Westminster City Council King Street Low Carbon Trial - Client Report

TRANSPORTATION

DELIVERIES The largest items were the paving slabs which came from the Marshalls’ depot in Sittingbourne. These were delivered on a low loader to the compound on Carlton House Terrace. The slabs were delivered to site by an FM Conway grab lorry, powered by HVO on a ‘just-in-time’ basis. This meant that the compound on site was kept to a minimum and there was more room to store the excavator securely. Speedy Hire have an electric delivery vehicle which was not available at the time of the trial, but they delivered their equipment in a HVO transit van. All FM Conway delivery vehicles were fuelled with HVO and these made the bulk of visits to site. For smaller items like PPE, we trialled the use of a cargo bike, which is completely sustainable and can carry up to 250kg. During peak hours, deliveries via cargo bike from the Mandela Way depot in Southwark were actually faster than by lorry. To keep the carbon footprint low, no diesel was allowed on site. All deliveries and visitors to site had to use the most sustainable method available to them. Suppliers were asked to deliver either with electric vehicles, or where this was not possible, replace diesel with HVO fuel.

HVO FUEL Hydrotreated Vegetable Oil (HVO) is a synthetic paraffin fuel that is a direct replacement for diesel as there is no need to modify the existing engines or infrastructure. It is claimed that it reduces greenhouse gases by up to 90% compared to diesel, but for this exercise we have used a more conservative estimate of 50% carbon savings. For now, there are no electric or hydrogen alternatives for larger vehicles, so this is the most carbon efficient way to fuel deliveries. However, this is only an interim solution, as it is hoped that vehicle manufacturers will have electric vehicle options in place well before Westminster’s 2030 deadline for carbon neutrality.
