The “more natural” the higher the acceptance of a CCS method such as biochar production.
A cross-disciplinary collaboration at Cornell University found that a majority of the U.S. public is supportive of soil carbon storage as a climate change mitigation strategy, particularly when that and similar approaches are seen as “natural” strategies.
The team analyzed results from a survey of 1,222 U.S. adults who reported believing in climate change at least “somewhat,” to estimate public support for soil carbon storage and how it compares to other leading carbon dioxide removal strategies. It solicited respondents’ perceptions of naturalness and policy support for five CO2 removal strategies: afforestation and reforestation; bioenergy plus carbon capture and storage; direct air capture; soil carbon storage; and soil carbon storage with biochar.
In the final analysis, perceived naturalness was a strong indicator of support for soil carbon storage as a climate change mitigation strategy. Of the five CO2 removal strategies, support was highest (73%) for afforestation and reforestation; soil carbon storage ranked second, supported by 62% of those polled.
