DO TREE PLANTATIONS OFFSET FOSSIL FUELS?
XYZ Corporation has purchased carbon offsets to compensate for their carbon dioxide releases. Often they will do it for you too- pay to have someone somewhere "plant a tree" or a thousand trees or a hundred thousand trees, in order to go on with business as usual. The internet abounds with web sites that will help you calculate how many trees you need to pay for in order to do penace for your carbon-intensive lifestyle - at up to $5.50 per tree. So is it really that easy? No need to conserve or make radical changes, just pay someone somewhere a hefty sum for planting a few trees? Here's what forest campaigner Jutta Kill of the European environmental group FERN thinks of the concept.
1. Carbon in trees is temporary:
Trees provide temporary carbon storage as part of the normal cycle of carbon exchange between forests and the atmosphere. Trees can easily release carbon into the atmosphere through fire, disease, climatic changes, natural decay and timber harvesting.
2. One-way road:
The release of fossil carbon, in contrast, is permanent and, over relevant time scales, will accelerate climate change by increasing the overall amount of carbon in the atmosphere - the very cause of today's climate change. Fossil fuels such as coal, oil and gas are locked away and their carbon is only released when humans dig up and burn them for energy. Once released, they become part of the active carbon pool, disrupting the natural cycle.
