Carbon Tracker App

Welcome to the CURE100 household Carbon Tracker App which enables you to make  informed choices to reduce your household carbon emissions.  This tool will help you estimate and understand your household’s emissions and compare them with others in your zip code.  You will find ways to reduce your carbon footprint in each category, and a way to document your future decarbonization intentions.

The global per-capita footprint is about 6 tons of CO2 and the U.S. average is about 16 tons. This tool will help you plot your way to low single-digits where we all need to be very soon.

In many cases, by reducing carbon emissions you will have the opportunity to save money, too.  Please read our FAQs to learn more about the Carbon Tracker App and get prepared for your household carbon assessment.

REGGIE (Regional Greenhouse Gas Inventory Estimator) is part of CURE100’s Carbon Tracker software suite. Use of the software is free to all, and does not require a userid or profile. REGGIE is also available as a tab in the Carbon Tracker. REGGIE provides a community-wide Greenhouse Gas (GHG) inventory for any zip code or combination of zip codes in the U.S. Many Towns, Districts, Villages and Counties would benefit from knowing their Greenhouse Gas (GHG) inventory. We call this a “baseline” inventory because it is the starting point for community-wide carbon literacy and decarbonization efforts. By knowing a baseline inventory, you can use REGGIE to understand which emissions are the “heavy hitters” and create a quantified decarbonization plan. See this fact sheet to learn more about REGGIE, how to use it and what’s in the report it produces.


The BEST (Bus Electrification for Student Transportation) framework allows for easy comparison of electric school buses and fossil fuel buses. Use of the software is free to all, and does not require a userid or profile. BEST is also available as a tab in the Carbon Tracker. It automatically produces graphical charts of Total Cost of Ownership and Cumulative Carbon Savings. It also serves as a repository of resources to convince School officials, transportation staff and the voting public about the benefits of electric school buses in a quantified manner. Note: the BEST framework is an Excel spreadsheet. The first step is to download the spreadsheet (do not try to fill in the spreadsheet online).  See the “Intro” tab for instructions. Please email us if you have any problems or questions, or would like to provide feedback.
