Total greenhouse gas emissions (without LULUCF)

There were relatively low greenhouse gas (GHG) emissions at the time of Slovenia’s independence in 1991, after which the transition to a market economy began, leading to an increase in gross domestic product (GDP) and higher emissions. These increased until 2009, when the global economic crisis halted GDP growth, resulting in a decrease in emissions with minor fluctuations. In 2023, the total emissions amounted to 14.804 Mt of carbon dioxide equivalent (CO₂eq). The most significant reduction occurred in the energy sector due to lower levels of coal consumption. The building sector also saw a notable reduction in emissions, attributed to milder winters, better insulation and increased use of wood and heat pumps, as did the waste sector, .

Reducing GHG emissions remains a challenge for Slovenia. By implementing additional measures – such as increasing energy efficiency, investing in renewable energy sources, promoting rail transportation and zero-emission vehicles while establishing the necessary infrastructure, constructing nearly zero-energy and zero-emission buildings, and – in the sectors not covered by the EU emissions trading system, Slovenia is on track to meet its emission reduction target.
