Q:  What sort of business, these days, buys a whole forest's worth of carbon-trapping trees when no law says they must?

A:  Eco-responsible ones: Kwikfit, The Green Insurance Company, Marks and Spencer, Stagecoach, Mears Group and our other clients all continue to contribute towards the restoration of native woodland to bare British hills. It's not just because trees trap carbon dioxide. They also eat dust and pollutants, they give succour to our native flora and fauna, they tame the wind and water and they beautify the landscape.

A good carbon management plan will start with emissions avoidance but it shouldn't end there. When it comes to keeping the environment in good shape trees do a fine job and we need more of them. Unlike many of our other 'green' remedies - churned out in smoky factories or anchored with concrete - trees cause no collateral damage.

Regardless of whether climate change is 'man-made' or not: we still have to deal with the increasing pollution itself. Our global effort to preserve rainforests, save energy and cut emissions is determined and ongoing, albeit fraught with debate. But even with the best that science, politics and technology can offer it's universally accepted that it'll be 40 years before any sort of impact on global-warming can be achieved.

Meantime we can be getting on with helping Nature help herself. When our clients pay for the creation of new native woodlands to replace those lost over the centuries, they're giving us a better environment, now and far off into the future. What a wise and pleasant way to save the world.
