Bangladesh responds to severe air pollution. The global air quality is the worst in 2021. Its capital Dhaka is the world’s second largest pollution city. Vehicle emissions have made a significant contribution to this environment. To solve this problem, a study led by colleagues led by Sakie KAWSAR and Ahsanullah University of Science and Technology discussed the European emissions model, Copert 5.5, Bangladesh, to develop a comprehensive vehicle emission list.
The research team of AHSANULLAH University of Science and Technology includes Sakie Kawsar, Sourav Biswas, Muntasir Noor and MD Shahid Mamun. They used Copert 5.5 to analyze in detail to calculate the annual emission of various vehicle categories in Bangladesh in recent years. Based on the estimation of World Bank data, the results were tested on the results. This study was published in “Environmental Science: Atmosphere: Copert 5.5” is a suitable tool for Bangladesh, which indicates that the latest emission factor of CO2 And other pollutants.
The study emphasized that vehicle emissions accounted for a large part of the Bangladesh State Corporation2 Most of the emissions come from highway vehicles. The lack of tailor -made vehicle emissions models and comprehensive emissions inventory hindered the country’s effective air pollution management. Copert 5.5 is a widely used European launch model, which provides a strong solution for this issue. By using this model, researchers have developed emissions inventory of specific countries, thereby more clearly depicting vehicle pollution in Bangladesh.
Major results show that the Copert 5.5 model can accurately estimate the discharge of unique conditions in Bangladesh. This study calculates the annual production of CO2 From different vehicle categories, the results were compared with World Bank data, and there was almost no difference. The verification confirms the applicability of the model in the context of Bangladesh.
The research team found that the implementation of Copert 5.5 may lead to major improvement in air quality management. This model provides detailed insights on CO emissions2 There are more than a dozen major major pollutants, so that decision makers can make wise decisions. Kawsar said: “Copert is estimated to help update Bangladesh’s vehicle emissions standards by imposing new rules related to euro standards and fuel quality, thereby reducing the level of emissions.”
One of the key discoveries of the study is the update and emission factors of various vehicle categories. Researchers proposed a new company2 At present, the emission factors of vehicles operating in Bangladesh have more technologies. This update is essential for accurate emission estimates and effective policies. The discharge list of the study has made a comprehensive overview of the contribution of the country’s total emissions to different vehicles, highlighting the areas that need to be intervention.
By establishing a reliable emission model, the study paved the way for the extensive research of air pollution rates in the country. Government departments can use these estimates to formulate and implement more stringent emission standards, thereby helping to improve air quality and public hygiene.
In short, the research of Kawsar and his colleagues marked an important step towards Bangladesh’s better vehicle emissions management. The implementation of this model may lead to a significant positive impact on air quality, thereby solving one of Bangladesh’s most urgent environmental problems.
