The Net-Zero Advisory Body takes a look at expert advice from economists. That advice for decades has been that one of the most efficient mechanisms is a carbon price. I think there's a question about efficiency related to whether it's a public-facing carbon price or it's an industrial carbon price.
The reality is that the carbon price on the oil and gas sector is incompletely administered. There are exemptions that apply to different companies in different regions. One of the key things we would like to see is a cleanup of the exemptions so that we get full benefit from the pricing of emissions from the oil and gas sector.
