How Values Shape Environmental Views

Values sit underneath every perspective, which raises an awkward question for a science course: how do you measure something as slippery as what people care about? The answer is the value survey, and the graph you get when you run one repeatedly.

📘 What you need to know

What values are

Values are the qualities or principles that a person believes have worth and importance in life. They guide behaviour, attitudes and decisions. Honesty, integrity, fairness and compassion are all examples.

Definition Values — qualities or principles a person believes have worth and importance, which guide their behaviours, attitudes and decisions.

Values affect people’s priorities, judgements, perspectives and choices. They feel deeply personal, but a range of cultural and social factors shape them. In some cultures respect for elders is highly valued, and that shapes how people interact throughout society.

From what you believe to what you do Surveys measure one end of this chain; behaviour graphs measure the other VALUES what you think matters ATTITUDES how you feel about it DECISIONS what you choose ACTIONS what you actually do a value survey measures here a behaviour graph measures here People do not always act on the values they report The gap between the two ends of this chain is itself worth investigating
Someone may say they value sustainability highly and still take the cheaper, dirtier option. That gap is a real finding, not a flaw in the survey.

Values in communities and organisations

Named examples. Greta Thunberg’s Fridays for Future movement calls for immediate action on climate change, reflecting values of sustainability and conservation. Patagonia demonstrates environmental stewardship by donating a share of profits to environmental causes.

When values clash

Different values regularly create tensions between individuals and between organisations. Conflict arises when strongly held values collide — for instance when some people want to express themselves freely while others want cultural sensitivity respected. In multicultural societies, working through those tensions takes understanding and respect for the diversity of values involved.

Value surveys

A value survey investigates the perspectives of social groups towards environmental issues. It helps you understand how environmental concerns are viewed and prioritised by individuals or communities — attitudes to renewable energy, to waste reduction, to conservation, or to using public transport instead of driving.

What makes a survey well designed

A well-designed environmental value survey should:

Its results should give insight into the attitudes, beliefs and values that influence how people view and respond to local and global environmental challenges.

Closed and open questions

Closed-ended questionsOpen-ended questions
What they areRespondents pick from a fixed set of options: multiple choice, rating scales, Likert scalesRespondents answer in their own words
StrengthResponses can be given a value or score, so they suit quantitative analysis and statisticsCapture more detailed responses and deeper insight into individual viewpoints
LimitationCan miss reasoning that falls outside the options offeredMuch harder to analyse and compare

Typical closed-ended questions in an environmental survey look like this:

Because these answers can be scored, you can run statistics on them and identify trends, correlations and patterns. If a town runs an education campaign to increase recycling, a survey gives you attitude data that can then be correlated with actual recycling rates to test whether the campaign worked.

How surveys are carried out

Surveys, questionnaires or interviews can all be used. Online survey tools are particularly useful because they let you collect data from a wider audience, in greater volume, in less time, and analyse it efficiently.

When an exam asks you to evaluate a value survey, the strongest point is usually about sampling. You cannot assume everyone in a social group has had the same experiences or faces the same challenges, so their views may differ sharply even within one community. A survey that misses that diversity gives you a confident but misleading answer.

Behaviour-time graphs

If a value survey is repeated over time, the results can be plotted as a behaviour-time graph. These show changes in behaviours or lifestyles over time, letting you visualise trends, patterns and shifts in environmental behaviour.

Reading a behaviour-time graph Household recycling rate in one town, 2013 to 2025 0 20 40 60 80 households recycling (%) recycling campaign launched before: about +2.6 points a year after: about +5.6 points a year 2013 2016 2019 2022 2025 Describe the trend, quote a figure, then explain the turning point The flattening after 2022 matters too: the easy gains have been made
Three features are worth naming here: the slow early rise, the change of gradient in 2018, and the plateau near 70%.

Behaviour-time graphs can track daily habits over a set period, such as energy consumption, waste generation or transport choices — a graph might show household electricity use falling over several months after LED lights are fitted or a thermostat is adjusted. They also track wider environmental behaviours such as recycling rates, composting and water conservation.

They are valuable for monitoring progress towards sustainability goals and evaluating the effectiveness of environmental initiatives, because they let you see the impact of an intervention and identify where more work is needed.

Worked examples

WE 1

Values and behaviour

Outline what is meant by values, and explain how they influence environmental behaviour. (4 marks)

Step 1: the definition Values are qualities or principles a person believes have worth and importance in life, such as fairness or compassion. Step 2: what they do They guide behaviours, attitudes and decisions, and they shape a person’s priorities and judgements. Step 3: the environmental link Someone who values sustainability may choose to cycle rather than drive, or pay more for a product with lower environmental impact. Step 4: beyond the individual Communities and organisations hold values too. Patagonia’s environmental stewardship shows in donating a share of profits to environmental causes. Values set priorities, and priorities drive the choices people actually make a named example lifts this from generic to secure

Designing a value survey

Suggest why closed-ended questions are often used in environmental value surveys. (3 marks)

Point 1: what they are Closed-ended questions give respondents a fixed set of options, such as multiple choice, rating scales or Likert scales. Point 2: the analytical advantage Responses can be quantified, given a value or score, so statistical analysis can be applied to the data. Point 3: what that allows This lets researchers identify trends, correlations and patterns — for example correlating attitudes to recycling with actual recycling rates to test whether a campaign worked. They turn opinions into numbers, and numbers can be analysed mention the trade-off: open questions give depth but are harder to analyse
WE 3

Interpreting a behaviour-time graph

Using the recycling graph, describe the trend and suggest a reason for the change after 2018. (4 marks)

Step 1: overall trend The recycling rate rises throughout, from about 18% in 2013 to about 70% by 2025. Step 2: the change of gradient The rise is slow until 2018, at roughly 2.6 percentage points a year, then becomes much steeper at roughly 5.6 points a year. Step 3: the reason A recycling campaign was launched in 2018, which is likely to have shifted attitudes and made recycling easier or more socially expected. Step 4: the later plateau After about 2022 the line flattens, suggesting the households willing to change already have, and further gains are harder to achieve. A steady rise, a sharp acceleration in 2018, then a plateau near 70% always quote figures with units, and name the turning point year

⚠ Common mistakes

Up next: Worldviews and the Environment. Values belong to individuals; worldviews are the bigger, deeper frames that whole groups share — and they are what environmental value systems are built from.
