A new influential report has outlined the future importance of bioenergy in meeting energy needs, and in the mitigation, and even reduction of greenhouse gases. Climate Change 2014: Mitigation of Climate Change compiles scientific knowledge concerning the limitation of greenhouse gas emissions which are fuelling climate change.
In the report bioenergy is noted as having the potential to play a critical role in the mitigation of emissions, so long as care is taken to ensure that practices are performed sustainable and efficiently. In particular, crops such as Miscanththus, fast slow growing trees, and sustainably used biomass residues can reduce greenhouse gases in certain sites.
The report also poses the prospect of using of bioenergy in combination with carbon dioxide capture and storage (BECCS). It is said that this technology, if developmental challenges are overcome, may offer a solution to reduce emissions from the atmosphere on a large scale.
In predicted future climate change scenarios, preventing atmospheric concentrations of CO2eq from exceeding 450ppm, and average temperature change below 2ºC, will require a three to four fold increase in the proportion of zero- and low-carbon energy supply by 2050.
The increased use and development of the bioenergy market may also have an impact on the economic ability to mitigate greenhouse gas emissions. Models were unable to restrain CO2eq levels to below 450ppm by 2100 if either additional mitigation measures are delayed considerably or if there is an inadequate availability of technologies including bioenergy, and BECCS.
The report by the Intergovernmental Panel on Climate Change, the product of a collaboration of hundreds of scientists over four years, also tackles polices which aim to address emissions, and provide synopsis document Summary for Policymakers http://report.mitigation2014.org/spm/ipcc_wg3_ar5_summary-for-policymakers_approved.pdf
