The above comment didn't say CO2 emissions, it said that coal use is "down enormously" with a "tiny bit of gas generation growth". The reality is that overall fossil fuel use remains largely the same, coal reductions were matched by natural gas increases.
Likewise, CO2 reductions aren't very large, and is still above average for EU member states: https://www.eea.europa.eu/data-and-maps/daviz/co2-emission-i...
