Resumo
Sustainable development is a highly discussed reality in world’s context. Related to that, it can
be said that it is about respect with nature during economy and society development of a certain
region. If so, with the growth of civil construction and industrialization of today’s world, each
time growth atmospheric emissions, solids and liquids, harm the environment and causing
damage to the greenhouse effect caused mainly by increasing the concentration of carbon
dioxide in the atmosphere. Thinking about the impact caused by those emissions was created
the tool of Life Cycle Assessment, which is capable to measure all emissions involved in
services and materials life cycle. Using this tool in civil construction, specifically in the service
of internal mortars, this paper aimed in making a comparison between two materials emissions
of CO2, which are alternatives able to make the internal mortar, the regular mortar prepared in
site and industrialized mortar. Going through the process of obtaining data along industry and
sellers, and making a data collect about mortar consumption inside two constructions in the city
of Goiânia, was possible do set the comparison, getting the conclusion that despite being highly
industrialized, the industrialized mortar shows a better performance with regard to CO2
emissions, ie, emits a lower amount of gas to achieve the same service. Part of the explanation
for that is the logistic adopted for using industrialized mortar, which requests a change in the
using process. It is also possible to realize that the better performance toward regular mortar is
due the high consumption of electricity needed to use this, making the Brazilian energy matrix
responsible for a large amount of carbon dioxide emissions in the atmosphere.
