Table 1 Description of decarbonization scenarios and their implemented policies in ReEDS (see SI Table S-1 for a description of ReEDS carbon policy inputs for each scenario)
From: Air pollution disparities and equality assessments of US national decarbonization strategies
Scenario | Scenario description | Scenario approach | Source |
|---|---|---|---|
A | Base | Includes all current policies and standards (state renewable portfolio standards, tax credits, etc.) but implements no new carbon policies | |
B | US NDC | United States Nationally Determined Contributions via the 2015 Paris Agreement. Carbon cap implemented in ReEDS to follow emissions allotted | |
C | 1.5 °C Pathway | Based on policy required to maintain global warming under 1.5 °C. Carbon cap implemented in ReEDS to follow emissions allotted | |
D | 80% RE 2050 | National renewable energy mandate implemented beginning in 2020 at 20% and increased linearly to 80% renewable energy in 2050 | |
E | 100% RE 2035 | National renewable energy mandate implemented beginning in 2020 at 20% national RE generation and increasing linearly to 100% RE generation in 2035 | |
F | 100% RE 2050 | National renewable energy mandate implemented beginning in 2020 at 20% national RE generation and increasing linearly to 100% RE generation in 2050 | |
G | Low Carbon 2035 | National technology mandate implemented beginning in 2020 at 20% and increased linearly to 100% renewable energy, natural gas CCS, and nuclear in 2035 | |
H | Low Carbon 2050 | National technology mandate implemented beginning in 2020 at 20% and increased linearly to 100% renewable energy, natural gas CCS, and nuclear in 2050 |
