What sort of business these days would buy a whole forest's worth of carbon-trapping trees when no law says they must?

They're the eco-conscious ones - like Kwikfit, The Green Insurance Company, Marks and Spencer, Stagecoach and others - all happy to pay good money to restore native woodland to bare British hills. And it's not just because trees trap carbon dioxide. They also love the fact that their forest will eat dust and pollutants, give succour to our native flora and fauna, and make picnics and walks for future generations of humans.

Our clients' carbon management plans focus first and foremost on emissions avoidance. Aware that a new woodland captures carbon too slowly to swallow all their own current emissions, they plant for an ongoingly healthy environment. Unlike many of our other desperate 'green' remedies (which must be made in factories or anchored with concrete) trees cause no collateral damage.

The UN inter-governmental Panel on Climate Change admits that, despite the best efforts of science and technology, the rate of global warming won't even begin to slow before 2050. Whilst sea levels rise and rain forests shrink we frantically do our best: we save energy, manage waste, write green laws, design cleaner engines, harness sun, wind and sea, fine polluters and argue about what does and doesn't work. In the meantime we can be helping Nature to help herself - by restoring the trees we chopped down over the centuries for our wars and commerce and other needs.

This planet needs all the help it can get, and all the tree-life it can get, too. When our clients buy a whole woodland's worth of natural air-cleaners (that'll outlive the lot of us) they're doing it because they respect the work of trees, because they can and because they care.
