Expectations on biochar as a climate solution in Sweden: Carbon dioxide removal with environmental co-benefits

Abstract

While carbon dioxide removal is indispensable in net-zero climate policy, incentives to deploy removals are limited. Swedish public support to biochar is one exception. This paper draws on the Swedish case to explore expectations put on biochar and the significance of public support for fulfilling these expectations. The analysis shows that biochar is expected to contribute to several environmental objectives. However, while biochar producers and users voice expectations on strengthening the multifunctionality of landscapes, e.g., improved ecosystem resilience and reduced nutrient run-off, the authorities rather narrowly direct attention to the stability of biochar as a carbon storage. Nevertheless, public support is contributing to a small but important protective space for biochar development through three channels: First, through investment grants, which are crucial for the emerging Swedish biochar production capacity. Second, through demand-pull created by municipalities that specify high environmental safeguards, which favours domestic production over import. Third, indirectly through support of production facilities that enable intermediary activities for gathering and sharing knowledge. However, while recent changes to EU state aid regulation may be a game-changer, EU has until now acted as a barrier to support to carbon dioxide removal. This socio-technical regime resistance, combined with a lack of jointly articulated expectations on biochar, appear to have been preventing deployment on more significant scale.
