WBA report focuses on biogas potential

Posted: Wednesday 12th May 2021

“Appropriate management of all organic wastes must be enabled NOW if the world is to meet Paris Agreement targets”, says global biogas trade body in landmark report.

The World Biogas Association (WBA) has launched its latest report: Biogas: Pathways to 2030, which provides a comprehensive review of how management of unavoidable organic waste through anaerobic digestion (AD) could deliver by 2030 a 10% reduction in global greenhouse gas (GHG) emissions – and in particular methane, which is 85 times worse than carbon dioxide over a 20-year period.

Human activity generates 105bn tonnes of organic wastes (food waste, sewage and garden wastes, food and drink processing wastes, and farm and agricultural wastes) annually by human activity. By managing these properly, we can

(a) reduce the quantity produced – delivering a 3% reduction in GHG emissions- and
(b) treat the GHG-emitting balance – removing a further 5% of emissions, and then
(c) recycle this balance through AD into alternatives to fossil-based products – delivering a further 5% reduction in GHG emissions

Once all avoidable waste is prevented, the remaining unavoidable waste can be recycled into green energy for power, heat and transport as well as biofertilisers for agriculture, bio-CO2 and other valuable bio-products. However, only 2% of those wastes are currently being effectively managed.

By mapping out how AD and biogas could help countries to dramatically cut their greenhouse gas emissions, especially methane, over the next decade and beyond, this report aims to put humanity back on track to deliver on the ambitions of both the Paris Agreement and UN Sustainable Development Goals.” says David Newman, President of WBA.

The report highlights the fundamental part our industry can play in achieving net zero and in creating a circular, sustainable and environmentally-friendly economy for both high- and low- income countries. Ahead of COP26, these countries should integrate AD and biogas into their NDCs if we are to successfully address the climate emergency. And they need to do so urgently.”

Charlotte Morton, WBA Chief Executive, added: ” Current nations’ climate plans deliver a hopeless 1% of the 45% greenhouse gas emissions reductions the Intergovernmental Panel on Climate Change says is required to keep climate warming to below 2C. Treating the world’s unavoidable organic wastes through AD would help meet over one quarter of this alarming shortfall (2). We cannot afford to miss such an opportunity and need to act NOW to ensure that AD and biogas can fully play their part in addressing climate change.”

Key recommendations to biogas industry stakeholders, governments and policymakers around the world include:

· The global AD and biogas industry must come together to develop and adhere to best-in-class principles and norms associated with responsible investing (including good governance and supply chain transparency). This follows up on the Biogas Industry and Climate Change Commitment Declaration of November 2019 in which the industry pledged to put all its technical, financial and human resources towards delivering on the global GHG reductions ambition. The Declaration was presented to the UNFCCC at COP25.

· The global AD and biogas industry should actively contribute to science-based thought leadership around carbon pricing, accounting and reporting, and adopt methods that successfully monitor and verify the sustainability and environmental safety of its processes.

· Governments should include the collection and recycling of organic wastes among their target instruments when reviewing their Nationally Determined Contribution to the Paris Agreement.

· Governments should not simply measure biogas in terms of energy, but in the overall beneficial outcomes across a whole range of environmental services and wider benefits to society.

· Policymakers should facilitate the development of a market for the environmental benefits of biogas, while enabling the industry to become independent of direct subsidy. This should be accompanied by the balanced removal of all direct support for the fossil industry to ensure there is a level playing field before any subsidies for biogas are removed.

· Policymakers should introduce national, regional and finally global carbon trading mechanisms to create an effective market for the climate benefits of biogas. The scope and methodology of these mechanisms must cover GHG emissions as well as methane capture and carbon sequestration from agriculture and from organic wastes generated by human activity.
