Environmental Impacts: Composting and the Reduction of Greenhouse Gas Emissions


Indoor greenhouse

The urgent global call to mitigate climate change propels the exploration of sustainable waste management practices like composting. Learn about the environmental merits of composting and its capacity to reduce greenhouse gas emissions.


Diverting Organic Waste from Landfills

Composting diverts organic waste from landfills, making a significant dent in methane emissions, a potent greenhouse gas. Composting's aerobic process is a sharp contrast to landfilling's anaerobic decomposition, which produces more methane. Though composting requires energy, the benefits outweigh the costs. The greenhouse gas savings from diverting waste from landfills outweigh the energy usage. Using renewable energy sources further minimizes the environmental impact.

Reducing Food Waste and Saving Our Soil

The composting of food scraps minimizes greenhouse gas emissions substantially compared to landfilling, presenting a viable solution to the global food waste dilemma​. Composting augments soil health, conserves water, and reduces chemical inputs, underscoring its holistic environmental advantages. These benefits collectively contribute to a lower greenhouse gas emission footprint​.

The Energy Dynamics of Composting

Although composting requires energy, the associated greenhouse gas cost is overshadowed by the methane avoidance credits from landfill diversion. Utilizing renewable energy sources further mitigates these energy costs, demonstrating composting's potential in reducing greenhouse gas emissions​.


Policy and Regulation

International frameworks like the Kyoto Protocol endorse composting as a greenhouse gas conserving practice. The development of greenhouse gas accounting systems for composting projects is a progressive step towards promoting sustainable composting practices​.


Composting is a pivotal practice in the broader strategy to combat climate change, offering a substantial reduction in greenhouse gas emissions. Its adoption and effective management are instrumental in fostering a sustainable and eco-responsible waste management paradigm.


Let's Go Compost is a 501(c)(3) non-profit dedicated to making composting free and accessible throughout the United States. Our mission is to revolutionize waste management, reduce landfill waste, and combat harmful greenhouse gas emissions. By providing free compost bins, a STEAM (science, technology, engineering, art, and math) classroom composting program, advocating for policy change, and funding underserved communities, we ensure composting reaches all, irrespective of location or income.
