The Brazilian government launched Plano Clima with the goal of reducing greenhouse gas emissions by 59% to 67% by 2035, compared with 2005 levels, with a long-term target of climate neutrality by 2050. For 2026, the Climate Fund will make more than R$33 billion available, including R$27.5 billion in reimbursable resources through BNDES. The plan covers eight sectors, including energy and waste, and identifies biogas, biomethane, and sanitation with energy generation as critical drivers of decarbonization. For investors and sector players, the plan represents both a real window of opportunity and a set of risks that must be closely monitored.
When the federal government officially launched Plano Clima in March 2026, consolidating a process that had begun two years earlier, the document arrived with significant expectations and numbers the energy sector cannot afford to ignore. The plan’s main target is to reduce carbon dioxide emissions by 59% to 67% by 2035, based on 2005 levels, with the goal of reaching climate neutrality by 2050. Agência Brasil
This is no longer just a statement of intent. The plan’s development began in 2023, involved the participation of 24,000 people, and resulted in around 5,000 proposals, which were synthesized and selected by the Interministerial Committee on Climate Change, made up of 25 ministries. The practical result is a sector-based decarbonization roadmap that indicates where public and private resources are expected to flow in the coming years. Agência Brasil
For the clean energy sector, especially for biogas, biomethane, and waste-to-energy projects, Plano Clima represents something rarely seen so clearly in Brazil: a public policy signal backed by significant budget allocation and aligned with the climate targets of the Paris Agreement.
The Scale of the Targets: What Brazil Has Promised the World
Under Brazil’s NDC, the country has committed to emitting, by 2035, no more than between 1.05 billion and 850 million tons of CO₂ equivalent, a reduction of 59% to 67% compared with 2005 levels. To understand the scale of the challenge, it is enough to look at the starting point: national emissions recorded in 2022 totaled 2.04 billion tons of CO₂ equivalent. Cutting this volume in half in just over a decade requires far more than regulation. It requires capital allocated with intelligence and speed. Agência GovOlhar Digital
Plano Clima was structured as a complement to the NDC submitted by Brazil to the Secretariat of the United Nations Framework Convention on Climate Change in November 2024, serving as a roadmap for achieving the 59% to 67% emissions reduction by 2035. Agência Brasil
The plan is structured around two major pillars: the first addresses emissions reduction through the National Mitigation Strategy, with eight sectoral agendas; the second is the National Adaptation Strategy, composed of 16 agendas focused on preparing the country for the impacts of global warming.

The eight mitigation sectors are energy, industry, transportation, agriculture and livestock, land use in public areas, land use in private rural areas, cities, and, most strategically for those working with waste: sanitation and solid waste.
Money on the Table: The Climate Fund and the R$33 Billion for 2026
Targets without financing are just rhetoric. What sets Plano Clima apart from previous initiatives is the volume of resources mobilized to support it. For 2026, the Climate Fund will have more than R$33 billion available, most of it in reimbursable resources through BNDES, totaling around R$27.5 billion. Agência Brasil
The fund’s growth in recent years has been significant. The Climate Fund, created in 2009, grew from an average annual amount of R$400 million between 2010 and 2024 to more than R$10 billion in annual budget in 2024 and 2025. The projection is to exceed R$48 billion in reimbursable budget over the 2024 to 2026 period. GOV.BRGOV.BR
One of the new developments in 2026, however, deserves critical attention from investors: 73% of the available resources come from oil, through the Oil Social Fund, surpassing for the first time the resources raised through green bonds issued by the National Treasury, which account for 26% of the total. There is a political component to this composition that, from the standpoint of the long-term sustainability of financing, is something the market needs to monitor. Politicaporinteiro
Energy transition projects account for more than half of private-sector demand for Climate Fund resources, due to the level of maturity they have already reached. This means that a pipeline of eligible projects exists. Historically, the bottleneck has been the availability of resources, and 2026 signals that this constraint is being addressed seriously. GOV.BR
Energy in Plano Clima: Bioenergy, Efficiency, and Industrial Decarbonization
Brazil’s energy sector stands out internationally for its largely renewable matrix, with 47.2% of domestic energy supply coming from clean sources in 2022. Even so, it accounts for around 20% of national emissions. Portal
The energy sector plan proposes a set of measures that includes expanding bioenergy, strengthening energy efficiency, modernizing electrical infrastructure, and reducing the use of fossil fuels. Bioenergy, which includes biogas and biomethane produced from organic waste, appears as one of the central decarbonization drivers in the sector.
