Introduction:
A carbon footprint refers to the total greenhouse gas emissions—primarily carbon dioxide (CO₂)—produced directly or indirectly by a person, organisation, product, or process. In the context of hydrogen, it helps measure how clean the hydrogen really is, depending on how it’s produced and used.

🧠 What It Means
🌍 It reflects the true climate impact of a hydrogen project or technology.
🧪 Used to compare green, blue, and grey hydrogen sources.
📉 Reducing carbon footprints is critical for net-zero goals and green funding.
🚧 Key Challenges
🧾 Standardising how carbon footprints are measured globally.
🔍 Hidden emissions in supply chains can distort results.
⚙️ Not all hydrogen projects have transparent reporting or verified data.
🦁 Muzaffar’s Comment:
If we want hydrogen to truly lead the clean energy revolution, we’ve got to get serious about tracking its footprint. Numbers don’t lie!
🦉 Sameer’s Comment:
This made me realise not all “hydrogen” is equal. Just because something’s labelled as green doesn’t mean it’s clean unless the carbon footprint proves it.
