Covering over 6,400 cities, Crosswalk Essentials helps you understand your community’s emissions and how your community compares with neighbors.
Explore our sample data from 2015
Includes all emissions from vehicles driving on roads such as cars and trucks within a city/town boundary, regardless of origin or destination.
Data come from the 2011 US EPA NEI, which reports CO2 emissions from the MOVES model. Scaling for other years is based on US EIA fuel data. Hourly profiles are built using FHWA CCS traffic data and emissions are distributed based on road type and fuel type, and using FHWA AADT data. On road emissions represent where the physical emissions occur and therefore include highway traffic going through a city even if a given vehicle does not start or stop in the city.
Includes emissions from commercial buildings such as restaurants, office buildings, stores, schools, churches, libraries, hospitals, military installations, and other government buildings.
Data come from the 2011 US EPA NEI and are scaled for other years using US EIA fuel data. Nonpoint buildings are distributed to census block groups and point sources are represented as points in space. Hourly profiles are from a building energy model for nonpoint emissions and EPA temporal surrogate data for point sources. Commercial sources are distinguished from industrial sources based on the source classification code (SCC) used to report emissions in the NEI.
Includes emissions from residential buildings such as houses, apartments and condominiums, and mobile homes.
Data come from the 2011 US EPA NEI and are scaled for other years using US EIA fuel data. Buildings are distributed to census block groups using FEMA building stock data. Hourly emission profiles are from a building energy model for nonpoint emissions.
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.The status quo is whole-city with no sub-city scale spatial information.
Includes emissions from airplanes and helicopters during taxi, takeoff, and landing, attributed to the city/town where the airport is located.
Emissions from takeoff and landing include emissions from below 3,000 feet above ground level. Data come from the 2011 US EPA NEI and are scaled for other years using US EIA fuel data. Data are represented as points, centered on the runway or helipad. Airport equipment such as baggage carts and buses are included in the non-road category.
Emissions are from power plants, attributed to the city/town where power plants are located.
These data come from three sources: CAMD hourly CO2 emissions from CEMS stack monitoring, the 2011 US EPA NEI and EIA fuel data. Scope 2 data will be available soon.
Emissions include Industrial, Commercial Marine Vehicles, Rail, and Cement.
Data come from the 2011 US EPA NEI and are scaled for other years using US EIA fuel data. Representation in space depends on subsector and hourly profiles come from EPA surrogate time profiles
