The choices made by consumers, corporations, and financiers in the Global North ripple across borders, often shaping the lives and environments of communities in the Global South. From sourcing raw materials to funding large-scale projects, some decisions result in exploitative practices, environmental degradation, and corruption in vulnerable regions. Journalism can play a critical role in unveiling these hidden connections by tracing supply chains and financial flows. The data and research team from the Pulitzer Center will share the techniques, data and tools they used to help journalists uncover the supply chains and financial enablers behind commodities and projects that contributed to environmental degradation and human rights abuse in the Global South. This session will dive into the reporting methodologies behind environmental investigations on rainforest and ocean issues that the team has conducted. The team will provide participants with an investigative framework and introduce them to both the open and private databases and tools used for such investigation. The purpose of this session is to allow participants to replicate the methodologies for their own investigations and to have practical guidelines to kickstart such investigations.
