Ecological tax on industrial air pollution and its impact on reducing emissions in the cement industry: a case study of Lafarge Holcim cement company in Algeria

This study aims to highlight the importance of ecological tax in reducing air pollution caused by the cement industry. The focus is on limiting the emissions resulting from cement dust and polluting gases surrounding the Lafarge Holcim cement plant and its neighboring areas. The study explores the Algerian laws and decrees regulating the ecological tax on industrial air pollution, specifically the limits on dust and gas emissions set by Executive Decree No. 138/06, which governs the emission of dust, solid and liquid particles, and gases into the atmosphere. Among the key findings, the effectiveness of the ecological tax in reducing the amount of gas and cement dust emissions into the air surrounding the factory was evident. This includes gases such as sulfur oxides (SOX), carbon monoxide (CO), and nitrogen oxides (NOX). As a result, the company adopted an environmentally sustainable policy, investing in cleaner production technologies aimed at reducing greenhouse gases and cement dust emissions. This approach aligns with the ecological tax on industrial air pollution and demonstrates Lafarge Holcim's commitment to environmental sustainability.
