The blocks are 1/10 of the carbon footprint of a cement block.

Excerpt:

Henry showed up with about 100 Earth Blocks. His farm is a little over an hour away in Cobourg Ontario. He makes the blocks from his local clay, and adds 5-8% cement. The blocks are 1/10 of the carbon footprint of a cement block. They contain far less cement and are air-dried rather than kiln-dried. While they won’t last as long as cement blocks, they are comparable to wood for longevity, and using them thus leaves more trees alive and breathing. By growing more food and composting food waste close to home, greenhouse gas emissions are reduced. Further reductions are obtained by organic practices that do not use fossil fuels for fertilizer. Each bed this size will reduce GHGe by between 1.13 and 1.38T.

And the Earth Blocks look sharp, too. After the bed is built, we will coat the blocks with a low-VOC sealer and then let kids paint on the exterior. Raised beds warm up faster in spring and cool down slower in fall, adding length to the growing season. The thermal mass of the blocks moderates temperatures and protects the plants from extremes. You can add a plastic row cover under which Bloomsdale spinach will grow all winter.
