本論文はMESSAGEix-Buildingsモデルを拡張し、炭素価格とグリーンファイナンスが建築部門の脱炭素を共同で促進する可能性を定量化。北京の民生建築をケーススタディとし、4つのシナリオを分析。炭素価格単独で11.44%の排出削減、両政策の併用で最終エネルギー消費4.68%削減、総投資5.27%節約を達成。価格制約と金銭的インセンティブの補完メカニズムを解明。
English
This paper extends the MESSAGEix-Buildings model to quantify the potential of carbon pricing and green finance jointly driving deep decarbonization in buildings. Using civil buildings in Beijing as cases, it finds carbon pricing alone reduces emissions by 11.44% by 2050, while joint implementation yields additional 4.68% reduction in final energy consumption and 5.27% savings in total investment, revealing complementary mechanisms of price constraints and financial incentives.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもカーボンプライシングとグリーンファイナンスの政策連携が議論されている。本論文は建築部門における両政策の補完効果を定量化する手法を提供し、東京都等の大都市での脱炭素政策設計に示唆を与える。
In the global GX context
As Japan explores carbon pricing and green finance, this paper provides a quantitative framework for assessing their synergy in building decarbonization. The Beijing case offers insights applicable to megacities globally, and the endogenous policy approach is valuable for integrated policy design.
👥 読者別の含意
🔬研究者:Researchers can adopt the extended MESSAGEix-Buildings model and endogenous policy approach for similar policy-mix analyses in other sectors or regions.
🏢実務担当者:Building sector stakeholders can use the quantitative evidence to advocate for combined carbon pricing and green finance policies that reduce energy consumption and investment costs.
🏛政策担当者:Policymakers can leverage the scenario results to design and calibrate carbon pricing and green finance instruments for deep decarbonization in the building sector.
📄 Abstract（原文）
To quantify the potential of carbon pricing and green finance to jointly drive deep decarbonization in the building sector, this paper extends the MESSAGEix-Buildings model using a policy-endogenous approach. It incorporates the internalization of carbon pricing and carbon emission costs, as well as mechanisms to relax capital constraints in green finance, into the system optimization framework, thereby enabling the quantification of marginal abatement costs and policy interactions. Using civil buildings in Beijing as case studies, four scenarios were devised for simulation analysis. The results show that: (1) carbon pricing alone can achieve a 11.44% reduction in carbon emissions by 2050, whereas green finance can only alleviate investment barriers and deliver only modest additional emission reductions; (2) when the two policies are implemented in tandem, the joint framework generates complementary price constraints and financial incentives, achieving an additional 4.68% reduction in final energy consumption and a nearly 5.27% saving in total investment compared with the carbon-pricing-only scenario. The study elucidates the complementary mechanism of ‘price constraints and cost incentives’, highlighting the methodological value of an endogenous policy approach, and provides quantitative support for the implementation of carbon neutrality in construction and green finance in megacities.
