How do you make a diplomatic reception with zero carbon dioxide emissions for twelve hundred people? This is exactly what the Italian Embassy in Israel did, with the assistance of KKL-JNF, for Italy’s National Day, which is being celebrated at EXPO 2015 in Milan. In response to the challenge, KKL-JNF made a commitment to plant 120 trees to counteract the carbon emissions caused by the event. KKL-JNF experts calculated the quantity of trees that would have to be planted correlating to the number of guests.
