日本語
ニューヨーク市のLocal Law 97を事例に、規制の承認時と執行開始時における米国REITの株価反応をイベントスタディで分析。承認時は有意な異常リターンが見られなかった一方、執行開始時はNYオフィス比率の高いREITを中心に経済的に意味のある負の異常リターンが観察されたが統計的有意性は乏しい。移行リスクは短期的には軽微で、執行接近に伴い徐々に価格に織り込まれる可能性を示唆する。
English
Using NYC's Local Law 97 as a case, this event study examines how U.S. REITs with NYC exposure respond to building decarbonization regulation. The 2019 approval produced insignificant abnormal returns, while the 2024 enforcement onset coincided with economically meaningful but statistically insignificant negative returns, concentrated in office-heavy REITs. Findings suggest transition risk is priced gradually and becomes more salient as implementation approaches.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも省エネ規制強化やSSBJ開示が進む中、規制の「執行フェーズ」が資産価格に与える影響を段階的に織り込む視点は、不動産・建設セクターの移行リスク管理や投資家対応に示唆を与える。
In the global GX context
As ISSB/CSRD push building-sector transition disclosure, this paper offers rare capital-market evidence on how binding emissions caps (LL97) get priced—relevant to TCFD transition-risk assessment and real estate transition finance globally.

📄 Abstract（原文）
Climate transition risk is emerging as a critical determinant of value in real estate finance as cities adopt increasingly stringent decarbonization policies, adding to the pressure of physical risk. Regulations impacting the construction sector, which represents 40% of global carbon emissions, have the potential to impact energy and commodities markets. New York City's Local Law 97 (LL97), which imposes binding emissions caps and financial penalties on large buildings, offers a case to examine how capital markets respond to building-sector climate regulation. This paper investigates whether and how U.S. equity Real Estate Investment Trusts (REITs) with exposure to New York City assets respond to climate transition policies like LL97. Using a standard event study framework, the analysis examines abnormal returns around two key milestones: the policy's approval as part of the Climate Mobilization Act in April 2019 and the onset of its enforcement phase in January 2024. Results show that the initial announcement generated statistically insignificant cumulative abnormal returns, suggesting that investors did not price LL97's long-term horizon implications at the time of the vote. By contrast, the enforcement milestone coincided with economically meaningful negative abnormal returns across most sampled REITs, particularly those with substantial New York City office exposure, although these effects are not statistically significant and can be attributed to broader sectoral stress. Cross-sectional tests reveal no significant differences between highly and moderately exposed groups. Overall, while isolating the impact of transition risk alone is empirically challenging, the findings suggest that climate-related transition risk is priced gradually, potentially non-material in the short term and can become more salient as implementation approaches.
