It brings together an interdisciplinary team of political and natural ecologists and ecosystem modelers and aims to comprehensively assess the quality of REDD+ carbon credits when it comes to reducing deforestation, generating high-quality carbon credits and protecting forest communities.
REDD+ (Reducing Emissions from Deforestation and Forest Degradation) is the project type with the most credits on the voluntary carbon market, accounting for about a quarter of all credits to date. The study focuses on five key programme elements: baselines, leakage, forest carbon accounting, durability and safeguards.
The researchers found that estimates of emissions reductions were exaggerated across all quantification factors they reviewed when compared to the published literature and an independent quantitative project assessment. They say: “As a result, current REDD+ methodologies likely generate credits that represent a small fraction of their claimed climate benefit. Safeguard policies, presented as ensuring “no net harm” to forest communities, in practice have been treated as voluntary guidance.”
While many studies have documented poor carbon offset quality, the new analysis goes a step further in exploring the underlying reasons credit quality is poor. In some cases, the researchers say the methodologies did not align with good practice. Moreover, when the requirements were vague or flexible, they found that developers commonly made methodological choices that led to more credits and the auditors commonly did not enforce conservativeness, accuracy and “even reasonableness”.
Their overall conclusion is that REDD+ is ill-suited to the generation of carbon credits for use as offsets. They suggest a number of other actions that private actors can take or support that together can help to reduce tropical deforestation.
What is good technology? Is ‘good’ technology even possible? And how can feminism contribute towards it? Those questions and more are at the heart of a new book co-edited by Gates Cambridge Scholar Dr Kerry McInerney and based on the popular podcast series she co-hosts. The Good Robot: Why technology needs feminism gathers together the thoughts of leading […]
The summer before starting his PhD at the University of Cambridge, Rob Henderson was working up a book proposal with his literary agent. That book, Troubled, is published next month by Simon & Schuster and is part memoir, part social commentary. In it Rob recounts his life growing up in foster care and his time […]
A Gates Cambridge Scholar is organising a webinar to publicise the formal launch of a public, online information hub on the intersection between climate change and mental health. Colleen Rollins , editorial and project manager at the Climate Psychiatry Alliance, is working on the Ecopsychepedia (“EcoPsy”) project which will be the subject of a webinar […]
When José Izquierdo  was working on his PhD at Cambridge on how Latin American composers united European and local influences in the 19th century, he found a way to make his academic work come to life. Much of the music he was researching had never been heard before and he was also discovering old scores […]
