Environment & Sustainability Guide in Cook Islands
Air quality, green spaces, and environmental policies
Air Quality Index
Air quality in the Cook Islands is excellent due to minimal industrial activity, transportation emissions, and population density. Database shows stable 6-month AQI trend with no PM2.5/PM10 data, reflecting pristine conditions. No major pollution sources identified; occasional biomass burning from cooking has negligible impact.
Water Quality
Water quality is good, with rainwater harvesting as primary source treated to WHO standards. Coastal groundwater faces salinization risks from sea level rise. 95% population has access to improved water; monitoring by Te Ipukarea Society detects low contamination levels from tourism waste.
Recycling System
Recycling infrastructure is developing with community programs on Rarotonga focusing on plastics and aluminum cans. No national rate available; efforts supported by Te Maeva Nui clean-up campaigns. Waste shipped to New Zealand for processing due to limited landfill space.
Green Spaces
Cook Islands protects 50% land area as forest and 80% EEZ as marine reserves. Key sites include Rarotonga highlands and Suwarrow Atoll National Park. Forest coverage stable at ~50%, supporting endemic birds amid invasive species threats.
Environmental Policies
Strong policies include National Environment Strategic Plan 2023-2027 targeting 50% renewable energy by 2030 and zero plastic imports by 2025. Paris Agreement signatory with NDC updated 2021 aiming for 60% GHG reduction. Suva Declaration on plastic pollution implemented.

Sustainability Initiatives
Solar PV expansion on 7 islands; 20% renewable mix in 2023 aiming for 50% by 2030 via New Zealand aid. Hybrid systems reduced diesel imports 15%.
80% EEZ protected since 2018; Pukapuka marine sanctuary bans commercial fishing, boosting fish stocks 30%.
Single-use plastic ban phased 2018-2025; community recycling hubs process 40% aluminum cans.
