Biggest polluters account for over 20% of emissions 

The report indicates that the most polluting companies were responsible for 20.5% of the carbon market’s total emissions. At the same time, they were also among the companies that reduced these emissions to a greater extent, which in the case of Spain increased by 9% by 2022, according to Spanish newspaper El Economista. This mainly involves Cemex, which reduced its emissions by 16%; Arcelormittal, by -10% and FCC, by -2%.Cepsa and Iberdrola remained at similar levels.  

Drought affecting emissions 

Another conclusion from the study is that the drought had an impact on emissions, as it led to a 40% drop in hydroelectric production, while emissions from gas-fired power plants increased by 53% and from coal-fired plants by 56%.
