Alto Mayo carbon project

Supporting forests and people in Peru


The Alto Mayo project is a REDD+ (Reducing Emissions from Deforestation and forest Degradation) project protecting 182,000 hectares (450,000 acres) of Amazonian rainforest within the Alto Mayo Protected Forest in the San Martin region of Peru.


The forest saw high deforestation rates despite its protected status. Thanks to the project, between 2008 and 2020, deforestation in the Alto Mayo has declined by 59 percent, keeping 8.4 million metric tons of emissions from entering the atmosphere.

Theory of change

In response, a REDD+ project was established in partnership with the Peruvian national park agency (known by the acronym SERNANP in Spanish). The project sought to address the underlying drivers of forest clearance and to deliver positive benefits for local people and for the climate.

The project has reduced deforestation in part by brokering conservation agreements with local communities who agree to stop clearing forests in exchange for agricultural training, financial skills and access to specialty-grade coffee markets. To date, more than 1,300 such agreements have been signed in Alto Mayo — representing about 80 percent of the families living within the forest’s borders.

SERNANP, meanwhile, uses revenues from the sale of carbon credits from the project to employ forest rangers, improving enforcement and stopping illegal logging. Together, conservation agreements, agricultural training and forest monitoring are curbing deforestation — and the attendant climate-warming carbon emissions that it causes.


I am learning to help my family and to earn a better income and to make the biodiversity of the Alto Mayo Protected Forest better known. I am inspired by the love of nature and my children. Thanks to the support we receive I hope that in the future we will have our own micro-enterprise, because in the last few years we have improved a lot and we have a lot to offer.

Improved livelihoods

The Alto Mayo project has tangibly improved livelihoods in and around the project area. With many new settlers arriving in the area throughout the 2000s, the project has worked to facilitate their integration, opening up more than 500 sustainable job opportunities to date.

One notable area of improvement is coffee production. The project has provided routes by which families can prosper through farming coffee beans sustainably. To increase market access, the project supported the creation of a coffee cooperative known by its Spanish-language acronym, COOPBAM. In its first year of operation, COOPBAM exported 15,000 kilograms (33,000 pounds) of coffee beans that were certified and produced within the project area to Denmark.

Nature and biodiversity

The Peruvian Amazon is a biodiversity hotspot, and the Alto Mayo Protected Forest is no exception. More than 1,200 plants are native to the project area, as are numerous birds, mammals and reptiles. Of these, 25 are categorized as endangered by the International Union for the Conservation of Nature.

Thanks to the project’s investment in conservation enforcement, these species’ habitats are increasingly protected, providing them a chance to recover and preventing additional species from becoming endangered.

Environmental and agricultural education

In partnership with the SERNANP, the project is delivering environmental awareness and sustainable agriculture training for local people living in or near the project area.

With coffee production a significant driver of unsustainable land use, the project is focused on improving agricultural practices. Between 2018 and 2020, more than 2,800 people attended training classes on sustainable coffee production. Of these attendees, nearly a quarter (23.6 percent) were women.

Moreover, the project organizes environmental awareness classes in schools. With more than 80 sessions completed, at least 3,300 young people have participated in environmental awareness training.


Assurances in Alto Mayo

Human rights

In January 2023, serious allegations of improper destruction of properties within the project area were made. As a core principle of our work, Conservation International is deeply committed to protecting human rights. We considered this claim with the utmost care before concluding that it was based upon partial and incomplete information.

Regardless, we will be taking the additional due diligence step of hiring an outside expert to conduct an independent review of the Alto Mayo project and have pledged to publicly declare its findings.

In recognition of its effective climate mitigation and demonstrable benefits to local communities, the project’s activities have been approved by the Verified Carbon Standard and the Climate, Community and Biodiversity Standard since 2012. For example, in 2015, a repeat verification process used satellite imagery and on-the-ground interviews to measure the project’s continued impact.

REDD+ methodologies are continually improving, which means that some previously implemented methodologies no longer meet the high standards of the voluntary carbon market. Alto Mayo is committed to, and supportive of, REDD+ improvements and welcomes auditing, repeat verification and monitoring from independent third parties.

Peru is currently in the process of submitting its Forest Reference Emission Level (FREL). As a result, credit issuance is paused until the process is completed.


In the absence of the Alto Mayo project, deforestation inside the protected zone would have continued unabated. The project has slowed the rate of clearance by 59 percent, preventing an additional 8.4 million metric tons of emissions from entering the atmosphere. Furthermore, the carbon finance generated through the sale of carbon credits has helped resolve the drivers of deforestation in the Alto Mayo, making available new opportunities for local people to learn about sustainable agriculture that would not otherwise have been possible.


As with any REDD+ project, indefinite permanence cannot be guaranteed. The Alto Mayo Protected Forest remains vulnerable to fire — therefore, the project operates conservatively, taking clear measures to mitigate against risk. It currently retains 840,589 credits as a buffer pool to insure against the possibility of damage and loss. In this way, only a proportion of credits generated are ever issued, thus limiting the risk of over-crediting.


Sustainable Development Goals

The Alto Mayo project addresses the following goals (learn more about SDGs):



When we arrived in Alto Mayo, we did not know that we were in a protected area, or how to take care of it. Over time, the conservation agreements have opened many doors for us. It is as if we have been reborn. Now,I produce a high-quality coffee that protects the Alto Mayo Protected Forest and is enjoyed by the world. I have signed conservation agreements and thanks to this we have created COOPBAM [coffee growers’ co-op]. Thanks to fair trade we have better prices, and it has improved the quality of life of my family — and I can afford the education of my children.

Conservation at work in Alto Mayo

In the San Martin region of northern Peru, the Alto Mayo Protected Forest is home to many communities of coffee farmers who rely on the health of the land for their livelihoods. Through the Alto Mayo Conservation Initiative, CI and Peru’s National Service of National Protected Areas are engaging these farmers to protect the forest in exchange for benefits like sustainable farming workshops, health care access, and other benefits. With the support of Disney’s Climate Solutions Fund, CI is promoting sustainable coffee farming: methods that keep trees standing, lead to greater crop yields, generate better wages for the farmers, and protects biodiversity and water sources.
