The Critical Threshold: Approval of Methodologies by 2026
The Brazilian System of Emissions Trading (SBCE) has reached a decisive phase with the presentation, in May 2026, of the preliminary proposal for the sectoral scope by the Extraordinary Secretariat for the Carbon Market. According to what is documented by the Ministry of Finance, the first certification methodologies for carbon credits must be approved by the end of the year to ensure alignment with national and international strategic objectives.
The system is based on a critical threshold: companies that emit more than 25,000 tons of CO₂ equivalent per year will be included in the scheme, with an obligation to report starting from 10,000 tCO₂e. This threshold is not arbitrary: it represents the level at which industrial emissions begin to have a measurable impact on the buffering capacity of the Amazon rainforest system, which is already showing signs of structural degradation.
The Anthropogenic Pressure: From the Industrial Sector to Market Governance
The acceleration towards the Brazilian ETS is fueled by a combination of factors: the need to attract green investments, the desire to position green metals as an industrial competitive advantage, and international pressure for a system consistent with the goals of the Paris Agreement. As reported by Carbon Pulse in July 2026, the Brazilian government has advanced a roadmap that provides for the adoption of specific methodologies by the end of the year, with a view to integration with Mitigation Transfer Mechanisms (ITMOs).
The process is driven by a structural mechanism: the creation of the Extraordinary Secretariat for the Carbon Market, established in 2025 by presidential decree. This body not only coordinates the development of methodologies, but also establishes guidelines for the verification and certification of reduction projects, in line with the principles of the Brazilian System of Emissions Trading (SBCE) provided for by Law 15.042/2024.
The Ecosystemic Scope: Forests, Metals, and Global Markets
The effect of exceeding the critical threshold is not limited to the industrial sector. The buffering capacity of the Amazon rainforest — which has experienced an average decline of 18% in net primary productivity between 2015 and 2024, according to data from CMCC — is now subject to a new economic assessment. The SBCE system not only measures industrial emissions but also integrates the effect of agricultural and forestry activities through the certification of credits.
This new model has a direct impact on the resilience of the biological system: emission reduction projects must demonstrate consistency with local ecological conditions, avoiding over-certification. As documented by Fastmarkets in 2026, the government aims to transform steel and aluminum produced in Brazil into competitive export goods in the global market, based on a low-carbon certification that can be traded as ITMO.
The Intervention Window: Reversibility and Strategic Timeline
The approval of the first methodologies by the end of 2026 represents a critical window for Brazil. If not implemented, there is a risk of a structural delay in integrating with international carbon markets and attracting green financing. According to ICAP, full system operation is expected by 2031, but without a solid methodological basis by 2026, this date becomes unattainable.
The infrastructural cost of this change is not negligible: the creation of the system requires the implementation of a national registry for carbon credits, with traceability and verification requirements. Brazil has already set 2026 as the target for launching the platform, in line with what was announced by CarbonUnits.com in September 2025. The Impact KPI is clear: if the certification methodologies are not approved by the end of the year, the system’s ability to generate ITMO credits will be compromised.
Critical Indicator to Monitor
If you measure the number of approved certification methodologies by December 2026, you know that the threshold has been reached. If at least three operational proposals are not submitted for key sectors (steel, agriculture, energy), activate a process of national priority review and renegotiate the timeline with international authorities.
