This year, GIJN’s Resource Center team produced a wide variety of guides on everything from investigating climate change to reporting on AI, from digging into Chinese companies to probing evidence of war crimes, and from covering food insecurity to looking at land conflict. The Resource Center is full of material relevant for investigative reporters. The archive now holds more than 2,000 items in 14 languages — from tipsheets and guides to instructional videos. Here are our top selections for this year.

With fossil fuels accounting for more than 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions, GIJN recruited five top climate journalists to share their knowledge and expertise on how to enable better investigations of private and state-owned fossil fuel companies, how to uncover lobbying efforts that influence climate policies, and how to expose greenwashing and disinformation within the industry. The guide also touched on how to analyze government regulations and policies affecting the fossil fuel sector, and how to report on the climate solutions proposed by the fossil fuel industry.

Continuing a cutting-edge series of climate guides, GIJN advisor Toby McIntosh focused on the importance of investigating methane emissions from waste sites. This guide equips reporters who want to cover the climate and health impacts of methane from landfills, a major but overlooked source of greenhouse gas. It explains how to detect emissions using satellite data and on-the-ground reporting, offers key questions to evaluate mitigation measures, and highlights practical solutions — from biogas capture to composting — and real-world case studies. This resource helps journalists hold waste management systems accountable and elevate local reporting.

The number of people facing acute, life-threatening hunger nearly tripled in the last decade to 295 million across 53 countries, according to the 2025 Global Report on Food Crises. Conflict was the leading driver, followed by economic shocks and weather extremes. Yet food insecurity remains a challenging issue for journalists to investigate.

With their combined experience, award-winning journalists Thin Lei Win and Deborah Nelson put together a reporting guide to help journalists understand the causes of food inequity, famine, and starvation. They also break down technical terms and classification for journalists, pointing them to resources where they can find data and identifying areas that journalists can investigate further.

Scarcity of land in South Asian countries naturally leads to domestic conflicts between local communities, businesses, the political class, and the government when it comes to the use and ownership of land and its natural resources. These often escalate into conflicts that specifically affect marginalized communities, clog courts, and freeze big investments.

This guide helps journalists answer basic questions, such as: What is causing land resource conflicts? What is the scale of its impact? Who is impacted? Who are the actors involved and how do their motivations shape these conflicts? It also equips journalists with the tools and resources they need to report on land conflicts in a region that hosts nearly a quarter of the global population.

The guide features recent cases such as Azerbaijan’s “caviar diplomacy,” and secret lobbying on behalf of Qatar, and equips reporters with tools to expose hidden lobbying networks and hold power to account.

It provides background information on how caste shapes social, political, andfifani economic inequalities, especially in India. In addition, it outlines methods for gathering documentation, conducting interviews, and identifying systemic bias.

Covering social media algorithms can take many forms. Not only are algorithms on social media deeply complex, but the companies that produce them rarely disclose how they work. This guide helps journalists examine how opaque platform rules can shape misinformation, hate speech, and user experiences. It explains algorithm basics and media ecosystem dynamics, plus offers practical approaches — such as reverse engineering, content tracing, and experiments — to uncover harms. Featuring global case examples, the guide empowers reporters to hold social media companies accountable and reveal the impact of unseen algorithmic influence.

We’re approaching a point where the signal-to-noise ratio is getting close to one, meaning that as the pace of misinformation approaches that of factual information, it’s becoming nearly impossible to tell what’s real. In this guide, renowned trainer Henk Van Ess guides journalists through the process of identifying probable AI-generated content under deadline pressure, offering seven advanced detection categories that every online reporter needs to master. This was GIJN’s most popular guide for 2025.

As China emerges as a global superpower, with a population of 1.4 billion people and the world’s second-largest economy, Chinese corporate activities, government policies, and international investments directly impact stories across every beat. Despite a demand for reliable information, the landscape for international reporting from China has dramatically deteriorated in recent years.

This guide introduces journalists to open data needed for any China-related investigations, from public databases to government resources and corporate self-disclosures and legal and judicial documents. The guide provides insight into navigating the information ecosystem within China.

GIJN’s war crimes guide, originally published in 2023, now has three new chapters on prescient topics: the arms trade, forced displacement, and starvation. These chapters will assist journalists in investigating when an arms-exporting country is complicit in war crimes and crimes against humanity, when forced displacement can be prosecuted as an international crime, and when food is used as a weapon of war. The guide is also available as an e-book in multiple online bookstores.
