Energy Efficiency.: Transportation

Year 8 Science

Climate Works

In 2018, Australia’s transport emissions were up 19% from 2005 levels, making the sector core to achieving net zero emissions by 2050. Australia lacks light vehicle emissions standards, one of only a handful of OECD countries without them. But the sector can take advantage of electric vehicles, mode shifting and low emissions fuels.


This paper discusses the individual benefits of each of the technologies required for Renewable Transport, then how their combination can lead to even greater reductions in fossil fuel consumption and greenhouse gas emissions. The payback period for the electric vehicle’s initial price premium is estimated from fuel savings and income generated by providing ancillary services to electric utilities.


What possible solutions are there to the problems of climate change and decreasing availability of fossil fuels?

In this Our Changing Climate environmental video essay, I look at the greenest form of travel. Specifically, I look at the carbon footprints and emissions of trains, cars, planes, and buses when traveling on vacation or for business. Ultimately, the greenest way to travel greatly depends on the context of the trip. For example, the number of passengers or distance travel greatly affects the efficiency and the "greenness" of the trip.

The transportation of people and goods is one of the greatest challenges facing cities today, as it is responsible for over a third of global carbon dioxide emissions. Fortunately cities around the globe are rising to this challenge, and are busy developing and implementing more sustainable modes of transport.

Imagine a city where the transportation system is efficient, supports a thriving economy and provides citizens with healthy and mobile options; a system that is powered by renewable energy. Watch this video to learn how Vancouver will become a city where our entire transportation network will run on renewable energy before 2050.

Your Home

Some of your most important decisions on the energy your household consumes relate to transport. Where will you live? Is there good public transport? Will you have to buy a second car? You may have an energy efficient home but still be a high energy household if you rely heavily on your car. Transport is a crucial ingredient in the good design of homes, neighbourhoods and cities.


The International Council on Clean Transportation is an independent nonprofit organization founded to provide first-rate, unbiased research and technical and scientific analysis to environmental regulators. Our mission is to improve the environmental performance and energy efficiency of road, marine, and air transportation, in order to benefit public health and mitigate climate change.

Climate Change Authority

The transport sector accounts for 16 per cent of Australia’s greenhouse gas emissions. Light vehicles account for the largest share—10 per cent of Australia’s total emissions.
