My Lords, it is a pleasure to follow the noble Lord, Lord Foulkes, as he bangs the drum for Scotland’s place in the union. I declare my interest as a lifetime livestock producer. I support my noble friend Lord Caithness in his Amendment 73, which flags up one of the great challenges facing agricultural production. Noble Lords will know that when the Kyoto Protocol was signed in December 1997, there was an awareness that, as well as the industrial emissions on which the subsequent climate action was largely focused, emissions from land use would need to be incorporated.
At that point, knowledge about emissions from agricultural production had not got much beyond rarefied academic studies. The difference now is that, since the Paris Agreement of 2015, Governments are required to pursue agricultural emissions as a major policy consideration. These amendments focus on that aspect. From a practical farmer’s point of view, I see immense scientific research around the world into both emissions levels and ways to reduce them. This indicates that we have not yet arrived at a full understanding of how these complex systems work and interact. I particularly think of the Oxford Martin School studies on the lack of persistent methane emissions in the atmosphere.
One of the quainter remedies I have come across to alleviate cattle emissions is mixing biochar—a form of charcoal—into the regular feed. As we strive to improve our current understanding of emission levels, I put it to my noble friend the Minister that the one thing we must not do is import agricultural produce—I think particularly of beef—which has a higher carbon footprint than that which we have achieved here, no matter how cheap it appears to be. It is important that our government policy and research have this element firmly in their sights. This amendment would ensure that it was on the face of the Bill.
I have much sympathy with Amendment 144A, in the name of the noble Earl, Lord Devon; this is obviously dependent on what methods are found to reduce greenhouse gas production. On Amendment 272, we need more clarity regarding what is meant by
“agriculture and associated land use”.
A great deal of government policy on achieving net-zero emissions seems to be based on taking land out of agriculture. The idea that agriculture on its own could reduce emissions to 100% below 1990 levels appears a bit fanciful.
