Quick questions on Environmental management policies in Australia (HSC Economics Topic 4)

Use a price signal to make the polluting choice more expensive, or the clean choice cheaper, and let firms choose HOW to respond. Australia's main example is the reformed Safeguard Mechanism (from 2023), which sets a baseline for each of the roughly 200 largest industrial facilities that declines by about 4.9 percent a year to 2030; facilities that exceed their baseline must buy Safeguard Mechanism Credits or Australian Carbon Credit Units (ACCUs), while facilities that beat their baseline can sell credits. On the supply side, subsidies for renewables (e.g.

Set a mandatory legal limit that must be met regardless of cost. Examples: the New Vehicle Efficiency Standard (from 2025), a mandatory declining fleet-average CO2-per-km limit for new light vehicles sold in Australia, with financial penalties for manufacturers that exceed it; state Environment Protection Authority licence conditions capping emissions or discharges from individual facilities; mandatory environmental impact assessments before major developments proceed.

Set a measurable goal and a timeframe, usually alongside a global commitment. Australia's Climate Change Act 2022 legislates a target of a 43 percent reduction in emissions below 2005 levels by 2030, and net zero by 2050; this operationalises Australia's nationally determined contribution (NDC) under the Paris Agreement (2015), the main global framework under which nearly 200 countries pledge and periodically update their own emissions targets.

Generic claims ("the government has environmental policies") score far less than a named, dated scheme (Safeguard Mechanism, 2023 reform; New Vehicle Efficiency Standard, from 2025; Climate Change Act 2022).

A legislated target (43 percent by 2030) is the destination; the Safeguard Mechanism, renewable subsidies and direct regulation are the vehicles. Naming a target alone, with no instrument, caps an "evaluate effectiveness" answer.

MPC below MSC, demand unchanged, market quantity to the right of (higher than) the social optimum. Label curves OUTSIDE the lines and mark both intersection points.

Replace "the government regulates pollution" with "the reformed Safeguard Mechanism (from 2023) requires the largest roughly 200 industrial emitters to cut baselines by about 4.9 percent a year to 2030." A dated, named scheme earns marks a vague claim cannot.
