Introduction:
CO₂ emissions refer to the release of carbon dioxide into the atmosphere, primarily from burning fossil fuels. In the hydrogen space, it’s a key metric for judging how clean a hydrogen production method truly is.

🧠 What It Means
📉 Directly impacts climate change, global warming, and energy policy decisions.
⚖️ Used to differentiate hydrogen types: grey (high emissions), blue (reduced via carbon capture), and green (zero emissions).
📊 Investors and policymakers increasingly require CO₂ tracking in hydrogen project assessments.
🚧 Key Challenges
📌 Many hydrogen production methods (e.g. steam methane reforming) emit large amounts of CO₂.
🔍 Requires accurate measuring, reporting, and verification – which isn’t always consistent.
🛑 Greenwashing risk: Some “low-carbon” projects still have significant hidden emissions.

This is the number one stat that separates serious hydrogen efforts from hype. If we’re not cutting CO₂, what’s the point?
🦉 Sameer’s Comment:
It’s crazy how much the term “emissions” shapes the entire hydrogen conversation. I used to think it was just a buzzword—now I realise it’s the whole game.
