Socio-political prioritization of bioenergy with carbon capture and storage

Limiting global warming to well below 2 degrees C requires the transformation of the global energy system at a scale unprecedented since the industrial revolution. To meet this 2 degrees C goal, 87% of integrated assessment models opt for using bioenergy with carbon capture and storage (BECCS). Without BECCS, the models predict that the goal will be either unachievable or substantially more costly to meet. While the modeling literature is extensive, studies of how key climate policy actors perceive and prioritize BECCS are sparse. This article provides a unique intercontinental mapping of the prioritization of BECCS for the long term transition of the electricity supply sector. Based on survey responses from 711 UN climate change conference delegates, the article reports the low prioritization of BECCS relative to alternative technologies, indicating an urgent need for studies of the sociopolitical preconditions for large-scale BECCS deployment.
