Chapter 19: Problem 13

What are the major steps being taken to reduce emissions from passenger vehicles? What are the CAFE standards, and how are they changing?

Short Answer

Expert verified
Major steps being taken to reduce emissions from passenger vehicles include improving vehicle fuel economy, increasing use of alternative fuel vehicles, implementing policies like the CAFE standards, and encouraging behavioural changes. CAFE (Corporate Average Fuel Economy) standards, designed to improve the average fuel economy of vehicles, have continuously evolved to incorporate higher average fuel economy requirements.

Step by step solution

01

Definition of Passenger Vehicle Emission Reduction Steps

There are several major steps being taken to reduce emissions from passenger vehicles. These include: 1. Improving vehicle fuel economy through technological innovations; 2. Increasing use of alternative fuel vehicles; 3. Implementation of policies like the CAFE standards that advocate for fuel efficiency; 4. Encouraging behavioural changes, such as carpooling and public transportation use.
02

Understanding CAFE Standards

CAFE (Corporate Average Fuel Economy) standards are regulations in the United States, implemented by the National Highway Traffic Safety Administration, designed to improve the average fuel economy of cars and light trucks sold in the US.
03

CAFE Standards Changes

CAFE standards have been revised over the years to increase the average fuel economy requirements. The standards today are much more stringent compared to when they were first implemented, and they take into account both the size of the vehicle and the type of vehicle (car or light truck). Future changes aim further increasing fuel economy standards.
