Different forms of
economic and engineering-based models have been applied to analysis
of greenhouse-gas policies. Although each of these efforts attempts
to integrate aspects related to energy, the economy, and the
environment, they differ from one another in important details. As a
result, these models are subject to one of two criticisms: Some
(“top-down”) are said to concentrate too strongly on economic
aggregates and trade flows and associated economic interactions, and
they fail to capture important micro-level details of energy
technologies. Others (“bottom-up”) are seen as too weighted down by
detailed descriptions of specific technologies, and thus are unable
to account for general-equilibrium adjustments that occur in an
economy, or on a world level through international trade.
The research is designed to gain the advantages of the
different model structures in a common study. The three linked
models being used are:
- the multi-sector, multi-region MIT Emissions Prediction and
Policy Analysis (EPPA) Model
- a version of the MARKAL model which is focused on its
transport sector
- a transportation demand model which projects aggregated
traffic volume and modal split over several-decade time
horizons
Goals/Objectives
The goal of the
work is to illuminate transport issues in greenhouse gas control
policy and to support a study of the joint application of these
different models to a common analysis task. The three models are
used to:
- formulate consistent scenarios on regional and global
transportation demand
- examine how the transportation sector would be affected by
energy sector CO2 reduction targets
- study how transportation sector emission targets can be
achieved at minimum costs in light of the projected
demand
