In the last years, in response to the expected increase in average daily temperatures as well as in the number of hot days and of heatwaves due to climate change, Paris Heatwave Plan is drawn up and measures to prevent heat stress (i.e. green gardens, parks and roofs and use of water for cooling) are implemented. Furthermore, floods are not expected to be more or less frequent due to climate change. So the purpose of the Adaptation Strategy, one of the operational documents of the Paris Climate & Energy Action Plan, is to prepare the city for both future climate changes as well as for future scarcity of certain resources such as water, energy, food and 1. This is translated into four main objectives: to protect Parisians from extreme climate events; to ensure the supply of water, food and energy; to live with climate change with a more sustainable city planning; to foster new lifestyles and boost solidarity. In this sense, Paris Climate Bond aim (issued in November 2015) is to raise finance for climate change mitigation or adaptation-related projects or programmes. It is a form of loan: the holder of the bond is the lender (creditor), the issuer of the bond is the borrower (debtor), in this case the City of Paris. Bonds provide the borrower with external funds to finance long term investments. Twenty per cent of the bond funds have been assigned to adaptation projects. Currently, 2 projects with a climate adaptation objective are being implemented. They involve planting 20,000 trees in the city and creating 30 hectares of new parks by 2020. The new trees will be planted in the inner city of Paris, in the streets and at public facilities (i.e. school playgrounds, gymnasiums, etc.). Since the beginning of 2016 until the summer of the same year, around 2,000 trees have already been planted. The new parks will be created both in the urban renewal zones of Paris as well as in some already existing neighbourhoods of Paris where local places can be transformed into little local parks for residents. In line with Adaptation Strategy, objective of both adaptation projects is to reduce the urban heat island effect and increase thermal comfort within the city.
