In general lignite burning coal-fired power stations with subcritical boilers (in which bubbles form in contrast to the newer supercritical steam generator) emit the most.
[5][6][7][2] In early 2021 the EU carbon price rose above 50 euros per tonne, causing many of the European plants listed below to become unprofitable,[8] and close down.
[9] However, because many countries outside Europe and the USA do not publish plant level emissions data it was difficult to make up to date lists.
Public information from space-based measurements of carbon dioxide by Climate Trace is expected to quantify CO2 from individual large plants before the 2021 United Nations Climate Change Conference,[10] thus enabling large polluters to be identified.
[11] In 2015 the Stranded Assets Programme at the University of Oxford’s Smith School of Enterprise and the Environment published Stranded Assets and Subcritical Coal report analyzing inter alia carbon intensity of subcritical coal-fired power stations of 100 largest companies having these power stations.
