New findings accentuate value of old growth forest in addressing climate change

A UK study published in December 2022 suggests carbon volume in larger trees is likely to be much higher than previously estimated.
This potentially has huge implications for the value of forests, old growth in particular, for mitigating climate change – and underlines a correspondingly much greater cost of their destruction.
The indepth study is based on 3D terrestrial laser scanning (TLS), a remote sensing technique that accurately captures the volume and mass of carbon from pulse emissions. This methodology supplants more sketchy estimates currently based on allometric models from calculation of tree diameter, which assume size and mass grow at a steady rate; these are deemed more suitable for trees less than 50 cm diameter.
