While short term effects of air pollution may only be felt by those most vulnerable - such as the elderly, children, or those with respiratory or heart problems - the long term impacts of air pollution are something we should all be concerned about. Short term exposure is an aggravating factor of respiratory and cardiac problems, but the reality is that we aren’t just facing short term exposure. The levels of air pollution have been harmful for years, meaning that we have all been exposed to the dangers of these pollutants over our lifetimes, particularly those living in busier urban areas or close to major transport routes.

We know that by driving the uptake of electric vehicles (EVs), we can help to tackle this serious pollution problem, and help drive forwards healthier environments, for healthier lives. Air pollution is one of the biggest threats to public health, and as road transport is a serious contributor, it only makes sense to bring a change to this industry. In fact, a study conducted in 2006 found that by reducing particulate matter (one of the key air pollutants from tailpipe emissions) by 10 µg/m3, the lifespan in the UK would be extended by 5 times more than by eliminating casualties on our roads, or 3 times more than by eliminating passive smoking.[1]

µg/m3 = the concentration of an air pollutant, given in micrograms per cubic metre of air.

In November alone, close to 4,400 kWh was supplied by Electric Blue’s four rapid chargers in Cambridge, which by conservative estimates[2] equates to circa 15,400 miles - enough to drive from Cambridge to Cairo and back again, twice![3] This distance equates to a conservative estimate of 2,503 kg of CO2 equivalent emissions taken off Cambridge’s roads - in just one month.[4]

EV charging

According to Trees for Life and The Forestry Commission Woodland Carbon Code, 15 trees would need to be planted in order to offset the above estimated amount of carbon. Granted, we’re all for planting more trees, and bringing more green back to our urban landscapes. But, the reality is that city centres are full of vehicles, which are currently belching harmful toxins into the atmosphere. By converting to EVs, we can achieve the same impact as creating more woodlands. Let’s remove the source - tailpipe emissions, rather than just covering the problem with a plaster.

With these figures, we can begin to see the direct impact that EV technology can have on our immediate environment, and our health. Now, imagine if we grew that network of just four chargers, to say, 21? That is exactly what we are planning in Cambridge, and we want you to be a part of bringing this revolution to your community.

By investing in our Innovative Finance ISA, you will be helping to grow the Cambridge Charger Network and demonstrate your commitment to a cleaner, healthier future for your community. Visit ethex.org.uk/ElectricBlue, for more information on the Bond offer, and how to invest.

Whilst the four chargers in one month equates to 15 newly planted trees, we project that with the full charger network, up to 3,763 tonnes of carbon will be removed from Cambridge’s streets in five years - the equivalent of 376 acres of new forest. Together, we can drive cleanly and breathe freely.
