As councils work towards net zero, many continue to face residual emissions despite significant carbon reduction efforts. While green assets such as parks, woodlands, grasslands and wetlands already remove carbon from the atmosphere, there is currently no nationally recognised methodology for consistently quantifying and reporting this contribution. In response, East Herts District Council commissioned HCCSP to develop a practical and transparent approach that could support annual emissions reporting and help establish more robust net emissions baselines.
In August 2026, HCCSP launched its Green Asset Carbon Sequestration Tool, enabling local authorities in Hertfordshire to estimate and report the carbon value of their green assets in a consistent and evidence-based way.
