Which requirement does the Environment Act impose on developers?

• A. Developers must plant five trees per hectare
• B. Developers must submit a monthly impact report
• C. Developers must create a carbon neutral plan by 2030
• D. Developers must achieve a minimum 10% biodiversity increase on their sites

Answer: (D)

Biodiversity net gain is the core idea here. The Environment Act requires new developments to deliver a net improvement in biodiversity, not just avoid harm. Practically, this means developers must achieve at least a 10% increase in biodiversity on the site, using a standard metric to quantify the gains. The gains come from on-site enhancements—habitat creation, restoration, native planting, and long-term management. If on-site gains aren’t fully possible, off-site compensation can be used, but the overall net gain must still reach 10%. This net gain is secured as a planning condition and is intended to be maintained for a long period, typically around 30 years. The other options don’t reflect the Act’s main requirement, which centers on delivering biodiversity net gain rather than fixed planting quotas, monthly reports, or a carbon-neutral plan.
