Abstract

In Vietnam, the brick production is one of the construction material production sectors that has generated large emission of CO2 - the major greenhouse gas, since it consumes a large amount of fossil fuels. This research aims at conducting the surveys and estimating the CO2 emission factors for the kiln technologies used dominantly in brick production sector in Vietnam, namely Tunnel, Hoffman, and Vertical Shaft Brick Kiln (VSBK). For this purpose, field surveys were conducted in the selected provinces/cities in the North Vietnam including Ha Noi, Phu Tho, Bac Giang, and Thai Binh to collect data related to the existing operation of brick factories. The results of data analysis have shown that the highest CO2 emission factor was found with Hoffman kiln, followed by that of Tunnel kiln. Among kiln technologies, VSBK has expressed the lowest CO2 emission factor. These CO2 emission factors can be used in evaluation and prediction of the CO2 emission amount from brick production under different scenarios, which would be the helpful tool for policy-makers in proposing and establishing policies/strategies for reducing CO2 emission from brick production sector, contributing in mitigating the impact of climate change in Vietnam.

Keywords: Brick production sector; kiln technology; CO2 emission factors; Vietnam.
