Decisive policies needed to fulfill global decarbonisation potential of biogas
The biogas industry could reduce global greenhouse gas (GHG) emissions by circa 12 percent and help governments meet their climate change commitments. The technology is mature and supports the development of a circular economy across multiple sectors but needs the political and financial will to fulfil this potential says the World Biogas Association (WBA).
Following on from the recent publication of its Global Potential of Biogas report, which demonstrates that biogas could rapidly reduce world greenhouse gas (GHG) emissions by a massive 12 percent, the World Biogas Association (WBA) has issued recommendations to world governments, financial institutions and other key decision-makers to support the industry becoming a key player in meeting Paris Agreement commitments and developing a low carbon circular economy.
Need to invest in AD
At the heart of WBA’s call is the need to move away from fossil fuel and invest in the infrastructure and incentives required to build a powerful anaerobic digestion (AD) and biogas industry that will provide not only a stable and flexible source of clean energy, but also bio-fertilisers for agriculture and a potent waste management and sanitation solution.
WBA, in fact, adheres to the call issued by the United Nations Environment Programme (UNEP) to measure and eliminate fossil fuels subsidies. These are currently about 3 to 4 times the direct subsidies given to renewable energy.
Our industry, in particular, offers greater benefits towards the development of a sustainable circular economy, turning harmful organic wastes into green electricity, gas and transport fuel, and also into a zero-carbon fertilizer that restores the soil and boosts crop yields; it brings economic growth through employment and cost-savings and promotes health and well-being through better living conditions. The technology is mature, but we are currently processing only 2 percent of the feedstock available globally. All we need to unleash this huge potential is the political and financial will to build the policy, regulatory and operational infrastructure that we need, but time is running out, said Newman.
The key recommendations focus around:
- National pledges to reduce GHG emissions, including the removal of fossil fuel subsidies, through their Paris Agreement Nationally Determined Commitments, energy plans, net-zero targets by 2050 and increases in renewable energy production and consumption over the next decade.
- The inclusion of AD into these pledges and at the core of circular economy strategies, with targets set for the production of biogas, AD included in all incentive policies and AD nominated as the preferred method of treatment for all biodegradable wastes.
- Policies to increase biodegradable wastes capture, including the provision by local governments of separate food waste collections in both urban centers and rural areas, and mandatory food waste collection and treatment for businesses of a certain size, combined with increased AD capacity to process the new waste stream.
- The development of a robust infrastructure to enable the collection and processing of feedstock in large communities as well as remote rural areas, its treatment through both large and small scale facilities, and distribution through a network of refueling points for biomethane as a transport fuel and injection points for gas going into the grid.
- The management of digestate and implementation of regulations and standards for its safe trading and use.
- Measures to ensure land is managed with due diligence to environmental impact and energy crops are integrated into production in the most sustainable way.
The Global Potential of Biogas report also lists examples of policies and schemes implemented around the world which have already made a significant difference for those countries.
The WBA’s recommendations were echoed by the Head of Global Climate Action, UN Climate Change (UNFCCC Secretariat), Niclas Svenningsen, in a keynote address during the inaugural World Biogas Summit held on July 3, 2019, in Birmingham, UK.
