In 2009, China led the world with over 1.4 million solar thermal cookers. India has developed solar thermal institutional systems which cook for thousands of people.
The Clean Development Mechanism (CDM) has registered eight solar cooker projects in China since 2009. A total of 207,000 parabolic cookers have been distributed, serving 848,000 people. CDM has already issued Certified Emission Reduction (CER) credits for two of these projects. The other six are too recent to be receiving credits yet.
