Coconut-based peat substitutes (such as coir pith, fiber, and chips) are playing an increasingly important role in the growing media industry. Since these products are typically imported from countries such as India and Sri Lanka, concerns are often raised about their carbon footprint. However, despite the long transport distances, the emissions per ton are significantly lower than those of trucks over the same distance, thanks to the high cargo capacity of ships. Moreover, the processing of coconut husks into peat substitutes is usually resource-efficient, often using rainwater and solar energy. While transportation accounts for a substantial portion of total greenhouse gas emissions, research indicates that coconut-based peat substitues are still associated with lower emissions than peat.

However, when cultivating and processing coconut-based peat substitutes, social and environmental aspects must also be considered. These include fair working conditions, workplace safety, and the correct and safe application of fertilizers. The HORTICERT certification system for sustainable peat substitutes monitors these and other sustainability requirements throughout the entire supply chain. This allows consumers to trust that coconut-based peat substitutes have been produced sustainably – ecologically, socially and economically.
