Carlsberg funds WWF-UK and the Norfolk Rivers Trust to build on-farm sediment traps with East Anglian barley growers; a 2025 impact report found three monitored traps returned over 14 million litres of water and cut sediment reaching local rivers.

Context

Carlsberg sources barley from East Anglia, where intensive arable farming on chalk catchments contributes sediment and diffuse pollution to rivers such as the Wensum and Blackwater. In 2023 Carlsberg committed an initial £150,000 to WWF-UK to help selected farmers replenish freshwater and improve water-sensitive farming practices, with the Norfolk Rivers Trust engaged as the delivery partner working directly with growers.

Activities

The Trust's core intervention is supporting farmers to build on-farm sediment traps that capture eroded soil and pollutants before they reach watercourses, alongside wider water-sensitive farming advice. Carlsberg and WWF publicised a target of replenishing up to 100 million litres of freshwater through the partnership.

Results

A joint Carlsberg/WWF impact report published in April 2025 quantifies results from three monitored sediment traps: a combined 14,437,845 litres of water returned to the environment, and statistically significant reductions in sediment reaching the River Blackwater from both road verges and eroded topsoil after installation.

Conclusions

The evidence base remains narrow: only three traps have published monitoring data, the programme is funded through voluntary corporate philanthropy rather than a market or regulatory PES mechanism, and its record covers barely two growing seasons, so transferability beyond this single supply chain is not yet demonstrated.

Implementation
Indicative cost
Low (< €50k) — £150,000 initial Carlsberg commitment to WWF-UK (2023) funding on-farm sediment traps and water-sensitive farming advice delivered via the Norfolk Rivers Trust; no separate per-trap cost is given.
Time to results
Short (< 1 year) — Partnership launched in 2023; the first impact report, covering roughly two growing seasons, was published in April 2025.
Staffing & skills
Carlsberg Group (funder), WWF-UK (programme partner), Norfolk Rivers Trust (delivery partner working directly with growers)

Conditions for success

  • Corporate funding tied to supply-chain sustainability (barley sourcing from East Anglia)
  • Delivery through an experienced local river trust working directly with farmers
  • On-farm sediment traps as a concrete, practical intervention
  • Published impact monitoring and reporting

Common failure modes

  • Narrow evidence base: only three traps have published monitoring data
  • Funded via voluntary corporate philanthropy rather than a market or regulatory PES mechanism, so continuity depends on continued corporate commitment
  • Short record (about two growing seasons) means transferability beyond this single supply chain is unproven
