“The fact that so many countries are cooperating despite all the difficulties is already a success,” Swiss Ambassador for the Environment and Head of International Affairs Felix Wertli told Keystone-ATS news agency.

Ten years ago, the international community reached an agreement on climate change in Paris. In ten days' time, representatives of almost 200 states will meet again, this time in Belém (Brazil), to negotiate the implementation and evolution of this agreement.

Switzerland will work to ensure that all countries submit new ambitious reduction targets for greenhouse gas emissions, particularly those currently responsible for releasing large quantities of CO2 into the atmosphere, Wertli said.

The Paris Agreement commits almost all states in the world to take measures to limit global warming to well below two degrees Celsius, if possible, to 1.5 degrees compared to the pre-industrial era. To achieve this goal, countries must reinforce their national targets every five years.

These updated targets will be the focus of this year's negotiations.“This is about countries taking stock of what they have achieved so far under the Paris Agreement and identifying what efforts are needed to close the gap to the 1.5 degree Celsius target,” the ambassador explained.
