Brazil’s multi-protein future: smaller methane footprints, bigger markets

Climate Bonds analysis highlights how scaling the diversification dividend can make Brazil a multi-protein powerhouse and decouple its economic growth from methane emissions

Key highlights 

• Brazil is positioned to lead the next agricultural revolution by capturing new protein markets, rather than simply “cleaning up" the environmental legacy of the last one.  
• Brazil’s cattle sector is responsible for 71% of national methane emissions (around 416 Mt CO₂e per year) and improving beef production is a necessary short-term bridge to meet climate commitments. However, a diversified, multi-protein portfolio is the ultimate destination to future-proof Brazilian agribusiness.  
• Brazil’s cattle sector faces significant market, social and environmental risks which could result in up to 90% financial losses for most low-efficiency producers. The analysis explores 20 methane mitigation measures and identifies protein diversification and pasture optimisation as the two most strategic pathways for risk reduction and methane abatement.
• A 40% diversification into other proteins, like pork, poultry or plant-based, doubles the methane emissions reduction when compared to the best currently available intervention within the cattle-system. 

London, 26 February 2026, 9am — Climate Bonds Initiative has published a new report, 'Methane Abatement in Brazilian Cattle: Financial Opportunities and Challenges', supported by the Global Methane Hub, analysing how targeted investment can reduce methane emissions while strengthening economic resilience in one of the world’s most important agricultural markets. 

Brazil is home to the world’s second-largest cattle herd, and livestock production plays a central role in the national economy. At the same time, the sector accounts for approximately 71% of Brazil’s methane emissions, equivalent to around 416 Mt CO₂e per year, making it a critical focus for investors redirecting capital toward lower-emissions and nature-positive opportunities in emerging markets. 

Global market signals are shifting rapidly.  In a business-as-usual scenario, beef prices are projected to fall by 53% by 2050 compared to 2020 while financial institutions managing more than USD 121 trillion are increasingly screening portfolios and supply chains for deforestation and emissions risk. Without strategic diversification and optimisation, low-efficiency producers, particularly in North and Northeast Brazil, face growing financial, regulatory and reputational pressure. 
 

Investment pathways for methane abatement 

The report outlines three complementary pathways through which capital can drive methane reductions and support long-term resilience: 

1. Diversification away from cattle, including transitions towards poultry, pork, plant-based and alternative proteins, as well as reforestation. A 40% reduction in herd size could avoid up to 163.4 Mt CO₂e of methane per year by 2050. Plant-based and alternative proteins deliver near-total methane reductions, while poultry and pork offer 96–99% reductions using existing technologies and market demand. Reforestation further enhances carbon sequestration and biodiversity value.
2. Optimisation of pasture-based cattle systems, which represent 87-90% of Brazil’s herd. Improved forages, silvopastoral systems and better pasture management can deliver near-term methane reductions of up to 30% by 2030, while also improving soil health, water retention and farm incomes.
3. Direct methane abatement technologies, including feed additives, breeding improvements and manure management. These can reduce methane emissions by up to 30%, but their applicability is mostly limited to feedlot systems which account for only 10–13% of Brazil’s cattle herd – restricting their impact. 

The analysis underscores that absolute methane reductions ultimately require capping herd size, alongside efficiency gains and technological improvements. 

Investor relevance and Brazil’s strategic position 

Brazil is uniquely positioned to lead this transition. The country combines vast areas of degraded pastureland, strong agricultural research institutions, established poultry and soy infrastructure, and globally significant natural capital, creating opportunities to link methane mitigation with nature-positive strategies, biodiversity finance and carbon markets. 

Reyes Tirado, Global Lead for Agrifood at Climate Bonds Initiative, said: 

“For international investors, Brazil’s cattle sector represents a critical junction of material climate risk and significant transition opportunity. This report identifies exactly where capital can play a catalytic role. While immediate methane reductions can be achieved through pasture optimisation, the long-term shift toward multi-protein portfolios offers a powerful, yet untapped, path to resilience. By embracing these strategies, investors can mitigate regulatory exposure and unlock new sources of value.” 

The report sets out clear recommendations for investors, including integrating methane metrics into ESG frameworks, supporting a dual-track transition that combines short-term optimisation with long-term diversification, prioritising nature-positive investments, and backing high-impact innovation such as alternative proteins and genetic improvements.
