Verifiable Scientific Sources

Our Calculation Science

We prioritize scientific clarity. Review the math formulas, emission coefficients, and reference databases that power our simulation models.

Reproducible Math Formulas

Our computation core is built using static algorithms in TypeScript. There are no AI estimates, guesses, or generative models editing your metrics—language models are restricted to explaining the calculated breakdown.

Aura Classifications

Deterministic score ranges mapped to sustainability feedback levels:

Green (Optimal)< 2.3 t CO₂e / year
Conforms to global sustainability benchmarks for limiting warming
Emerald (Sustainable Average)2.3 - 4.7 t CO₂e / year
Fits below median targets, on track for transition
Sapphire (Transition Zone)4.7 - 8.0 t CO₂e / year
Typical regional emission rates, optimization recommended
Amber (High Intensity)8.0 - 14.0 t CO₂e / year
Exceeds standard limits, key reduction areas flagged
Crimson (Extreme Footprint)> 14.0 t CO₂e / year
Highly resource-intensive profile, immediate shifts required

Scope & Computation Boundaries

This platform functions strictly as an educational simulator. The calculated values represent estimates of Scope 1 (direct travel emissions) and Scope 2 (residential utility usage) footprints based on public datasets. This model is not an official environmental audit and does not track the complex supply chains of physical consumer products, food waste, or micro-waste streams.
