(8)A decarbonisation based only on Scope 1 and Scope 2 GHG emissions could lead to counterintuitive results. It should therefore be clarified that the minimum standards for EU Climate Transition Benchmarks and EU Paris-aligned Benchmarks should not only consider direct emissions from companies, but also emissions assessed on a life-cycle basis and thus including Scope 3 GHG emissions. However, due to the insufficient quality of data currently available for Scope 3 GHG emissions, it is necessary to set out an appropriate phase-in timeline and to allow for the use of fossil fuel reserves for a limited period of time. That phase-in timeline should be based on the list of economic activities set out in Regulation (EC) No 1893/2006.
