This week, beef specialist Ciarán Lenehan examines Suckler cows and jumbo jets - the great carbon debate" target="_blank">the carbon debate and the role of the suckler cow. His analysis compares the relative greenhouse gas emissions from the volume of beef consumed by the average EU citizen each year against other activities, such as air travel and motoring. Despite the level of attention that beef production receives in the debate, his figures show 262kg of CO2 equivalents produced annually from the volume of beef consumed by the average EU citizen. To put into context, a return flight from Dublin to New York City equates to 1,394kg of CO2 equivalents. In the case of a jeep travelling 20,000 km per annum, the level of CO2 equivalents is 4,280kg.
