W 2 degrees Celsius (and even 1.five) above pre-industrial levels [24] was the main consensus accomplished amongst the parties for the Paris Agreement, leading to a variety of environmental and financial consequences for the parties [25]. Nations had been obliged to elaborate national solutions (Nationally Determined Contributions) based on their national circumstances and capabilities as feedback to global policy aimed at developing climate resilience [26,27]. Following the main pillars in the Paris agreement and to lower the emission of the greenhouse gases (mostly carbon dioxide) accountable for international warming, the European Commission introduced the European Green Deal [12] constituting a European roadmap, which presents the directions and suggestions for European nations to grow to be climate-neutral by 2050. The European Green Deal assumes, inter alia, supplying clean, affordable and secure energy, mobilizing the business to get a clean and circular economy in addition to a zero-pollution ambition for any non-toxic environment. The scenarios of decarbonization and climate-resilient future presented by the European Green Deal seem to become feasible, as lots of analyses and forecasts confirm the boost of the share of renewable resources in energy production up to two-thirds inside the subsequent 30 years [28]. Although in some analyses it is predicted that the global demand for coal is set to remain significant in the coming years (mostly as a result of unrelenting demand for this fuel in China and India) [29], in long-term it really is estimated that as a consequence of low fees and coupled with power efficiency, the share of renewable energy sources (RES) will be more than 80 in 2050, using the domination of wind and solar power [29,30]. The pandemic of COVID shook the power market–in 2020 there was a decrease in energy demand by five , in CO2 emissions by 7 as well as a drop in investments by 18 [31]. Assuming that after the pandemic is brought beneath control in 2023, the demand for energy will increase to its pre-crisis level, the demand for renewable energy will continue to develop, and hence the consumption of coal in the power mix in 2040 will fall under 20 [31]. In Poland, the total energy consumption in 2019 amounted to 4405.eight PJ. The share of hard coal amounted to 37.0 , brown coal 9.1 , crude oil 26.three , organic gas 16.1 , renewable energy carriers 9.3 , and other carriers two.2 . Indigenous production of main power in Poland has been falling since 2015. The share of tough coal as a principal power carrier has been also declining, nevertheless it nevertheless remains the most critical supply of power. In 2019, its share was 56.2 . The second biggest carrier when it comes to production was lignite using a share of 15.2 . The share of all-natural gas in production was five.five , crude oil 1.five , and the share of other, largely renewable energy sources, 18.3 . In 2019 the largest share in direct energy consumption (34.6) was held by the industrial sector. Other sectors dominating in direct energy consumption were transport (28.1) and households (21.7) [32]. The substantial part of fossil fuels in Poland’s power mix translates into a high degree of CO2 emissions in comparison to the European Union. The Benfluorex hydrochloride latest information show that Poland is responsible forEnergies 2021, 14,three of11.two of CO2 emissions in the EU, which places it in third location following the largest emitters: Germany and Italy [33]. The infamous position amongst the emitters is just not surprising, as Poland’s Energy Policy until 2025, adopted in 2005, assumed that the resources of really hard coal and lignite.
