Abstract

Many global decarbonisation scenarios suggest that bioenergy with carbon capture and storage (BECCS) is an important option for CO2 emissions mitigation. Bioenergy has been well modelled in the TIAM‐UCL model, with previous work having identified the significant impact of BECCS on the projected costs of achieving a 2 °C target (McGlade et al., Unavailable). This chapter builds on this work, using TIAM‐UCL to investigate the extent to which BECCS is critical for meeting global CO2 reduction targets under different long‐term scenarios out to 2100. The chapter also assesses the potential impacts of BECCS on mitigation costs under various scenarios at a global scale. Though previous work has suggested that BECCS can play a crucial role in meeting the global climate‐change mitigation target, uncertainties remain in two main areas: the availability of biomass, which is affected by many factors including availability of land for biomass production and sustainability of bioenergy production including consequences for greenhouse gas (GHG) emissions. In order to assess the importance of these uncertainties, this chapter develops several scenarios by varying the availability of biomass (sustainability of the bioenergy production) and peaking year for GHG emissions under 2 °C and 1.5 °C climate‐change mitigation targets at a global level. Scenario analysis suggests that without BECCS, or other negative emissions technologies, the targets may simply become implausible – certainly 1.5 °C but perhaps also 2 °C.
