Table 2 Simulated scenarios

From: Multiple planetary boundaries preclude biomass crops for carbon capture and storage outside of agricultural areas

Scenario name

Description

Agricultural baseline

2017 land use without expansion of biomass plantations

CDRonly

Illustrative reference scenario to maximize carbon dioxide removal by expanding biomass plantations; focus on the climate change PB alone without consideration of trade-offs with terrestrial PBs

+PB-N/+PB-W/…

Biomass plantation expansion and/or management intensification is only allowed, where the respective PB is not yet transgressed in the agricultural baseline, up to the point the regional threshold is reached (see Table 1)

allPBs

All four terrestrial PBs are considered, i.e., biomass plantation expansion and management may not lead to additional transgressions of the regional thresholds

allPBs+

As a more strict implementation of the land system change PB, all remaining (semi-)natural forests are protected from conversion to biomass plantations (FP forest protection) in addition to the three other terrestrial PBs

  1. Scenarios for testing the effect of constraining the expansion and management of biomass plantations for bioenergy with carbon capture and storage (BECCS) with terrestrial planetary boundaries (PBs) under mid-century RCP4.5 climate.
