v. 1. No vol. title -- v. 2. Greenhouse gas emissions. This document is the second in a series of annual reports designed to provide data and information on alternative-fueled vehicles (AFVs) and alternative and replacement transportation fuels. Section 503(a) of the Energy Policy Act of 1992 (EPACT) directs the Energy Information Administration (EIA) to estimate annually the number of AFVs in use in the United States, the amount and distribution of replacement fuel, and the greenhouse gas emissions likely to result from replacement fuel use. Section 503(b) directs suppliers of AFVs to report annually the number and type of AFVs made available in the previous year and those that the supplier plans to make available in the following year. This document, Volume I of Alternatives to Traditional transportation Fuels 1994, includes estimates of the number of AFVs in use (AFV inventory), estimates of alternative and replacement fuel consumption, and data on AFVs made available. The estimates are based on information as of October 1995. Volume 2, to be published at a later date, will contain estimates and information for greenhouse gas emissions resulting from replacement fuel use.
