Do feasibility-stage decarbonisation conclusions survive tariff and carbon-factor drift? A controlled current-data rebasing audit of four calibrated UK primary-school retrofit cases

日本語

英国の小学校4校の改修事例を対象に、実現可能性調査時の脱炭素効果の結論が、エネルギー料金や炭素係数の変動後も有効かを再評価した監査研究。最新データで再計算し、結論の頑健性を検証。政策や投資判断への示唆を提供。

English

This audit re-evaluates four UK primary-school retrofit cases to test whether feasibility-stage decarbonisation conclusions remain valid after changes in energy tariffs and carbon factors. Using current data, it assesses the robustness of initial findings, offering insights for policy and investment decisions.

日本のGX文脈において

日本では学校施設の脱炭素改修が進む中、初期試算の前提が変動した場合の影響を検証する手法は、自治体の投資判断や補助金評価に参考になる。ただし英国の料金・炭素係数に基づくため、日本の制度に合わせた調整が必要。

In the global GX context

Globally, this study addresses the critical issue of whether decarbonisation feasibility studies remain valid under changing energy prices and carbon factors, relevant for climate finance and policy evaluation. It provides a methodological template for auditing retrofit projects, supporting robust decision-making in line with TCFD and ISSB expectations.
