The United Nations and the European Union are the main allies in the fight against climate change, the consequences of which are creating a problem for this generation. In order to mitigate these consequences, measures, programs and action plans have been designed. Through regular conferences on climate change, the UN, with the help of state leaders and scientists, reports on the current state of the Earth. The average temperature on Earth has already risen by 1°C, the Paris Agreement agreed that joint forces will fight with sustainable development measures so that the temperature increase does not rise by another 1°C. The European Union designed the European Green Plan to provide member states with a basis for further progress in the fight against climate change. In all these decisions, plans and decrees, the concept of sustainable development circulates as a model for the future development of the economy. The European Union systematically invites member states as well as the rest of the world to join the challenge of the Paris Agreement and the climate-neutral continent of Europe throughout the coming period. All member states are free to design their own measures to contribute to the common plan. How big the problem of climate change is is also shown by the fact that it is an increasingly important item in the strategies of states. Sustainable development measures are the main inputs in this fight, but it is up to us to implement these measures and achieve the goal.
