Cycling to work is a fantastic choice of transport for our environment as it releases no carbon emissions or air pollution. Given that we live in a society today which is becoming more environmentally conscious, and as transport in general releases huge amounts of non-renewable resources, we’ve taken a look at the main benefits cycling to work has over driving or public transport.

CO2 + NO2 emissions from driving

Driving is one of the biggest contributors of CO2 emissions. According to Green Home, a litre of petrol creates around 2.3kg of CO2 emissions. If your commute to work was based on a distance of 10km every day, you would save 1.3 tonnes of CO2 emissions over the course of a year by cycling to work over driving.

As well as CO2 emissions, driving also massively contributes to air pollution which has detrimental effects to the environment as well as our health. Air pollution (NO2) is a universal problem, and it’s devastating that as many as 9,500 people die each year in London as a result of this according to a study commissioned by King’s College London for Transport for London and the Greater London Authority.

Breathing in the toxic fumes from Co2 + NO2 emissions reduces lung function by restricting the air passages which can lead to chest pain and asthma. In some respects, you could argue that it’s a catch 22 scenario, as if more drivers opted to cycle to work, they’re then actually more exposed to these emissions.

However, if more drivers who live within a rideable distance opted to commute by bike, they’d be playing a key role in reducing the sheer volume of these emissions.
