For the top 10 emitters, shown in the graph above, the results are variable.
The coming years will be a crucial time for power sector decision-makers to make choices about how power will be generated in the decades to come, as a significant fraction of existing U.S. power plants are approaching the end of their useful life.
Cutting power sector emissions is not new at the state level. According to the 2011 U.S. data available through CAIT 2.0, 42 states reduced their emissions relative to 2005, the baseline used in the U.S. GHG reduction pledge.
The power sector comprises the largest share of U.S. GHG emissions, contributing nearly one-third of all emissions from all sectors.
The CAIT 2.0 U.S. data, together with data from the U.S. Energy Information Administration (EIA), show the historic trend of power sector CO2 emissions. Between 1973 and 2005, U.S.
The emissions landscape within states can be diverse. The graph above shows the percentage of state GHG emissions that come from the power sector (in blue).
Annex I country-reported greenhouse gas emissions to the Secretariat of the United Nations Framework Convention on Climate Change.
This data collection focuses on the solar PV and wind industries in China, Germany, India, Japan, and the United States (U.S.).
The CAIT 2.0 U.S. State GHG emissions collection applies a consistent methodology to create a six-gas, multi-sector, and comparable data set for all U.S. states. CAIT 2.0 enables data analysis by allowing users to quickly narrow down by year, gas, state, and sector.
The CAIT 2.0 Country GHG emissions collection applies a consistent methodology to create a six-gas, multi-sector, and internationally comparable data set for 186 countries. CAIT 2.0 enables data analysis by allowing users to quickly narrow down by year, gas, country/state, and sector.
