Landfill gas capture in Chile

Every £1 spent on this project has been verified to create at least £33 in environmental and social value. Mangrove planting contributes to all of these UN Sustainable Development Goals.


Project Summary

We are planting mangrove trees in Madagascar.

Mangrove trees are up to 5x more effective at carbon removal than UK tree species or other tropical forests.


We support local people with fair-wage work to plant and protect the trees.

Mangroves are up to 5x more effective at removing CO2 from the atmosphere versus UK tree species or other tropical forests. Through our planting and protection programmes, our reforestation efforts will sequester an average of 1.4 tons of carbon dioxide per acre annually.

This project was chosen as it has a huge impact on the climate both immediately and long term. The mangrove forests provide a crucial habitat that supports the local biodiversity and removes massive amounts of carbon from the atmosphere. This project meets the highest international standards and is regularly monitored and verified by independent third parties.


Mangrove forests are essential ecosystems whose dense roots serve as an anchor for the soil and coastline, preventing erosion and creating a barrier between harsh ocean systems and land. They also provide crucial habitats for numerous endangered species found nowhere else on earth. ​

  • Enormous carbon removal capability 

  • Native species. No monocultures.

  • Long-term sustainable planting practices

  • Comprehensive third-party verification

  • Significant social benefits

Benefits to local community

To ensure long-term success, reforestation projects must also benefit the local population.


Many of the people living in heavily deforested areas are living in extreme poverty. With few options to support their families, members of impoverished communities are forced to destroy their local environment to survive - such as cutting down trees for construction, fuel, heat, and agricultural purposes.


It is essential to work with local villages and communities to achieve a successful and longstanding reforestation programme. By employing local people to plant, care for, and protect the new forests we help prevent destructive practices and ensure the forests long-term survival and security.

The social benefits our mangrove planting project in Madagascar helps to provide include:

  • Steady and sustainable fair-wage income

  • Food, shelter, clothing, medicine

  • Access to education 

  • A route out of extreme poverty


How landfill gas capture works


Landfills generate methane as organic waste decomposes. Rather than getting released as emissions, that methane can be captured and used to produce electricity.


Over the course of a century, methane has 34 times the greenhouse effect of carbon dioxide. Landfills are a top source of methane emissions, releasing 12 percent of the world’s total. Landfill methane can be tapped, captured, and used as a fairly clean energy source for generating electricity or heat, rather than leaking into the air or being dispersed as waste.


The climate benefit is twofold: prevent landfill emissions and displace coal, oil, or natural gas that might otherwise be used.
