Review: Radical Path to Net Zero Emissions.

The Intergovernmental Panel on Climate Change (IPCC) has warned that the world is not responding strongly enough to the growing climate crisis. However, Simon Sharpe’s Five Times Faster offers hope with a plan for scaling up cuts in global greenhouse gas emissions to reach net zero by 2050 and avoid a rise in global temperature of more than 1.5C. Sharpe argues that as the global economy grows and energy use increases, we need to replace fossil fuels with cleaner alternatives at a much faster pace. Sharpe draws on his experience as director of economics for the UN Climate Champions team and highlights new research and analysis treating the economy as an ecosystem, recognising tipping points in the supply of, and demand for, zero-carbon technologies. Sharpe is optimistic but realistic about the degree of collaboration required between governments to achieve this.
