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

Area of Science:

• Environmental Science
• Climate Change Mitigation
• Public Perception Studies

Background:

• Biological carbon removal (BCR) is promoted for climate and sustainability benefits.
• Public perception research lacks explicit evidence on BCR trade-offs.
• Understanding public views is crucial for effective climate policy.

Purpose of the Study:

• To explore UK public perceptions of BCR options and their associated trade-offs.
• To investigate public skepticism towards emissions reductions and behavior change.
• To identify regional differences in public discourse on climate action.

Main Methods:

• Small group deliberations (n=60) and a nationally representative UK survey (n=2027).
• Exploration of perceptions across the UK's four jurisdictions.
• Analysis of public views on specific BCR techniques (biochar, peatland restoration, biomass crops).

Main Results:

• Strong public preference for BCR to meet national climate targets, driven by skepticism about emissions reductions.
• Public caution regarding the "worth" of specific BCR techniques due to concerns about life-cycle emissions, land competition, and scientific uncertainty.
• Evidence that BCR discussions can shift responsibility for climate action away from individuals.
• Identification of region-specific discourses influencing public views.

Conclusions:

• Public support for BCR is significant but conditional on addressing concerns about specific methods and their impacts.
• Local context and regional discourses play a vital role in shaping public acceptance of climate mitigation strategies.
• Further research is needed to address scientific uncertainties and land-use conflicts associated with novel BCR techniques.
