Designed to deliver measurable ecological and societal benefits, the latest portfolio addresses critical environmental challenges by mitigating greenhouse gas emissions, protecting fragile biodiversity, and uplifting local communities.

The carbon offsets purchased through this latest portfolio distribution are thoughtfully allocated across a diverse mix of project methodologies. These include forestry initiatives, renewable energy generation, blue and teal carbon ecosystem restoration, and innovative carbon removal technologies. By blending these diverse approaches, the portfolio provides a comprehensive mechanism for accelerating the global transition toward a net-zero future while fostering resilience in vulnerable ecosystems.

Impact in Numbers

Altogether, the six projects featured in the first portfolio of 2026 are actively accelerating the global net-zero transition through several remarkable milestones on the ground. Through forestry protection initiatives, the portfolio successfully prevents the loss of 1,060,000 acres of carbon-rich forests. In the energy sector, participating projects generate 78.7 gigawatt-hours (GWh) of renewable energy on an annual basis, providing vital supplementary power to grids facing climate-induced strain.

Furthermore, the portfolio addresses localized waste management and marine health by diverting up to 1,440 cubic meters of sargassum and green waste from traditional landfills every week. Alongside these waste-to-energy and upcycling efforts, the initiative is deeply committed to marine and coastal restoration. Through dedicated conservation measures, the portfolio successfully protects and restores 91,317 acres of vital blue and teal carbon ecosystems, ensuring that critical coastal habitats continue to sequester carbon effectively for generations to come.

Explore the Projects

The first Climate Impact Portfolio of 2026 is composed of six meticulously vetted climate projects: the Macaúbas Waste-to-Energy project, the Sargassum Recovery for Clean Coasts initiative, the Valle Paleazza restoration effort, the Keo Seima Wildlife Sanctuary, the Yaeda-Eyasi Landscape Project, and the Rimba Raya Biodiversity Reserve. Each of these initiatives plays a unique role in catalyzing localized climate action while addressing the complex socio-economic realities of the regions in which they operate.

Macaúbas Waste-to-Energy (Brazil)

Representing 39.6% of the overall portfolio allocation, the Macaúbas Waste-to-Energy project is centered in Brazil’s historic Iron Quadrangle. This region, shaped by the historical legacy of the Gold Rush, experienced rapid urbanization and population growth that fostered vibrant cities and rich culinary traditions. However, this growth also drove a steep rise in energy demand and municipal waste generation.

The project operates by capturing biogas produced from decomposing organic waste at the Macaúbas landfill. By intercepting this gas, the initiative prevents potent methane emissions from escaping directly into the atmosphere, instead converting the captured gas into clean, renewable electricity. This process provides a reliable supplementary energy source at a crucial time, as Brazil’s traditional river-powered hydroelectric grid faces increasing operational strain from shifting weather patterns and climate change. Beyond its direct atmospheric benefits, the project stimulates green jobs and promotes sustainable economic development within the local community.

Sargassum Recovery for Clean Coasts (Mexico)

Accounting for 1.0% of the portfolio, the Sargassum Recovery initiative addresses the overwhelming influx of sargassum seaweed that continuously threatens coral reefs, nesting sea turtles, and the vital tourism economy along Mexico’s Riviera Maya coastline. Utilizing low-impact manual and mechanical collection methods, the project removes accumulating sargassum from resort shorelines. This intervention significantly improves nearshore marine health, restores the pristine aesthetic appeal of the beaches, and stops the massive emissions of toxic gases that typically occur when the seaweed rots in unmanaged piles.

Once collected, the seaweed is upcycled into valuable materials, including biochar, high-grade agricultural compost, and specialized shoreline protection products. This circular economy model creates meaningful local employment and supports women-led farming cooperatives that supply sustainably grown, organic ingredients directly to local hotel culinary teams.

Over the past year, the initiative has secured prestigious international recognition for its commitment to biodiversity and marine innovation. Notably, it was named a Top Innovation Winner in the World Economic Forum’s Coastal Tourism Challenge. Reinforcing its scientific and environmental credibility, the project was also awarded the Ocean Solution Label by the Sustainable Ocean Alliance and was recently honored as a finalist for the 2026 Unlocking the Planet Award. These accolades highlight the project’s vital role in advancing climate resilience and fostering sustainable livelihoods within coastal communities.

Valle Paleazza (Italy)

Comprising 5.8% of the portfolio, the Valle Paleazza project focuses on the restoration of centuries-old fishing valleys located within the iconic Venice Lagoon. By reviving traditional water management techniques alongside modern ecological restoration science, the project revitalizes crucial blue and teal carbon habitats. This dual approach effectively removes carbon dioxide from the atmosphere while re-establishing thriving fish nurseries and expansive bird nesting grounds.

