An Analysis of Carbon-Reduction Pledges of U.S. Oil and Gas Companies
研究了69家美国上市油气公司的碳减排承诺，发现黑石持股和能源产量与承诺正相关，市场对净零承诺反应更负面，且负面反应与承诺质量（目标年份、董事会监督、高管薪酬挂钩）相关。
We study carbon-reduction pledges of publicly traded U.S. oil exploration and production (E&P) companies. Of the 69 firms in the sample, 18 have committed to net-zero carbon targets, 14 have announced significant emissions cuts, whereas the remaining 37 firms have not announced any formal commitment to reduce emissions. We find that a firm’s energy production and ownership by BlackRock is positively associated with its decision to announce a net-zero pledge or significant emission cuts. E&P firms are likely to announce such commitments after Engine No. 1 proposed its slate of directors for Exxon’s board. The stock market reacts more negatively to net-zero pledges relative to emission-reduction pledges on average. However, the market reaction is related to the quality and credibility of these pledges. In particular, we find that the negative market reaction to net-zero pledges is mainly driven by firms with post-2030 target years relative to firms that commit to achieving net zero by 2030. We also find that the market reacts more negatively to net-zero pledges when the firm does not show the strength of its commitment via the presence of a board-level committee to monitor the company’s progress toward its emission goals or when the top management’s pay is not linked to specific emission reduction goals.
