日本語
英国の代表サンプル1033人を対象に仮想評価法（二項選択形式）を用い、CCS導入への支払意思額（WTP）を推計した。平均WTPは約96ポンドで、気候変動とエネルギー安全保障への懸念が支持を支えている。政治的動機づけ推論の証拠は限定的だったが、環境フレームは経済フレームよりWTPを高めた。
English
A contingent valuation survey of 1,033 UK respondents estimated willingness to pay (WTP) for CCS implementation at approximately £96. Support was driven by climate change and energy security concerns. Evidence of motivated reasoning was found but not in a political context; environmental framing outperformed economic framing in raising WTP.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCCSはGX推進法・JCM・CCS事業化支援の文脈で政策的重要性が高いが、社会受容性や地域合意形成に関する実証研究は限られる。本論文のWTP推計手法とフレーミング効果の知見は、日本でのCCS事業における住民説明・合意形成や政策設計に示唆を与える。
In the global GX context
As governments worldwide scale up CCS as a decarbonization lever, understanding public WTP and the framing effects on support is critical for policy legitimacy. This UK study offers a replicable contingent valuation methodology and evidence that environmental framing strengthens support, relevant to CCS deployment debates globally.

📄 Abstract（原文）
The aim of this research is to investigate public preferences and willingness to pay for carbon capture and storage in the United Kingdom. In addition, this thesis seeks to understand the cognitive processes shaping opinion formation on carbon capture and storage, and the extent to which these influence willingness to pay. The first of these processes to be explored is political motivated reasoning. Previous studies have found evidence suggesting that an individual’s perceptions surrounding climate policy is influenced by political beliefs; yet, these have rarely been explored in stated preference studies. I then go on to examine another cognitive process that has been suggested to moderate the intention-behaviour gap often observed in behaviour change studies, anticipated regret.I develop a contingent valuation survey to elicit willingness to pay from a representative sample of the UK population involving 1033 individuals. The contingent valuation study employs the double bounded dichotomous choice format and interval regression models are used to estimate WTP values and determine the factors underlying these decisions. I employ split sampling to investigate the effect of different message framings on the WTP decisions made by political partisans to determine if motivated reasoning is present. Respondents are also split into treatment groups to determine if invoking the concept of anticipated regret increases willingness to pay for CCS implementation.Mean WTP for the implementation of CCS is approximately £96. Evidence of motivated reasoning is found, albeit not in a political context.In terms of the effect of invoking feelings of anticipated regret, the environmental message frame is stronger than the economic frame.The willingness to pay expressed in this study, driven by concerns about climate change and energy security, shows that the support expressed by the government for the implementation of the technology is justified by people’s preferences. Thesis is embargoed until 31 July 2028.
