Berlin in International Networks

Berlin participates in international cooperations and municipal alliances which have been formed since the 1990s to exchange views and information and develop common strategies on climate protection and sustainability.

Numerous projects in Berlin on utilising renewable energies and increasing energy efficiency receive funding from European economic and technology support programmes, such as from the EU's Competitiveness and Innovation Framework Programme (CIP) for instance. The international associations of cities and communities serve as forums for exchanging views and information on local climate protection and sustainability strategies, in addition to fulfilling further important tasks. 


Through their various resolutions, municipal alliances advance the negotiations by international partners at climate framework conventions. Long before the Kyoto Protocol was adopted, the European municipality members in the Climate Alliance committed themselves to complying with concrete and ambitious reduction targets, thus setting the yardstick for the European negotiating position in the international climate protection negotiations.

Likewise, thanks to their climate protection successes especially, the alliances have become national and international representative bodies for the municipalities in European and national legislative processes, as well as in international negotiations. In this role, they participate in improving the European and national framework conditions for local climate policies.

C40 Climate Leadership Group

In 2005, delegates from 18 large cities around the world met in London to discuss global warming and adapting to climate change. At the end of the conference the delegates signed a communiqué in which they declared their readiness to reduce together the emissions of gases harmful to the climate.

By now the C40 includes the 40 largest cities in the world, the "megacities". They have formed a group which regularly holds summits, supported by the Clinton Foundation, in order to exchange information and views on common strategies and solutions to protect the climate.


Covenant of Mayors

The intention with the Covenant of Mayors is to support local administrations in becoming the leading players when it comes to introducing a sustainable energy policy. By the beginning of 2010, more than 1,600 cities had joined the covenant, including over 20 European capitals, as well as several cities outsider the UE. A total of more than 140 million citizens have been mobilised by the initiative.

Since it was founded in 2008, this initiative has grown rapidly and developed into an influential energy policy instrument bringing together mayors from through the EU, as well as from non-EU countries. The covenant signers – the mayors – have formally committed themselves to exceeding the European targets by introducing special plans of action for sustainable energy on a local level.



Berlin is a member of the international local government association ICLEI – Local Governments for Sustainability, which is committed to promoting sustainability strategies.

The network initiates and coordinates various projects and campaigns in the fields of sustainable development and environmental protection. ICLEI provides consulting and support to its more than 1,000 members globally in implementing sustainable urban policies, as well as arranging workshops, seminars and conferences. In addition it publishes a newsletter. The network has its international headquarters in Bonn; the offices of the European ICLEI Regional Organisation are in Freiburg. In Germany, 23 cities are members of the ICLEI.


Climate Alliance

The Climate Alliance is a European network for the protection of the global climate. The member cities and municipalities have committed themselves to reducing greenhouse gas emissions on a local level. Their alliance partners are the indigenous peoples in the Amazon rainforests.

Since 1990, Berlin has been a member of the Climate Alliance of European Cities with Indigenous Rainforest Peoples. Thus, Berlin was one of the founding members of what is today Europe's largest network of municipalities with a shared commitment to protecting the indigenous peoples in the rainforests. Since its foundation, more than 1,600 cities, municipalities and districts in many European countries have joined the Climate Alliance. When it became a member of the Climate Alliance, Berlin voluntarily committed itself to the following targets:

  • Reduce its CO2 emissions by 10 percent every five years,
  • decrease its per head emissions by half by 2030 at the latest (1990 basis year),
  • conserve tropical rainforests by abstaining from the use of tropical timber, and,
  • support projects and initiatives by the indigenous peoples.

City Network „Metropolis“

With more than 100 affiliate cities “Metropolis” is the largest international network for large- and capital Cities.

The main objective is the bilateral learning process, with the aim of continuously improving the standard of living for the inhabitants of large cities. The Berlin based activities of the Metropolis-network are coordinated by the Senate Administration for Urban Development and the Environment.



World Mayors Council on Climate Change

The World Mayors Council on Climate Change (WMCCC) is an alliance of more than 50 mayors addressing issues of climate protection and global sustainability.

The World Mayors Council on Climate Change is an amalgamation of committed mayors and local government leaders advocating an effective global climate agreement and the recognition of cities as stakeholders in global climate protection. The council plays a central role in the international climate protection agreement for cities, the so-called Mexico City Pact, and in the Cities Climate Registry. The World Mayors Council, which was founded in 2005 in Montreal, Canada, has its offices in the ICLEI's World Secretariat in Bonn.
