Tesco has opened what it claims is Asia's first 'zero carbon' hypermarket in Thailand, as part of its plans to be a "zero carbon business" by 2050.

The Bang-Pra Tesco Lotus store, which opened yesterday (1 December), features "green" technologies such as a wind turbine, lower wattage LED lighting, hydro-carbon powered fridges and "rammed earth walls", which are said to be less carbon-intensive to manufacture than concrete or steel.

The store also uses rainwater to flush its toilets, in addition to using more natural light and less electric lighting.

"We are proud to have opened the first zero carbon store in Asia," said Tesco's group climate change director, Helen Fleming. "It's particularly fitting that it has opened in Thailand, as it is home to the first Tesco Environment store, which opened in 2004."

Fleming said the firm's "energy efficient measures" have resulted in GBP200m (US$313.8m) in annual cost savings.
