We do not provide normalised figures for our CO2 emissions nor ratios of CO2 to production, financial results or employee headcount, as we do not believe that reporting a normalised figure meaningfully contributes to an understanding of our performance. The scope and diversity of our products make a single production figure impossible to calculate and our financial results are impacted by commodity prices and foreign exchange rates, which are outside of our control. In addition, due to the nature of the exploration, development and the production cycle, our CO2 emissions do not necessarily correlate to our employee headcount.
