Environmental Factors in PESTEL Analysis and Their Impact on Business

Updated 11 October 2026 · Fact-checked

Environmental factors are the 'E' in PESTEL. They cover the natural environment: climate change, resource scarcity, pollution and waste. They affect an organisation's costs, demand, regulation, reputation and risk. To answer a question, identify the factor, state its effect on the business, then say whether it is an opportunity or a threat and how to respond.

Understand Environmental Factors and Their Impact on Business

Environmental factors are the influences from the natural environment that affect how an organisation operates and what it can achieve. They are the E in PESTEL (Political, Economic, Social, Technological, Environmental, Legal). PESTEL looks at the external environment, which the organisation does not control but must respond to.

The main groups you need to know are:
- Climate change: rising temperatures, extreme weather, flooding, drought and rising sea levels.
- Resource scarcity: limited supply of water, energy, minerals, land and raw materials, which can push up prices.
- Pollution and waste: emissions to air, water and land, and the waste a business creates, such as packaging and by-products.
- Biodiversity and land use: damage to ecosystems and supply chains that depend on them.

These factors affect businesses in several ways. Costs can rise because of scarce inputs, carbon taxes or waste disposal charges. Demand can change because customers prefer greener products. Supply chains can be disrupted by floods or drought. Governments may bring in laws, so environmental factors often overlap with legal and political factors. Reputation can suffer if the business is seen as a polluter.

Environmental change is not only a threat. It can create opportunities: new products such as electric vehicles or recycled packaging, cost savings from energy efficiency, and a stronger brand. Investors and lenders also look at environmental risk, so it can affect access to finance.

In the exam, the same factor can hit different organisations differently. Climate change is a big risk for a farm or a coastal hotel. It is a smaller direct risk for a software firm, though its energy use and travel still matter. Always link the factor to the organisation in the question.

How to solve Environmental Factors and Their Impact on Business questions

Use this method for any question on environmental factors, whether it is a short objective test question or a scenario in Section B.

1Read the question and find the type of organisation: what it makes, where it operates and what it depends on.
2Classify the factor: climate change, resource scarcity, pollution and waste, or another environmental issue. Check it is environmental and not legal or social.
3Work out the direct effect on the business: costs, demand, supply chain, operations or reputation.
4Decide if it is an opportunity or a threat for this organisation. Some factors are both.
5Link to related factors if the question hints at them, such as a new law (legal) or changing customer attitudes (social).
6Choose the response: reduce impact, adapt operations, change products, report publicly or engage stakeholders.
7For multiple choice, match your answer to the exact wording and remove options that describe a different PESTEL factor.

Quickest way: Classify, Effect, Response

When to use it: Use this for one- and two-mark objective test questions when you have under two minutes per question.

Classify: ask whether the issue comes from nature or from the use of natural resources. If yes, it is environmental.
Effect: name one clear impact, such as higher costs, lost demand or supply disruption.
Response: pick the option that fits the organisation, such as recycling, energy efficiency or green products.
Check the other options: a law is legal, a change in attitudes is social, new machinery is technological.

Common mistakes in Environmental Factors and Their Impact on Business

Classifying a new environmental law as an environmental factor only.
The topic is environmental, so students stop there.
Fix: Look at the source of the pressure. A law or regulation is a legal factor, even when its subject is the environment. Mention the link, but classify by source.
Treating environmental factors only as threats.
News stories about climate change focus on harm.
Fix: Always consider opportunities too, such as new green products, energy savings and an improved brand.
Giving generic answers that ignore the organisation in the scenario.
Students memorise lists and write them out.
Fix: Tie each point to the business. Say how flooding affects this firm's warehouses, not just that flooding is bad.
Confusing environmental factors with social ones, such as customer preference for green products.
Both relate to attitudes and values.
Fix: The natural environment itself is environmental. Changing public attitudes or customer tastes are social. A good answer can mention both and keep them separate.
Mixing up pollution with resource scarcity.
Both relate to resource use.
Fix: Pollution and waste are outputs that harm the environment. Scarcity is about limited inputs. Ask whether the problem is what goes out or what runs short.
Listing factors without explaining their impact.
Students think naming the factor earns the mark.
Fix: Use the pattern: factor, effect, consequence for the business. Naming alone rarely earns full credit.

Worked examples

Example 1

A clothing manufacturer buys large amounts of cotton, which needs a lot of water. Several of its supplier regions have had repeated droughts. Which PESTEL factor is this and what is the likely impact? Answer in a short paragraph.

Show the solution

Classify: drought and water shortage come from the natural environment, so this is an environmental factor linked to climate change and resource scarcity.
Effect on supply: drought reduces cotton harvests, so supply falls.
Effect on cost: lower supply tends to raise cotton prices, which increases the manufacturer's input costs.
Consequence: the firm must either accept lower margins or raise prices, and may suffer supply disruption.
Response: find alternative suppliers in other regions, use recycled or other fibres, and reduce its own water use.

Answer: This is an environmental factor (climate change and resource scarcity). It is a threat because it reduces cotton supply and raises costs and supply risk. The firm can respond by diversifying suppliers, using alternative materials and cutting water use.

Example 2

Which ONE of the following is an environmental factor in PESTEL analysis? A) A rise in the interest rate. B) A growing public preference for products with less packaging. C) A shortage of fresh water in a region where a brewery operates. D) The introduction of a new data protection law.

Show the solution

Option A: interest rates are an economic factor.
Option B: public preference is a change in attitudes, so it is a social factor, even though it relates to packaging.
Option C: fresh water shortage is a limited natural resource, so it is environmental.
Option D: a new law is a legal factor.
Only option C comes from the natural environment.

Answer: C

Exam tips

Always classify by the source of the pressure: nature is environmental, laws are legal, attitudes are social.
In scenario questions, name the organisation's own activities when explaining the impact. Generic answers score poorly.
Remember opportunities as well as threats. A balanced answer shows stronger understanding.
In multiple response questions, read how many answers to select and check each option against a different PESTEL factor.
Link environmental factors to costs, demand, supply chain and reputation. These four effects cover most questions.

Environmental Factors and Their Impact on Business: frequently asked questions

What are the environmental factors in PESTEL analysis?

They are influences from the natural environment, such as climate change, resource scarcity, pollution and waste. They affect costs, demand, supply chains and reputation. Organisations cannot control them but must respond.

How does climate change affect business strategy?

It can raise costs, disrupt supply chains and change customer demand. It can also create opportunities such as green products and energy savings. Businesses may respond by cutting emissions, adapting operations and changing their product range.

Is an environmental law an environmental or a legal factor?

Classify it by its source. A law is a legal factor, even when it deals with the environment. In a written answer you can mention that the two factors are linked.

Can environmental factors be an opportunity?

Yes. Demand for low-carbon, recyclable or energy-efficient products can open new markets. Efficient use of energy and materials can also cut costs and improve the brand.
