On 22 November 2025, Brazil’s National Council for Advertising Self-Regulation (CONAR) introduced new rules to combat greenwashing in advertising. The changes cover biodiversity, climate change, and waste disposal, reinforcing the sector’s commitment to environmental protection.
Two new articles encourage responsible socio-environmental communication and set guidelines for sustainability claims and technical terminology.
Advertisers must provide detailed data on emissions, carbon offsets, and product life cycles, along with specific deadlines and action plans for environmental goals. These changes aim to ensure transparency and prevent misleading sustainability claims.
