We were founded with the purpose of helping the business community in the fight against climate change, reducing CO2 emissions, introducing the Low Carbon Strategy (Low Carbon Strategy), the Adaptation Strategy and the European Green Plan into their business plans and processes, and thus their sustainable - green economic development and growth in the Republic of Croatia and the EU. In the last 4 years, after we were selected in 2019 as the holders of the first international education in the field of ESG by IASE and "Exponential Education", we have been providing assistance to the business and financial community in the intensive integration of ESG into their operations, with the aim of improving business while preserving the environment and climate. Earlier years of work saw the Institute establish easier and faster communication between stakeholders and public administration, as well as complete legislation in the field of climate change, so that IICA now serves as the HUB of complete legislation and the most important climate policies in the Republic of Croatia. In cooperation with experts from the Ministry of Environmental Protection, several workshops were held, and members of IICA are long-term members of the official delegation of the Republic of Croatia at the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP) starting with the Paris Agreement in 2015, as well as several working groups at to the Ministry. In the meantime, IICA, including its membership (including large and medium-sized companies and banks), changed the composition of the institution, ensuring greater efficiency in the implementation of the Climate Change Adaptation Strategy, the Law on Climate Change and Protection of the Ozone Layer of the Republic of Croatia, as well as the European Green Plan, whose intensive integration into the EU economy will take place in the coming years, and in this way, we have enabled a faster transition of the Croatian economy to a low-carbon sustainable economy.
