The IAI provides financial support between $100,000 and $300,000 USD for research projects lasting up to 3 years, targeting teams from 14 specific Latin American and Caribbean countries. Funding is contingent on co-funding and alignment with IAI's strategic policies, including a mandatory equity, diversity, and inclusion (EDI) plan.

The proposal identifies a critical gap in Brazil's climate strategy where ocean-related projects are underrepresented despite the country's extensive coastline and the fact that 26.6% of its population lives in coastal zones. It argues that scientific knowledge is currently siloed and fails to reach policymakers and project designers. To address this, the project will leverage the Ministry of Science, Technology and Innovation's (MCTI) 'Science at Sea' program to create a science-based framework, engage stakeholders including the private sector, and develop a prioritized list of ocean-climate interventions. The ultimate goal is to produce at least one high-quality project concept note for submission to the Green Climate Fund, focusing on areas such as blue carbon, sea-level rise adaptation, and ocean-based renewable energy.

The waste sector is responsible for approximately 20% of human-driven methane emissions globally, primarily from the anaerobic breakdown of organic waste in landfills and dumps. With global waste generation projected to increase by 73% by 2050, the document argues that reducing methane is critical for slowing global warming and meeting Paris Agreement goals. It proposes a modified waste hierarchy focusing on food waste prevention, organic waste diversion (via composting and anaerobic digestion), and improved landfill design and dump rehabilitation. The brief highlights successful regional policies, such as South Korea's weight-based food waste collection and India's waste segregation rules, while noting that up to 60% of mitigation measures have low or negative costs.

The document examines four critical legal uncertainties hindering the implementation of the Brazilian Forest Code: the conflict between the Forest Code and the Atlantic Forest Law, the temporal benchmarks for Legal Reserve requirements under Article 68, the validity of revising previous environmental commitment terms, and the contradictory criteria for Environmental Reserve Quotas (CRA). These controversies create a state of permanent legal insecurity, leading to the suspension of CAR validations in states like Paraná and Santa Catarina, and a reliance on bureaucratic donation mechanisms for Legal Reserve compensation due to the lack of a functional CRA market.

The report identifies a critical lack of satisfactory federal legislation to resolve the overlap of Rural Environmental Registry (CAR) inscriptions on Indigenous Lands (TIs), noting that such overlaps are often used for land grabbing. It finds that most Brazilian states lack specific strategies for identifying and cancelling these irregular registrations, often relying on optional federal filters that only detect overlaps with fully homologated TIs, thereby leaving lands in the demarcation process vulnerable. The document analyzes state-level experiences—highlighting Pará as the only state with a specific cancellation strategy—and evaluates two pending bills (PL 4450/2021 and PL 486/2022) that aim to prohibit CAR inscriptions on public lands but still contain administrative gaps. It concludes with policy recommendations, including the need for the Ministry of Agriculture (MAPA) to revise Portaria 121/2021 and for Funai to maintain updated georeferenced data for all TIs to support fair and effective cancellation processes.

The analysis examines how the expansion of built-up areas at the expense of natural heat sinks like green spaces and water bodies increases urban heat risks in major cities across the Critical 9 countries. Using Copernicus Land Monitoring Service data and the IPCC's SSP1-1.9 scenario, the report details specific land-use losses in cities such as Shanghai, Karachi, and Dhaka, linking these changes to increased vulnerability to dangerous heat days (above 35°C) and rising energy demands for active cooling.

The study identifies fuel type, kitchen volume, cooking methods, and ventilation as the primary drivers of in-kitchen particulate matter exposure in low-income homes across 12 global cities. The highest concentrations were found in Dhaka, driven by small kitchen size and extensive frying, while the lowest were in Medellín. The research highlights that charcoal use significantly increases PM2.5 levels compared to natural gas or LPG, and that dual ventilation (mechanical and natural) is more effective at reducing pollutants than natural ventilation alone.

The document serves as a legislative annex listing the legal framework governing the Rural Environmental Registry (CAR) and the Environmental Regularization Program (PRA) in Brazil. It details federal laws, such as Law No. 12,651/2012, and specific state-level regulations for 23 Brazilian states and the Federal District, covering topics such as native vegetation protection, legal reserve compensation, and environmental licensing.

The report highlights the escalating risks of extreme heat on human health and productivity, noting that 356,000 people died from extreme heat in 2019. It argues that while cooling demand is expected to soar—with space-cooling units potentially reaching 2.5 billion by 2030—this must be managed through sustainable solutions to avoid tripling global electricity demand by 2050. The text advocates for a mix of passive cooling, nature-based solutions, and energy-efficient active cooling, supported by policies like Minimum Energy Performance Standards (MEPS) and the appointment of Chief Heat Officers in cities such as Athens and Miami Dade County.

