Fertilizer is one of the most emissions-intensive aspects of farming. Fortunately, there is a new way to produce ammonia, the key ingredient in fertilizer, without the high heat and intense pressure that gives conventional fertilizer its huge footprint. This air-zapping laser process has been shown to produce almost 40 times more ammonia compared to the currently used process, at a sliver of the energy cost. Production can be decentralized to farms since the vast infrastructure that conventional fertilizer production requires isn’t needed. That cuts out another source of emissions from the transport typically required to ferry fertilizer across the globe.
