Britain Cut Down Its Forests. It's Time to Build Them Back

Britain’s Timber Problem
Britain is one of the least forested countries in Europe. Woodland covers around 14% of UK land area, compared with substantially higher levels across much of the continent.[1,2] And the UK imports roughly 70-80% of its timber and wood products[3]. That's remarkable for a country with growing conditions well suited to productive commercial forestry, particularly high-quality softwood production. But this wasn't always the case.
Thousands of years of farming, settlement, industry, and infrastructure development dramatically reduced Britain’s tree cover. By the early twentieth century, woodland had fallen to a historic low of around 5-6%, making the country one of the most heavily deforested in Europe.[4] The consequences became impossible to ignore during the First World War, when Britain came close to exhausting its strategic timber reserves. Largely in response to these wartime shortages, the Forestry Commission was established in 1919 to rebuild Britain’s forestry capacity.[5]
A century later, woodland cover has recovered only partially. Today it stands at around 14% overall, approximately 10% in England, 15% in Wales, and 19% in Scotland.[1] Yet the opportunity ahead remains enormous.
Forestry Commission mapping has identified approximately 2.9 million hectares of land in England with potential suitability for woodland creation.[6] Scotland has identified around 2.96 million hectares suitable in principle.[7] Wales has also set ambitious woodland-expansion targets, though planting rates remain below what is needed to achieve them.[8] Across Great Britain, a significant proportion of this land could support carefully planned woodland expansion without compromising the most productive farmland or the highest-value habitats.
Wood as a Climate Solution
Few materials used in the built environment match timber’s climate credentials. Trees absorb carbon dioxide as they grow, storing it in wood, roots, and surrounding soils. When timber is harvested and used in construction, much of that carbon remains locked within buildings for decades, and sometimes centuries.
In sustainably managed forests, regeneration ensures that a new crop begins growing almost immediately after harvest. Meanwhile, timber used in buildings continues storing carbon, and when it substitutes for steel or concrete, additional emissions may also be avoided. For new woodland established on currently unforested land, the climate case can be particularly compelling.[9]
The construction sector accounts for a substantial share of global greenhouse-gas emissions.[10] Replacing steel and concrete with engineered timber products such as cross-laminated timber (CLT) and glulam can substantially reduce embodied carbon, commonly by around 20-60%, depending on building type and methodology.[11] For a country building hundreds of thousands of homes each year, even reductions at the lower end of that range are significant.
Not all woodland creation delivers the same benefits though. Britain contains internationally important peatlands, species-rich grasslands, and open habitats that should not automatically be planted with trees.[12] The objective is not simply to maximise tree cover, but to create the right forests in the right places.
Realising this potential would also require expanded domestic processing capacity, long-term forestry planning, and investment in engineered timber manufacturing. Growing more timber alone is not enough, Britain must also rebuild the industrial capability to use it effectively.
Does Timber Housing Last?
One of the biggest misconceptions about timber construction is that wooden buildings are temporary, but historical evidence suggests otherwise. Medieval barns, churches, and townhouses remain in active use today. Westminster Hall’s hammer-beam roof, for example, has stood for more than six centuries.
Modern engineered timber, including CLT panels, glulam beams, and Structural Insulated Panels (SIPs), is more predictable and durable than traditional sawn timber. Modern timber-frame homes are capable of achieving service lives of a century or more when properly designed and maintained.[13] The principal threats are moisture, poor detailing, and neglect, not time itself. And contemporary construction addresses these risks through vapour-control membranes, ventilated cavities, factory-dried timber, and effective drainage design.
Timber housing is not an experimental niche. Around 90% of detached homes in Sweden are timber-framed[14], while more than 90% of new single-family homes in the United States use wood-frame construction.[15] Scotland already demonstrates what widespread adoption can look like closer to home, as around 80% of new Scottish homes are built using timber-frame systems.[17]
Fire safety is also often misunderstood. Properly designed mass-timber assemblies can achieve demanding fire-resistance ratings of 60, 90, or 120 minutes.[16] Products such as CLT develop a protective char layer when exposed to fire, slowing heat penetration into the structure beneath.
Growing More British Timber
Greater domestic timber production would reduce Britain’s vulnerability to global supply-chain disruption. Forestry and timber processing also support skilled rural employment across sawmilling, haulage, nursery production, woodland management, and manufacturing.
Agroforestry (integrating trees with crops and livestock) can further improve farm resilience, soil quality, and biodiversity without necessarily displacing agricultural production.[18] And any serious discussion of woodland expansion must acknowledge wildfire risk.
Climate change is expected to increase the frequency of conditions conducive to wildfire in parts of the UK.[19] However, mixed woodlands, strategic firebreaks, fuel management, resilient species selection, and integrated wetland design can all help reduce that risk.[20]The answer is not to stop planting trees, but to plant the right trees, in the right places, in the right way.
Conclusion: Plant, Build, Sequester
The logic is compelling. Britain expands woodland cover in suitable locations. Those forests absorb carbon, support wildlife, strengthen rural economies, and provide sustainable timber. That timber is then used to construct the homes and buildings the country needs, with lower embodied carbon than many conventional alternatives. Carbon remains stored in long-lived wood products for decades or centuries, while new forests continue growing to replace what was harvested.
Versions of this model already operate successfully in countries including Sweden, Finland, Austria, Canada, Norway, and Japan. Britain possesses the growing conditions, engineering expertise, and land capability to do far more than it currently does. But realising that opportunity will require thoughtful planning, long-term investment, and a willingness to think beyond short political timescales.
Organisations like Green Up Britain are helping champion practical action through woodland creation, habitat restoration, sustainable land management, and environmental stewardship. The challenge is not simply to plant more trees or build more homes. It's to do both in a way that leaves future generations with a more resilient, biodiverse, and self-reliant country than the one we inherited.
It is time for Britain to grow the materials it builds with.