The Guarantee Fund for Biogas (GFB) is designed as the first environmental guarantee fund in Brazil to unlock public and private credit for independent biogas developers who lack the collateral required by lenders. Structured as a CVM-compliant fixed-income fund investing in Brazilian treasury bills, the GFB will provide short-term collateral to enable loans during the construction phase of projects. A pilot phase targeting five Brazilian states aims to leverage USD 53 million in capital to enable USD 67 million in loans in the first year, with a 10-year goal of enabling USD 271 million in credit. The fund utilizes a blended finance structure with a 50% first-loss tranche for concessional investors to mitigate credit risk and lower fees for developers. If scaled and replicated to address 10% of Brazil's biogas potential, the instrument could enable USD 6.1 billion in loans and mitigate 7.8 million tons of CO2e annually.

The report examines rural credit in the Cerrado, noting that while the biome accounts for about one-third of Brazil's rural credit and agricultural production, financing is highly concentrated among large producers and public banks. It highlights a growing reliance on private funding sources like Agricultural Credit Notes (LCA) and a significant scarcity of credit for family farming through programs like PRONAF. The authors argue that improving credit access for smaller producers is essential for increasing productivity and reducing deforestation pressures.

The report examines rural credit in the Cerrado, noting that while the biome accounts for about one-third of Brazil's rural credit and agricultural production, financing is highly concentrated. Average contract values in the Cerrado are 181% higher than in other biomes, primarily benefiting large-scale soy and cattle producers. While there is a growing trend toward private funding sources like Agribusiness Credit Notes (LCA), public banks—specifically Banco do Brasil—continue to dominate distribution. The study highlights a significant gap in credit access for small and medium producers (Pronaf and Pronamp), arguing that improving this access is essential for increasing productivity and reducing deforestation pressures.

The report analyzes the legal landscape of mandatory forest replacement in Brazil, finding that only nine states have legislation fully aligned with current federal rules. It argues that most regulations still focus on raw material supply rather than biodiversity conservation, often allowing replacement areas to be significantly smaller than the suppressed areas. The authors recommend adopting 'no net loss' principles, ecological equivalence, and improved geospatial monitoring systems.

The report examines the transition of Ibama's environmental sanctioning process toward a model centered on environmental conciliation. It argues that while conciliation could theoretically speed up processes, its implementation under the current administration has been deficient due to regulatory delays, a lack of technical qualification in key appointments, and a dangerous centralization of power. These failures, combined with the replacement of career staff with political appointees, are found to weaken the deterrent effect of environmental fines and contribute to increased deforestation in the Amazon.

The report estimates that Brazil could significantly increase agricultural output without further deforestation by investing in farm equipment and operational costs, noting substantial regional variation in these requirements.

The document examines the health consequences of biomass burning in the Brazilian Amazon, highlighting the vulnerability of children, the elderly, and Indigenous populations. It notes that air quality standards in Brazil are less stringent than WHO guidelines and that monitoring systems have not been widely implemented. The brief links these fires to land clearing for agriculture and ranching, which contributes to climate change. It recommends a moratorium on deforestation, improved public health advisories, and international cooperation to meet Paris Agreement goals.

The document serves as a legislative annex, cataloging the federal laws, decrees, and normative instructions, as well as state-level regulations, that govern the Rural Environmental Registry (CAR) and the Environmental Regularization Program (PRA) in Brazil as of October 2021.

The report provides a detailed 'radiography' of the implementation of the Brazilian Forest Code in 2021. While CAR registration is advanced nationwide, the analysis and validation of these registries remain a critical bottleneck. Only a few states, such as Espírito Santo, have achieved high validation rates. The transition to the final stage—the Environmental Regularization Program (PRA)—is slow due to low producer interest and a lack of legal frameworks in several states. The report highlights the introduction of 'dynamic analysis' by the Brazilian Forest Service (SFB) as a potential accelerator and identifies significant legal uncertainties, particularly regarding the Atlantic Forest and the application of Article 68 of the Forest Code.

The 2021 snapshot of the Brazilian Forest Code implementation shows that while rural property registration (CAR) is well advanced nationwide, the subsequent analysis and validation stages remain significant bottlenecks. Only six states have fully operational Environmental Compliance Programs (PRA), and a group of states in the Northeast, Roraima, and Rio Grande do Sul continue to lag in legislation and implementation. Progress in 2021 included the incipient rollout of 'dynamic analysis' tools in five states and the regulation of the PRA in Amapá, Ceará, and Minas Gerais.

The report argues that a significant 'urban services divide' exists in the global South, where over 1.2 billion people lack reliable access to housing, water, sanitation, energy, and transport. This divide creates a cycle of poverty and environmental degradation. To break this cycle, the authors propose seven transformations: prioritizing the vulnerable in infrastructure design, partnering with alternative service providers, improving local data through community engagement, supporting informal workers, innovating financing and subsidies, promoting transparent land management, and creating diverse governance coalitions. The report emphasizes that these shifts can yield cascading economic and environmental benefits, including reduced GHG emissions and improved public health.
