Release Notes

2025-Q1 #

Fix to address incorrect reporting locations for the oil and natural gas sector
- Onshore petroleum and natural gas production and gathering and boosting facilities report aggregated emissions at the basin level, but frequently use the address of their U.S. corporate headquarters building as their reporting address. This results in headquarters buildings being incorrectly attributed for emissions occurring in a basin that may not be physically near the headquarters
- This fix removes emissions from onshore petroleum and natural gas production and gathering and boosting facilities, as reported in EnviroFacts
- Emissions from onshore petroleum and natural gas production and associated industry are already reported at the basin level, therefore this fix does not remove a source sector of emissions

Emissions data available for year 2024
Higher resolution mapping of area-normalized emissions across the United States
Toggle feature for normalizing emissions estimates by population and visualizing change over time in a histogram
Improved emissions estimation models:
- Refined Agricultural Emissions by removing burning crops to reduce artificial spikes (especially relevant to the state of Hawaii’s estimates)
- EGU (energy generating units) Hindcast Fixes: Aligned locations pre-2012 with EIA data
- Stabilized Forecast Ratios: Capped high EIA ratio values
- Updated Base Year to 2023 to use latest EIA SEDS (State Energy Data System) data for projections
- Added Biofuels/Renewables to AEO: Included previously missing projections for electricity generation.
- Smoothed NEI Data: Adjusted smoothing logic to match EIA fuel consumption trends
- Addressed missing data for airports in ingested FAA (Federal Aviation Administration) data

Per capita emissions calculations for cities across the United States, using US Census Bureau population data
With login credentials, comparison mode available: the ability to rank and compare cities based on various measures including emissions in different sectors
With login credentials: user can ‘pin to city’ for city of primary interest

Available with login credentials: PDF Reports for potential targets for the installation of new EV charging stations in underserved communities

Launched an open data portal at open.crosswalk.io, which provided free access to neighborhood-level emissions data for the entire United States
Data covered years 2010-2023 for Scope 1 emissions (direct emissions) and 2019-2023 for Scope 2 emissions (emissions from electricity consumption)
Data visualized in an interactive map with two views: area normalized and census tracts (census block group available with login credentials)
Scope 1 (direct emissions) sectors available: commercial buildings, industrial buildings, residential buildings, transportation
Scope 2 (emissions from electricity consumption) sectors available: total
Additional Scope 1 (direct emissions) sectors available with login credentials: airports, vehicles, power plants, mobile equipment, commercial buildings, industrial buildings, residential buildings, other
Additional Scope 2 (emissions from electricity consumption) sectors available with login credentials: commercial buildings, industrial buildings, residential buildings
Download CSV containing emissions inventories for: US Census Tracts, US Census Places (Cities), US Counties, US States, US County Subdivisions
Additional features available with login credentials: ability to download a PDF report containing a summary of the data and data visualizations
