Worried about consuming bananas from overseas? Do you believe they have a high carbon footprint?
We know that it seems more eco-friendly to eat local food, but … is this really true? Is there a scientific basis for asserting this?
But what’s more amazing than simply describing a fact? Analyzing data! And we have found a great source of info that solves all our doubts concerning the origin of food chain greenhouse emissions: Our World in Data.
So, let’s find out where the emissions from bananas come from.
If you had concerns because the banana that reaches your table comes from far away … don’t worry!
Because the key to reducing your carbon footprint does not lie in the point of departure of your food but in its nature.
Everyday we are more concerned about climate change. We care about the environment and the impacts that human activities generate in it. Among these activities is transportation. A process from the supply chain that accounts for a very small percentage of emissions. Therefore, sometimes eating locally has a significant impact on the carbon footprint. Why? Because, as we have already mentioned, transport is not responsible for a large share of food’s final carbon footprint (Source: Our World in Data).
The conclusion that to eat certain local food has many times the carbon footprint of most other foods was addressed by “the largest meta-analysis of global food systems to date, published in Science by Joseph Poore and Thomas Nemecek (2018)” (Source: Our World in Data).
Poore and Nemecek analyzed the greenhouse emissions across the whole supply chain. That is, the emissions generated by each of the following stages of the food supply chain:
