Question 20

Name and describe 2 approaches required by today’s society if OPL is to be achieved. (6)

Answer 20

Zero waste [1]
Reducing waste, reusing where possible, and ultimately sending zero waste to landfill [1].

Health and happiness [1]
Encouraging active, sociable, meaningful lives to promote good health and well-being [1].

• Sustainable Transport [1];
Reducing the need for travel, and encouraging low and zero carbon means of transport to reduce emissions. [1]

Question 21

Name and outline three of the principles of One Planet Living which your organisation could adopt. (6)

Answer 21

Zero carbon [1];
making buildings more energy efficient and delivering all required energy with renewable technologies. [1]

• Zero Waste [1];
Reducing waste, reusing resources where possible and sending zero waste to landfill. [1]

• Sustainable Transport [1];
Reducing the need for travel, and encouraging low and zero carbon means of transport to reduce emissions. [1]

Question 22

Explain why people living in a developed country will

have a larger ecological footprint than someone living in a developing country. (4)

Answer 22

An ecological footprint is based on consumption over a specific year [1];

It is expressed as the amount of land and sea (bio productive area) required to support the use of natural resources [1];

It is a means of comparing the usage of natural resources and lifestyles and checking these against nature’s ability to provide for this. [1]

This is likely to be greater for someone living in a developed country compared to someone living in a developing country because of their greater use of resources and production of waste. [1]

Question 23

Explain the linkage between a carbon footprint and an ecological
footprint.

Answer 23

A carbon footprint considers net greenhouse gases emitted [1];

and is an increasingly important part of the ecological footprint which considers a much wider range of environmental impacts in terms of resources used. [1]

Question 24

List two different strategies used by policy makers to reduce transport
demand.

Answer 24

Develop public transport networks. [1]

Promote walking. [1]

Question 25

Outline two of the principles of One Planet Living.

Answer 25

Zero carbon [1];
making buildings more energy efficient and delivering all required energy with renewable technologies [1]

Zero Waste [1]
Reducing waste, reusing resources where possible and sending zero waste to landfill [1]

Question 26

For each of the terms in I=PAT, outline two environmental impacts of the growing global need for resources.

Answer 26

Population
• More population means greater demand for natural resources [1];
• More demand for clothing, shelter, goods and energy to produce these [1];

Affluence
• Greater affluence = greater consumption and more waste generated [1];
• It is unsustainable to continue living a high consumption western lifestyle [1];

Technology
• Industrially-driven societies are energy intensive by nature [1];
• Less advanced technology used in developing countries is likely to cause more environmental impact [1];

Question 27

Explain how sustainable materials can help create a sustainable planet. (2)

Answer 27

Using sustainable materials, such as those with low embodied energy, sourced locally, and made from renewable or waste resources [2]

Question 28

Explain how Zero Waste can help create a sustainable planet.

Answer 28

Reducing waste, reusing/recycling where possible and ultimately sending zero waste to landfill [2]
