Lowering beef cattle's finishing age key to Ireland fulfilling GHG reduction targets, Teagasc official states

 

 

Reducing the finishing age for beef cattle "is an essential element for Irish agriculture to meet its greenhouse gas (GHG) emission reduction targets," according to the Beef Enterprise leader in Teagasc.

 

Dr. Paul Crosson said the key to achieving this revolves around increasing the live weight gain of beef cattle, which in turn he said also improves farm profitability.

 

According to Teagasc between 2010 and 2022, the average finishing age of prime beef cattle reduced from 27.9 to 25.6 months, but this trend stalled in 2023 and 2024. It blamed challenging weather conditions combined with a reduction in the number of young bulls being produced which then increased the average finishing age to 26.5 months in 2024. 

 

But, reducing the finishing age for beef cattle is just one element that can contribute to lowering overall GHG emissions from agriculture.

 

The message from the Teagasc Climate Centre, which is headed up by Dr. Karl Richards, is that farmers in general need to actively reduce both nitrous oxide emissions and methane emissions.

 

Overall agriculture emissions decreased by 1.7% in 2024 according to a report published by the Environmental Protection Agency (EPA) on July 4.

 

In Ireland's Provisional Greenhouse Gas Emissions report for 2024 the latest figures suggest there was a reduction in national emissions of 2% compared to 2023, with reductions in almost all sectors – except for heating of homes and buildings.

 

Agriculture emissions decreased by 1.7% or 0.3 MT CO2e in 2024 compared with 2023 which the EPA said was primarily due to a 2.9% reduction in cattle numbers.

 

According to scientists at Teagasc, the three primary GHG emissions of concern for the agricultural sector are methane, nitrous oxide, and carbon dioxide. They have highlighted that methane emissions have decreased by 2.9% since 2023, while nitrous oxide and carbon dioxide have increased by 1.2% and 2.8%, respectively.

 

Statistics show that agriculture contributed 38% of Ireland's GHG emissions in 2024. But compared to the 2018 baseline for the 2030 Climate Action Plan target, agriculture emissions have decreased by almost 1.0 MtCO2e (4.6%).
