Climate change targets are necessarily ambitious. Weather patterns that were once considered freakish are now occurring regularly across the world, with wildfires and flooding happening at a frightening rate. Watching these scenes unfold, it can often feel like the task of turning the tide is insurmountable. A more ambitious approach is needed from the government and businesses. But what the rest of us do will also be crucial in driving this transition, and that requires more meaningful consumer engagement, with more reliable information and support provided for the choices we make.
