Hi, the Green Score methodology currently encourages consuming organic food as a more sustainable choice, applying a big bonus to the score for foods with organic certifications.
However, most research shows that organic food has no meaningful difference in greenhouse gas emissions between organic and regular farming, organic farming uses much more land and slightly less energy. The environmental impact of organic farming is about the same as that of conventional farming, and if anything, may actually be worse. See, for example:
