ENVIRO-LOGS are great for times when dry wood is scarce. Made from 100 percent recycled waxed-cardboard produce crates, these logs burn for about two hours, putting out a decent amount of heat while emitting 80 percent less carbon dioxide than wood does. For a fast-starting, even-burning fire, try two Enviro-Logs at a time, using their wrappers as kindling. $21 for a case of 6, enviro-log.net
