Soil Restoration: A Practical Climate Strategy

Why soil carbon storage matters for UK businesses

Soil restoration has emerged as a credible climate mitigation tool with commercial implications for UK businesses across agriculture, food production, and supply chain management. However, claims that it represents the fastest route to planetary cooling lack supporting evidence. The science points instead to soil carbon storage as a cost-effective, high-benefit strategy that can reduce atmospheric carbon dioxide while delivering operational advantages.

For businesses with land holdings, agricultural supply chains, or environmental commitments, this represents both an opportunity and a practical consideration. Healthier soils store more carbon and can function as carbon sinks when managed correctly. Moreover, these same practices often improve moisture retention, erosion resistance, and crop productivity.

The commercial reality is straightforward. Soil carbon sequestration offers tangible benefits beyond climate mitigation. Consequently, businesses exploring nature-based solutions should understand what the evidence actually supports and where the limitations lie.

The science behind soil carbon sequestration

Soil carbon sequestration describes the process of capturing and storing carbon in soils, thereby lowering atmospheric carbon dioxide levels. Columbia Climate School research confirms that better land management can increase soils’ capacity to store carbon. Furthermore, the same practices deliver measurable improvements in soil structure and function.

The Geological Society of America characterises soils as a proven and cost-effective strategy for climate mitigation. Their analysis indicates that regenerative agriculture can promote carbon sequestration while simultaneously improving soil health. Notably, this dual benefit distinguishes soil restoration from purely technical carbon reduction methods.

A 2017 estimate referenced by Columbia found that global croplands could store an additional 1.85 gigatons of carbon annually with improved management. This figure roughly equals annual emissions from the global transportation sector. The potential scale is therefore significant, though not unlimited.

Natural climate solutions, including soil-related approaches, have been estimated to provide a substantial share of cost-effective mitigation needed to restrict warming below 2°C. One review cited by the Geological Society of America suggests they could deliver 37% of required cost-effective carbon dioxide mitigation by 2030. These are material contributions, not marginal adjustments.

Management practices that increase soil carbon

Several agricultural practices have been shown to enhance soil carbon storage. Cover crops protect soil between main growing seasons and add organic matter when incorporated. Reduced tillage minimises soil disturbance, helping to preserve existing carbon stocks. Compost and manure additions directly introduce organic material that breaks down into stable soil carbon over time.

Restoring degraded land represents another important intervention. Previously damaged soils can regain carbon storage capacity through targeted management, though this process occurs gradually. The Geological Society of America notes that rebuilding degraded soils can be slow, making preservation of existing soil carbon a priority.

Avoiding land conversion and disturbance emerges as the most effective way to maintain soil organic carbon. Once soil carbon is lost through intensive tillage, conversion to development, or erosion, recovery takes years or decades. Therefore, protection of existing carbon-rich soils often delivers better results than attempting restoration after damage has occurred.

For UK businesses managing land or working with agricultural suppliers, these practices carry both environmental and operational implications. Improved soil health typically reduces input costs over time, increases resilience to drought or heavy rainfall, and can improve yields. However, transitions may require upfront investment and changes to established routines.

Commercial implications for UK businesses

Businesses with direct land holdings face the most immediate opportunities. Agricultural enterprises, forestry operations, and landowners can implement soil carbon practices while potentially qualifying for environmental subsidies under UK schemes. The Environmental Land Management scheme, for example, provides payments for actions that deliver environmental benefits including carbon storage.

Supply chain considerations extend these implications further. Food manufacturers, retailers, and hospitality businesses increasingly face questions about the carbon footprint of their supply chains. Consequently, sourcing from suppliers who employ regenerative agriculture practices can contribute to Scope 3 emissions reductions. This matters particularly for businesses pursuing Science Based Targets or responding to customer expectations on sustainability.

Public sector suppliers should note that carbon reduction increasingly features in tender evaluation. Procurement Policy Note 06/21 requires central government suppliers to publish carbon reduction plans and demonstrate progress. For businesses with significant land use in their operations or supply chains, soil carbon storage can form part of a credible reduction strategy.

Investment considerations also warrant attention. Nature-based solutions including soil restoration are attracting capital from investors seeking environmental returns alongside financial performance. Businesses with suitable land assets may find opportunities to generate revenue through carbon credits or environmental markets, though these markets remain developing in the UK context.

Nevertheless, soil carbon storage should not be treated as a substitute for emissions reduction at source. Columbia Climate School research explicitly states that the best way to combat climate change remains reducing fossil fuel use and shifting to renewable energy. Soil carbon storage functions as a complementary strategy, not a replacement for operational decarbonisation.

Important facts about soil and climate mitigation

• Soil carbon sequestration captures and stores carbon in soils, reducing atmospheric carbon dioxide levels through natural processes.
• Global croplands could potentially store an additional 1.85 gigatons of carbon annually with improved management, equivalent to emissions from the global transportation sector.
• Natural climate solutions including soil restoration could provide 37% of cost-effective carbon dioxide mitigation needed by 2030 to limit warming to 2°C.
• Key management practices include cover crops, reduced tillage, compost additions, manure incorporation, and restoration of degraded land.
• Avoiding land conversion and minimising soil disturbance remains more effective than attempting restoration after damage has occurred.
• Rebuilding degraded soils is possible but slow, making preservation of existing soil carbon a priority for immediate climate benefit.
• Reducing fossil fuel use and transitioning to renewable energy remains the primary climate solution, with soil carbon storage as a valuable complement.

What UK businesses should consider

Businesses evaluating soil carbon storage should begin with a clear assessment of their relationship to land use. Direct landholders have the most obvious opportunity, but supply chain connections and procurement requirements create indirect pathways as well. Understanding where soil carbon fits within your broader carbon reduction strategy is essential before making commitments.

For agricultural businesses, the transition to regenerative practices requires planning and often technical support. Our net-zero program for carbon reporting compliance helps businesses understand their baseline emissions and identify where nature-based solutions contribute most effectively. Soil carbon storage works best when integrated with other reduction measures, not pursued in isolation.

Supply chain managers should engage with agricultural suppliers to understand current practices and explore opportunities for improvement. This conversation has commercial value beyond carbon reduction. Suppliers using regenerative practices often demonstrate better resilience to weather variability and input price fluctuations. Consequently, soil health correlates with supply chain reliability.

Public sector suppliers preparing carbon reduction plans should consider whether soil carbon storage applies to their operations. If your business manages land, operates agricultural facilities, or sources significant volumes of agricultural products, soil carbon may feature in your Scope 1 or Scope 3 footprint. Our ESG compliance and carbon reporting services can help determine whether this applies to your circumstances.

Businesses exploring environmental markets or carbon offsetting should approach soil carbon credits with appropriate caution. The UK market for soil carbon credits remains immature, with questions about permanence, measurement, and verification still being resolved. While opportunities exist, they require careful evaluation and specialist advice.

Training and skills development will prove necessary for many businesses. Understanding soil carbon sequestration, measurement methodologies, and reporting requirements takes time. Resources available through SBS Academy training on environmental management can build internal capacity to assess and implement soil carbon strategies effectively.

The timeline for results matters as well. Soil carbon storage builds gradually over years, not months. Businesses seeking immediate carbon reductions should prioritise operational efficiency and energy transitions. Soil carbon storage delivers long-term benefits but should not be relied upon for short-term carbon reduction targets.
