DaaS — Decarbonisation-as-a-Service
Retrofit any diesel engine with zero upfront cost. Pay a predictable monthly fee that is always lower than the value of fuel saved — verified by GreenVision.
Zero CapEx. Zero Risk. Guaranteed Outcomes.
DaaS makes large-scale decarbonisation simple and financially attractive. Instead of buying the retrofit system, you pay a monthly subscription fee that is always less than the fuel you save. Saarthi handles installation, maintenance, warranty, spares and monitoring — while GreenVision verifies real savings and CO₂ reduction in real time.
