After years of building momentum, sustainability in grocery retail has reached a defining phase. 

Timelines are tightening, the cost of delay is harder to absorb, and the pace of change demanded by shoppers, regulators, and vulnerable supply chains is intensifying.  

However, there are also commercial imperatives. Sustainable retail businesses have better financial outcomes, enjoy stronger customer loyalty, and have better margin stability. 

In 2026, only collaborative, decisive action will be enough to deliver meaningful change. Businesses recognising this will shape the future of sustainability retail and the global food system. They will also determine who leads it.

Sustainability and commercial performance are now inseparable

The commercial case for sustainability has strengthened considerably. Efficient operations save resources and reduce waste. Better transparency lowers exposure to long term risks. Strong sustainability performance builds trust, supports shopper loyalty, and helps businesses adapt to volatility in supply and cost. 

Far from being a cost burden, sustainability is becoming a driver of resilience and growth. The organisations that understand this are moving beyond compliance and embedding sustainable thinking into strategic planning, operational models and culture. 

However, while this is the carrot of a commercial imperative, there is also the stick of a regulatory imperative.

Sustainability legislation is expanding rapidly 

Governments around the world are introducing stricter rules on packaging design, recyclability, emissions reporting, and food waste. What were once advisory frameworks are becoming mandatory requirements with financial consequences for non-compliance. 

This shift is already influencing how products are designed, how materials are sourced, and how supply chains are structured. It is also reshaping investment decisions and internal capabilities.  

The expectation is no longer that businesses simply comply; they must demonstrate that their systems can keep pace with evolving rules, provide transparent data, and adapt quickly as standards continue to evolve. 

For many organisations, this will require a step change in readiness, supported by a more integrated approach to sustainability across functions. The companies that respond quickly will be better positioned to absorb cost pressures, maintain trust, and stay ahead of regulatory scrutiny. 

Shoppers expect action 

Shoppers are an increasingly decisive force in sustainable retail. Many are changing habits to reduce their environmental impact, and sustainability is now a meaningful factor in their purchasing decisions with around 80% globally saying that sustainability is important to them.  

This shift is particularly evident in areas that shoppers can see and understand, such as packaging. Environmentally friendly formats are increasingly influencing product choice and shaping loyalty. 

Shoppers also want the industry to take the lead, expecting retailers and suppliers to make sustainable choices easier and show their businesses are “doing the right thing”.  

Credible, visible progress is becoming essential for maintaining trust and meeting the rising expectations that now shape demand across the food and grocery sector. 

The food system depends on collective action 

The challenges facing the food system cannot be solved in isolation. Supply chains are global, interconnected, and influenced by decisions made across multiple sectors and regions. No retailer, manufacturer or supplier can meaningfully reduce environmental impact without working closely with others. 

Suppliers play a critical role in providing accurate data and transparency to help retailers meet reporting requirements and reduce emissions across the value chain. Manufacturers must continue to innovate in areas such as packaging, energy efficiency, and waste reduction. Retailers must influence demand, engage shoppers and create the conditions for industry wide progress. 

Climate related shocks, resource volatility and rising operational risks are already testing the resilience of supply chains. Only aligned action across the sector will create a system capable of weathering these pressures and supporting long-term growth. 

Collaboration will define the next phase of progress

Sustainability has often been approached independently, with each business focusing on its own targets and programmes. This approach is no longer enough. The next wave of progress will be driven by deeper partnerships, shared frameworks and coordinated investment. 

Joint learning, common reporting standards, collaboration with technology partners and cross-industry alliances can accelerate change far more effectively than individual action. These approaches reduce duplication, spread risk, and help innovative ideas scale faster.  

When organisations take shared responsibility for progress, the cumulative impact is significantly greater than anything achievable alone. 

Collaboration is no longer a secondary option. It is a competitive advantage.

Turning pressure into advantage 

This year brings heavy expectations and significant pressure to act; however, it also creates clear commercial opportunities.  

Businesses that move with pace, collaborate, and fully embed sustainability into everyday decision-making will not only benefit from meeting expectations, but will help shape a stronger and more resilient global food system for them to thrive in.
