The general tenor of a lot of agricultural objections to these kinds of scenarios tends to be along the lines of "everyone else must fully eliminate all of their emission scenarios before we are forced to reduce a single thing." You can see a similar effect in the US's Western megadrought crisis, where farmers are adamant that all possible water use reduction in urban and suburban areas are done before you start discussing reducing the water use that goes to agriculture. And I've also seen some similar stories about Chesapeake Bay nitrogen runoff--fix all urban uses before you ask farmers to make changes to their fields.
