O carbono de carbono (CO2) constitui um dos gases mais importantes considerados contaminantes. Por isso, prioriza-se a geração de informações que contribuam para a caracterização da huella medioambiental gerada na área urbana e nos sistemas de produção animal representativos. Assim, o objetivo foi comparar a altura hombre a flutuação do nível de CO2 existente, em uma zona urbana/capitalina e em quatro modelos típicos paraguaios de produção animal: bovino de leite intensivo e semi-intensivo, pollos parrilleros (engorde intensivo) e cria /recria/engorde de porcinos (intensivo), de manera global y estratificada em franjas horárias. Para isso, se utiliza a tecnologia “IoT” (Internet of Things), desde um equipamento Smart Environment Libelilum®, que obtém leituras de CO2 e variáveis meteorológicas, transmitiéndolos em tempo real a uma plataforma digital. De maneira global, o prefeito promedio de partes por milhão (ppm) de CO2 foi observado no sistema de pollos parrilleros (512,77 ppm), seguido da zona urbana (372,94 ppm) e na última posição, se situou o galpón de produção bovina semi-intensivo (296,36 ppm), detectándose diferenças significativas entre os grupos (p<0,05). Mismo comportamiento se constatou nas franjas horárias; exceto em alguns intervalos (de 00:00 a 06:00 e de 18:00 a 00:00 horas; p>0,05). A concentração de CO2 na medida do ar no ambiente de sistemas de produção de leite bovino, de cerdos e de pollos parrilleros mostrou valores em geral baixos, que na maioria dos casos até se comparam favoravelmente com a medida do ar livre no ambiente urbano.
