The article outlines a roadmap for rapid decarbonization, emphasizing the need to align national commitments with science-based targets to achieve the Paris Agreement's goals. It proposes a global decadal roadmap based on a "carbon law" of halving gross anthropogenic CO2 emissions every decade, complemented by immediate and scalable carbon removal efforts. The roadmap aims to achieve net-zero emissions around mid-century, limiting warming to well below 2°C. Key steps include: 1. **2017-2020: No-Brainers**: Implement proven policy instruments like carbon taxes and cap-and-trade systems, eliminate fossil fuel subsidies, and accelerate the transition away from coal. 2. **2020-2030: Herculean Efforts**: Expand carbon pricing, phase out coal, and increase investment in R&D for climate solutions. Achieve significant improvements in energy efficiency and reduce emissions from transport and buildings. 3. **2030-2040: Many Breakthroughs**: Electrify all sectors, develop carbon capture and storage (CCS) technologies, and scale up sustainable agriculture practices. 4. **2040-2050: Revise, Reinforce**: Refine and amplify successful strategies, achieve net-zero emissions globally, and ensure stability and resilience through continued innovation and governance. The authors stress the importance of aligning climate stabilization with economic development, human rights, democracy, and peace, and suggest that a carbon roadmap should be a central focus at the UN Security Council.The article outlines a roadmap for rapid decarbonization, emphasizing the need to align national commitments with science-based targets to achieve the Paris Agreement's goals.
