1. An interior automotive part prepared from a thermoplastic composition comprising
from 48-95 wt. % based on the weight of the composition of at least one heterophasic propylene copolymer;
from 0-14 wt. %, based on the weight of the composition of an ethylene-α-olefin elastomer comprising ethylene and at least one C3 to C10 α-olefin;
optionally >5-15 wt. % based on the weight of the composition of high density polyethylene (HDPE);
from 1-30 wt. %, based on the weight of the composition of high aspect ratio (HAR) talc as a filler;
from greater than 0 to less than 0.01 wt. % based on the weight of the composition of another talc;
from 0.05-1 wt. % based on the weight of the composition of a phenolic antioxidant additive;

from 0-3 wt. % based on the weight of the composition of one or more additional additives;
wherein less than 0.01 wt. % of glass is present; and
wherein less than 0.01 wt. % of styrene-ethylene-butylene-styrene (SEBS) is present;
wherein a total carbon emission is at most 50 microgram of carbon/gram.
