Surfaces like tarmac can turn housing into heat traps, leaving homebuyers vulnerable to unliveable conditions.\r\n\r\nTrees provide vital cooling, dropping local surface temperatures by up to 15°C through shade and evapotranspiration. We ask Parliament to mandate 25% tree canopy targets, reducing NHS costs and relieving communities of unbearable heat.","committee_note":"","state":"open","signature_count":77,"closing_date":"2027-04-12","created_at":"2026-09-14T17:37:43.698Z","updated_at":"2026-10-14T06:06:50.000Z","rejected_at":null,"opened_at":"2026-10-12T10:58:28.659Z","closed_at":null,"moderation_threshold_reached_at":"2026-09-14T18:57:30.000Z","response_threshold_reached_at":null,"government_response_at":null,"debate_threshold_reached_at":null,"debate_scheduled_on":null,"scheduled_debate_date":null,"debate_outcome_at":null,"creator_name":"Noah
