TNFD EH.A2.0; RE.A2.0; CM.A2.1
Contribution to light pollution, measured, for example, by: • Number and proportion (%) of outdoor lights by backlight, uplight and glare (BUG) rating; • Number and proportion (%) of outdoor lights above 2700K; • Total outdoor lighting (lumen and lumen/ha); • Total (m2 ) and proportion (%) of area with nighttime lighting; and/or • Number and proportion (%) of outdoor lights that are kept on at night; and number and proportion (%) of outdoor lights that are and are not dimmed at night, by degree of dimming.
TNFD EH.A2.1; CM.A2.2
Contribution to noise pollution, measured, for example, by: • Average noise level and/or frequency (dB, Hz) across the 2-hour periods centred on sunrise and sunset before work on the site started (baseline), and during operations, on-site and/or in the nearest noise sensitive habitat to the most significant noise source; and/or • Average noise level and/or frequency across the day (dB, Hz), before the work on the site started (baseline), and during operations, on-site and/or in the noise-sensitive habitat nearest the most significant noise source; and/or • Average noise level and/or frequency (dB, Hz) before work on the site started (baseline) and at the noisiest period of the day during the operations, on-site and/or in the noise-sensitive habitat nearest the most significant noise source; and/or • Number of incidents where noise level exceeded local regulatory or international standards.
Target example
[Company name] will [reduce or maintain] [light or noise] pollution at/by [target amount (lumen/ha or dB) at [target location(s)] by [target year], compared to a [baseline year] baseline.
