The British landscape is often celebrated for its rolling hills and dramatic mountains, but beneath the surface of our moors lies a silent hero in the fight against climate change. The United Kingdom’s peatlands are among the most efficient carbon-storing ecosystems on the planet. However, we are currently facing a severe Peat Bog Crisis that threatens to turn these vital resources from carbon absorbers into carbon emitters. As environmentalists push for stricter regulations, a heated debate has emerged with burn deniers—those who continue to support the traditional practice of rotational burning on grouse moors—challenging the necessity of a total ban.
To understand the stakes, one must first recognize the sheer scale of peat as a natural asset. Although peatlands cover only about 12% of the UK’s land area, they store more carbon than all the forests in the UK, France, and Germany combined. When these bogs are healthy and waterlogged, they act as massive, ancient sponges. However, when the surface is burned or drained, the peat dries out and begins to release its stored CO2 back into the atmosphere. This is the heart of the Peat Bog Crisis. Every hectare of degraded bog contributes to the warming of our planet, making the task of protecting UK’s carbon sinks a national priority for 2026.
The group often referred to as burn deniers argues that controlled “cool” burns are necessary for land management. They claim that removing old heather prevents larger, uncontrollable wildfires and supports certain types of biodiversity. However, scientific consensus in recent years has shifted heavily against this view. Modern research suggests that even controlled burns damage the delicate sphagnum moss that is essential for the formation of new peat. By damaging this top layer, the burning prevents the bog from regenerating, exacerbating the Peat Bog Crisis. For the UK to meet its net-zero targets, the philosophy of land management must shift from exploitation to restoration.
Protecting UK’s carbon sinks requires a multi-faceted approach. Restoration involves “re-wetting” the bogs by blocking drainage ditches that were dug decades ago for agriculture or sport. When the water level returns to the surface, the peat becomes anaerobic again, stopping the oxidation of carbon. This process not only helps the climate but also improves water quality and reduces the risk of flooding in downstream communities. Despite the resistance from burn deniers, many estates are now seeing the economic potential in “carbon credits,” where landowners are paid to restore bogs rather than burn them.
