Carbon accounting is becoming a cornerstone of Environmental, Social, and Governance (ESG) strategies across the UK. While traditionally associated with large corporations, it’s increasingly relevant for businesses of all sizes and sectors.

Large enterprises and listed companies

Publicly listed companies and large enterprises are often subject to mandatory carbon reporting under frameworks like Streamlined Energy and Carbon Reporting (SECR) and Task Force on Climate-related Financial Disclosures (TCFD). For these organisations, carbon accounting is essential for regulatory compliance, investor transparency, and risk management.

Businesses in high-emission sectors

Companies in sectors such as manufacturing, construction, transport, energy, and agriculture typically have higher carbon footprints. Carbon accounting helps these businesses identify emission hotspots, reduce costs through efficiency improvements, and meet industry-specific sustainability targets.

SMEs in supply chains

Small and medium-sized enterprises (SMEs) that supply goods or services to larger firms are increasingly required to report emissions data. Many corporates are extending ESG requirements to their supply chains, making carbon accounting a competitive advantage for SMEs seeking to win contracts or maintain partnerships.

Service-based and tech companies

Even businesses with low direct emissions—such as professional services, finance, and tech—can benefit from carbon accounting. Scope 3 emissions, including employee travel, cloud computing, and purchased goods, often make up the bulk of their footprint. Tracking these supports net-zero goals and enhances ESG credibility.

Startups and seed-stage businesses

Early-stage companies that embed carbon accounting from the outset are better positioned to scale sustainably, attract ESG-conscious investors, and future-proof their operations. It also opens doors to green banking products, including sustainability-linked loans and preferential financing terms for low-carbon initiatives.

Purpose-driven and consumer-facing brands

Brands that market themselves on sustainability or serve eco-conscious consumers, such as BCorp-certified businesses should use carbon accounting to validate claims and avoid greenwashing. Transparent reporting builds trust, strengthens brand reputation, and aligns with the values of ethically minded stakeholders.
