Trading in China’s national carbon emissions allowance (CEA) market during the second quarter was marked by a continued slump in prices over the first two months, followed by a rebound in June accompanied by rising volumes.

From its all-time high of 105.66 yuan ($14.79) per ton on Nov. 13, 2024, the daily closing price fell 36% to a low of 67.51 yuan on June 3, marking the steepest decline in the CEA market’s four-year history. The 30-week near-continuous slide in weekly closing prices set a record for the longest losing streak.
