In spite of the efforts of the footwear and textile industries to understand their greenhouse gas (GHG) emissions and develop reduction strategies, knowledge on the subject is still incipient. Given this scenario, this paper aims to identify, quantify, and present the main sources of GHG in this economic sector, followed by proposing solutions aimed at more efficient management. A qualitative and quantitative study was conducted with four companies in southern Brazil to achieve this purpose. Among the main sources of emissions are fuel and energy consumption. The main reduction alternatives include searching for alternative fuels and considering energy generation through clean sources. It is clear that implementing initiatives aimed at reducing emissions is not a simple task. However, the research highlighted the technical feasibility of new forms of production with a reduced environmental impact.

ABSTRACT: Most energy used to operate agricultural machines in the field is generated from fossil fuel combustion. The combustion process emits atmospheric pollutants, increasing the emission of greenhouse gases (GHGs). In this context, this review is to discuss technologies for mitigating diesel engine GHG emissions to advance sustainable development in the agricultural machinery sector. This paper presents strategies and technologies widely adopted by agricultural machinery manufacturers in controlling pollutant emissions during fuel combustion. The findings of this study encompass sustainable alternative technologies, such as selective catalytic reduction, exhaust gas recirculation, diesel particulate filter, and fuels. This study helps reveal the environmental impact of agricultural field operations that generate GHG emissions.
