Climate change is one of the biggest challenges facing the world today. Due to human activities, especially the increased emission of greenhouse gases, the atmospheric concentration of these gases has increased dramatically. One of the most important greenhouse gases is carbon dioxide (CO2), which plays a key role in global warming, and it is precisely CO2 that is the reason for drawing up the Green Plan by the EU, which aims to neutralize the climate by 2030 or 2050. CO2 is a gas that occurs naturally in the atmosphere, and the problem is that its concentration is increasing dramatically due to human activities, such as the burning of fossil fuels, industrial processes and deforestation. CO2 is important because it acts as a greenhouse gas that traps heat in the atmosphere, thus creating a greenhouse effect and warming the planet. Without the natural greenhouse effect, the Earth's temperature would be extremely cold, and there would be no conditions for life as we know it. Because it is used for warming, the change in the proportion of certain gases such as CO2 (although other gases also affect the increase of the greenhouse effect), additionally warms the atmosphere and can have a fatal effect on life on planet Earth. Rising temperatures lead to extreme weather conditions such as heat waves, droughts, floods and storms. Such extreme weather events can cause loss of life, damage to infrastructure, increase the risk of fire and adversely affect agriculture and water resources. Climate change also has a negative impact on ecosystems and biodiversity. Increasing temperatures, changes in precipitation and oceanic changes lead to changes in habitats and migrations of animal species, thus causing extinction of species, disruption of the food chain, and the like.The European Green Plan is a comprehensive strategy to combat climate change. Through various policies and measures, the EU aims to reduce greenhouse gas emissions, promote sustainable energy, encourage the transition to clean industry and renewable energy sources, and preserve and restore ecosystems. The goal is to create a sustainable, climate-neutral Europe that will reduce the negative consequences of climate change, protect nature and ensure a better future for all citizens. The analysis of the Green Plan of the European Union concludes that the plan is ambitious and comprehensive, but it is necessary to continuously monitor its implementation and adapt policies to new circumstances, especially with regard to changes in the global economy and climate conditions. The primary strength of the plan lies in the combination of long-term goals, such as climate neutrality by 2050, and integrated strategies in the fields of energy, industry, agriculture and biodiversity conservation. The Green Plan represents a necessary step towards a sustainable future, but at the same time it brings with it great challenges. It is extremely positive that it places climate neutrality and environmental protection at the center of economic and social changes, and that it encourages innovation, circular economy and energy efficiency, because it is precisely in these areas that the key to future competitiveness and the development of new jobs is. However, the high costs and the required political will seem like potential problems that the whole idea could run into. The fact that around 260 billion euros of additional investment will be needed annually sounds like a huge burden, especially in countries that are already struggling with economic difficulties.The European Green Plan is a comprehensive strategy to combat climate change.
