Avenue #4 Ancillary engagement This comprises corporate action that supports the first three avenues of action through indirect means, addresses systemic bottlenecks or involves capacity-building partnerships. Corporations can also take mangrove-positive action by enabling and improving mangrove conservation and restoration outside direct project development or their own supply chains. This can include investing in financial vehicles that are structured to fund mangrove-positive business models or relevant innovations, or financing intermediaries to structure projects and transactions. Companies may offer in- kind support such as technology for data sourcing, baselining and governance. Corporations can also provide ancillary support to generate carbon credits – for example, by investing in early-stage credit-generating projects prior to credit issuance, engaging in intermediary credit buying and supporting market liquidity through exchange platforms.97 CASE STUDY 4 Public-private collaboration in the Philippines protects biodiversity corridors In the Philippines, a recent Memorandum of Understanding between the Department of Environment and Natural Resources, Department of Energy and major private sector players, including Aboitiz Equity Ventures, San Miguel Corporation and Metro Pacific Investments, underscores the integration of financial strategies into environmental protection in the Verde Island Passage. The passage includes 1.14 million hectares of coral reef, mangrove and seagrass habitats and possesses a unique abundance of marine life. It provides livelihoods to millions of people through fishing and ecotourism, serves as a major commercial shipping channel and houses significant industrial complexes along part of its shoreline. Private corporations are committing substantial financial resources to achieve objectives such as establishing marine science research stations and transitioning to low-carbon development, which directly benefits mangroves and other coastal ecosystems. Additionally, the partnership emphasizes investment in inclusive platforms that improve the livelihoods of coastal communities. By protecting mangroves, which act as natural barriers and biodiversity hubs, the private sector is helping to secure the fisheries and tourism industries that many local economies depend on. These efforts ensure that economic gains from the Verde Island Passage’s resources are reinvested into conservation and community welfare, creating a cycle of sustainable financial support for the region.
