TThe effect of greenhouse gases (GHG) is a natural phenomenon essential for the existence of life in the land. However, human activities have aggravated this phenomenon, causing numerous problems environmental issues related to the accumulation of waste involved in the greenhouse effect. Therefore, in Brasília, capital of Brazil, located in the Federal District (DF), only 300 tons (12%) of urban waste are recycled, and this activity is carried out by collectors, who work independently or organized in cooperatives or associations. The goal of this research is to help understand the environmental and climate benefits of work of recyclable material collectors to reward their service. The investigation generates information that can help raise awareness among those involved in waste management for investment in reverse logistics schemes, in the circular economy and in the social and solidarity economy, prioritizing environmental and climate protection through selective collection and recycling of waste. The following variables were considered: type and quantity of waste solids collected, type of machines used, energy sources and transport routes. therefore, data analysis verified that the waste picker organizations contribute significantly to the reduction of greenhouse gas emissions and the energy saving.

The article presents the importance of collectors for urban sustainability and how their work helps to reduce carbon emissions, for example, improving land use, preserving and expanding green areas, removing waste at source and facilitating energy systems innovative technologies, such as biogas. Not only that, the research provides a portrait of collectors' experiences and perceptions about climate change and how environmental impacts affect their health and routine. Another point to comment on is the lack of government support and the urgent need to align federal, state and local efforts to provide waste pickers with a social safety net, appropriate technology and emergency support.
