The choice that would have the smallest impact on climate change when purchasing apples at the store is buying apples that have no packaging.
While reducing packaging can help minimize waste, the carbon footprint associated with the production, transportation, and cultivation of the apples themselves remains significant, regardless of whether they are packaged or not. In contrast, buying locally grown apples and purchasing in bulk have more direct effects on reducing the carbon emissions associated with transportation and storage. Buying from farms that use organic practices may also have positive environmental impacts, though the benefits can vary based on farming methods and location.
