RBWM demands detailed carbon offset plans for Heathrow third runway emissions

The Royal Borough of Windsor and Maidenhead (RBWM) is calling for Heathrow to provide detailed carbon offset plans before any third runway is approved. The council wants to see how the airport intends to compensate for the additional emissions the expansion would create. This is a local government pushing for concrete climate accountability tied to a major infrastructure project. For anyone tracking carbon markets and offset quality, this is a test case. The demand for specific offset plans means RBWM is not accepting vague net zero pledges. They want to see the actual mechanism, the type of credits, and the verification behind them. This could set a precedent for how local authorities engage with airport expansion and carbon accounting.
