Transport accounts for 24% of global CO₂ emissions. Understanding your vehicle's footprint — from tailpipe to full lifecycle — is the first step toward a cleaner planet.

What is Carbon Emission?
Carbon emission refers to the release of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere. When vehicles burn fossil fuels like petrol and diesel, they release CO₂ that traps heat, contributing to global warming and climate change.
🏭
Tailpipe Emissions
CO₂ released directly from a vehicle's exhaust during combustion. This is the most visible and immediate form of vehicle pollution. Electric vehicles produce zero tailpipe emissions.
🔄
Life Cycle Assessment
The complete carbon cost — from mining raw materials and manufacturing, through all years of driving, to final disposal. LCA gives the most accurate real-world picture of environmental impact.
♻️
Disposable / End-of-Life
Emissions from scrapping, shredding, and recycling a vehicle at the end of its life. EVs score higher here due to the complexity of recycling lithium-ion battery packs.
Why Does It Matter?
🌡️
Global Warming
CO₂ from vehicles traps heat, raising global temperatures and causing extreme weather events.
🫁
Air Quality
Exhaust gases cause respiratory diseases, especially in cities with heavy traffic density.
🌊
Rising Sea Levels
Melting ice caps due to global warming threaten coastal cities and millions worldwide.

What is NetZero?
NetZero is a vehicle carbon footprint calculator that helps individuals understand the real environmental cost of their transport choices. We measure emissions across three dimensions — tailpipe, full lifecycle (LCA), and end-of-life disposal — giving the most complete picture available.
The project was built as part of academic research at DSEU Dwarka to promote environmental awareness and data-driven decision making in transport.
