Organic cucumbers and tomatoes are often less environment-friendly than their conventional counterparts.
Applied Plant Research (PPO) published a report last week with this conclusion. The main reason given is that organic production is less efficient than conventional methods and therefore produces more gas emissions per fruit. The report provides an overview of the environmental performance of different organic agriculture sectors. In dairy and arable production it is the organic sector that does better as was expected. In green house horticulture however the results are the other way round, to the extent that organic cucumbers produce three times as much pollution as conventionally grown cucumbers.
