This study investigates the impact of replacing diesel with Compressed Natural Gas (CNG) on pollutant reduction in the state of Maranhão. The research highlights a significant decrease in emissions of greenhouse gases (GHG) and local pollutants, such as carbon monoxide (CO), carbon dioxide (CO2), and non-methane hydrocarbons (NMHC). Based on the analysis of data from the Greenhouse Gas Emissions and Removals Estimation System (SEEG), it was possible to quantify a reduction of approximately 3g/km of CO2 when replacing diesel with CNG. Additionally, a CNG refueling infrastructure is proposed, based on the supply forecast for the second half of 2024, which is mapped and analyzed. This study reinforces the importance of policies to encourage the use of CNG to promote more sustainable and less polluting transportation in Maranhão.
