Deep Dive: Exploring the Six Climate Projects
1. Macaúbas Waste-to-Energy Project (Brazil)
- Portfolio Share: 39.6%
- Project Type: Energy
- Geographic Focus: Brazil (Iron Quadrangle)
Context and Mechanism
Nestled in Brazil’s historic Iron Quadrangle—a region shaped by the legacy of the Gold Rush, rapid urbanization, and rich culinary traditions—the Macaúbas project tackles the hidden climate threat of municipal waste. As urban centers expanded, energy demands skyrocketed alongside organic waste generation.
The Macaúbas facility captures fugitive biogas (predominantly methane) produced by decomposing organic waste at the local landfill. Left unmanaged, methane escapes into the atmosphere, possessing a global warming potential significantly higher than carbon dioxide over a 20-year timeline. By capturing this gas and converting it into clean, renewable electricity, the project neutralizes a potent greenhouse gas.
Regional Benefits
Brazil’s national electrical grid relies heavily on hydroelectric power, making it increasingly vulnerable to shifting precipitation patterns driven by climate change. The Macaúbas Waste-to-Energy project supplies a reliable, weather-independent supplementary energy source. Furthermore, it fosters green employment opportunities and underpins sustainable regional economic development.
2. Sargassum Recovery for Clean Coasts (Mexico)
- Portfolio Share: 1.0%
- Project Type: Carbon Removal
- Geographic Focus: Mexico (Riviera Maya)
Context and Mechanism
Along the pristine shores of Mexico’s Riviera Maya, massive influxes of pelagic sargassum seaweed have become an ecological crisis. Driven by ocean warming and nutrient runoff, tidal waves of sargassum smother coral reefs, trap nesting sea turtles, and devastate local tourism economies. When left to rot on beaches, the decomposing seaweed emits toxic hydrogen sulfide gas and massive quantities of carbon dioxide.
This innovative initiative utilizes low-impact, manual and mechanical collection methods to remove sargassum from resort shorelines before decomposition sets in. The harvested biomass is then upcycled into high-value products, including agricultural biochar, nutrient-dense compost, and coastal erosion-control barriers.
Accolades and Recognition
Over the past year, the project’s blend of ecological restoration and technological innovation has earned international acclaim:
- Recognized as a Top Innovation Winner in the World Economic Forum’s Coastal Tourism Challenge.
- Awarded the prestigious Ocean Solution Label by the Sustainable Ocean Alliance.
- Honored as a finalist for the 2026 Unlocking the Planet Award.
Beyond carbon removal, the project supports women-led agricultural cooperatives that utilize the derived compost to grow organic produce, supplying sustainable farm-to-table ingredients directly to local hospitality menus.
3. Valle Paleazza Ecological Restoration (Italy)
- Portfolio Share: 5.8%
- Project Type: Blue/Teal Carbon
- Geographic Focus: Italy (Venice Lagoon)

Located within the iconic Venice Lagoon, the Valle Paleazza project restores centuries-old historic fishing valleys. By re-engineering traditional water management systems and executing targeted ecological restoration, the project revitalizes vital blue carbon habitats—submerged aquatic vegetation and salt marshes that sequester carbon at rates manifold higher than terrestrial forests.
Recent Developments (April–May 2026)
In April 2026, the project expanded its terrestrial-marine interface restoration by successfully planting 200 additional trees along the valley edges. Recognizing that sapling mortality is a primary challenge in restoration forestry, the field team maintains an intensive, year-round maintenance regimen. This includes scheduled watering regimens during dry periods, continuous health monitoring, swift replacement of struggling saplings, and active pest and disease management. These efforts ensure the long-term structural integrity and resilience of the lagoon’s transitional ecosystems.
4. Keo Seima Wildlife Sanctuary (Cambodia)
- Portfolio Share: 34.9%
- Project Type: Forests
- Geographic Focus: Cambodia
