Fair Fuel APPG for UK Motorists and UK Hauliers August 2021 Page | 36 Current atmospheric CO 2 levels of 400ppm allegedly, are close to plant starvation levels and if anything, we should be boosting concentrations, not trying to get to net zero. CO 2 has been the focus of some very bad press and humanity has been blamed for releasing tonnes of the stuff into the atmosphere causing runaway global warming. However, a few hours of study of the real science shows beyond doubt that CO 2 is not the miscreant it is purported to be. That governments have bought into this fable is going to cost you and me a lot of money. And our freedom! Secondly, even if CO 2 is at the root of all claims of global warming our efforts to turn the off switch to ‘stop’ are limited. For an analysis of this aspect of the problem we must look to the US National Centre for Atmospheric Research who were jointly funded by the UN and the Federal Government to create a system to look at the impact that a net zero scheme would have on global temperatures. The MAGICC system, Model for the Assessment of Greenhouse Gas Induced Climate Change, looked at the immediate cessation of using all fossil fuels in the USA and concluded that “no matter what assumptions are used for the amount of or increase in fossil fuel generated CO2 in the US, from small amounts to very large ones, complete elimination of all fossil fuels in the US immediately would only restrict any increase in world temperature by less than one tenth of one degree Celsius by 2050, and by less than one fifth of one degree Celsius by 2100”. Even if one is a true believer in the climate change paradigm, the costs to families, society and the national well-being is an eye watering prospect. For those convinced that climate change is the greatest deception ever imposed on humanity the costs are a travesty.” What about particulate matter? Emissions’ Analytics recent newsletter articulated: While we have been occupied with reducing exhaust emissions to control air quality problems, other sources of pollutants have not received the same attention historically. Now that tailpipe emissions of modern internal combustion engines (ICEs) in both Europe and US are generally well below regulated limits for pollutants, focus is now turning to ‘non-exhaust emissions’, which cover tyres. Oh! EVs need tyres along with bicycles and e- scooters! In legal but extreme driving, enough to significantly reduce the lifespan of a vehicle’s tyres, that factor increases to around one thousand. In addition to tyres, non-exhaust emissions cover material from brake and road wear, as well as resuspended solids, whipped up from the carriageway by the moving vehicle. Of these, tyre wear emissions are probably the largest and fastest-growing component. Brake wear emissions are forecast to fall as regenerative braking becomes more widespread. Emissions Analytics’ testing shows that, in normal driving, tyre wear emissions are about one hundred times greater than tailpipe particle mass on a modern ICE vehicle.
