• Reducing human-caused CO_2 emissions to acceptable levels must become a global objective of our modern society. One way to meet this objective is to introduce a constraint on household annual CO_2 emission (HACO_2). However, behaviors that reduce CO_2 emissions, may appear too expensive, or to worsen living conditions. Although the goal of controlling CO_2 emissions is widely accepted, in practice it is not easy to reduce energy consumption. This paper develops a CO_2 emission trading scheme (CETS) framework for households based on the definition HACO_2. In this study, a city's CO_2 emission is assumed to be the sum of all HACO_2. The CO_2 constraint for a single household is determined by the city's total CO_2 emission reduction target. Multi-agent simulator is applied to clarify household behavior-selections under such constraint, and to find the effects of total CO_2 emission within the urban model. Simulations are performed with CETS (Case 1) and without CETS (Case 2). Results indicate 1) Under a CO_2 constraint, agents choose behaviors to meet the HACO_2 constraint. Total CO_2 emissions within the urban model decrease toward the pre-determined reduction target. 2) The CETS framework for household level is proved not only cost-efficient but also promotes the process of reducing CO_2 emissions. 3) An agent that acts for self-benefit will not consider the completeness of the total target. As a result, the reduction target within the urban model is never achieved even with the implementation of CETS.
