Last month, the scientific community confirmed what most of us already know. Climate change is here. Left unabated, the frequency and intensity of its impacts will only get worse. We are already seeing loss of lives and the effect on macroeconomic stability. Taking bold action through the introduction of a global carbon price is essential.
Momentum on climate change is picking up, with governments and companies pledging to get to net zero carbon emissions by 2050 or earlier. Many have already adopted a range of initiatives. Members of the World Trade Organization have, since 2009, formally notified more than 4,500 climate-related measures, from direct taxes to regulation, and discussed their trade implications.
