The report finds that the air-conditioning sector in Brazil suffers from low energy efficiency compared to international standards, with a deterioration in both productive and energy efficiency between 2003 and 2015. Despite significant tax exemptions provided by the Zona Franca de Manaus (ZFM), which accounted for approximately R$ 285 million in 2015 for the AC sector, these incentives have not translated into improved efficiency or higher wages for workers. The authors argue that the Basic Productive Process (PPB) requirements, particularly those mandating the use of outdated national compressors, create distortions that hinder the adoption of modern technologies like inverter compressors and suppress competition. Consequently, rising sales of inefficient AC units, driven by heatwaves and increased income, have led to a 237% increase in residential electricity consumption for ACs between 2005 and 2017.

The report analyzes Brazil's agricultural risk management landscape, highlighting a significant gap in insurance coverage compared to global peers like the US and China. It examines key programs such as the PSR, Proagro, Garantia-Safra, and PGPM, noting high market concentration and a heavy reliance on credit over insurance. The authors argue that inadequate risk management leads to underinvestment and inefficient land use, recommending a shift in public funding from rural credit to insurance subsidies and the expansion of the Agricultural Climate Risk Zoning (ZARC) system.

The report examines Brazil's agricultural risk management landscape, focusing on public policies like PSR, PROAGRO, Garantia-Safra, and PGPM. It highlights a market characterized by high concentration, limited geographic reach, and a heavy reliance on soy insurance. The authors argue that inadequate risk management leads to underinvestment and inefficient land use, suggesting a shift in public funding from rural credit toward insurance and the expansion of market-based price risk instruments.

The document evaluates the impact of protected areas—including conservation units and indigenous lands—on deforestation in the Brazilian Amazon. It finds that while these areas effectively shield the forests within their boundaries, they often shift deforestation activities to unprotected regions, resulting in a negligible impact on total deforestation rates. The authors recommend integrating territorial protection with broader, coordinated conservation policies to prevent this displacement.

The document argues that environmental monitoring and enforcement focused on primary deforestation created a positive externality by deterring illegal activities more broadly, leading to increased natural regeneration in the Amazon. It highlights a critical gap in current monitoring systems (PRODES and DETER), which cannot detect secondary vegetation loss, and recommends that Brazil integrate tropical regeneration into its public policy agenda to enhance climate goals and ecosystem services.

A study by CPI/PUC-Rio found that environmental monitoring and law enforcement targeting illegal primary deforestation in the Brazilian Amazon from 2004 to 2014 created a positive 'spillover' effect, encouraging natural forest regrowth. The researchers argue that the perceived risk of punishment deterred illegal activities more broadly, leading offenders to abandon regions and allowing secondary vegetation to recover. However, current Brazilian monitoring systems, specifically PRODES and DETER, are designed to detect only primary vegetation loss, leaving secondary vegetation 'invisible' and vulnerable to deforestation. The brief recommends that Brazil adapt remote-sensing technology to monitor secondary vegetation and ensure law enforcement can penalize illegal secondary deforestation.

The report finds that despite significant tax exemptions, the industrial sector in the Zona Franca de Manaus (ZFM) shows no increase in productive or energy efficiency compared to the Brazilian national average. Analysis of the most representative sectors, including two-wheelers and audio/video, confirms that these incentives have not translated into comparative efficiency advantages.

The report analyzes how fossil fuel subsidies create direct and pass-through trade effects, distorting markets for crude energy products, refined energy carriers, and energy-intensive industries. It provides empirical evidence on the massive scale of these markets—with fossil fuel product trade alone representing over 10% of worldwide trade value in 2018—and argues that current WTO rules are ineffective at constraining these measures. The document proposes five options for WTO engagement: improving transparency, building capacity, establishing a pledge-and-review process, clarifying existing rules, and negotiating new binding subsidy disciplines.

The document argues that cattle productivity in Brazil is inversely related to the share of farmland devoted to pastures, meaning productivity increases as ranch size declines. It identifies land values as a key driver of this relationship, noting that higher land costs incentivize more intensive ranching or a switch to crop cultivation. The authors suggest that combating illegal deforestation, reducing agricultural modernization bottlenecks, and improving access to credit can drive cattle intensification and reduce pressure on forests.

The analysis of 14 large Swedish export-oriented businesses reveals that climate change is not viewed as a priority risk, with a lack of operational risk management strategies and a failure to link global climate change to specific supply chain operational risks.

