The conference was hosted by Transparency International, the Brazilian Office of the Comptroller General, Amarribo Brasil and Instituto Ethos. With more than 1900 representatives from the public, private and non-profit sector from 140 countries, the conference functioned as an important platform to discuss best practices, trends and developments in the fight against corruption. The Brazilian President Dilma Rousseff opened the conference by presenting the government´s effort in promoting public and private ethics, public transparency, open government and citizen participation. She introduced five global challenges that opened up debate on ending impunity, clean climate governance, political transitions leading to stable and transparency governments, clean sports and preventing illicit financial flows. On the latter, Spanish judge Baltasar Garzón highlighted in a plenary session the importance of agreeing on an EU system to combat the diversion of money to offshore territories and tax havens. Blomeyer & Sanz is currently reviewing European initiatives on eliminating tax havens and offshore financial transactions, as well as the impact of these constructions on the EU´s own resources and budget.
