In its April 2014 report, the Intergovernmental Panel on Climate Change (IPCC) recognized that reducing greenhouse gas (GHG) emissions by 40 to 70% by mid-century will require more than just implementing emission-free solutions. Many scenarios for stabilizing GHG concentrations that were evaluated by the panel included removing carbon dioxide (CO2) from the atmosphere: so-called “negative emissions” or carbon dioxide removal (CDR). Among the most promising CDR methods are reforestation, afforestation (planting new forests), and bioenergy with carbon capture and storage (BECCS). However, for BECCS strategies to succeed, major hurdles must be overcome.
