摘要

生物碳去除被认为是气候、可持续性和公众舆论的“双赢”,但是关于公众看法的研究缺乏关于选择之间权衡的明确证据。在这里,我们通过小组审议(n60)和全国代表性调查(n2027)在英国的四个司法管辖区探讨了人们的看法。我们发现,由于对减排和行为改变的持续怀疑,人们强烈倾向于在实现国家气候目标方面发挥重要作用。然而,由于某些生物技术——生物炭、泥炭地恢复和多年生生物质作物——是否“值得”,这种支持受到了限制。特别是,人们对生命周期排放、迫切住房需求带来的土地竞争以及生物炭等新技术的科学不确定性提出了担忧。虽然我们发现,对碳去除的回应往往会将气候行动的责任从个人身上转移,但我们也发现了特定地区的话语,强调了当地环境在塑造公众观点方面的重要性。

Carbon removal support is tempered by concerns over whether biological methods are worth it.

Carbon removal support is tempered by concerns over whether biological methods are worth it.

Biological carbon removal has been proposed as a 'win-win' for climate, sustainability and public opinion, but research on public perceptions is lacking explicit evidence on trade-offs between options. Here we explore perceptions using small group deliberation (n60) plus a nationally representative survey (n2027) in the UK's four jurisdictions. We find a strong preference for carbon removal to play a substantial role in meeting national climate targets, stemming from persistent scepticism about emissions reductions and behaviour change. However, such support was tempered with caution about whether certain biological techniques - biochar, peatland restoration, and perennial biomass crops - would be "worth it". In particular, concerns were raised about life-cycle emissions, as well as land competition with urgent housing needs, and scientific uncertainty around novel techniques such as biochar. While we find that responses to carbon removal tend to shift the burden of responsibility for climate action away from individuals, we also identify region-specific discourses, highlighting the importance of local context in shaping public views.
