GHG measurement

Actionable GHG analysis to achieve carbon goals

Utilize local, data-driven transportation insights when measuring GHG emissions to understand where climate-focused initiatives will have the biggest impact on reductions. Pinpoint key focus areas where priority measures can be implemented to maximize carbon reduction efforts.

Get started

Get detailed and actionable data to reliably measure greenhouse gas emissions

1
Save time

Spend less time on the GHG emissions calculations and more time on developing mitigation strategies to reduce greenhouse gas emissions.

2
Ensure you measure what you can control

View different methodologies that analyze GHG within your jurisdiction or GHG from induced activity.

3
Stay ahead of GHG requirements

Fast access to the exact road-level emissions measurement data points that you need to analyze every region’s carbon footprint.

4
See the full picture

Break out trip type and vehicle type to see what drives emissions.

Eliminate the need to do a complicated calculation model with instant access to reliable GHG numbers

Get started
Performance measurement requirements

Get the exact outputs you need to calculate the newly required GHG performance metric baseline and reduction targets for your climate data.

GHG inventories

Calculate baseline on-road transportation GHG inventory for jurisdictions.

Project prioritization

Analyze segments or areas of high GHG for reduction targets, prioritization, and project needs.

Grants and funding

Easily establish GHG emissions baseline inventories to support funding opportunity requirements (e.g., Climate Pollution Reduction Grants) aimed at reducing emissions.

Sharing regional transportation emissions data

Read case study
The challenge

The Twin Cities Metropolitan Council wanted to measure emission sources and trends over time to provide communities with local GHG data to support mitigation efforts and address climate change locally.

Data-based solution

With StreetLight, they segregated vehicle ghg emissions produced by jurisdictions and townships for vehicles and trucks. The Council made the GHG inventory results publicly available online on the Twin Cities Greenhouse Gas Inventory, including data for each of the townships located within the Twin Cities metro. This allows planners to quantify vehicle emissions and select carbon footprint reduction strategies for their jurisdictions.

Metropolitan Council
We no longer have to make assumptions about people’s trip activity and travel behaviors. Now we have data to support our research, and it separates fact from fiction.
Panini Chowdhury
Transportation Planning Manager, City of Pittsburgh
As MassDOT plans its electrification transition…it made a lot of sense to base both [their and our] analyses on StreetLight to…have consistency between the transportation agency and the infrastructure side.

FAQs

Quick answers to questions you may have

Discover everything about StreetLight’s GHG Measurement product features, benefits, and more.

What is GHG measurement?

Greenhouse gas (GHG) measurement uses data on known emissions factors to understand the total volume of greenhouse gasses that are emitted by human activity in a given area. In the transportation industry, GHG measurement is mainly focused on measuring tailpipe emissions from internal combustion engine (ICE) vehicles, including personal vehicles and commercial trucks.

How are greenhouse gas emissions measured?

In transportation, greenhouse gas emissions are typically measured by total Vehicle Miles Traveled (VMT) within a specific area and time frame. Different fuel types (e.g., gas vs. diesel) have varying fuel efficiency and emissions, so truck activity (mainly diesel) is often calculated separately from personal vehicles (mainly gas). EV adoption rates are also considered to determine the proportion of vehicles producing tailpipe emissions.

Detailed VMT trip types (e.g., internal-internal) help determine which vehicle trips contribute to an area’s total emissions. For instance, a trip passing through City B on its way from City A to City C may not count towards City B’s emissions, as it’s not the trip’s origin or destination.

What data is needed to calculate GHG emissions?

StreetLight’s platform can provide the data you need to calculate greenhouse gas (GHG) emissions in your region, including VMT broken out by trucks vs. personal vehicles, EV avoided emissions, trip types (e.g., internal-internal, internal-external, external-internal, external-external), and induced-activity method vs within-boundary method.

What is the unit of measurement for GHG emissions?

GHG emissions are measured by total weight of CO2 or CO2 equivalent (CO2e) greenhouse gasses emitted in a given area. CO2e is used in order to account for the different levels of Global Warming Potential (GWP) of different gas emissions (such as methane or nitrous oxide) compared to the same amount of carbon dioxide.

GHG emissions are often measured in metric tons or kilograms of CO2e.
