| Bioplastics | Land Sinks | Most plastics are made from fossil fuels, but bioplastics utilize plants as an alternative source of carbon. They often have lower emissions and sometimes biodegrade. | Details |
| Recycled Metals | Land Sinks | Metals are extracted from nonrenewable ores. Recycled metals capitalize on already extracted materials—making it possible to produce goods more efficiently, reduce the need to extract new resources, and cut down on energy and water use. | Details |
| Alternative Cement | Land Sinks | Conventional cement production is a significant source of carbon dioxide. Reformulation can reduce emissions by millions of metric tons each year. | Details |
| Composting | Land Sinks | Composting can range from backyard bins to industrial-scale operations. Regardless, it converts organic waste into soil carbon, averting landfill methane emissions in the process. | Details |
