Mr. Eamonn Stapleton:

I will come in here. My contractors have done nearly everything we can do. We have electric vehicles and hybrid excavators in our range and we have solar panels on our sites. We are bringing in the batteries and the generators and so on. A good example is that we brought in electric bikes on one of our sites. Unfortunately, we had to charge them from a diesel generator because we could not get a power supply. All the things we are doing - today we are fitting closers on doors so the doors close when the guys leave the site office to avoid wasting heat - have achieved something for us that will be measurable in some way, but it is the tip of the iceberg. We do not like repeating ourselves, and I was aware that the transport people came in and spoke about HVO. I am aware of the background of HVO, which is a bit controversial in some respects as regards the provenance of it and so forth, but in my view, perfection is the enemy of the good. It is probably the best thing out there at the moment to make some progress on climate. It might not be the perfect solution. The perfect solution is probably through sustainable power generation for everything, but until we get there, we have to take those other opportunities. Our own company brought in HVO, but within a week or two the quantity surveyors were saying it was costing us too much money. When private enterprises, such as some of the pharmaceutical companies, are procuring work, they will ask what the extra cost is for using HVO and they will then make a decision themselves. Unfortunately, for public procurement that is not there yet. We are aware the Office of Government Procurement, OGP, are looking at various ways to incentivise contractors to be more sustainable when the procure a job, but it is just not there yet. It is taking time.
