• Major Facilities are Australia’s biggest industrial polluters.
• They're regulated under the Safeguard Mechanism - a law that sets limits for greenhouse gas emissions.
• Limits are called 'baselines'. Facilities are allocated individual baselines except for grid-connected electricity facilities (shown in brown), which share a sector-wide baseline.
• The general rule is baselines fall each year by 4.9%, which means facilities have to reduce their emissions. But they can meet these cuts by buying carbon credits.
