In this paper, the World Economic Forum’s Giving to Amplify Earth Action (GAEA) initiative, in partnership with McKinsey & Company, promotes public-private-philanthropic collaborations or “4P models” to address climate and nature challenges. These models require diverse stakeholders and the alignment of goals to make use of their unique strengths.

To achieve the Paris Agreement’s goals, collaborative action on a global scale is crucial. Four years into the UN's “Decade of Action”, challenges like rising carbon emissions and loss of natural systems persist. To achieve the Paris Agreement’s goals, collaborative action on a global scale is crucial.

This paper identifies solution areas for 4P models using three pillars: materiality, suitability and feasibility. Over 50 established 4P models show potential but face challenges in scaling. To enhance effectiveness, the paper suggests five strategies, such as establishing anchor stakeholders and capitalizing on existing models. Such collaborations can significantly address global issues, ensuring a balanced approach to global challenges.
