Skymeter Smart Metering can significantly reduce transport emissions by reducing congestion and metering emissions

A Growing Problem

Road transport is a major and growing source of emissions: roughly 20% of world GHG emissions come from road transport, or 50% of the GHG emissions in major cities. In the US, emissions have doubled since 1970, even as car fuel efficiency improved … since the amount of driving tripled.

The Solution

Using the principle ‘feeling a pinch in the wallet drives change’, Skymeter's smart metering of vehicles asks drivers to pay more to use congested infrastructure and less otherwise. This spreads peak travel times allowing our roads to carry more total vehicle-miles, making our existing infrastructure more efficient.

Several cities are already benefiting from pricing:

  • In Stockholm, congestion pricing reduced city emissions by 12%
  • Milan’s ‘Ecopass’ (started in 2008) has reduced particulate matter 18%.
  • France’s Ministry of Sustainable Development will charge ‘Eco-royalties’ on all trucks, using a system like Skymeter’s, in 2011.

In addition to reducing congestion, Skymeter's vehicle meter can be used to calculate vehicle emissions. Motorists can then be charged based on how much their vehicles pollute, encouraging them to adopt cleaner vehicles or modes.

What the Experts Say

“Transportation CO2 reduction can be viewed as a three-legged stool: vehicle fuel efficiency, carbon content of the fuel itself, and miles driven. ”Urban Land Institute

“A fourth important factor is traffic …Traffic congestion contributes [further] to GHG emissions because vehicles produce [‘several times’] higher emissions per mile when they are driven at low speeds in stop-and-go traffic.”  – AASHTO

Metering and charging for road use, especially peak road use cuts congestion and greenhouse gas emissions. It has been proven to work on a massive scale: “London 20% drop in CO2 emissions … Stockholm 10-14% drop in CO2 emissions … ” Environmental Defense Fund
