Should we be reaching net zero by 2025, 2030 or 2050? Are these targets a useful driver to deliver the changes needed or an unnecessary distraction from the important question of what kinds of policies and actions we need to put in place?
Politicians, activists and newspaper editors have all called on us to follow the science. The SMC decided to run a briefing establishing what the science says about how, and how fast, we reach net zero in order to limit climate change consistent with the temperature goals set in the Paris Agreement.
