Creating ecosystems of climate truth: How can cities defend information integrity?

from Cities 1.5 · host University of Toronto Press

From fossil fuel lobbying to coordinated political disinformation campaigns, vested interests have built a profitable disinformation infrastructure designed to spread confusion, polarize debate, and exhaust the public. The good news is that the world is waking up. For the first time in the history of the COP, a Declaration on Information Integrity was agreed upon, with governments committing to address climate disinformation and promote accurate, evidence-based information globally.But we need to go further upstream - instead of simply fighting falsehoods, we need to build ecosystems where truth can take root and flourish. In this episode, we look to Brazil and speak to an individual who was integral in bringing information integrity both to COP and the international agenda. She makes the case for cities as one of the most powerful forces in reclaiming the narrative, building the infrastructure of truth from the ground up - one community at a time.Featured guest: Thais Lazzeri, Investigative Journalist and Founder of FALALinks:Declaration on Information Integrity on Climate Change - UNESCOIntegrity Information Observatory - OiiMentiro Tem Preco (Lies Have a Price)Climate Information Integrity5 Million Acts for Truth - FALATomorrow is today - YouTube (Portuguese)500 Grams of Life - Thais Lazzeri (Portuguese) ‘Democracy on the line’: Brazil’s election and the Bolsonaro disinformation ecosystem - Columbia Journalism ReviewEnvironmental and Climatic Disinformation in Northern Brazil: Dynamics and Impact in the Context of COP-30 - Heinrich Boll StiftungEnvironmental journalism and the struggle against disinformation in Brazil - Frontiers in CommunicationIf you want to learn more about the Journal of City Climate Policy and Economy, please visit our website at https://jccpe.utpjournals.press/Listen to the Cities 1.5 five-part miniseries “Going Steady with Herman Daly: How to Unbreak the Economy (and the Planet)" here: https://lnk.to/HDMiniSeriesCities 1.5 is produced by the University of Toronto Press and the C40 Centre, and is supported by C40 Cities.
