About us
Origins, purpose and future
We were founded on a shared set of values and a commitment to providing environmental and legal solutions that are both people-centred and, at the same time, effective, thereby maximising the positive contribution that companies make to society, people and the environment.
We are based in Belém, Pará – the capital of the Amazon and host city of COP 30 – and in São Paulo, São Paulo state – the business hub of Latin America – and we serve clients across various regions of Brazil, ready to handle medium- and large-volume cases of varying degrees of complexity.
We operate supported by an interconnected and ongoing network of partners with expertise in environmental and regulatory matters across various regions of Brazil. Our teams are tailor-made for each specific requirement. This enables us to utilise human resources intelligently and offer optimised legal solutions at competitive rates.
