ECOLOGY CALCULATOR
Sustainable Procurement
A precise tool.
What is the Sustainable Procurement & How does it work?
Sustainable procurement integrates environmental criteria into purchasing decisions, encouraging suppliers to adopt greener practices and reducing the ecological footprint of an organization’s supply chain.
By quantifying the carbon intensity of purchased goods and services, businesses can identify high‑impact categories and shift spend toward lower‑emission alternatives, directly contributing to climate‑change mitigation goals.
The calculator estimates annual CO₂ emissions from procurement activities and highlights potential savings when a portion of spend is allocated to sustainable products.
E_{total}=S\left[(1-p)\cdot\alpha + p\cdot\beta\right]
S = total procurement spend (USD)
p = proportion of sustainable spend (fraction)
\alpha = emissions factor for conventional procurement (kg CO₂ per $)
\beta = emissions factor for sustainable procurement (kg CO₂ per $)
p = proportion of sustainable spend (fraction)
\alpha = emissions factor for conventional procurement (kg CO₂ per $)
\beta = emissions factor for sustainable procurement (kg CO₂ per $)
