The questions in this Study Guide are meant to aid in accessing and understanding the information and concepts presented in the Inventory. There are seven questions, some with various parts, that will lead you to different parts of the Inventory, and introduce you to a number of ways of thinking about climate change in Rhode Island. In the blue sidebar you'll find links to both areas in the Inventory and external websites that will be useful in answering the questions.

 

Question #1: Baby, You Can Drive My (fuel efficient) Car

What would be the impact, in terms of greenhouse gas emissions,  if 1% of all the cars in Rhode Island were switched over, or traded in, for a Toyota Prius? Or a Honda Insight? 

       (Assume that the cars that are switched over are scrapped for parts and then crushed and the metal recycled. MTCE is "metric ton carbon equivalent,", a unit that takes into consideration the different warming potential of each greenhouse gas: carbon dioxide, methane
and nitrous oxide. )

        Steps to follow:      

               * How many cars were on the roads in R.I. in 1998? How many are estimated to be on the road in 2000?

               * How many miles were traveled by vehicles in 1996?

               *How many miles to the gallon do the Prius and Insight get respectively? (Assume that an average vehicle on the road gets 18 miles to the gallon.)

               *Determine how many MTCE are produced per Vehicle Mile Traveled.

               * How much better fuel efficiency do the Prius and Insight get than a an average car on the road?

               *How does this all translate into greenhouse gas emissions, in MTCE?
