About Carbonext
Carbonext operates as a key developer of nature-based solutions to address climate change, primarily focusing on generating carbon credits through forest preservation projects in the Amazon. Founded in 2010 by Janaina Dallan, a forestry engineer with extensive experience in the European carbon market, the company has established itself as a significant player in Brazil's environmental services sector. Dallan's deep expertise in carbon projects, including her work with the UN, has been foundational to the company's trajectory.
In 2021, Luciano Corrêa da Fonseca, an economist with a background in private equity at Pátria Investimentos and brother of the founder, joined as co-CEO. His financial acumen facilitated two major investment rounds, significantly accelerating the company's growth and diversification. A pivotal milestone occurred in July 2022, when Carbonext secured a R$ 200 million (approximately USD 40 million) investment from Shell Brasil, which acquired a minority stake in the company. This funding was earmarked for expanding project development, investing in technology, and exploring new business areas like bioeconomy and reforestation.
The company's core business involves developing projects that reduce emissions from deforestation and forest degradation (REDD+), generating carbon credits that are then sold to corporate clients seeking to offset their greenhouse gas emissions. Carbonext manages the entire project lifecycle, from identifying land and negotiating with landowners to handling the complex certification process required to issue credits. Its client base includes major corporations such as Shell, Uber, TIM, and C6 Bank. Revenue is generated from the sale of these carbon credits and providing decarbonization strategy services.
Carbonext offers a suite of services for different client types. For companies, it provides GHG emissions inventories, develops customized decarbonization strategies using methodologies like the Science Based Targets initiative (SBTi), and offers carbon credits for offsetting residual emissions. For landowners in the Amazon, Carbonext forms partnerships to develop REDD+, Afforestation, Reforestation, and Revegetation (ARR), and Agricultural Land Management (ALM) projects, turning forest conservation into a new income stream. These projects also aim to deliver socioeconomic benefits to local communities. The company has also expanded its technological capabilities through a 40% acquisition of Mangue Tech, a platform that automates the carbon footprint calculation for businesses.
