The economist David Rosnick estimated that if factories and offices operate fewer hours a day, the energy usage will drop, and carbon emissions will be reduced. If such strategy is implemented, then half of the expected rise in global temperatures could be prevented.
Rosnick also suggests that governments in developing countries should decide on the most suitable work schedule, choosing between more work, as in the U.S., or less output and less emissions, as in Europe.
It is important to note that another influencing factor is what people do in their free time. The personal and national economic climate of places are also very important. Reducing working hours in places with financial difficulties and crisis could have devastating effect on the national economic growth.
In order to prevent this, countries should direct more investments towards green technologies.
And even if working hours are not reduced, we could still implement some energy saving strategies- turning off printers and lights, investing in laptops instead of desktop computers and using energy saving bulbs, are just some of them
