CSCS Test Question 2026 - Environmental Awareness & Waste Control

This CSCS Environment Awareness and Waste Control practice test contains 30 multiple-choice questions based on the topics covered in the CSCS Health, Safety and Environment Test. It is designed to help you improve your understanding of environmental responsibilities on construction sites and prepare for the real exam.

The questions cover key areas such as waste management, recycling, hazardous waste, pollution prevention, spill response, energy conservation, dust and noise control, wildlife protection, and environmental legislation. You will also be tested on reducing site waste, protecting watercourses, and following environmentally responsible working practices.

Some questions have more than one correct answer. To get the mark, you must choose all the correct options. There is no time limit, so you can take your time and focus on understanding why each answer is correct. The pass mark is 27 out of 30.
