How SMEs are forging ahead with sustainability in 2026

Sustainability experts spotlight SME action in new edie podcast

A new podcast episode from edie Extra examines how small and medium businesses are tackling sustainability challenges in 2026. Published on 17 April, the episode features Wendy Whewell from Santander and Tom Isler from Baxter Freight. Both experts explore practical approaches to overcoming common barriers facing smaller firms.

The 29-minute discussion focuses on finance, expertise gaps, and awareness issues. These obstacles have historically held back SME progress on environmental goals. However, the conversation highlights tangible actions businesses can take right now. Topics include green finance options and sustainable logistics practices.

This episode builds on momentum from the edie 26 conference. Held in central London during March 2026, the event attracted over 950 environmental and governance professionals. Subsequent podcast episodes have unpacked themes raised at the conference. These include balancing sustainability with profitability during economic pressure and evolving departmental roles.

The timing matters because SMEs represent a substantial portion of UK business activity. Their collective environmental impact runs parallel to their economic importance. Consequently, helping these businesses move forward on sustainability targets directly affects national progress.

You can listen to the episode on SoundCloud, YouTube, Spotify, and Apple Podcasts. The format makes expert insight accessible to business owners wherever they prefer to consume content. Meanwhile, the focus remains practical rather than theoretical.

Why SMEs matter for UK emissions and economic targets

More than 5.5 million SMEs operate across the United Kingdom. These businesses generate over half of all business-related emissions in the country. At the same time, they employ 60% of the UK workforce. This combination creates both a challenge and an opportunity.

The challenge stems from resource constraints. Smaller businesses typically lack dedicated sustainability teams. They also face tighter budgets than larger corporations. Therefore, accessing specialist knowledge and funding becomes difficult. Many SME owners want to act but struggle to identify where to start.

The opportunity lies in scale. If a meaningful proportion of these 5.5 million businesses adopt even modest improvements, the cumulative effect would be significant. Small changes multiplied across millions of firms add up quickly. For example, switching to energy-efficient equipment or optimizing delivery routes reduces costs while cutting emissions.

Despite their importance, SMEs have lagged behind larger firms in environmental, social, and governance adoption. This gap persists partly because corporate ESG reporting requirements have focused on bigger companies. However, expectations are shifting. Supply chain pressure now flows downward from large buyers to smaller suppliers. Public sector procurement increasingly demands carbon reporting. In addition, customers increasingly favour businesses demonstrating environmental responsibility.

Wendy Whewell leads sustainable solutions and finance for corporate and commercial banking at Santander. Her role involves helping businesses access capital for green projects. Tom Isler serves as associate director of innovation and sustainability at Baxter Freight. His company specializes in sustainable freight solutions. Together, they bring complementary perspectives on finance and operational implementation.

Finance access remains a critical barrier for smaller firms

Many SMEs cite funding as their primary obstacle to sustainability investment. Upgrading equipment, improving buildings, or changing processes requires capital. Furthermore, smaller businesses often face higher borrowing costs than larger competitors. This situation creates a catch-22 situation where those who would benefit most from efficiency savings struggle to fund initial investments.

Santander and other lenders have developed products specifically targeting green improvements. These include preferential rates for energy efficiency projects or renewable installations. However, awareness of these options remains patchy. Many business owners simply do not know such finance exists. Others worry about application complexity or eligibility criteria.

The podcast addresses these concerns directly. Whewell explains how sustainable finance works in practice. She outlines what lenders look for and how businesses can strengthen applications. Importantly, she emphasizes that sustainability projects often deliver quick payback periods. Energy savings, waste reduction, and efficiency gains translate into ongoing cost reductions. Therefore, investments can be self-funding over time.

In addition to traditional lending, alternative finance models are emerging. Leasing arrangements for solar panels or electric vehicles reduce upfront costs. Energy service companies offer performance contracts where they fund improvements and share savings. Grant funding exists for specific sectors or technologies. Nevertheless, navigating these options requires knowledge that many small business owners lack.

The reputational benefits of sustainability action also carry economic value. Businesses demonstrating environmental responsibility often win customer loyalty. They may also gain competitive advantages in tenders, particularly for public sector contracts. Procurement Notice 06/21 requires suppliers bidding for large government contracts to report carbon emissions and have reduction plans. This requirement has created urgency among SMEs in supply chains.

Logistics sector innovation shows practical pathways forward

Baxter Freight operates in a sector facing intense pressure to decarbonize. Transport accounts for a significant share of UK emissions. Road freight contributes substantially to that total. Consequently, logistics companies must find ways to reduce impact while maintaining service levels.

