Frequently Asked Questions
Does EIA report water vapor emissions data?
No. Water vapor is the most abundant greenhouse gas, but most scientists believe that human activity has a very small direct effect on its concentration in the atmosphere. Thus, EIA does not estimate emissions of water vapor.
Research by NASA suggests a stronger role from the indirect human effects on water vapor concentrations.
