A report by the World Green Building Council finds that, in order to keep the global temperature rise below 2°C above pre-industrial levels, all new buildings must operate at net zero carbon by 2030 and all existing buildings must be renovated to operate at net zero carbon by 2050. Tunisia’s efforts to reduce the building sector’s carbon footprint culminated in the commencement of the Detailed Preparation Phase of the support project for the country’s Building NAMA titled, ‘Scaling-up Renewable Energy and Energy Efficiency in the Building Sector’.
