The British dairy industry is defining a common strategy to strengthen environmental sustainability without compromising food security, product affordability, or the economic viability of rural communities. The Dairy Roadmap has presented "Sustainable Dairy Pathways: The Path to 2030," an independent report that identifies the actions needed to make the sector more resilient to climate change. The document comes after a summer marked by extreme temperatures, severe weather pressure, and the persistent spread of bluetongue.
Commissioned by The Dairy Roadmap on behalf of the entire value chain and conducted by Scotland's Rural College, the study brings together farmers, processors, and other stakeholders for the first time around a shared path. The central message is that the sector already knows many of the necessary solutions and must now focus on deploying them more widely. The plan builds on the results achieved in recent decades, during which on-farm emissions per liter of milk produced have decreased by approximately 22% since 1990.
Over the same period, methane emissions from the sector have dropped by almost 14%, while greenhouse gas emissions have decreased by 9% overall over the last five years. Significant progress has also been made in processing, where energy intensity has been reduced by over 30% and water use per kilogram of milk has dropped by more than half.
Furthermore, the share of waste sent to landfill, which previously reached 24%, has been reduced to below 2%. The report identifies four priorities to consolidate these results and accelerate change by the end of the decade. The first is to increase the adoption of practices already available and capable of producing measurable environmental benefits without penalizing livestock productivity.
The second concerns investments in more effective infrastructure and technologies, while the third calls on the sector to prepare for the innovations that may emerge in the coming years. The fourth priority is creating favorable conditions through coherent policies, accessible financial instruments, common data collection systems, and more widespread advisory services.
Achieving the transition described in the study would require a total investment of £2,4 billion. A significant portion of the resources should be allocated to the management and storage of slurry, an area requiring public support, clear regulations, and targeted interventions. The strategy also emphasizes the need to improve knowledge transfer, develop new skills, and make data collected along the supply chain more comparable.
According to Bas Padberg, president of The Dairy Roadmap, sustainability must be considered a tool for securing the future of dairy farming, not just a set of environmental obligations. "For the first time, the entire dairy value chain has come together around a shared path to 2030," Padberg stated. He emphasized that many solutions are already available and that the priority must be to expand proven practices. The report thus seeks to reconcile improved environmental performance with the efficient production of nutritious and affordable food.
Milk and its derivatives remain central to British dietary habits, having been purchased by 99,6% of households in the last year. The sector's importance is also evident in its production and employment figures. The United Kingdom produces approximately 15 billion liters of milk each year, and the sector supports more than 50 jobs directly on farms. In addition, another 22.500 are employed in dairy processing.
The sector therefore represents an important component of national food security and the economies of many rural areas. David Homer, chair of the Sustainable Dairy Pathways working group, noted that last summer's extreme heat clearly demonstrated the risks posed by climate change. High temperatures, weather events, and diseases like bluetongue are already impacting animal welfare, productivity, and companies' ability to weather crises. For Homer, the report's value lies primarily in building a collective vision, based on evidence, recommendations, and proven actions.
The goal is to develop a low-emission dairy system that is climate-resilient and contributes to nature conservation. However, this path must simultaneously preserve food availability, the economic sustainability of businesses, and the social role of farming communities. "Sustainable Dairy Pathways" is the first of two reports commissioned by The Dairy Roadmap, while a second document, expected in 2027, will define the longer-term trajectory towards 2050.
