Air quality, green spaces, and environmental policies in Jersey

Jersey maintains good environmental quality with a stable air quality trend and high-quality drinking water well within safety limits. Greenhouse gas emissions have decreased 48% since 1990, supported by commitments to net zero by 2050. The island faces climate challenges including warmer temperatures, increased rainfall, potential droughts, and sea level rise risks due to its coastal location. Conservation protects diverse habitats like Ramsar wetlands.

Air Quality Index

Good

7.5/10

Stable trend

Jersey's air quality trend is stable per database records. No specific AQI or PM data available, but emissions reductions suggest good conditions with limited industrial pollution.

Water Quality

Excellent

9.0/10

Jersey Water supplies safe drinking water, averaging 70% below EU/UK limits. Focus on PFAS treatment and pollution protection around reservoirs to meet upcoming stricter standards.

Water is confirmed safe by Independent Scientific Panel; preparations for new PFAS regulations underway.

Recycling System

Recycling infrastructure supports Jersey's sustainability efforts, though specific rates unavailable in database. Waste management aligns with emissions reduction and environmental policies.

Green Spaces

Jersey features diverse habitats including Ramsar wetlands, coastal heaths, woodlands, dunes, and marine areas like seagrass beds and reefs. These support rich biodiversity.

Forest Coverage: 20.0%

National Parks: 0

South east coast and offshore reefs designated Ramsar site of international importance for wetlands.

Environmental Policies

Jersey commits to 68% emissions reduction by 2030, 78% by 2035, net zero by 2050 from 1990 baseline via Paris Agreement. Incentives for electric vehicles supported transport emission cuts.

Key Policies:

•Net Zero by 2050
•Paris Agreement signatory
•Electric vehicle incentives

Renewable Energy: Emissions trajectory includes energy supply reductions.

Natural Disaster Risk

MODERATE

Jersey faces risks from storms, floods, and coastal erosion. Temperate maritime climate with mild extremes but increasing weather variability.

Climate Change Impacts: Mean air temperature 2024: 12.94°C (7th warmest, above 1991-2020 avg 12.39°C). Rainfall 2024 slightly above 918.2mm avg, 190 rain days (above 188.2 avg). Sea temp 13.71°C (above 12.73°C avg). GHG emissions down 48% since 1990 but transport 43% of total. Forecasts: severe droughts up to 8.6M litres/day shortage in 10 years. Increased moisture capacity with warming raises flood risk; coastal location vulnerable to sea level rise.

Sustainability Initiatives

Renewable Energy

Emissions reduction targets: 68% by 2030, net zero by 2050. Energy supply emissions decreased significantly since 1990.

Waste Management

Transport emissions down 23% since 1990; EV charger incentives continue post-2024 purchase scheme.

Water Management

PFAS treatment pilots and reservoir protection to counter drought risks and pollution.
