The Importance of a Robust Baseline and Time Frame

There's also an additional aspect related baseline which is we inject the best companies to set targets based on a representative base year. A lot of companies especially early movers helped targets that were for instance linked to baseline in 1990 right. That was the year that was used in the Kyoto protocol crash course and so we tried to use the most recent and most representative base year but I showed that the baseline can actually be used to assess targets work. The last two that you mentioned of the initial five areas were robust baselines and time frame, why don't we talk about those together since they're both about timing.
