This isn't a very good take. Business leaders are generally fine with reasonable regulations that are evenly applied and easy to comply with. The operations out there spewing methane are essentially free riding, and their competitors who don't do that probably want better enforcement. Obviously this isn't universally applicable to all conceivable regulations, but its true enough in this case.
My point is that businesses aren't even necessarily against this kind of regulation. The reality is that controlling methane requires a lot of unsexy followthrough and monitoring, and international deal making. This is a political failure.
