How to have your beef and eat it too: reducing enteric methane emissions
At Zero Carbon, we have spent the past year thinking about one of the biggest sources of global greenhouse gas emissions: enteric methane emissions from livestock. These emissions remain unsolved as behaviour change and policy incentives have not taken off. In this article we review the scale of these emissions, the biochemistry in ruminant animals that produce them, the innovations being developed to solve them, and the drivers and barriers for these innovations. We share a
