England’s poorest areas face deepest cuts to green space under planning law changes, report finds

Exclusive : New loopholes for developers will exacerbate extreme environmental disparities, charity coalition warns

The poorest and most nature-deprived communities in England will be further left behind in their access to green spaces if proposed changes to planning laws go ahead, a report finds.

More than 7.4 million people in England live in areas completely devoid of immediate biodiversity, including 1.4 million children under 15, the report commissioned by a number of wildlife and environmental NGOs says.

The severe nature poverty is driven not by the rural-urban divide, but by extreme environmental disparities within towns and cities, and new “loopholes” for developers will exacerbate it, it says.

Biodiversity net gain rules, introduced in 2024, made it mandatory in England for most new developments to deliver at least a 10% increase in biodiversity value. The UK is one of the most nature-depleted countries in the world, and the landmark policy was intended to help nature recovery. It was considered world-leading, referenced at Cop16 in Cali, Colombia, and replicated in countries such as Saudi Arabia, the Netherlands, and India.

But the Labour government, which has a target to build 1.5m homes by the end of this parliament, introduced a series of exemptions for housebuilders after lobbying from the sector. These include an exemption for sites of 0.2 hectares (0.5 acres) and under, and a proposed exemption, now out to consultation, on removing biodiversity net gain rules for brownfield sites up to 2.5 hectares.

The coalition of charities warned the exemptions would hit the poorest communities in England, depriving them of access to nature while more affluent people continue to enjoy green environments.

The report, published on Thursday, shows that in the most deprived areas four in five (82%) planning applications are for small sites under 0.2 hectares. Across one year, the report says the exemption for small sites could mean the loss of biodiversity equivalent to nearly 11,000 mature trees or 400 football pitches of wildflower meadow.