This is not a bet made in a vacuum. BNDES has already been signaling this direction through concrete approvals. In 2026, during COP30, results were presented from public calls for climate mitigation that attracted 45 fund proposals, with an aggregate value of approximately R$73.7 billion in private capital seeking allocation in sectors such as energy transition and industrial decarbonization.
Waste and Biogas: The Opportunity Plano Clima Cannot Afford to Waste
The waste sector is one of the most critical, and also one of the most promising, within Plano Clima. The sector accounts for around 15% of national methane emissions, one of the most powerful greenhouse gases in terms of global warming potential, with 85 MtCO₂e emitted in 2022, mainly due to waste disposal in dumps and inefficient sewage treatment. Portal
The plan includes the closure of dumps, the expansion of selective waste collection, the energy recovery of biogas, and the improvement of wastewater treatment plants. Replacing outdated technologies with higher-efficiency systems is considered essential, as is the safe management of sewage sludge. Portal
For the private sector, this combination of regulation, financing, and demand creates a concrete business window. Companies operating in the biogas and biomethane chain, such as those running biodigestion plants for agro-industrial or urban waste, find in Plano Clima a public policy framework that turns technical feasibility into economic feasibility.
The Climate Fund already proves this dynamic in practice. Biomethane projects using sugarcane waste, landfill waste, and animal protein waste have already been approved with significant financing through BNDES, demonstrating that demand for capital exists and that projects are mature enough for structured fundraising.
Eva Energia, for example, operates precisely at the intersection between clean energy and the use of energy-generating waste, a segment that benefits directly from this regulatory and financial environment.
Sanitation as an Energy Driver: The Still-Unresolved Equation
The National Secretary for Climate Change identified sanitation as one of the three most challenging sectors within Plano Clima. Brazil has a target of universalizing basic sanitation, and sewage treatment produces biogas as a natural byproduct of anaerobic digestion. This means that every new wastewater treatment plant built or modernized is, potentially, a renewable energy plant.
The problem is that, despite the potential, the integration between sanitation and energy generation is still incipient in Brazil. Public spending allocated to basic sanitation, directly related to emissions from waste, remains limited within the 2026 climate budget. There is a gap between what Plano Clima sets as a target and what the federal budget effectively prioritizes in this segment. Politicaporinteiro
For attentive investors, this gap may represent an opportunity for structured private participation through public-private partnerships and concessions that make sanitation infrastructure viable with embedded energy generation.
Risks Investors Need to Monitor
Plano Clima is not an instrument without vulnerabilities. Civil society organizations point out that the energy and industry sector plans do not provide sufficient detail on reducing the use of fossil fuels, which could compromise the long-term decarbonization commitment. Olhar Digital
Political risk is another point of attention. There is a risk of discontinuity in the event of changes in the political landscape after the 2026 elections, since there is no specific law institutionalizing Plano Clima. On the other hand, many of the policies included in the plan are already linked to their own legislation, and the Paris Agreement is recognized by Brazil’s Supreme Federal Court as a supralegal norm. Olhar DigitalOlhar Digital
There are also questions about the total cost of implementing the plan, which has not yet been published in consolidated form. Without clarity on the total volume of investment required, it is difficult for the market to calibrate the relationship between public capital supply and private capital demand.
Finally, the geographic concentration of financed projects needs to be overcome. Historically, climate finance in Brazil and worldwide tends to flow toward regions with greater technical capacity to structure projects, leaving out areas with high potential for biogas and biomethane generation, especially in the country’s interior.
Conclusion
Plano Clima arrived late, went through tense negotiations, and still presents gaps that need to be filled. But it exists, it has numbers, it has a sectoral structure, and it has financial allocation. For the clean energy sector, especially for those working with biogas, biomethane, waste recovery, and sanitation with energy generation, the outlook from 2026 onward is the most favorable ever built by the Brazilian government in this area.
There is no such thing as zero risk in public policy. But investors who understand the conditions created by Plano Clima, monitor Climate Fund credit lines through BNDES, and position mature projects within this context will have access to the largest volume of climate financing ever mobilized in the country. The window is open. The question is who will cross it with real projects.
