England's Poorest Communities Face Disproportionate Loss of Green Spaces Under Planning Law Changes

The Growing Nature Divide in England

A new report commissioned by wildlife and environmental NGOs reveals that proposed changes to England's planning laws will further deprive the country's poorest communities of access to green spaces and biodiversity. The findings highlight how exemptions to biodiversity net gain rules will disproportionately affect areas already suffering from "nature poverty," with over 7.4 million people, including 1.4 million children under 15, living in areas completely devoid of immediate biodiversity.

Loopholes in Biodiversity Protection

Biodiversity net gain rules, introduced in 2024, mandated that most new developments in England deliver at least a 10% increase in biodiversity value. This policy was considered world-leading and was referenced at international climate talks. However, the Labour government has introduced exemptions for housebuilders after lobbying from the sector, including exemptions for sites of 0.2 hectares and under, and a proposed exemption for brownfield sites up to 2.5 hectares.

The Economic Impact of Green Space Loss

The report quantifies the potential biodiversity loss from the small sites exemption alone, estimating it could mean the loss equivalent to nearly 11,000 mature trees or 400 football pitches of wildflower meadow over one year. In the most deprived areas, four in five (82%) planning applications are for small sites under 0.2 hectares, making these communities particularly vulnerable to the exemptions.

Environmental Inequality Across England

The research reveals stark disparities in access to nature across different socioeconomic groups. In the most deprived 20% of neighborhoods, almost a third of people have highly restricted biodiversity access – nearly three times the rate of the most affluent communities. Four times as many potential brownfield homes are concentrated in the poorest fifth of England's population compared with the richest fifth.

London's Extreme Nature Divide

In London, Croydon shows the most extreme inequality in access to nature, with its most affluent neighborhoods enjoying 73% biodiversity access against just 24% in the most deprived – a 49-percentage-point gap within a single local authority. This pattern of environmental inequality is not driven by rural-urban divides but by extreme disparities within towns and cities.

Future of Environmental Protection in England

The coalition of charities is calling for the brownfield site exemption to be scrapped and for the government to enact a legally binding five-year policy lock-in to protect biodiversity net gain from further detrimental changes. Environmental experts warn that weakening these rules not only harms the environment but also undermines the government's own housing ambition of providing safe and decent homes for all, as nature-integrated development reduces flood risks and brings positive health outcomes.
