Healthy mangrove forest in the Indus Delta


Pakistan, Sindh
ClimatePartner ID: 1623
Blue carbon Get to know the project

Where the Indus flows into the Arabian Sea in south-eastern Pakistan, a complex web of river courses, streams and islands has emerged, providing a home to valuable mangrove forests with unique biodiversity. However, intensive agricultural use and soil salinisation have damaged the fragile ecosystem, preventing the mangrove forests from regenerating on their own. Therefore, this project will reforest a total of 224,997 hectares of mangrove forest and restore wetlands. The intact ecosystems will store about 2,407,620 tonnes of CO2 per year.

The project provides even further benefits: The mangrove forests effectively protect against storm surges and the inhabitants of the 60 villages nearby are sensitised to a sustainable use of the ecosystem. The mangroves also provide spawning grounds for fish and other marine life. For the special impact in the areas of climate, community and biodiversity, the project was awarded the gold level of the Climate, Community and Biodiversity Standards (CCBS).

How does blue carbon contribute to climate action?

Blue carbon refers to the CO2 emissions stored by marine and coastal ecosystems. Among others, mangrove trees are significant carbon reservoirs because they remove more greenhouse gas emissions from the atmosphere than terrestrial forests. Their special root system, which has semi-earthy and semi-marine components, collects biomass from organic matter, such as dead leaves and branches, over the years and binds CO2 emissions from the atmosphere. This particular root system stores far more CO2 than other tree species.

Worldwide, mangrove forests have been destroyed for agriculture or aquaculture, or cleared for timber and firewood. By damaging these enormous CO2 reservoirs, large amounts of CO2 are released again into the atmosphere. To avoid this, blue carbon projects protect mangrove forests and preserve coastal habitats for a variety of wildlife species - both in water and on land. The dense roots of mangroves also serve as natural protection against erosion, flooding and storms in coastal regions. Blue carbon projects in the ClimatePartner portfolio are registered with international standards.

The project aims to contribute to these United Nations’ Sustainable Development Goals (SDGs).

Project facts

Climate projects generally fall into one of three groups: carbon reduction, carbon removal, or carbon avoidance. Carbon reduction projects reduce the amount of greenhouse gas emissions produced by a specific activity (e.g., improved cookstoves). Carbon removal projects remove carbon from the atmosphere by sequestering it in carbon sinks (e.g., reforestation). Carbon avoidance projects avoid greenhouse gas emissions entering the atmosphere (e.g., protecting forests from deforestation with REDD+ projects).

All climate projects are based on international standards. They set processes and requirements which carbon projects must fulfill to be recognised as a proven method of reducing carbon emissions.

Climate projects demonstrably reduce, remove, or avoid greenhouse gas emissions. This is achieved with various technologies, ranging from nature-based solutions to social impact projects and renewable energies.

Climate projects go through third-party validation and verification. Verification happens regularly after each monitoring period. A validation and verification body checks and assesses whether the values and project activities stated in the monitoring report are correct and verifies them. As with validation, visits to the project site are often part of the process.

Climate projects go through third-party validation and verification. Validation happens early in the project life cycle and ensures that the project design is in line with current processes and requirements. This phase often also involves field visits with on-site interviews and analyses. Auditors are accredited, impartial assessors who have to be approved as a validation and verification body (VVB) by the standards body.

This figure shows the estimated annual emission reductions calculated before the project started. The actual number of emissions saved in each monitoring period may differ. The background to this process is that in order to be registered as a climate project, the project operator must submit the calculation of the estimated emissions savings using the ex-ante methodology in a Project Design Document (PDD), which is similar to a business plan. This calculation is validated by an independent auditor. The values determined in the PDD are recalculated during regular monitoring periods based on actual project performance, documented in a monitoring report, and verified again by independent auditors at the end of the monitoring period to ensure a robust process. Independent verification thus provides ex-post verification of actual emission reductions. Verified emission reductions are not distributed until the savings have actually been made.
