The document explains the mechanics of carbon credits, distinguishing between regulated markets under the Paris Agreement and voluntary markets. It highlights that while Latin America and the Caribbean accounted for 22% of global carbon credit sales in 2021, the region lacks the robust regulation needed to prevent environmental and social risks. The guide warns against over-reliance on the forestry sector, the risk of 'greenwashing' in voluntary markets, and the potential for 'double counting' of emission reductions. It recommends establishing transparent national registries, ensuring fair benefit-sharing with local communities, and prioritizing structural decarbonization over simple offsetting.

The technical appendices describe the use of a Global Trade Analysis Project (GTAP) general equilibrium model to simulate the effects of adopting the MyPlate and Harvard Healthy Eating Plate dietary guidelines. The analysis focuses on the resulting shifts in U.S. crop acreage, specifically the reduction of cereal grain production in favor of fruits, vegetables, and other crops. Key findings include a projected 8% decline in U.S. cereal grain acreage under the Harvard scenario and significant changes in land rental rates and production levels for various food sectors.

The report highlights that companies in Latin America and the Caribbean (LAC) achieve an average internal rate of return (IRR) of 17% on low-carbon investments, with energy efficiency projects specifically yielding 16.7%. It notes that the region's energy demand is 54% met by renewables and that LAC companies generate double the emission savings per dollar invested compared to those in the US. The document encourages the use of 'smart policies' such as cap-and-trade and renewable energy policies to further accelerate decarbonization.

The document examines coral reef recovery in Costa Rica's Caño Island Biological Reserve and Cocos Island National Park after severe bleaching events. Despite predictions of slow recovery, both protected areas show positive signs of recolonization, with Cocos Island seeing live coral cover increase from 3% in the 1980s to 23% in 2002. The authors suggest that designating reefs as protected no-take zones reduces localized human threats and enhances resilience to climate change.

The report introduces a quantitative methodology, first developed in 1988, that utilizes a dynamic land-use model to evaluate and compare the carbon sequestration potential of forestry projects. This approach was applied to assess carbon offset projects in Guatemala, Mexico, Nepal, Panama, and Thailand to provide practical guidance for policy-makers and project planners.

The research examines three Indigenous matrilineal communities—the Wayuu in Colombia, the Bribri in Costa Rica, and the Guna in Panama—to identify risks to women's land tenure resulting from climate actions. It finds that women face potential loss of land entitlements, disruption of livelihoods, and erosion of matrilineal culture, largely due to inadequate consultation processes and a failure to account for traditional gendered tenure systems. The paper argues that climate actions, such as wind park development, REDD+ negotiations, and climate-induced relocation, risk eroding customary rights and social support systems when they ignore differential tenure systems and power asymmetries.

Initiative 20x20 is a regional partnership in Latin America and the Caribbean designed to restore degraded landscapes through reforestation, agroforestry, and silvopasture. The initiative has surpassed its initial goal of 20 million hectares and has earmarked US$2.4 billion for project financing. The program addresses the fact that at least 200 million hectares of land in the region are severely degraded and that 49% of regional emissions stem from land-use change, forestry, and agriculture.

This World Resources Institute working paper reports on three workshops held in Asia, Africa, and Latin America to identify challenges developing countries face in monitoring and tracking climate finance. It details nine primary technical, political, and capacity barriers, ranging from inconsistent definitions and lack of institutional coordination to the limited transparency of development partners and the difficulty of tracking private financial data.
