Lessons from Shenzhen carbon exchange will help others flourish
Experiences of China's first carbon trading scheme over its initial four months inform preparations for exchanges in other cities

More than four months into its operation, China's first carbon emissions exchange in Shenzhen is seeing thin trading volumes and sharp price fluctuations.

The Shenzhen Emissions Exchange in June became the first of seven pilot carbon-trading schemes to go online.
It covers 635 industrial firms and 197 government buildings, which accounted for about 40 per cent of the city's total emissions in 2010.
The municipal government has given annual emission quotas to each firm. Their performance will be reviewed every 12 months and their allotments adjusted accordingly. They have a combined quota of 100 million tonnes of carbon, which covers their operations from this year to 2015.
The companies, as well as individual investors, can buy carbon credits by the tonne. The goal is to reduce pollution by offering polluters economic incentives to reduce emissions.
