Franshion Properties (China) Ltd has signed a deal with Beijing Green Carbon Energy-conservation Technology Services Co Ltd to sell the latter 1,000 metric tons of carbon emission quotas each year.

The move marked the first carbon trading deal in China’s construction sector. And the two companies will have more cooperation in the environment friendly sector.

Franshion’s carbon emission quota mainly comes from the company’s efforts in energy saving renovation. It modified a Grade A office building in Beijing last year and saved 25 percent more energy than before, for a total of 2,000 tons of carbon emissions.

In 2010, the developer made “green building” its key strategy.

Industry statistics showed that around 40 percent of carbon emissions comes from real estate and construction sectors.
