(15)In order to support a decrease in the use of polluting energy sources and a proper transition to renewable ones, it is also appropriate that companies that derive more than a set percentage of their revenues from coal, oil or gas are excluded from the EU Paris-aligned Benchmarks. The changes in the share of those energy sources out of the global primary energy supply from 2020 to 2050, as expected in the IPCC scenario, should be taken into account to set out those specific exclusions. In particular, according to table 2.6 of the Special Report on Global Warming of 1,5 °C from the IPCC, between 2020 and 2050, the use of coal is expected to drop between 57 % and 99 % and the use of oil between 9 % and 93 %, while the use of gas is expected to go up by 85 % or to drop by 88 %. Gas can be used during the transition to a low carbon economy, in particular as a replacement for coal, which explains its wider expected range of evolution, although the expected median decrease of its use is 40 %. For the same reason, it is necessary to exclude companies that derive more than a set percentage of their revenues from electricity generation activities.
