Créditos de Carbono na Amazônia

This report by the Climate Policy Initiative/PUC-Rio proposes a new economic-based methodology to evaluate the additionality of REDD (Reducing Emissions from Deforestation and Forest Degradation) carbon projects in the Brazilian Amazon. The study finds that while 77% of carbon traded in these projects is additional, significant regional variations exist, and some projects in isolated areas with low agricultural productivity lack additionality.

• A new methodology developed by CPI/PUC-Rio evaluates the additionality of REDD projects by integrating economic factors—such as agricultural prices, carbon prices, transport costs, and productivity—to determine the most profitable land use for private property owners in the Amazon.
• Analysis of current REDD projects in the Brazilian Amazon indicates that 77% of the carbon stock is additional, meaning these areas would likely have been deforested without the projects. This suggests the mechanism generally functions as an effective conservation tool, avoiding the emission of 0.5Gt of carbon equivalent.
• Additionality rates vary significantly across different regions of the Amazon biome: non-forest areas show the highest additionality at 98%, followed by deforested areas at 93%, forest areas at 79%, and areas under pressure at 72%.
• The municipality of Portel in Pará serves as a case study for low additionality; only 57% of the carbon stock in its REDD properties is additional because low agricultural productivity and high transport costs make deforestation economically unviable even without carbon credits.
• Properties most likely to have high additionality are those with larger areas, high agricultural productivity, lower carbon stocks, and lower transport costs, as these factors increase the risk of conversion to agriculture.
• The financial impact of non-additional credits is currently mitigated by the low price of REDD credits (between US$ 5 and US$ 15 per tCO2e) compared to the global average carbon price of US$ 35 per tCO2e. If REDD prices matched the global average, additionality would rise to over 86%.
