Resource Use & Global Warming Revision Notes | GCSE AQA Business

1. Why Resource Use and Global Warming Matter to Business

Here is the central tension every business faces today: the resources that power production — oil, gas, metals, water — are running out, and the act of using them is warming the planet. That is not just an environmental problem. It is a business problem.

Governments are responding with regulations, taxes, and targets. Consumers are changing their buying habits. Investors are scrutinising environmental records. A business that ignores resource use and global warming is not just being irresponsible — it is taking on serious financial and reputational risk.

This lesson covers three specification requirements: global warming, scarce resources, and recycling. By the end, you will be able to analyse these issues from a business perspective and write exam answers that reach the top mark bands.

2. Core Concepts: Global Warming, Scarce Resources, and Recycling

Start with global warming. When businesses burn fossil fuels — to power factories, heat offices, or run delivery fleets — they release carbon dioxide and other greenhouse gases. These gases trap heat in the atmosphere, raising global temperatures over time. The scientific consensus is clear, and governments worldwide have committed to reducing emissions through legislation and international agreements such as the Paris Agreement.

Now consider scarce resources. Oil, copper, rare earth metals, and even fresh water exist in finite quantities. As global demand rises — driven by population growth and industrialisation — supplies shrink and prices rise. A business that depends heavily on a scarce resource faces unpredictable cost increases and potential supply disruptions.

Recycling connects directly to both issues. When a business recycles materials — aluminium, paper, plastic, glass — it reduces its dependence on virgin raw materials, cutting both costs and environmental impact. Recycling also reduces the volume of waste sent to landfill, which itself produces methane, a potent greenhouse gas.

These three concepts are deeply linked. Scarce resources drive up production costs. Burning those resources contributes to global warming. Recycling reduces both problems simultaneously. Examiners expect you to show these connections — not treat each concept as a separate, isolated topic.

3. How Businesses Respond: Costs, Benefits, and Trade-offs

Businesses have a range of options when responding to environmental pressures. Some act because they genuinely believe it is the right thing to do — this is sometimes called ethical behaviour. Others act because the financial case is compelling: lower energy bills, reduced waste costs, access to green subsidies, or avoiding carbon taxes.

The key responses include switching to renewable energy sources, redesigning products to use fewer materials, sourcing from sustainable suppliers, and implementing recycling programmes in production and offices. Each response carries both costs and benefits, and the balance depends on the size of the business, its industry, and the regulatory environment it operates in.

The chart above illustrates that switching to renewable energy offers the largest potential cost saving at 22%, followed by energy efficiency upgrades at 18%. This data challenges the common assumption that environmental action is always expensive — in many cases, it reduces operating costs significantly over the medium to long term.

However, the upfront investment can be substantial. Installing solar panels, upgrading machinery, or redesigning packaging all require capital expenditure before any savings are realised. For a small business with limited cash flow, this creates a genuine barrier. This is where the short-term versus long-term trade-off becomes critical in an exam evaluation.

4. Stakeholder Perspectives on Environmental Responsibility

Different stakeholders view environmental responsibility very differently, and understanding these perspectives is essential for top-band evaluation answers. Shareholders may initially resist environmental spending if it reduces short-term profits. However, many institutional investors now actively seek businesses with strong environmental credentials, recognising that poor environmental practice creates long-term financial risk.

Customers increasingly factor environmental behaviour into their purchasing decisions. Research consistently shows that younger consumers in particular are willing to pay a premium for products from businesses with strong environmental records. A business that is seen to be damaging the environment risks losing market share to more responsible competitors.

Employees are also stakeholders worth considering. Many workers — particularly graduates entering the job market — prefer to work for organisations whose values align with their own. A strong environmental reputation can therefore help a business attract and retain talented staff, reducing recruitment costs over time.

The government acts as both a regulator and an incentive provider. On one hand, it imposes carbon taxes, landfill taxes, and emissions regulations that increase costs for businesses with poor environmental practices. On the other hand, it offers grants, tax relief, and subsidies to businesses that invest in renewable energy or sustainable production methods.

Worked example: Calculating Carbon Tax Cost for a Manufacturing Business

GreenForge Ltd is a UK manufacturer. In 2024, it emitted 4,500 tonnes of CO2. The government carbon tax rate is £25 per tonne. Calculate GreenForge's carbon tax liability for 2024.

1. Carbon Tax Cost = Tonnes of CO2 emitted × Tax rate per tonne — Write the formula first — this earns a method mark even if you make an arithmetic error later.
2. Carbon Tax Cost = 4,500 × £25 — 4,500 tonnes is the emissions figure; £25 is the tax rate per tonne. Both values come directly from the question.
3. 4,500 × 25 = 4,500 × 20 + 4,500 × 5 = 90,000 + 22,500 = £112,500 — Breaking the multiplication into two parts reduces arithmetic errors. Always show your working.
4. Carbon Tax Cost = £112,500 per year — This is a significant operating cost. If GreenForge reduced emissions by 1,000 tonnes through energy efficiency, it would save £25,000 annually — making the business case for investment clear.

Answer: GreenForge Ltd's carbon tax liability for 2024 is £112,500. Reducing emissions would directly lower this cost, strengthening the financial case for environmental investment.