The report finds that India's renewable energy power sector has historically been less risky and more lucrative than the fossil fuel sector, with higher risk-adjusted returns. Investor perceptions align with this, viewing renewables as safer, though solar is perceived as less risky than wind. The primary drivers of risk for both sectors are counterparty risk (specifically DISCOM non-payment), grid/transmission inadequacy, and financial sector constraints. Fossil fuel investments face additional significant risks from power market volatility and resource uncertainty, particularly for natural gas.

The policy brief analyzes the decentralized solar market in Brazil, finding that consumer uptake is driven primarily by demand-side factors rather than natural resource availability. Analysis of 5,563 municipalities reveals that areas with higher GDP, larger populations, and higher electricity tariffs have more photovoltaic units, while regions with the highest solar potential, such as the Center and Northeast, have lower adoption rates. The authors recommend that climate risk mitigation policies address these demand-side barriers to encourage solar penetration in the poorest regions with the highest solar potential.

An analysis of 5,563 Brazilian municipalities by the Climate Policy Initiative (CPI) and PUC-Rio reveals that distributed solar PV adoption is driven primarily by demand factors rather than natural resource availability. The study finds that municipalities with higher GDP, larger populations, and higher electricity tariffs have more PV units, while those with the highest solar radiation often have fewer. As of June 2017, only 1,478 municipalities had at least one distributed PV unit, with the highest concentration in Rio de Janeiro. The authors recommend that climate risk mitigation policies incorporate demand-side incentives and target poorer regions with high solar potential.

The research finds that demand-side factors are the primary drivers of distributed solar PV adoption in Brazil, often outweighing the availability of solar resources. Analysis shows that municipalities with higher GDP, larger populations, and higher electricity tariffs have more PV units, while solar radiation only becomes a significant positive predictor when comparing municipalities within the same electricity distributor's concession area. The authors argue that current subsidy policies in the Northeast region artificially lower tariffs, hindering PV growth in areas with the highest solar potential. They conclude that climate mitigation policies must address demand-side frictions and tariff structures rather than focusing solely on natural resource availability.

The paper finds that agricultural expansion in Matopiba is concentrated in the Cerrado biome, driven by technological innovations in soil management and soy varieties. This expansion led to significant increases in GDP per capita, particularly through direct agricultural growth and indirect spillovers into the services sector. While it improved access to durable consumer goods and electricity, it had no significant impact on migration or human capital investments.

This policy brief outlines how to use investment contracts to ensure large-scale agricultural projects in developing countries are sustainable and beneficial. It identifies five key positive outcomes—employment creation, integration of local farmers, expanded market opportunities, community development programs, and improved food security—and five primary downsides, including land loss, lack of community engagement, weak commercial viability, poor environmental/social management, and insufficient grievance mechanisms. The brief provides a framework for managing these factors across three stages: preparation, contract drafting, and monitoring and enforcement.

The document provides a comprehensive review of empirical studies demonstrating that compact, transit-oriented, and walkable urban design leads to lower greenhouse gas emissions, reduced infrastructure costs, and increased labor productivity. It highlights specific findings from China, such as the negative energy impacts of 'superblocks' in Jinan and the property value premiums associated with Bus Rapid Transit (BRT) in Beijing and Guangzhou. The report also emphasizes the cost-effectiveness of BRT over light rail and the public health benefits of non-motorized transit, while identifying research gaps in developer-side profit data and the specific productivity effects of density in Chinese cities.

The research analyzes wind power contracts under Brazil's PROINFA feed-in tariff scheme, finding that a nonlinear payment structure led wind farms to systematically misreport capacity factors (CFs). By comparing reported and realized CFs for 41 operational projects, the authors demonstrate that reported values clustered around price schedule cutoffs, while realized values did not. This misreporting resulted in wind farms being contracted for 14% more energy than delivered and 12% of first-year payments being over-payments. The paper concludes that a simple 1% interest rate penalty on overpayments would have effectively eliminated the incentive to misreport.

The report analyzes the cost-effectiveness of using infrared cameras for leak detection and repair (LDAR) programs in the oil and gas sector, based on data from over 4,000 surveys in North America.

The document examines the portrayal of vulnerability and the distribution of adaptation benefits in proposals approved by the Adaptation Fund Board up to December 2012. It argues that focusing on country-level allocation ignores the locally contextualized nature of vulnerability and seeks to provide lessons for the Green Climate Fund regarding the equitable and efficient allocation of scarce resources.
