The Mobility Carbon Engine (MCE)

A carbon widget for your mobility platform

The Mobility Carbon Engine (MCE) is a turn-key and client-based system that automatically quantifies carbon emissions, according to Greenlines' ISO14064-2 quantification methodology, generated by trips completed by end-users of a mobility platform, and generates GHG emission reductions which, once verified, can generate Verified Carbon Units (VCUs, or more commonly named 'carbon offsets') to be sold in the carbon markets.

Carbon reductions are produced by each user completing a trip and taking into consideration several factors, such as the transport mode used and the jurisdiction where the trip occurred. The MCE calculates in real-time the net carbon reductions generated by each trip, aggregates them with others, and generates the data required for verification by an accredited third-party verifier. All of this happens in real-time and with no manual involvement from the platform owner.

The result is a set of data ready for verification by an independent third-party Verification and Validation Body (VVB). Once verification is completed, offset certificates are issued which can be monetized as carbon offsets/credits, typically in the voluntary markets.

Before the Run



The mobility app captures the decision-making process of the end-user, provides a low-carbon transport choice, and tracks the user's geolocation until the destination.




The MCE automatically calculates the GHG emissions for the suggested route, its custom baseline, and the GHG emission reductions upon trip completion.




Trip data is regularly verified by a third-party validation/verification body (VVB). Once the verification is complete, Verified Carbon Units (VCUs) are issued to be sold in the market as carbon offsets.


A Powerful Carbon Monetization Engine


The MCE automatically quantifies the carbon impact of every completed trip by tracking the geolocation of the users, among other data points, and compares it to its custom baseline. It also generates verifiable carbon reductions for each trip to be converted into carbon offsets and ultimately into offset revenue.


The MCE has been generating verifiable GHG emission reductions and carbon offsets since 2019, as part of the trip planning app, Cowlines. GHG emission reductions generated by the MCE have successfully been verified by an independent third-party verifier and sold as offsets.


Thanks to its regional customization, the MCE is able to quantify carbon reductions in most parts of the world simultaneously or independently from each other. The MCE has all U.S. and Canadian jurisdictions already mapped out for customers to use right out of the box.


The MCE provides regional project and baseline emissions for most land, water, and air-based transport modes, including public transit, ride-hailing, taxicabs, e-scooters, pedal bikes, and more. In fact, Greenlines has already developed emission factors for the 30+ most common transport modes across North America.


The MCE acts as a turn-key "widget" that integrates into the back-end system of the client's mobility platform. It converts mobility data from each user (ie. distance traveled, transport mode, occupancy, region, etc) into verifiable GHG emission reductions. The integration phase ranges from one to six months, depending on the complexity of the client's system.


The MCE can be easily implemented to generate offsets from both small mobility providers (ie. bike share programs, carpooling companies) or local public transit agencies, to large mobility organizations (ie. mobility aggregators) operating simultaneously in multiple jurisdictions. The MCE is capable of handling both scenarios.


User privacy is paramount in the mobility sector. That is why the MCE is integrated into the client's server and in no case, data is shared with Greenlines. Your data is always yours.

Your Data Stays With You

In order to guarantee that user data is never shared with Greenlines, the MCE is integrated into the client's server and is under the client's complete control.


Use Cases

Greenlines' app-based Mobility Carbon Engine (MCE) can benefit most mobility players. Think of it as a 'widget' that plugs into your back-end system and automatically quantifies the carbon impact of each ride, calculates the carbon reductions generated, and aggregates them making them ready for verification by a third-party.



Mobility aggregators are the prime users of the Carbon Engine. Apps that provide real-time trip planning functionality for public transit agencies and/or provide mobility providers, including ride-hailing, bike-sharing, car-sharing, micromobility, and even personal pedal bikes, can harvest carbon reductions generated by its users with Greenlines' patent-pending Carbon Engine.

Using a Touch Phone

Experience the MCE first-hand

The Cowlines app, a free multimodal trip planning app available on the App Store, was the first to integrate the Mobility Carbon Engine (MCE) in 2019, allowing the automatic quantification of carbon emissions generated by each trip across the largest 62 U.S. and Canadian cities.

Cowlines seamlessly combines public and private mobility providers to find the most efficient multi-modal trip option for you. It also allows you to compare your selected option with an equivalent private vehicle trip to understand the carbon impact of both options.

Offset Quality Criteria

Greenlines' Mobility Carbon Engine (MCE) is powered by our proprietary Modal Shift Optimization GHG Quantification Methodology, developed according to ISO 14064-2; this ensures the app-based carbon offsets generated by the MCE not only meet the highest standards, but are also more likely to drive a higher price in the marketplace compared to other offset projects such as forestry projects, industrial processes, renewable projects, and others.


Offset revenue plays a critical role in making mobility projects from providers and aggregators possible.


Carbon reductions cannot be reversed as they are recognized upon trip completion.


Ownership of GHG reductions transferred from end-user to platform owner upon app download.


  • Baseline emissions: single user, group, jurisdiction scenarios

  • Project emissions: most accurate data available

  • No leakage

  • Scientifically sound and methodologically robust measurement, data collection, and calculations 

  • Robust monitoring and verification of project performance


Applicable Transport Modes

Commuting to Work


Walking, running, or using your personal bike or scooter are the best ways to stay healthy while moving around. Plus, if it replaces a vehicle trip when commuting to work or school, it is also a great way to help the environment! Thanks to geolocation devices, the MCE can quantify and recognize emission reductions against a predefined baseline, enabling the monetization of these reductions via offsets.


Buses, subways, and other forms of public transport modes are some of the most environmentally friendly transport options in cities. The MCE quantifies the carbon reductions generated by each trip taken by an end-user, enabling public transit agencies to generate valuable revenue to maintain and expand their fleets. The MCE enables the monetization of trips taken with any vehicle within the agency's entire fleet, including existing diesel vehicles, and not only the new and more efficient LNG, BEV or Hybrid vehicles.

Public Rental Bikes


Shared e-scooters, bike-share programs, and electric mopeds are very popular and for good reason! They are fast, fun, inexpensive, and most importantly, environmentally friendly. Micromobility providers, through their proprietary apps, can quantify and aggregate carbon reductions generated by their users and generate a new revenue stream to support and expand their operations.


Shared mobility such as ride-hailing (Transportation Network Companies, or TNC), ride-sharing, carpooling, and even taxis are an increasingly popular transport option for millions of commuters across the world.
By sharing rides, or through the use of low-carbon vehicles such as hybrids or EVs, these mobility providers can generate quantifiable carbon reductions and associated revenue to accelerate the adoption of sustainable transportation, both by end-users as well as within their supply chain.
