The International Monetary Fund (IMF) has warned that to achieve net-zero emissions by 2050, green investment will need to increase fivefold, from $900 billion in 2020 to $5 trillion per year in 2030. Emerging and developing countries need US$2 trillion per year, a fivefold increase from 2020. The private sector will need to provide much of the financing for these low-carbon investments. The IMF guidance comes ahead of the COP28 conference in Dubai, where policymakers and governments will discuss future climate mitigation strategies. More than 80% of the 50% emissions reduction target by 2030 can be achieved through existing technologies.
