Effect of carbon price on production system responses to selection when feed price in the breeding objective is 30% lower than shown in Table 1^a,b,c,d. (^aFor a single generation of selection with selection intensity i = 1, ^b1 = $0/ton CO₂-e; 2 = $20/ton CO₂-e; 3 = $40/ton CO₂-e; 4 = $60/ton CO₂-e; 5 = $80/ton CO₂-e, ^cthe blue colour bars include GHG association with residual feed; the green colour bars exclude GHG association with residual feed, ^d$ net return is assessed using feed prices of Table 1)
