"Why All Carbon Credits Are Not Equal"

"The market for voluntary carbon credits has taken off. It will grow to $2 billion in 2021, quadrupling in a year. The Boston Consulting Group, a management consulting firm, expects to be worth somewhere between $10 billion and $40 billion by 2030. Carbon credits offer companies a simple way to strengthen their ecological competence and channel much-needed finance into environmental projects, often in developing countries." (By Lara Williams
