Internal research shared by the Green Party suggests that the Labour Party faces a significant electoral risk regarding its stance on North Sea drilling. According to the analysis, up to 50 Labour-held seats could be vulnerable to the Green Party in the next general election if the government permits new oil and gas exploration. The report highlights that these specific constituencies contain a high concentration of voters who prioritize aggressive climate action, particularly in the wake of recent global heatwaves and environmental concerns.

Among the seats identified as potentially at risk are those held by prominent Labour figures, including allies of Andy Burnham such as Louise Haigh. The Green Party’s findings argue that these voters are looking for "bold action" on the climate crisis and that a failure to align with these expectations could lead to a loss of support. While the research frames the potential losses as a direct consequence of environmental policy decisions, it remains an internal projection from a political rival rather than an independent electoral study. The Labour Party has not yet provided a formal response to these specific projections, and the data relies on the assumption that voters will prioritize climate policy over other economic or social issues when casting their ballots.
