Coprodução e critérios ambientais de baixo carbono nas compras realizadas pelo município de Aracaju

Abstract

Objective: To analyze coproduction practices in the definition and implementation of lowcarbon environmental criteria in the public procurement of the municipality of Aracaju (SE), Brazil, between 2010 and 2025, understanding how collaborative mechanisms among the State, market and society relate to sustainability and innovation in public administration. Methodology: A single case study, quantitative and descriptive in nature, based on the documentary analysis of 482 municipal procurement notices, systematized through a structured checklist and processed by cluster analysis (Jaccard distance), a Low-Carbon Indicator (IBC), a linear mixed-effects model and structural equation modeling (DWLS estimator), complemented by the mapping of the applicable regulatory framework. Main results: The environmental stringency of the notices grew systematically over the period (β1 = 0.0151; p < 0.01), driven by Law No. 14,133/2021, but anchored in a compliance logic: low-carbon criteria concentrated in execution clauses (99.6%) and were residual in the competitive bid-evaluation phase (3.9%) and in life-cycle assessment (0.37%). Intra-organizational variability exceeded inter-organizational variability, revealing inconsistency in the institutionalization of practices. Certain documental elements associated with collaborative mechanisms (coproduction) showed a statistically significant association with circular economy in the execution phase (0.465) and with the use of technologies and ESG criteria (0.760), evidencing co-responsibility among actors as a condition for the effectiveness of low-carbon procurement. Relevance and originality: The study is innovative in integrating coproduction and low-carbon public procurement in an important Brazilian state capital, articulating normative, technological and participatory dimensions aligned with SDGs 11, 12, 13, 16 and 17. Theoretical, methodological and management contributions: It proposes a theoretical-empirical model grounded in a PRISMA review, builds the Low-Carbon Indicator (IBC) and offers practical guidelines for the sustainable management of procurement, supporting a technicaltechnological product for the analysis, ranking and monitoring of notices. Social/societal contributions: It strengthens democratic legitimacy and socio-environmental responsibility, promoting more resilient, inclusive and low-carbon cities.
