Due to the significant consumption of water, energy, wood and raw materials of mineral origin, the civil construction sector is the target of the search for green seals, adding technologies to avoid the waste of natural resources and waste disposal. Works that follow environmental principles attested by the seal cost 5% more. But, in addition to the reduction in costs after construction, the value of the development for resale is up to 20%, according to data from the Leed certification system, which exists in 127 countries. Among hundreds of works in the process of certification in the country, there are five of the 12 football stadiums that will host matches for the 2014 World Cup.

O setor de construção é um dos maiores consumidores de insumos extraídos tanto de florestas plantadas como das áreas naturais. No entanto, menos de 5% da produção madeireira nativa é certificada, conforme dados do Instituto do Homem e Meio Ambiente da Amazônia (Imazon). Mais de 40% têm origem ilegal.

Como há esquemas para fraudar o sistema de controle e a documentação, mesmo a madeira considerada legal não tem garantias quanto à extração sem práticas predatórias. “O gargalo para a expansão da certificação está na distância entre produtores e compradores”, atesta Leonardo Sobral, do Instituto de Manejo e Certificação Florestal e Agrícola (Imaflora).

According to him, the seal gives the wood an overprice of between 7% and 15%. “While buyers claim that there is a lack of certified product to meet the demand, producers say that the problem lies in the lack of interest in the more expensive product”, explains Sobral. Practically all certified production is destined for export. “With the falling dollar, the trend is for the producer to look at the domestic market as strategic”, he assesses. (SA)
