Rural Urban Continuum Codes distinguish U.S. metropolitan counties by the population size of their metro area, and nonmetropolitan counties by their degree of urbanization and adjacency to a metro area. We connected where projects were performed to the RUCC of the project's corresponding county.
| 1: Metro Counties in metro areas of 1 million population or more | $16,176,900,458 | 33M tons CO2e increase over baseline |
|---|---|---|
| 2: Metro Counties in metro areas of 250,000 to 1 million population | $7,545,110,426 | 16M tons CO2e increase over baseline |
| 3:Metro Counties in metro areas of fewer than 250,000 population | $2,288,054,602 | 5M tons CO2e increase over baseline |
| 4: Non-metro, urban population of 20,000 or more, adjacent to a metro area | $981,147,889 | 2M tons CO2e increase over baseline |
| 5: Non-metro, urban population of 20,000 or more, not adjacent to a metro area | $354,577,043 | 730K tons CO2e increase over baseline |
| 6: Non-metro, urban population of 5,000 to 20,000, adjacent to a metro area | $907,930,033 | 2M tons CO2e increase over baseline |
| 7:Non-metro, urban population of 5,000 to 20,000, not adjacent to a metro area | $877,480,019 | 2M tons CO2e increase over baseline |
| 8: Non-metro, urban population of fewer than 5,000, adjacent to a metro area | $390,796,898 | 805K tons CO2e increase over baseline |
| 9:Non-metro, urban population of fewer than 5,000, not adjacent to a metro area | $988,561,545 | 2M tons CO2e increase over baseline |
