Cut emissions with LPG & LNG

Cut harmful emissions

And meet Clean Air Zone requirements with Calor

Today’s vehicles are cleaner than ever, but they still contribute to air pollution – the greatest environmental risk to human health in the UK. Converting vehicles to run on much cleaner LNG and LPG Autogas can result in huge reductions in harmful emissions. That’s why these fuels are recognised by Defra’s Clean Air Strategy as a ‘here and now’ solution for displacing diesel-powered vehicles that are unlikely to be electrified – taxis, light vans and Heavy Goods Vehicles (HGVs).

Why tackling emissions from transport is crucial

  • Transport is currently responsible for 34% of all UK domestic greenhouse gas emissions1
  • Studies prove that long-term exposure to ultrafine particulates of 2.5 µm or less can decrease lung function and increase the risk of strokes and heart attacks2
  • Air pollution contributes to 40,000 early deaths a year in the UK (9,500 in London alone)3

Why BioLPG?

The EU’s Renewable Energy Directive is driving a need for businesses to switch to sustainable energy sources to meet a target of 20% of overall consumption by 2020. BioLPG, produced from wastes, residues and renewable vegetable oils, can be used in exactly the same way as conventional LPG and meets all the criteria set out in the Directive. Available in the UK only from Calor, BioLPG is:

  • Even greener – cuts CO2 emissions by 38% compared to oil4
  • Same great performance – no impact on acceleration or performance
  • No extra cost– doing the right thing doesn’t cost any more than conventional LPG
  • LPG-compatible – no changes needed to existing LPG equipment or infrastructure
  • The ideal backup for renewables – For most businesses a 100% renewable solution is not viable, so a reliable backup fuel is needed. For companies that are already investing to reduce their carbon emissions, it’s only logical to choose LPG, the lowest carbon fossil fuel, as a readily available alternative

Why LNG?

  • Greener - The cleanest burning fossil fuel available to the transport sector, LNG cuts particulate matter and reduces HGV CO2 emissions by between 10% and 20%, dependent upon duty cycle and vehicle type (according to industry experts)
  • Quieter - LNG reduces engine noise levels, allowing vehicles to operate in noise-restricted areas for longer periods
  • Cost-effective – In 2017, LNG pricing was on average 30% cheaper than diesel
  • Practical – Fast-growing network of 30 LNG refuelling stations strategically located around the UK and a pan-European network
  • Safer – LNG is non-toxic, non-corrosive and cannot spontaneously combust
  • Quick and easy refuelling – Filling up takes an average of four minutes5
  • Mainstream – Choice of LNG-powered vehicles already available from manufacturers including Iveco, Scania and Volvo

Why LPG?

  • In real-world testing, LPG has been proven to reduce NOx by 80% and PM by 99.9%.
  • On a well-to-wheel basis, LPG Autogas emits up to 21% less COthan petrol and up to 23% less CO2 than diesel.6

Legislation at a glance

Policies such as the Renewable Energy Directive and legislation like the Paris Agreement are increasing the pressure on companies throughout the supply chain to reduce their environmental impact. Air quality has become a hugely topical issue and with HGVs responsible for more than a quarter of roadside NOx emissions, governments across Europe are urging businesses to switch to more environmentally-friendly gas-based fuels.7 This is seen as one of the best options available to rapidly improve air quality on the UK’s roads.

With their high emissions of fine particulate matter that can have acute respiratory effects and cause cancer, diesel-fuelled vehicles are a particular target of clean air legislation.8 Indeed, London has announced the world’s first Ultra-Low Emission Zone requiring cars, vans and lorries to meet new, tighter exhaust emission standards. According to the Freight Transport Associationthe proposed HGV charges of typically £100 per day for all trucks other than the latest Euro VI models, could add 25% onto the daily running cost of a non-compliant vehicle. 

Switching fleets to dual fuel technology that allows the engine to burn a mixture of diesel and LPG – or, even better, 100% renewable BioLPG - is a convenient, cost-effective and simple solution for HGV managers who need to reduce their carbon output and transport costs to comply with increasing clean air legislation.
