However, while the rapid expansion of 2050 targets and long-term strategies is encouraging, commitments to act by 2030 are also critical. Countries representing well over half of the global economy, including nearly all the G7 countries, have already put forward strong 2030 NDCs. Leadership and action by these countries will support development of new and more affordable climate technologies and support enhanced diplomatic momentum to encourage global action toward reaching sufficient levels of near-term action. But the United States, EU, UK, Japan, Canada, Republic of Korea, South Africa, and other ambitious major economies cannot do it alone. Strong 2030 NDCs will be required by all G20 economies to cut global emissions by at least 40% by 2030. Enhanced action by all G20 members to adopt high ambition 2030 NDCs and mid-century net-zero commitments could reduce warming by over 0.5°C and keep 1.5°C within reach [108]. Globally, this is the moment for all the world's major economies to act to rapidly reduce emissions to meet ambitious 2030 NDC targets and to develop and communicate strategies to achieve ambitious 2050 net-zero goals. diverse stages of identifying and committing to similar net-zero targets by mid-century [105] [106] [107].
