Quantificação e valoração monetária do carbono urbano na cidade de Corrientes, Argentina.
Palavras-chave:
serviços ecossistêmicos, infraestrutura verde, economia ambiental, biomassa florestal urbana, créditos de carbonoResumo
Este estudo analisa a capacidade de sequestro e armazenamento de carbono das árvores urbanas na cidade de Corrientes, Argentina, e sua valoração econômica como um ativo ambiental. Utilizando equações alométricas específicas para árvores e palmeiras, foram estimadas a biomassa aérea e subterrânea, o carbono armazenado e o dióxido de carbono equivalente. Os resultados mostram que as árvores urbanas armazenam 844 toneladas de carbono (3.098 tCO₂e), concentradas principalmente no Parque Costanera Norte e no Parque Camba Cuá. A biomassa arbórea representa mais de 99% do total, enquanto as palmeiras contribuem apenas marginalmente. A valoração econômica, baseada em um modelo de precificação hedônica, apresentou valores entre US$ 13 e US$ 37/tCO₂e, de acordo com diferentes cenários de certificação e risco. Esses resultados demonstram a influência dos benefícios urbanos, da qualidade metodológica e da governança da informação na disposição a pagar. O estudo posiciona as árvores urbanas como infraestrutura natural estratégica para a mitigação das mudanças climáticas e a geração de ativos ambientais locais. A conclusão é que a integração de inventários georreferenciados, sistemas de Monitoramento, Relato e Verificação (MRV) e estruturas regulatórias robustas permitiria a incorporação do carbono urbano em esquemas de financiamento verde e compensação de emissões em cidades do Cone Sul.
