Negative global warming impact

Question

I am doing an LCA for a datacenter and my main focus is the global warming impact category. For some reason I get a lot of negative carbon dioxide emissions from one process especially: "Process steam from Light fuel oil 90%, consumption mix, at power plant, heat plant, MJ, 90 % efficiency". I know that the construction and usage of a datacenter do not reduce the carbon dioxide equivalents but I still get that result. Any help? I am using the databases EF database, ELCD and NEEDS and the impact assessment method ReCiPe 2016 (H).

Answer 1

It is likely from some very upstream process, usually packaging, that consume the carbon without making co2 emissions, you can check the sankey chart for a better idea of where the impacts are coming from.
