Professor John Sweeney:

I refer to the key aspect of nitrogen. I would like to explore that further with members. We were going very nicely in 2010, when we were consuming 300,000 tonnes. We are now consuming 400,000 tonnes per year and that is driving our greenhouse gas emissions.

Finally, there is the aspect of firms. Firms are becoming more sustainable and more amenable to including their scope 3 emissions or supply chain emissions.

We should be fostering that a lot more because they will also have budgets that they have to meet. We can do a lot more in terms of procurement and encouraging them to count more of their downstream emissions, and this will possibly also help our hard-pressed agricultural community.
