The offset model purports that forest loss in one place can be mitigated by planting elsewhere – take the political promises of ‘no net biodiversity loss’ for HS2, the high-speed mega-construction set to slice through the countryside.
But clearing vast areas of old pasture or ancient woodland would take 500 years to replace. Trees are slow, ancient, careful creatures that cannot be easily coerced into an anthropocentric regime that values quick, blueprint solutions.
Plantations are worlds away from ancient woodlands. Worryingly, by paying for carbon offsets in the form of new plantations, consumers and businesses are given the false impression of having no negative effect on the planet. What we should be focussing most of our attention on is protecting the ancient forests that exist, not planting trillions more trees.
Whilst the urgency of tree-planting for climate change mitigation is very real, our conception of what a forest is matters. Visions translate into material outcomes, and if we’re not careful, we’ll end up with a world blanketed in rows of short-rotation monocrops, poor in biodiversity, ironically justified under the banner of environmentalism.
