Ved beregning af GWP-værdien for ikke-fluorholdige drivhusgasser i præparater finder de værdier, der er offentliggjort i IPCC's første vurdering, anvendelse, jf. Climate Change, The IPCC Scientific Assessment, J.T.
For the calculation of the GWP of non-fluorinated greenhouse gases in preparations, the values published in the First IPCC Assessment shall apply, see: Climate Change, The IPCC Scientific Assessment, J.T.
