This paper estimates and forecasts the green economies and green jobs in the USA states of Colorado and Pennsylvania. The industry distribution of green jobs in each state is estimated by NAICS code. The occupational distribution of green jobs in each state is estimated by detailed occupational classification and skill levels. Green jobs for each state are forecast for the coming decade. We find substantial differences in the size, structure, distribution, and forecasts of green jobs in each state. We determine that the number of future green jobs in a state is determined by the increasing portion of total jobs in the state comprised of green jobs and the rate of growth of employment in the state, and that green jobs in Colorado are forecast to increase much more rapidly than in Pennsylvania in both percentage and absolute terms. We determine that these changes will alter the future distribution of U.S. green jobs among the states. We also find that the distribution of green jobs among industry sectors in the two states differs significantly. Finally, we find that there are substantial differences in the industrial and occupational distributions of green jobs in Colorado and Pennsylvania. We discuss the implications for Colorado, Pennsylvania, and other states seeking to implement ambitious green initiatives.
