Over the same period, the EU's gross domestic product (GDP) remained stable and saw only a very small variation (+0.05 % in the second quarter of 2023 compared to the same quarter of 2022). This information comes from data on quarterly estimates of greenhouse gas emissions by economic activity published today by Eurostat. Quarterly estimates of greenhouse gas emissions complement quarterly socio-economic data such as GDP or employment.
