Mass Timber Construction is touted as construction’s wonder material. …Life Cycle Analyses investigating GHG emissions appear to overwhelmingly favour wood over concrete and steel. …However, perhaps it’s time to dial down some of MTC’s exuberant rhetoric. …Trees and oceans together absorb 50 per cent of global atmospheric carbon.
