Energy for All

Access to energy in emerging countries is still limited, even though it is the heart of economic growth. Our basic necessity may be someone else’s luxury. 1.3 billion people lack access to electricity, while another 1 billion have unreliable access.(1).

84% of the people with limited access to electricity live in rural areas, where GREE’s projects are located. By providing a clean and more reliable, year-round power supply, 24 hours a day and 7 days a week, GREE helps change lives. With access to reliable electricity, children can study longer hours, clinics can serve the community better, commuting after dusk is safer and small businesses can generate greater income. Generating clean and reliable energy for all is in line with SDG 7, specifically increasing reliance on clean fuels and technology and expanding infrastructure for sustainable energy services in developing countries.

Clean Water

Each food factory generates hundreds of cubic meters every day, which requires proper treatment before being released back into the environment.

GREE’s processes contribute to cleaning the wastewater to reduce the pollutant load to a level nature can handle. GREE’s technology allows the removal of 85% of organic pollutant load (the Biological Organic Demand or BOD) from the waste stream. 

The Hamparan project treats the wastewater of a food factory producing tapioca flour. The 686,124 m3 of wastewater produced each year contain as much organic pollution as the domestic sewage created by 449,922 people. Cleaning up industrial wastewater to reduce pollutant is in line with SDG 6 and 12, specifically treatment of wastewater and hazardous waste.

Climate Change

The Earth reached a CO2 atmospheric concentration of 410 ppm in 2018, a record for the past 3 million years(1). Businesses should take into account environmental and social impacts in decision-making and their business activities. A good business model generates profit, but a great business model generates profit and impact.

GREE’s projects significantly reduce methane emissions released from traditional wastewater treatment practices in Southeast Asia and replace fossil fuels with renewable energy. Hamparan project is expected to mitigate greenhouse gas emissions by 65,236 tonnes of CO2 equivalent per year, comparable to the amount emitted each year by 35,844 Indonesian people. Combating climate change is in line with SDG 9 and 13, specifically reducing CO2 emissions.

More Impacts

GREE is committed to creating a business that provides solutions to social and environmental problems. Through our biogas-to-energy projects, we provide meaningful and positive change to the society and environment, but we want to do more to magnify our impact. For example, we are studying the feasibility of producing fertilizer from the sludge of our biogas facilities to improve the livelihood of smallholder farmers in the area, we are constructing green buildings in our facilities as our commitment to go beyond the environmental standards, we are planning solar panel installation to improve energy efficiency in our biogas facilities and we discuss with local universities to spread our social and environmental innovations at a larger scale. With our dedicated in-house impact management staff, we keep on challenging our way of conducting business to create maximum positive impacts.


The impacts of Gree’s biogas-to-energy projects include energy for all, clean water, and climate action. These are in line with the Sustainable Development Goals (SDGs) - the globally shared blueprint for the future and an urgent call for action. By turning waste into valuable energy, we contribute to SDG 7 by increasing access to renewable energy for all. By cleaning wastewater, we contribute to SDG 6 and SDG 12 on water treatment. The installation of biogas facilities drastically reduces emission, which is our contribution to SDG 9 and SDG 13. To maximise our active contribution, we also partner with public and private sectors, which is contributing to SDG 17. Additionally, the creation of biogas facilities result in improvement of access of energy through reliable electricity which can indirectly impact on job creation and reducing poverty on a local level, a contribution to SDG 1 and SDG 8.

This allows us to magnify the scale of grants and create investments that generate not only economic return but also massive social and environmental impact.

Note: Our impact data are estimates based on at least 5 years of historic data from food factory. With the help of regional PT PLN, we have compiled data related to energy for all impact. Additionally, to verify our findings we held a stakeholder discussion and interview the local communities. Actual data will be updated upon Commercial Operation Date (COD) of biogas-to-energy plant
