Core Viewpoint - The effectiveness of REDD+ projects, aimed at reducing emissions from deforestation and degradation, has been questioned recently, leading to a decline in the value of carbon offsets [2][6]. Group 1: REDD+ Project Analysis - A study published in the journal Science analyzed 52 REDD+ projects across 12 countries in South America, Africa, and Southeast Asia, finding that only 19% of these projects met their self-reported emission reduction targets [3][6]. - The study indicates that while the climate benefits of REDD+ projects are higher than previous assessments, the overall effectiveness remains low, with significant regional variations in project success [6][7]. - The research highlights a concerning issue of "over-crediting," where the number of carbon credits issued exceeds the actual emissions reductions achieved [6][7]. Group 2: Recommendations for Improvement - To enhance the credibility and impact of forest carbon offsets, the study suggests improving baseline setting methods and strengthening verification frameworks [7]. - The findings emphasize that while many REDD+ projects are not as effective as claimed, some have achieved tangible results, particularly in Brazil and Africa [7].
