Think green, stay healthy
Being kind to the environment could also benefit your health.
Flying is known to have its carbon footprint.
According to the International Air Transport Association (IATA), aviation contributes about 2% of the world's global carbon emissions – passenger numbers are predicted to double by 2037.
An economy-class return flight from London to New York emits an estimated 0.67 tonnes of CO2 per passenger, according to the calculator from the UN's civil aviation body.
When travelling next time, consider if alternative transport methods exist for both your health and reduced CO2 emissions.
