B20 & anti-corruption

B20-G20 dialogues on integrity and anti-corruption over the years, and how to enhance their effectiveness

The Business 20 (B20) represents the voice of business in the G20, an intergovernmental forum representing the world’s major economies. It acts as a platform for dialogue between businesses and the G20 presidency, which rotates each year, with input from civil society and international organisations.

As a multi-stakeholder forum for international economic cooperation, the B20 concentrates on topical high-priority issues that affect the stability and strength of the global economy and the ability of companies to compete on a level playing field.

Given the B20’s influence on both government policies and the private sector, it is crucial that issues of business ethics and integrity are central to B20 recommendations.

B20 Collective Action Key Performance Indicator: From Recommendation to measurable impact

Measuring Collective Action uptake at the G20 member country level

Collective Action has been one of the longest-standing recommendations of the B20. Under the Brazilian G20 Presidency in 2024, the development of a tailored and sustainable Key Performance Indicator (KPI) for Collective Action was prioritised as a legacy project. The KPI was co-developed and taken forward by the Basel Institute on Governance, drawing on the unique dataset of the B20 Collective Action Hub, which captures more than 350 Collective Action initiatives across the globe.

The introduction of a G20-level KPI provides a consistent basis for measuring the uptake of Collective Action across G20 member countries and creates a stronger evidence base for future B20 cycles to call on governments to engage with and support Collective Action initiatives as part of their business integrity efforts.

The KPI was subsequently also embedded in the B20 South Africa 2025 cycle, demonstrating its potential to provide continuity across successive B20 presidencies. The Basel Institute updates the KPI annually to maintain a consistent measurement framework and support a strong and united B20 voice on Collective Action.

For 2026, the KPI is being published again to maintain this continuity in the absence of a dedicated B20 Integrity & Compliance Task Force under the US B20 cycle. This ensures that Collective Action remains visible within the B20 process and that progress at the G20 member-country level can continue to be tracked using a consistent evidence base.

This open online resource is designed for policymakers and practitioners from any sector involved in B20-G20 anti-corruption dialogues. It provides:

  • Frequently asked questions on the B20 process and how different B20 presidencies have dealt with topics of integrity and anti-corruption.
  • Country pages with excerpts on anti-corruption from the official B20 policy documents and downloads of the original sources. The excerpts are particularly focused on Collective Action tools and approaches.
  • Recommended reading on the B20, G20 and anti-corruption.

We hope it will support the continuity and effectiveness of each new B20 cycle, giving stakeholders the information they need to understand past cycles and extract lessons learned.

About this resource

This resource is maintained by the Basel Institute on Governance. It was developed with funding from the Siemens Integrity Initiative following a mandate from the B20 in 2013 to develop a global resource centre on anti-corruption Collective Action.

The Basel Institute has actively contributed to the anti-corruption discussions of the B20 since its inception, generally with a formal role as Network and Knowledge Partner. Collective Action has been a reoccurring theme of these discussions and resulting recommendations. A specific milestone was the development of the Collective Action Key Performance Indicator under the 2024 B20 leadership in Brazil. The Basel Institute will continue to track performance against the indicator via the database.
