A quick and simple way of reducing CO2 emissions would be for more people to work from home. Countless people are commuting daily to perform work that does not need to be done in an office. Governments could provide a tax incentive or other benefits to employers for each person working from home. Small employers may no longer require an office, saving money and the CO2 emitted from heating and lighting. Company meetings could be conducted remotely or in premises hired for the duration of the meeting only. Wi-Fi ensures employees no longer need to be under the same roof!
Why is this important?
Reducing CO2 emissions must, logically, be every countries number one priority. All other policies are irrelevant if we don't have a planet!
