Use Cases - Crosswalk Labs

How Crosswalk Works for You

City Planning01

With Crosswalk, you can focus on solutions to solve your city's climate-related problems by knowing what emissions look like day by day, block by block. Our data supports action: community inventories, climate planning and emissions tracking over time, space, and emitting sector. We show you the high-resolution emissions landscape of your city, neighborhood or campus.

Project Siting02

From clean energy companies that want to know where to site their next projects, to carbon capture projects that are looking for locations with specific atmospheric or other strategic requirements, Crosswalk data can provide the intel. Crosswalk enables powerful mapping and spatial analytics to help users identify opportunities, assess risk, understand climate realities, and enhance location context.

Investment Intelligence03

Crosswalk data can provide intelligence to guide investment for the private sector. Specifically, Crosswalk data can fill information gaps in emissions assessments for assets held and managed by large investment firms and trusts. For example, asset managers can use Crosswalk data to understand how emissions would be impacted by potential partnerships or acquisitions. 

Health and Equity04

What if think tanks, journalists, and NGOs could use consistent data to drive effective policy change? Crosswalk emissions data can be aggregated by neighborhoods and layered with public health and demographic data to identify overlapping public health concerns and emissions hot spots.

Connecting Cities05

Regional collaborations in local government often struggle with a lack of apples-to-apples data for climate action. Crosswalk’s uniform methodology allows users to compare and contrast their emissions with others, speeding up the learning cycle and accelerating emissions reductions.

Trust-Based Advocacy06

What if communities competed to be the lowest emitters?  What if elected officials could run on, and then deliver, low-carbon policies for their communities? Crosswalk provides citizens, advocates, and media with reliable emissions data, verified against the atmosphere - so you know it is trustworthy.

Compare Cities

Learn what sustainable cities are doing to quantifiably reduce emissions, and connect with city leaders to put their insights to work for you.

Solve Converging Problems

Find opportunities to reduce greenhouse gas emissions while advancing priorities such as low-incoming housing, equity in health care, and transportation planning.

Crosswalk vs Status Quo

Crosswalk Labs has created spatially and temporally detailed estimates of fossil fuel CO2 emissions from all US cities using a methodology funded by NASA, NOAA and NIST.

Our products report for 50 states, 435 congressional districts, tribal lands, 3,000+ counties and 3,601 urban areas.

Status Quo
(typical)
Crosswalk Labs
Neighborhood level
No
Yes
Neighborhood level

Currently, cities estimate their emissions for the entire city and do not provide any information about emissions for individual neighborhoods, streets, buildings or other portions of a city.

Building scale
No
Yes
Building scale

Crosswalk Labs provides census block level data in every corner of the country and has building-level and street-level emissions data for over a hundred cities and can work with you to add your city..

Temporal resolution
Yearly
Daily And Hourly
Temporal resolution

The status quo is annual emissions, often spaced several years apart due to limited resources. Crosswalk Labs data are available for every hour during every day since 2010.

Atmospheric check
No
Yes
Atmospheric check

The status quo inventories are not scientifically verified by measuring CO2 in the air. Crosswalk Labs emissions data are validated in peer-reviewed scientific studies that use measured CO2 concentrations in the atmosphere to estimate sources and sinks.

Comparison between cities
No
Yes
Comparison between cities

The status quo inventories often differ between cities in the sectors, the scopes, and the methods used, making inter-city comparisons difficult. Crosswalk Labs uses the same sector definitions, scopes, and methods across the entire country, making apples-to-apples comparisons between cities easy.

Peer reviewed / public data
No
Yes
Peer reviewed / public data

Crosswalk Labs data have been developed through scientific research at several universities. The public data sources, methods, and results have been reviewed by experts and published in reputable scientific journals.

Accuracy
The mean absolute percent difference: 29%
1.4% (national), 2 and 3% (Indianapolis tested)
Accuracy

Most cities underestimate their emissions while some overestimate, resulting in estimates that are all over the map. Crosswalk data is compared with national measurements of a carbon isotope (C14) that is not found in coal, natural gas, or gasoline and so is a great way separating background CO2 from CO2 caused by the burning of fossil fuels.

Latency
2-3 years
3 months/realtime
Latency

Most city inventories are several years out of date by the time the data is assembled, the reports are written and published. Crosswalk data aggregation software downloads new data every night and updates to the emissions estimates are processed at least quarterly and we are constantly working to shorten that cycle further. Crosswalk Now-Cast uses our decade of data to inform our prediction algorithms, allowing us to estimate emissions in real time.

Consistency with EPA’s UNFCCC submission
No
Yes
Consistency with EPA’s UNFCCC submission

Crosswalk Labs data are categorized in a way that allows for streamlined reporting for the EPA’s UNFCCC submission and several common city-level protocols.

Now-cast and limited forecasting
No
Yes
Now-cast and limited forecasting

Crosswalk Labs data will be able to estimate today’s emissions and provide limited forecasting of emission into the future.

Incorporate remote sensing

Scope 2
Using large-scale averages
Grid model traced to US power plants
Scope 2

Crosswalk Labs data include emissions associated with electricity consumption, reflecting the amount and location of consumption as opposed to electricity production. Emissions associated with electricity production vs. consumption are often conflated in self-reported inventories, and the numbers are often based on averages.
