...Michael Dell changed the way PCs are made and sold. In the past year, though, rivals have gained on him. So this year he's going for a green advantage: he wants to erase some of the environmental cost of running computers by offering a way to neutralize the carbon dioxide emitted by a PC. Dell, 41, spoke with TIME's Bryan Walsh about climate change, the media and small, shiny objects...
Treeflights.com is just one beneficiary of a growing environmental subindustry known as "carbon offsetting." Typically, one of this new breed of companies first calculates the amount of greenhouse gases an individual or business generates by flying, driving or heating and lighting a home or office. Customers then voluntarily pay that firm to invest in projects that will cut carbon emissions by an equal amount. (Energy-hungry Americans generate about 20 tons of CO2 per capita per year; Britons, about half that). So for anything between $4 and $40 to offset the equivalent of one ton of CO2, a consumer...

Voluntary carbon offsetting is an unlicensed industry, and without a common regulator to police the projects and companies pledging to shrink emissions, offset providers have come up with a raft of competing rules and practices, not all of them with the credibility customers expect...
...absorb in its lifetime. Scientists estimate that, depending on the soil and climate, a hectare of 1,000 trees can process between five and 10 tons of CO2 each year. But the longer the time span, the harder the absorption is to predict. Some companies, such as London's Carbon Clear, say they invest not just in planting trees, but also in ensuring they thrive. But others may not be so diligent and disease, fire and logging can all shorten a tree's life. "You can never be sure the atmosphere sees the benefit," says Dietrich Brockhagen, managing director...
...Michael Schlup, director of the Gold Standard Foundation in Basel, Switzerland, an organization dedicated to eradicating just such inconsistencies. His group unveiled what's designed to be a rigorous, industry-wide protocol in May, and says that around 20 projects are currently applying the code. A rival benchmark Voluntary Carbon Standard is expected to be drawn up soon by the International Emissions Trading Association and the U.K.'s Climate Group...
