Greenhouse gas emissions from heavy-duty vehicles currently represent around a quarter of road transport emissions in the Union and, if no additional measures are taken, are expected to increase by 10 % between 2010 and 2030 and by 17 % between 2010 and 2050.
Faoi láthair is ionann na hastaíochtaí gás ceaptha teasa ó fheithiclí tromshaothair, agus thart ar aon cheathrú de na hastaíochtaí ó iompar de bhóthar san Aontas agus, mura ndéanfar bearta breise, meastar go dtiocfaidh méadú 10 % air sin idir 2010 agus 2030 agus méadú 17 % idir 2010 agus 2050.
