The Global Festival of Action for Sustainable Development, organized by the United Nations Campaign Office for Sustainable Development (UN SDG Action Campaign), is taking place for the fourth time in Bonn. The three-day conference is aimed at actors from all over the world who are committed to the implementation of the Sustainable Development Goals. The Global Festival of Action offers an interactive framework for the presentation and exchange of new approaches, methods and developments for the implementation of the SDGs. Target groups include representatives of national governments, municipalities, international organizations, the creative industries, the private sector and civil society. About 1,500 participants are expected to attend.

The City of Bonn will be represented at the conference with an information stand and the "SDG wheel of fortune".

The annual meeting of the Subsidiary Bodies to the United Nations Framework Convention on Climate Change is expected to attract some 3,000 delegates to Bonn again in 2020. The meeting serves to prepare the 26th Conference of the Parties to the Climate Change Convention, which is to be held in Glasgow, Scotland, in November 2020. The City of Bonn, together with the Federal Environment Ministry, is traditionally hosting a reception for the delegates to the Bonn preparatory conference. In addition, the City of Bonn supports the Climate Secretariat in public relations and logistical matters.

The Bonn Global Forum builds on the 10 years of experience gained at the ICLEI Resilient Cities Conference and repositions it in terms of content. The aim is to embed the topic of resilience more strongly in the overall context of climate protection and adaptation and to take account of current developments at the municipal level (including resolutions on climate emergency and climate neutrality). Furthermore, cooperative measures involving various levels of government are to be highlighted and the connections to related topics (e.g. climate financing) and sectors (e.g. science) are to be more strongly emphasized and linked more closely with the organizations based in Bonn (UN, science).
The conference is organized by the city network ICLEI with the support of the City of Bonn. Amongst other measures, the City of Bonn supports the conference through public relations activities, the offer of specialist excursions and networking events for conference participants.

In 2002, the World Summit on Sustainable Development agreed on the 2020 chemical target to minimize the negative effects of chemicals on environment and health by that date. To implement this 2020 goal, the Strategic Approach to International Chemicals Management (SAICM) was founded in 2006.
The Strategic Approach provides the framework for cooperation between all relevant stakeholders and sectors on overarching issues of international chemical safety. The decision-making body is the International Conference on Chemicals Management (ICCM). The mandate of the Strategic Approach ends in 2020 and an intersessional process is to develop recommendations for shaping the Strategic Approach and international chemicals and waste management after 2020.
Decisions will be taken by the 5th International Conference on Chemicals Management (ICCM5) from 5 to 9 October 2020 under German chairmanship in Bonn.
The United Nations is the organizer of this conference. The Federal Government (BMU) will support the conference in terms of content, protocol, technical and organizational matters. ICCM5 is expected to be attended by 1,500 representatives from all groups of actors and sectors relevant to SAICM and will discuss the future chemicals policy in plenary sessions and working groups. A ministerial segment in the form of a conference is also planned.
The City of Bonn supports the Federal Government by arranging room allotments for conference participants through Tourismus & Congress GmbH, as well as in the area of public relations work and by holding a reception as part of the ministerial segment.
