 3: Indirect emissions from supply chains, business travel, waste, logistics, materials, and distribution

Scope 3 often represents the largest share of emissions, particularly for manufacturers and

logistics-based businesses, but you don’t need precise data to start. Initial high-level

estimates are enough to identify hotspots and plan reductions. You can learn more about Scope 3 in our blog “Scope 3 Emissions Requirements: Everything Your Business Needs to Know”.

This is where carbon accounting services streamline the process, ensuring data is accurate,

consistent, and aligned with recognised reporting frameworks.

Step 2: Set Science-Based Targets Aligned with SBTi

Once your emissions baseline is in place, the next step is to set targets that align with SBTi

standards. The SME pathway requires:

• A minimum 50% reduction in Scope 1 and 2 emissions by 2030
• A commitment to measure and reduce Scope 3 where these emissions are material

Although this may feel ambitious, most SMEs find that the majority of reductions come from a

focused set of actions, equipment upgrades, energy efficiency improvements, renewable

electricity, and fleet electrification.

A specialist net zero consulting partner can help you prioritise which areas to tackle first.

Step 3: Build a Practical and Phased Net Zero Roadmap

A strong Net Zero Roadmap balances ambition with practicality. The most effective plans

Combine:

Immediate Low-Cost Opportunities

Quick wins such as LED lighting, compressed air optimisation, equipment controls, and

behaviour change initiatives. These create early carbon and cost savings that build

momentum.

Medium-Term Investments

Projects such as solar generation, equipment replacement, process optimisation, or low-

carbon heating systems.

Long-Term Transformational Changes

Electrification of transport, supply chain engagement, deeper process redesign, and long-

term capital projects.

Alongside the technical measures, embedding sustainability into procurement, staff training,

and day-to-day operational decisions are essential for long-term success.

Step 4: Strengthen Your Carbon Emissions Reporting

Once goals are set, accurate carbon emissions reporting ensures ongoing transparency. SMEs benefit from:

• Annual GHG reporting
• Clear Scope 3 methodologies
• Active supplier engagement
• Energy monitoring and analytics
• Benchmarking and performance tracking

This ensures your Net Zero Roadmap remains credible and aligned with SBTi expectations.

Why SMEs Should Act Now

Delaying action increases risk. SMEs that cannot evidence credible emissions reductions may

lose out on tenders or struggle to access cost-saving opportunities. Meanwhile, early movers

benefit from:

• Stronger supply chain positioning
• Long-term energy cost reductions
• Greater access to funding and support
• Competitive differentiation
• Better preparedness for future regulation

Acting now helps businesses stay resilient and commercially attractive in an increasingly

sustainability-focused market.
