The paper contains characteristics of selected environmental elements of EU countries in terms of ecological safety. The work included issues of primary energy, renewable energy and greenhouse gas emissions. Presented statistical data comes from the European Statistical Office. The time range covered the period from 2004 to 2013. People through their activity cause a number of changes that lead to hazards in the environment. One of them is climate change. Preventing these changes can be achieved by increasing the share of energy from renewable sources and reducing greenhouse gas emissions. It must be achieved through collective actions of all countries worldwide including the EU.
