Climate Change

Greenhouse Gas emissions


Greenhouse gas (GHG) emissions are increasing and investment in fossil fuel infrastructure continue. If we do not stop the increase in temperature, combined and unstoppable events will further climate warming and make vast regions of Earth uninhabitable (Ref. 1). If the temperature rise goes beyond a couple of degrees, in the worst case scenarios, massive migrations, conflicts and calamities of all kinds will lead to a population decline and a collapse of civilization as we know it. Civilization collapse is the loss of society´s capacity to maintain essential governance functions, especially maintaining security, the rule of law, and the provision of basic necessities such as food and water (Ref. 2).

The way to avoid this, is clear. Decarbonize as soon as possible all areas of human activity. For an extensive and detailed description of climate change, GHG emissions and its consequences, the reader is referred to many excellent books and articles about this matters, like the ones cited in references 3 and 4.

Transportation is one of the main sources of GHG emisssions. According to Ref. 5, transportation accounts for 16,2 % of global CO2 equivalent emissions, with 1,9%, 1,7%, 0,4% and 11,9% coming from air, water, rail and road transport contributions respectively. Urban traffic and congestion contribute largely to road transport emissions (Ref. 6). Many thousand million vehicles around the globe spend waiting hours consuming fuel and emitting polluting gases and generating zero economic benefit (Ref. 7).

The proposal described here will reduce emissions generated during traffic congestions.
