The EU plans to cut greenhouse gas emissions by 55% by 2030 compared to 1990 levels, while the US aims to reduce greenhouse gas pollution by 50-52% by 2030 from 2005 levels and to reach net zero by 2050. China aims to peak its carbon dioxide emissions by 2030 and lower its carbon dioxide emissions per unit of GDP by over 65% from the 2005 level by 2030, with a long-term goal of achieving carbon neutrality by 2060. As of 2022, the United States has reduced its greenhouse gas emissions by approximately 17% compared to 2005 levels, which is about one-third of its 2030 target (source: EPA). By 2022, the European Union has decreased its greenhouse gas emissions by around 34% from 1990 levels, which is close to 62% of its 2030 target (source: EEA). In terms of carbon intensity, by the end of 2022, China has reduced its carbon dioxide emissions per unit of GDP by about 48.4% from 2005 levels, which is near its 2030 target of around 50% (source: National Bureau of Statistics). There is still a significant gap to achieve the goal, and relevant investments need to increase substantially in the coming years.

In 2023, global energy transition investments amounted to $1.77 trillion. However, to align with the Paris-aligned Net Zero Scenario, annual investments need to nearly triple by 2030, reaching an average of $4.84 trillion per year. This increase underscores the monumental effort required to transform the global energy landscape. By 2041-2050, the necessary annual investment will rise even further to $7.59 trillion, indicating a continuous and escalating demand for financial resources to support this transition.

A closer examination of sector-specific investment needs reveals where the most significant opportunities and challenges lie.
