The building material manufacturing sector is one of the sectors with the highest consumption of fossil fuel resources. The “cradle-to-gate” study of the ceramic bricks made in the Āne plant of JSC „Lode”, Latvia is performed according to ISO standards 14044:2006. Life cycle inventory data have been collected at the factory site. Three different perspectives of the “Eco-Indicator’99” method are used to conduct an environmental characterization of the building materials to obtain the total impact indicator.
