As global leaders gathered in Belém for the UN climate conference, a prominent Brazilian billionaire took the stage to champion sustainable urban growth—yet his own real estate enterprise is entangled in legal disputes over environmental degradation.
Rubens Menin, whose net worth is estimated at $2.2 billion, leads a newly formed working group on sustainable cities at COP30. This panel aims to provide policymakers with successful private-sector models for urban development. However, court documents reveal that his company, MRV, is accused of causing ecological damage in two separate cases.
In one instance, a criminal conviction against MRV for dumping untreated sewage into a stream was overturned during the climate summit. The judge ruled that the statute of limitations had expired, as the offense dated back to 2015 and the state delayed prosecution.
A separate civil lawsuit alleges that MRV flooded farmland in a historic quilombo—a community founded by escaped slaves—during construction of a condominium project in Bahia state. The environmental agency fined the firm about $18,000 in 2021 and ordered the river to be cleared, but residents still report loss of crops and trees due to the flooding.
MRV stated it follows all environmental regulations and invested over $65 million last year in sustainability projects. Menin’s office did not provide answers to specific queries.
The case highlights tensions between corporate sustainability claims and environmental accountability, especially as Brazil hosts a climate conference focused on global action.
