Online auction site Trade Me say the sell through rate for carbon credits is 71 percent, by far the highest of any category on the site.

Christine Turner, General Counsel for Trade Me explains that “it’s partly because we don’t have a lot of listings up there so they tend to get snapped up, and the feedback I’ve had from the guys who are currently doing classifieds is that they’re actually doing a number of sales through those classifieds.”

Trade Me boasts “about 50 transactions” in carbon credits since September last year.

“The people selling them tend to be businesses that have generated credits like Meridian, or Energy Mad who did the eco-bulb campaign; or carbon brokers.”

“It’s not something that we’re making a bunch of money out of, but we think it’s a good thing to support” maintains Turner.

Trade Me currently has over 2 million active members, with over 4 million people visiting in June, spending an average of 18 minutes on the site.
