Concrete is a very common material used in backyard chicken coops. While concrete offers durability and strength, its use in chicken coop construction has several environmental consequences. Here is a closer look at the various environmental impacts of using concrete in chicken coops. Greenhouse Gas Emissions Cement production accounts for about 8% of global CO2 emissions . Using concrete for chicken coops contributes to this. Producing just one cubic yard of concrete emits over 200 lbs of CO2 . A typical 8 x 8 ft chicken coop foundation can use 2-4 cubic yards of concrete. This means a single backyard chicken coop can be responsible for 500-800 lbs of CO2 emissions just from the concrete alone. Energy Consumption Concrete production requires immense amounts of energy for cement manufacturing and transportation. The energy used to produce concrete for chicken coops depends on: Cement manufacturing process (wet vs dry) Transportation distance of cement Mixing methods...