In addition to its climate and biodiversity benefits, the restoration supports small-scale local fishing and aquaculture livelihoods, while simultaneously opening up new pathways for responsible, nature-based tourism. Furthermore, the restored wetland acting as a natural buffer helps reduce coastal erosion and flooding, thereby increasing the physical and economic resilience of low-lying human communities facing the compounding threats of sea-level rise and climate change.

The project team has maintained an active operational schedule. In April, staff continued their extensive tree-planting campaign in Valle Palleazza, successfully planting 200 additional trees along the historic valleys. This planting effort is paired with a rigorous, ongoing maintenance program designed to ensure that every new sapling survives and thrives. The regimen includes regular watering during dry seasonal periods, continuous monitoring of plant health, and the replacement of any specimens that fail to establish themselves.

Field teams also conduct periodic checks to manage potential pests and diseases, clear competing invasive vegetation, and maintain optimal soil conditions, providing mechanical structural support where necessary. Through these diligent upkeep measures, the project team guarantees that both existing mature trees and newly established vegetation remain robust and resilient against environmental stressors.

Keo Seima Wildlife Sanctuary (Cambodia)

Making up 34.9% of the portfolio, the Keo Seima project protects a sprawling tropical forest sanctuary in Cambodia that holds immense cultural, spiritual, and economic significance for the Indigenous Bunong people. The project successfully curtails carbon emissions from deforestation by safeguarding the landscape from unsustainable agricultural conversion and illegal commercial logging. At the same time, it addresses the underlying socio-economic drivers of deforestation, such as rural poverty and food insecurity, which often force local families into extractive and destructive practices.

Along with preserving rare tree species found nowhere else in the world, the sanctuary acts as an impenetrable barrier against wildlife trafficking, providing a safe and protected refuge for endangered fauna, including the striking yellow-cheeked gibbon.

The project has achieved significant strides in strengthening local governance and community resilience through collaborative initiatives. By facilitating structured focus group discussions and providing specialized leadership training, project organizers have ensured that forest protection efforts in Cheung Phnum Beng and Karamash remain firmly rooted in Indigenous leadership and transparent, community-led management. This deep commitment to grassroots empowerment extends directly to frontline safety. In recent months, intensive first-aid training was delivered in partnership with the Cambodian Red Cross to prepare local patrol teams for medical emergencies encountered during remote forest patrols.

Beyond governance and safety, the initiative actively fosters a profound connection between active conservation and cultural preservation. The recent construction of traditional Bunong houses within the sanctuary serves as a vital physical anchor for Indigenous architectural heritage. Simultaneously, the collaborative "Green Sprouts" campaign encourages the wider community to take personal responsibility for local reforestation efforts. By weaving these cultural landmarks together with active environmental stewardship, the project champions a holistic model that protects both the natural landscape and the identity of its traditional guardians.

Yaeda-Eyasi Landscape Project (Tanzania)

Representing 4.7% of the portfolio, the Yaeda-Eyasi Landscape Project assists Tanzania’s Indigenous communities in safeguarding their ancestral natural resources and preventing their fragile dryland forests from being converted into commercial cropland by outside encroachers. By focusing centrally on the preservation of their forested homeland and nomadic or semi-nomadic lifestyles, the project provides communities with a reliable, sustainable income stream derived from carbon finance. These funds are then channeled directly into community-managed social initiatives that dramatically improve local access to essential education and healthcare services.

The project is currently undergoing a rigorous five-year verification process conducted by independent expert auditors under the Plan Vivo Standard. This exhaustive evaluation ensures that all reported carbon savings are genuine, transparent, and rigorously measurable on the ground. As part of this comprehensive review, the project is updating its baseline carbon accounting using the most advanced scientific methodologies available. Furthermore, a specialized biodiversity monitoring program has been introduced, utilizing native bird species as biological indicators to track overall ecosystem health and stability across the landscape.

This transition period is also being utilized to reinforce how the project engages with local communities. Organizers are actively refining their Free, Prior, and Informed Consent (FPIC) protocols and social assessment frameworks to surpass standard industry requirements. These enhancements ensure that community members remain fully informed, actively involved, and possess a decisive voice in all governance and land-use decisions across the Yaeda-Eyasi region.

Rimba Raya Biodiversity Reserve (Indonesia)

Rounding out the portfolio with a 14.0% allocation, the Rimba Raya Biodiversity Reserve is dedicated to conserving a massive, carbon-rich peat swamp forest in Indonesian Borneo that was previously slated for commercial conversion into industrial palm oil plantations. Alongside its primary mission of keeping millions of tons of carbon locked safely within the peat soils and dense vegetation, the project provides direct support for the rescue, rehabilitation, and reintroduction of critically endangered orangutans back into their native wild habitat. By directly tackling systemic challenges such as rural poverty, food scarcity, and limited healthcare access, Rimba Raya addresses the root causes of regional deforestation while simultaneously uplifting the standard of living for neighboring human communities.
