Crad­le to gate – crad­le to gra­ve

Pro­duct Car­bon Foot­print

Klasmann-Deilmann has alrea­dy published its “Cor­po­ra­te Car­bon Foot­print” (CCF) three times, in which it reports the emis­si­ons gene­ra­ted by the Klasmann-Deilmann Group as a who­le. The com­pa­ny also reports the car­bon emis­si­ons of selec­ted indi­vi­du­al pro­duc­ts in its “Pro­duct Car­bon Foot­print” (PCF).

When repor­ting the figu­res for 2015, the PCF was cal­cu­la­ted wit­hin two dif­fe­rent “sys­tem bounda­ries” for the first time: taking into account all fac­tors which are rele­vant for cli­ma­te chan­ge, we now cal­cu­la­te the car­bon foot­print for the indi­vi­du­al gro­wing medi­um from crad­le to gate, i.e. from extrac­tion of the raw mate­ri­al to the fac­to­ry gate, and also from crad­le to gra­ve, i.e. from extrac­tion of the raw mate­ri­al until com­ple­te decom­po­si­ti­on of the sub­stra­te.

The dif­fe­ren­ces bet­ween the two models are as fol­lows:

Crad­le to gate

This model records all emis­si­ons which are gene­ra­ted

  • during the extrac­tion or pro­duc­tion of raw mate­ri­als and
  • during pro­ces­sing into the finis­hed gro­wing medi­um

and which are thus gene­ra­ted direc­t­ly at our com­pa­ny or wit­hin our own sys­tem bounda­ries.

In terms of sim­pli­fied weigh­t­ing as a per­cen­ta­ge, the car­bon con­tent that occurs during the­se two pha­ses is equi­va­lent to less than thir­ty per cent of the total car­bon foot­print throughout the substrate’s pro­duct life cycle.

Crad­le to gra­ve

In addi­ti­on to the two pha­ses sta­ted above, this model also takes into account the car­bon emis­si­ons gene­ra­ted during the pha­se in which the sub­stra­te is used and in the end-of-life pha­se. Accoun­ting for a rough total of just over seven­ty per­cent, the­se emis­si­ons are gene­ra­ting during

  • trans­port
  • fur­ther use by the hor­ti­cul­tu­ral com­pa­ny
  • sale by the who­le­sa­le and retail tra­de
  • use by the con­su­mer and
  • recy­cling or alter­na­tively
  • was­te dis­po­sal

of a sub­stra­te.

When bro­ken down accord­ing to the above pha­ses, a lar­ge part of the emis­si­ons in this model occur out­si­de our sys­tem bounda­ries. We belie­ve it is our respon­si­bi­li­ty to con­ti­nue the poli­cy we have alrea­dy initia­ted and increa­singly gear our sub­stra­te assort­ment to ensu­ring that fewer green­house gases occur at each point of the value and con­sump­ti­on chain. This is why we have made spe­ci­fic mea­su­res to achie­ve the­se goals an inte­gral part of our cor­po­ra­te stra­te­gy, such as rai­sing the sha­re of alter­na­ti­ve raw mate­ri­als in our sub­stra­te mixes to 15 per cent by volu­me of our total annu­al pro­duc­tion by 2020.
