The basis for the carbon risk premium is that studies:选项：
A.definitely show that companies with higher CO2 emissions are associated with higher returns. B.definitely show that companies with higher CO2 emissions are associated with lower returns. C.are inconclusive in establishing a definitive link between CO2 emissions and returns.解释：
C is correct. A carbon risk premium is said to exist when investors require higher compensation for the perceived risk from investing in high-carbon companies. Several studies have argued that that companies with higher (absolute levels of or relative increases in) CO2 emissions are associated with higher returns. However, studies have also found evidence for the converse—a positive link between reductions in carbon footprint and improvements returns.这是一个基础性的疑问，减排究竟是有利于增加回报的还是减少回报的？这里的意思是不确定，但是其他章节的内容又在讲减排是好的，矛盾？
