What this dot point is asking
SCSA wants you to connect the flows of globalisation to their environmental costs, explain why those costs are spatially displaced, and evaluate management responses. A strong answer links the network concept directly to environmental outcomes.
Emissions from global transport
The freight that underpins global trade runs on carbon-intensive transport. International shipping and aviation together produce a significant share of global greenhouse emissions, and because they cross borders they have historically fallen outside national targets. The sheer scale of containerised trade means that moving goods around the world carries a large and growing climate footprint.
Displaced pollution and the pollution of production
When manufacturing relocates to lower-cost economies, the pollution of production relocates with it. High-income consumers effectively offshore their environmental impact: the emissions and pollution embedded in their goods are released in producing countries such as China and Vietnam. This is why a country can appear to cut its own emissions while its consumption-based footprint stays high.
Resource extraction and ecosystems
Global demand drives resource extraction with heavy local impact: deforestation for palm oil and soy, water depletion, mining disturbance, and overfishing of shared seas. Because demand and impact are separated, consumers rarely see the environmental cost of what they buy.
Managing transboundary impacts
Because global networks separate cause from effect across borders, management depends on international cooperation. Responses include the Paris Agreement on emissions, the Basel Convention restricting hazardous-waste exports, agreements limiting shipping and aviation emissions, and private supply-chain standards and certification such as sustainable palm oil or timber. Consumer awareness and product labelling shift some pressure back toward the consuming end.
A balanced answer recognises that the environmental costs of globalisation are real and unevenly distributed, that they are hard to govern because they cross jurisdictions, and that effective responses must act along the whole network rather than within single countries.
The Australian dimension
Australia sits at the producing end of several global environmental flows. Its iron ore, coal and gas exports embed large emissions that are released both in extraction and, ultimately, in the steelmaking and power generation of importing countries, raising the contested question of who is responsible for emissions from exported fossil fuels. Australian agriculture exports embed significant virtual water from a dry continent. At the same time Australia is a consumer that offshores manufacturing emissions to Asia and exports some waste abroad. This dual role makes Australia a useful case for showing that environmental responsibility in a globalised economy cannot be neatly assigned to one country, and that consumption-based accounting changes who appears responsible for a given impact.

A 12 mark evaluation must link flows to impacts and judge management responses.
Impacts. Connect each flow to a consequence: shipping and aviation emit greenhouse gases that historically escaped national targets; relocating manufacturing displaces pollution to producing countries so consumption-based footprints stay high; e-waste flows concentrate toxic harm in poorer regions; and resource extraction for traded goods drives deforestation and water depletion.
Why management is hard. Because global networks separate cause from effect across borders, no single country controls the whole problem, so governance depends on cooperation.
Evaluating responses. The Paris Agreement, the Basel Convention on hazardous waste, shipping and aviation emissions agreements, and private certification such as sustainable palm oil all act on parts of the network, but enforcement is uneven and impacts continue.
Judgement. Conclude that effective action must address the whole network, and that current responses are partial. Markers reward impacts tied to flows and a real evaluation of management.
WACE 20246 marksExplain how the relocation of manufacturing to lower-cost economies displaces environmental impact between countries.Show worked answer →
A 6 mark response needs the displacement mechanism and its measurement.
Mechanism. When manufacturing moves to lower-cost economies, the pollution and emissions of production move with it, so high-income consumers effectively offshore the environmental cost of their goods.
Measurement. This is why a country can appear to cut its territorial emissions while its consumption-based footprint, which counts emissions embedded in imports, stays high. Embedded carbon and virtual water are the hidden environmental flows carried by trade.
Conclude that trade shifts environmental pressure onto producing regions far from the consumers who created the demand. Markers reward the offshoring mechanism and the consumption-based or embedded-flow concept.
