We develop certified methane-reduction projects in Indonesian agriculture, delivering high-integrity climate impact.
In Indonesia, more than 90% of food processors are not yet equipped with modern wastewater treatment and methane avoidance systems. This produces water pollution equivalent to that of 320 million people and generates methane emissions equivalent to about 50 million tonnes of CO₂e per year.
Reducing methane: a quick win to combat the climate crisis
Rapidly reducing methane emissions is one of the single most effective strategies to keep the goal of limiting warming to 1.5˚C, whilst also delivering co-benefits such as improving public health1 and agricultural productivity. Methane has a global warming potential of more than 80 times that of CO₂ over a 20-year timeframe. and accounts for 30% of global warming since pre-industrial times.
Cost-effective solutions
Methane avoidance from food industry wastewater is one of the most cost-effective solutions to reduce greenhouse gas emissions as each tonne of methane captured results in 28 carbon credits. Dependable methane avoidance solutions already exist and just need deployment now. Gree Energy uses proven and mature technologies that are also economical.
Real emission reductions with no measurement risk
Gree Energy develops high-quality biogas projects generating emission reductions that are independently verified.
Avoided methane emissions are measured in real time by flowmeters, gas analysers and state-of-the-art monitoring equipment. The trusted system safeguards data integrity, reliability and accuracy, with no risk of reversal.
Biogas from food industry wastewater is one of the select climate solutions identified by the United Nations Framework Convention on Climate Change in the positive list of technologies because of its high additionality, and it meets the highest standard of quality assurance.
Create verifiable impact.
Gree Energy is Asia's only B Corp-certified biogas solutions provider and meets the highest standards of verified social and environmental performance.
Positive impact is at the core of our organisation. We seek to create real positive change for people wanting a healthier life, economic growth, and a cleaner environment. We believe in directly impacting people’s lives through rural development, giving access to clean, reliable energy and reducing pollution. Our safeguards are in line with the world-class industry standards including VCS, IFC PS and IRIS+.