5. Case Study Application: Applying Theory to a Real Business Context

Consider the case of a large UK supermarket chain — call it FreshMart. FreshMart operates 600 stores, runs a fleet of 2,000 delivery lorries, and sources products from over 50 countries. Its environmental footprint is enormous. In 2023, FreshMart announced a target to reach net zero carbon emissions by 2040 and committed to ensuring that 80% of its own-brand packaging would be recyclable by 2025.

From a business perspective, these commitments serve multiple purposes. They reduce FreshMart's exposure to future carbon taxes, which are expected to rise significantly. They respond to growing consumer demand for sustainable products. They also help FreshMart attract investment from funds that apply environmental, social, and governance (ESG) criteria when selecting companies to back.

However, the transition is not without cost. Switching to recyclable packaging often costs more per unit than standard plastic. Electrifying a lorry fleet requires substantial capital investment in both vehicles and charging infrastructure. In the short term, these costs reduce profit margins — creating tension with shareholders who prioritise immediate returns.

Worked example: Evaluate Whether FreshMart Should Invest in Reducing Its Carbon Footprint

FreshMart is considering investing £50 million over five years to reduce its carbon footprint. This includes switching to electric delivery vehicles and installing solar panels on all stores. Evaluate whether this is the right decision for FreshMart. [12 marks]

Method: Stakeholder Analysis + Short-term vs Long-term Evaluation

1. Reduced carbon tax liability; lower long-term energy costs from solar panels; improved brand reputation attracting environmentally conscious customers; access to ESG investment funds. — Start with the strongest arguments for the decision, using specific details from the scenario.
2. If solar panels reduce energy costs by 20% and FreshMart's annual energy bill is £30 million, annual savings = £30m × 0.20 = £6 million. Over five years: £6m × 5 = £30 million in savings. — Using numbers — even estimates — demonstrates analytical depth and earns application marks.
3. £50 million upfront cost reduces short-term profit; shareholders may demand dividends rather than capital investment; electric lorry infrastructure is still developing, creating operational risk; payback period may exceed five years. — A balanced answer must address the risks and limitations, not just the benefits.
4. On balance, the investment is likely the right decision for FreshMart in the long term, given rising carbon taxes, growing consumer pressure, and the scale of potential energy savings. However, the business should phase the investment to manage cash flow and communicate the long-term rationale clearly to shareholders. — The conclusion must weigh both sides and reach a clear, justified position — this is what separates Level 3 from Level 4 responses.

Answer: FreshMart's £50 million environmental investment carries significant short-term costs but offers compelling long-term benefits. Reduced energy bills from solar panels could save approximately £6 million per year, partially offsetting the investment within the five-year period. Rising carbon taxes mean that inaction also carries a growing financial cost. From a stakeholder perspective, customers and ESG investors are likely to respond positively, strengthening FreshMart's competitive position. However, shareholders focused on short-term returns may resist the capital outlay. On balance, the investment is justified given the scale of FreshMart's operations and the direction of government policy — but phased implementation would reduce financial risk and maintain shareholder confidence.

6. Exam Technique: Writing Top-Band Answers on Environmental Topics

Environmental questions in AQA GCSE Business Studies are almost always evaluation questions — they ask you to 'evaluate', 'discuss', or 'recommend'. That means the examiner is not looking for a list of environmental facts. They want to see you weigh up arguments, consider different stakeholders, and reach a justified conclusion.

The most common mistake students make is treating environmental responsibility as purely positive. In reality, there are genuine trade-offs. A business that invests heavily in sustainability may face lower short-term profits, shareholder pressure, or competitive disadvantage if rivals do not follow suit. Acknowledging these tensions is what separates a Level 2 answer from a Level 4 answer.

A second common mistake is writing about the environment in general terms without connecting it to the specific business in the question. Always anchor your answer to the case study. If the question is about a manufacturing firm, discuss how that firm's production process contributes to emissions. If it is a retailer, focus on packaging, transport, and supplier sourcing.

Worked example: Writing a PEEL Paragraph on Recycling for an Exam Question

Explain one benefit and one drawback of a business introducing a recycling programme. [6 marks]

Method: PEEL Paragraph Structure

1. One benefit of introducing a recycling programme is that it can reduce the business's raw material costs. — Start with a clear, specific point — not a vague statement like 'it helps the environment.'
2. By reusing materials such as aluminium or paper rather than purchasing virgin resources, the business reduces its spending on inputs. This is particularly valuable when raw material prices are volatile due to scarcity, as recycling provides a more stable and cost-effective supply. — Link the benefit to a business consequence — cost reduction, supply stability. This earns the 'explain' marks.
3. However, setting up a recycling programme involves upfront costs, including collection infrastructure, staff training, and potentially new equipment. — The 'however' signals to the examiner that you are providing a balanced answer.
4. For a small business with limited capital, these initial costs may outweigh the savings in the short term, making the programme financially unviable without government grants or subsidies. — Contextualising the drawback — here, by business size — shows the kind of nuanced thinking that earns top marks.

Answer: One benefit of a recycling programme is reduced raw material costs. By reusing materials such as aluminium rather than purchasing virgin resources, the business lowers its input costs and reduces exposure to price volatility caused by resource scarcity. However, a drawback is the upfront investment required for collection systems and staff training. For a small business with limited cash flow, these initial costs may outweigh short-term savings, making the programme difficult to justify without external financial support such as a government grant.
