Notes

Variants of this metric include TNFD additional disclosure metric A2.3: “For example:
• Percentage of light fixtures that fully cut-off or are fully shielded, or are below 60W;
• Intensity of outdoor lighting (lumen/ha); and
• Average noise level on-site during noisiest part of the day, an hour either side of sunrise and an hour either side of sunset (dB); distance from nearest habitat (m).”
