Transparency International

To end corruption we must first understand it. That’s why we look at what causes corruption and what works against it.

At Transparency International, we have pioneered tools and methodologies to measure corruption as a vital first step to exposing and ultimately reducing it.

Our research team produces rigorous and independent assessments of corruption around the world. ➡️ Two examples of these tools are: 1️⃣ the Corruption Perceptions Index (CPI), which ranks countries and territories by their perceived levels of public sector corruption, according to experts and business people. 2️⃣ the Global Corruption Barometer (GCB), which complements the CPI by surveying ordinary citizens worldwide.

Throughout the years, we have been researching many different topics where corruption plays a key role: elections, money laundering, the climate crisis, gender, LGBTQ+, health or whistleblowing are some of those topics.

Our evidence collection supports our advocacy goals, emphasising political integrity and illicit money schemes, our global priorities. It helps us push for change at a global and international level.

🔴 The Corruption Perceptions Index 2025 revealed that over the past decade, most countries have made little to no progress in tackling public sector corruption.

The global order faces strain from major-power rivalry, armed conflicts, and the climate crisis. To address these challenges, we need principled leaders and strong institutions to act with integrity to protect the public interest.

200 million people depend on Pakistan's glaciers for water. For years, those glaciers were being cut apart and sold in local markets. In July 2024, Transparency International Pakistan (TI-P) filed a formal complaint to protect them. This is one of the 100 cases of climate corruption we have mapped worldwide.
