The subject of this paper is the impact of climate change on the local economy, and the City of Zagreb is taken as an example. The capital of the Republic of Croatia is a financial, scientific and health center, it is a city of many service activities with a developed processing industry. In recent times, Zagreb has become an important tourist center, and tourism as one of the economic sectors occupies a large share in the overall CO2 emissions generated by human activity through transport and accommodation. But just as tourism has an impact on climate change, so climate change has an impact on tourism. As the economic center of the Republic of Croatia with a large population, Zagreb is also a city of intensive traffic with increased greenhouse gas emissions. Accelerated urbanization has caused a natural imbalance resulting from climate change. Climate change is particularly reflected in the energy, water and health systems. The aim of this paper is to point out the consequences of global warming and climate change in the City of Zagreb and the inevitability of reducing emissions of harmful gases into the atmosphere and the adoption of measures that would slow down the growth of average global temperature. The City of Zagreb makes its maximum contribution to reducing industrial gas emissions, although its impact on global climate change is negligible. A big role in everything is played by the money that must be allocated in order for the proposed measures to be effective and lead to the stabilization of climate change, ie to slow down all the negative effects that we consciously or unconsciously spread around us.
