Which company did Greenpeace expose as Australia's largest climate polluter, leading to a court case about energy use?

• A. BHP
• B. AGL
• C. Rio Tinto
• D. Woolworths

Answer: (B)

The idea being tested is how a company's energy choices translate into its greenhouse gas impact and why that matters for accountability. Greenpeace highlighted AGL Energy because its coal-fired power plants make it the largest source of CO2 emissions in Australia. Coal power is the most carbon-intensive part of electricity generation, so the company operating the biggest coal fleet ends up contributing more to national emissions than others, even if those other companies (like BHP or Rio Tinto) are large emitters in their own right. The exposure drew attention to energy use and emissions reporting, helping spark a court case about how energy consumption is measured and disclosed. Woolworths, while a contributor through its supply chain and operations, does not represent the single largest climate polluter in the way Greenpeace identified AGL at that time.
