The Global Methane Pledge has given renewed purpose to the global biogas industry, while the current energy, fertiliser and CO2 crises have both fuelled demand for biogas/biomethane, digestate and bio-CO2 from AD, and made the case for AD common sense.

C-Zero Markets are exhibiting at the World Biogas show to engage with both producers and suppliers in this exciting and happening market to discuss the options available to them.

Tackling methane emissions caused by human activity is the most ‘immediate and cost-effective’ way to deliver the Paris Agreement target to keep global warming below 2C, ideally 1.5C. That is the conclusion of an in-depth report from the United Nations Environment Programme and Climate and Clean Air Coalition (To Reduce Short-Lived Climate Pollutants), released in May 2021.

The Global Methane Assessment report says with readily available technologies – including anaerobic digestion and biogas – immediate results can be delivered; “the majority of these major abatement potentials can be achieved at low cost, especially in the waste sector”.

Subsequently, at COP26 the EU and US jointly launched the Global Methane Pledge (GMP). To date 112 countries have signed the pledge – committing to reduce global methane emissions by at least 30% from 2020 levels by 2030, which could eliminate over 0.2C warming by 2050. 0.2C might seem a small number but in the context of climate change it is enormous – the equivalent of taking all trucks, cars and shipping Net Zero says John Kerry, former US VP and now the US Special Presidential Envoy for Climate.

The principal sources of anthropogenic methane are agriculture (40%), waste management (landfill and wastewater treatment) (20%) and fossil fuels (processing and distribution) (23%) (UNEP). The case for reducing methane through the recycling of organic wastes through AD is evident, and yet today just 2% of the 105 billion tonnes of organic wastes produced by human activity every year globally are treated and recycled – which means that 98% are still emitting methane.

Ushering in a new era of waste management presents a huge opportunity for our industry and global efforts to stabilise the climate.
