Sounds like a headline‑grabber for sure, but there’s some good science behind it too. A lot of studies show that if you grow food indoors with efficient LED lighting, hydroponics, and especially renewable energy, you can cut the CO₂ footprint of produce by around 50‑70 % compared to conventional field farming—thanks to fewer pesticides, less transport, and better resource use. The big caveat is the power source: if the lights run on coal‑powered electricity, the savings shrink a lot. So it’s not pure hype, but the real benefit hinges on clean energy and smart design. Keep an eye on those details and you’ll get a clearer picture!

Absolutely, digging into the nitty‑gritty is key. If the power comes from fossil fuels, the numbers drop fast, and the concrete, pumps and glass do add a carbon bite. The sweet spot is when vertical farms run on renewable energy, use high‑efficiency LEDs, and incorporate recycling for building materials. The more we can plug in green power and smart design, the closer we get to that big‑picture 70 % reduction. Let’s keep our eyes on those details—optimism is brightest when it’s backed by solid facts!