Isler shares examples of innovation his company has implemented. These include route optimization software that reduces mileage. Vehicle specifications now prioritize fuel efficiency. Where possible, the company consolidates loads to maximize utilization. Each measure individually makes a small difference. Combined, they create meaningful reductions.

The podcast touches on how goods handling affects environmental performance. Different products require different approaches. Temperature-controlled freight consumes more energy than ambient goods. Fragile items need packaging that may increase waste. Therefore, understanding what customers ship helps identify the most relevant areas for improvement.

Electric and alternative fuel vehicles represent an obvious direction for freight operators. However, the business case depends on usage patterns. Urban delivery routes suit electric vans well. Long-haul operations still face range and infrastructure challenges. Accordingly, companies must match technology to specific applications rather than adopting blanket solutions.

Beyond vehicles, warehousing and facilities offer opportunities. LED lighting, motion sensors, and improved insulation cut energy use. Solar panels can offset grid consumption. Rainwater harvesting reduces water costs. These investments benefit from relatively short payback periods. Moreover, they continue delivering savings year after year.

Collaboration within supply chains amplifies impact. When shippers, carriers, and receivers work together, they can identify systemic improvements. Shared warehousing reduces empty running. Standardized packaging cuts waste. Digital documentation eliminates paper. These changes require coordination but benefit all parties.

What this means for businesses navigating sustainability requirements

The practical focus of this podcast reflects a maturing conversation around SME sustainability. Early discussions often emphasized why businesses should act. Now the emphasis has shifted to how they can act effectively. This change matters because it moves beyond aspiration toward implementation.

For businesses feeling overwhelmed, the podcast suggests starting with areas offering quick wins. Energy efficiency typically delivers measurable savings within months. Waste reduction cuts disposal costs immediately. These early successes build confidence and free up budget for larger projects. In addition, they demonstrate commitment to customers and employees.

Finance remains a genuine barrier but not an insurmountable one. Understanding available support mechanisms helps. Our compliance services can help businesses identify relevant funding and structure applications effectively. Many firms qualify for support they did not know existed. Furthermore, demonstrating a credible plan increases approval chances significantly.

Supply chain pressure will intensify as larger customers cascade requirements downward. Public sector suppliers already face carbon reporting expectations. Private sector procurement increasingly follows similar patterns. Consequently, businesses that act now gain advantages over those delaying. They avoid last-minute scrambles and can command premium positioning.

The logistics sector provides useful lessons for other industries. Optimization often costs little but delivers substantial benefits. Data-driven decisions identify wasteful practices. Technology adoption should match specific needs rather than follow trends. These principles apply equally to manufacturing, retail, hospitality, and professional services.

Collaboration emerges as a recurring theme. Businesses do not need to solve everything alone. Industry associations share knowledge. Peer networks provide support. Suppliers often help customers improve. Our SBS Academy offers training that builds internal capability while connecting businesses with others on similar journeys.

The reputational dimension deserves attention because it translates into commercial value. Customers increasingly choose suppliers based partly on environmental performance. Employees, particularly younger workers, want to work for responsible employers. Investors consider ESG factors when evaluating businesses. Therefore, sustainability becomes a business development tool rather than merely a cost centre.

However, authenticity matters enormously. Superficial claims invite scrutiny and damage trust. Genuine action backed by evidence builds credibility. Reporting progress honestly, including challenges faced, resonates more than polished perfection. Businesses should measure what matters and communicate clearly.

Where to find additional guidance and support

The edie Extra podcast episode is available on multiple platforms including SoundCloud, YouTube, Spotify, and Apple Podcasts. This accessibility ensures business owners can listen during commutes or while working. The edie.net website provides broader resources for sustainability professionals including news, analysis, and case studies.

For government guidance on SME sustainability, the Department for Energy Security and Net Zero publishes resources covering carbon reduction and net zero pathways. Their materials explain regulatory requirements and available support schemes. Additionally, the Greening Government Commitments outline public sector expectations that flow through to suppliers.

The British Assessment Bureau provides information on environmental management standards including ISO 14001. These frameworks help businesses structure their approach systematically. Meanwhile, the Institute of Environmental Management and Assessment offers professional development for those building expertise.

Businesses needing structured support with carbon measurement and reduction can explore our net zero program. This provides the frameworks and tools required for credible reporting. It also helps businesses identify priority areas and track progress over time. Importantly, it aligns with procurement requirements including PPN 06/21 for public sector suppliers.

Sector-specific guidance often proves most useful because it addresses particular challenges. Trade associations typically provide resources tailored to their industries. For example, logistics businesses can reference Logistics UK materials. Manufacturers can consult Make UK guidance. Retailers have British Retail Consortium resources. These organizations understand sector nuances better than generic advice.
