The escalating increase in disaster losses from floods, droughts, and other climate-related disasters both in developed and developing countries has become. However, on a global scale annual material damage from large weather events has increased 8-fold between 1960s and 1990s, while the loss of life has been brought down considerably. As such, each country is trying to reduce damage loss in response to extreme weather events. 

The United Nations Framework Convention on Climate Change (UNFCCC) thinks that important goal of governments is to limit the magnitude of future climatic change by reducing greenhouse gas (GHG) emissions. Governments in developed and developing countries are already implementing policies designed to adapt to the effects of climate change. As an example of this, the current EU has set a goal of carbon neutrality by 2050 through a policy called the Green Deal, and by 2030 it will reduce greenhouse gas emissions by at least 55% compared to the 1990s  and then they made Green New Deal. Green New Deal is to create sustainable development policies centered on the environment and people. They came up with realistic policies to boost the economy and promote employment through investment in the environment, such as responding to climate change and energy transition. It is trying to respond to the climate crisis and environmental problems by shifting to a low-carbon economic structure.
