428 John Gilliland - Why a top UK regen farmer hasn't sold his carbon yet
Fifth-generation farmer John Gilliland, a pioneer in regenerative agriculture from Northern Ireland, refuses to sell his carbon credits despite being certified carbon negative—because he doesn't trust the current voluntary carbon market. He argues that the market’s structure is fundamentally flawed: the same entities that verify carbon removal also act as judges and juries, creating a conflict of interest. Gilliland, who measures soil health down to one meter deep and uses aerial LIDAR for precision, insists that accurate, independent Measurement, Reporting, and Verification (MRV) is non-negotiable. His farm, a living lab with 250-year-old woodland suffering from lack of animal presence, proves that soil health is not just about carbon—it’s about resilience, nutrient cycling, and biodiversity. He reveals that 80% of his farm’s carbon is stored in soil, not trees, and that silvopasture systems outperform monocultures in drought, flood, and storm resilience. His message to investors? Stop chasing quick wins. Focus on long-term partnerships with land managers who measure rigorously, use science, and prioritize transparency over hype. The real crisis, he says, isn’t food production—it’s the failure to translate scientific knowledge into on-farm action. Gilliland’s core insight: regenerative farming isn’t about reducing yields—it’s about increasing resilience.
John Gilliland hasn’t sold a single carbon credit because he distrusts the voluntary market’s judge-and-jury structure—verifiers should not also be the buyers.
Soil organic carbon is a proxy for multiple soil functions: water infiltration, nutrient cycling, biodiversity, and climate resilience—measuring it deeply (to 1m) reveals 38% of carbon is stored below 30cm.
Silvopasture systems (trees + animals + diverse plants) outperform monocultures in drought, flood, and storm resilience, with 80% of farm carbon stored in soil, not trees.
A 36-hectare trial showed 42% more herbage, 83% more meat per hectare, and 65% less nitrogen use in one year—proving regenerative farming boosts productivity, not reduces it.
Farmers respond to language about nutrient cycling and climate resilience, not abstract 'soil health'—tailor messaging to audience: farmers care about input costs and weather extremes.

Why a Top UK Regen Farmer Won’t Sell His Carbon
“I'm not convinced they're there. I've been quite outspoken about that and that is why from our point of view, we as farmers set off, we say well what is the measurement we need to pick up the positive changes that we're doing in our landscape?”
The 250-Year-Old Woodland That’s Dying Without Animals
Gilliland’s ancient woodland, fenced off for 250 years, has lost all earthworms, pH dropped to 4.8, and trees are failing due to lack of animal-driven microbiome inoculation and lime application.
Soil Health Is a Proxy for Resilience, Not Just Carbon
Soil organic carbon is a proxy for water infiltration, nutrient cycling, and root activity. Gilliland measures down to 1m and finds 38% of carbon is deeper than 30cm—something most MRV systems miss.
The Real Crisis: Translation of Science to Practice
“The investment in knowledge exchange is awful right across Europe... We have any amount of research projects. We have heaps of publications sitting on shelves, but its translation into usable knowledge... is woeful.”
Regenerative Farming Delivers More, Not Less
“We increased herbage by 42% in a year, while reducing nitrogen by 65%. We increased meat output by 83% per hectare. Wow. And that was through regeneration. Okay? In one year.”

“That is my one wish, is translation knowledge into practice and impact change. And that is the bit that we are really missing.”
