Is the European Union’s new CO2 strategy realistic?

In late November 2019, the European Commission decided that CO 2 emissions in the European Union would have to be reduced by at least 50% by 2030. We examine the feasibility of this target, looking at what it will entail : As a trend break; For fossil fuel consumption; For the investment drive in renewable energies; For the European Union’s energy intensity and growth. To reduce the EU’s CO 2 emissions by 50% in 11 years (by 2030; the current trajectory would lead to a 15% reduction), according to our calculations: Coal would have to be completely replaced by natural gas; Energy efficiency would have to improve by 17%; Fossil fuel consumption would have to be reduced by 29%; Renewable energy production would have to increase by 2.4 times, requiring a 2.6-fold increase in investments in these energy sources.
