So, I do think it helps us. It was a really important development. I actually like the way in which we use our knowledge analytical services to produce it independently within the board. So, rather than us feel that we use the data to only present the things that we want to look at, I think just having that kind of level of independence, even within the organisation, helps. I think there were three examples of areas that I think have moved on as a result of it, or maybe three or four.
Firstly, we'd had quite a lot of feedback over the years through the staff survey, and one of the key measures is about employee interaction. In fact, we've been able to get much higher levels achieved on our employee engagement. I think, actually, the pandemic helped in this respect, because we had to revert to different ways of working. So, we have what we call 'let's talk live' mechanisms; it allows us to remotely have a contact with the organisation. I think the highest number of staff we had in an individual session listening to the previous Permanent Secretary or myself is about 2,500—that's about half of our staff able to join because we're using the remote technology. I hope that we'll maintain those high levels, because we're trying to talk very visibly and personally to our staff and to the organisation.
A second area that's been improved and I think comes through the performance framework is actually around technology and the way in which that, again, has been so important in our use over the last two years, but people actually recognising that we have been putting in place actions to underpin that, from smart working through to actually the pieces of kit that we have.
The third area, which we're tracking, is actually around our environmental outlook and our estate, and if you look back over the last three years on the performance framework, we can see that our carbon emissions have reduced by 15 per cent. I think what is more telling, if you actually take the data back 10 years, we've actually reduced by 75 per cent in our carbon emissions across our Welsh Government estates over that period of time, and I think that, again, fits with our outlook as an environmental-supporting organisation as well.
And then the final area, and I think we were able to, I hope, give a bit of confidence on this in our last session, but there's also been progress around equality, diversity and inclusion as well, and having that more detailed opportunity to talk about some of the progress and measures in our last workforce planning session hopefully conveyed to you some of the data that we're actually looking at in terms of the performance report.
I've revealed to you my background, Chair, which means I kind of love data and could talk about it all of the time; there are so many other things that I could mention. It means that we know that 91 per cent of our staff feel that they've got the skills that they need to discharge the role, it means that I know that about 12,000 contacts have been made around individual learning and development activities, which is three times higher than just three years ago, so there's lots of useful information about the things that we're trying to do.
