In our opinion as Net Zero Consultancy, the most potent weapon we have against climate catastrophe is net zero emissions. Switching to net-zero emissions is a robust solution with advantages for the economy, society, health, and the environment. Inaction puts the world at risk of catastrophic climate change, which includes extreme weather, rising sea levels, species extinction, and disruptions to food and water supply. The ISO Net Zero Guidelines (IWA 42:2022) describe net zero as "a condition in which human-caused residual greenhouse gas emissions (GHG) are balanced by human-led removals over a specified period and within specified boundaries," even though definitions of net zero differ. A sophisticated process, including pollution reductions, offsetting, and cutting-edge technology, is required to achieve this equilibrium. Reducing emissions at their source and using carbon dioxide removal to counterbalance leftover emissions are two ways to reach a world with net-zero emissions.
