This program explores the automotive industry's move towards greener cars and the need for cities to balance cycling, public transport and cars within their overall infrastructure. So let's take a look at the transportation industry. Find out how to build a city around public transportation & the importance of the bicycle. Is there such a thing as a Green car? Have you heard cars can run on veggie oil, we'll show you how and take a look at biodiesel fuel. Increased levels of Carbon Dioxide are being expelled into the air from our tail pipes. Designing more sustainable transportation systems and being more thoughtful of how we design our cities is key by integrating walkability, bikeability and public transit. Building a city based on reduced carbon dependency by finding ways of redesigning or retro fitting neighborhoods and designing cities less dependent on fossil fuels is the way of the future.
