In the United Kingdom professor Myles Allen of the university of Oxford states that currently methane emissions from livestock are wrongly blamed for causing global warming and that the current way the impact of methane on climate is measured, does not fit for that purpose. He states that carbon dioxide and methane have different effects on global temperatures but are incorrectly considered as equivalent. When correctly assessed it could be seen that agriculture is no longer contributing to an increase in global temperatures. That has been achieved largely by falling methane emissions from the ruminant sector. Climate policy has to be framed in terms of warming outcomes rather than emissions inputs, according to the professor.
