Firm Commitments
研究发现，做出减排承诺的企业确实减少了自身排放，但对整体企业排放影响甚微；承诺更普遍存在于排放较低的企业，而在政府有国家承诺的国家中较少见。
A growing fraction of companies globally have made commitments to reduce their carbon emissions by a certain date. Whereas the companies that make commitments subsequently reduce their emissions, the effect on overall emissions of companies (including those that do not commit) has been small. The companies that commit and those that make the most ambitious commitments tend to have lower emissions; firm commitments are less prevalent in countries where governments have made national commitments. Overall, the commitment movements have been successful in drawing the willing but have found greater resistance from the companies that most need to reduce their emissions.
