A Ton of CO2 must be Additional in order to be sold
Additionality:
But for the Project (that weatherizes homes) the energy
savings would not have happened

The performance standard is a benchmark above which energy improvements in the
home are not business as usual

Benefits of Selling CO2
1. Revenue for energy efficiency retrofits
2. Comprehensive, transparent, & verified data
1. Proof of public benefits
2. Managing projects
3. Tracking performance
4. Analysis and reports
![Page 24: For National Association for State Community Services Programs Turning Carbon Savings from Residential Energy Efficiency Retrofits into a New Revenue Stream.](https://reader035.fdocuments.net/reader035/viewer/2022062620/5519c992550346443e8b47c6/html5/thumbnails/24.jpg)
Steps to Bring Carbon Savings to Market
1. Scope and Plan Project
2. Identify and Manage Carbon Data
3. Write Project Description
4. Validate Project Description
5. Verify Offsets
6. Register and Sell Offsets
