SPM in UN and other languages

Translation of the AR5 SYR SPM from English into the other five official languages of the United Nations is being done by translators working for the WMO Language, Conference and Publishing Services Department. The assistance of scientific translation editors for each language is gratefully acknowledged.

UN Languages

Other Languages

A number of countries are undertaking translations of the SPMs into languages that are not official languages of the United Nations. IPCC welcomes these initiatives but would note that the translations are prepared under the responsibility of the respective country or institutions. The IPCC does not assume any responsibility for the accuracy of these translations into non-UN languages. In working to achieve the widest possible dissemination of IPCC knowledge, the IPCC is pleased to assist in making these translations available.
