Austria's constitutional court on Thursday overturned a landmark ruling that had blocked Vienna airport's plans to build a third runway because of climate change worries.
In February, the Federal Administrative Court (FAC) had argued that the project would result in a "significant" rise in greenhouse gas output, contravening domestic and international undertakings to reduce pollution. The constitutional court said on Thursday that the FAC had committed several gross errors, including miscalculating the carbon dioxide emissions connected with the new runway.
A key travel hub between western and eastern Europe, Vienna airport handled 23 million passengers last year and has been wanting to construct the runway for a decade.
