2023 has been a landmark year for climate policy and international cooperation. The UN Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report (AR6), which provides critical insights into the current state of climate change. The report emphasizes that climate impacts on people and ecosystems are more severe and widespread than previously anticipated4.
Approximately half of the global population faces severe water scarcity for at least one month each year, and higher temperatures are facilitating the spread of diseases like malaria and Lyme disease. To build resilience against these impacts, substantial financial investments in adaptation measures are necessary, particularly in developing countries. The IPCC estimates that $127 billion per year will be needed by 2030, increasing to $295 billion per year by 2050. However, current adaptation funding is only a fraction of these amounts.
Whilst current spending falls significantly short of these needs, 2023 saw a notable milestone with the $100 billion annual pledge to support countries affected by climate impacts being met for the first time.
The transition to a low-carbon economy gained significant momentum in 2023. According to the International Energy Agency (IEA), global investment in clean energy technologies surged by 70%, reaching $200 billion5. The electric vehicle (EV) market also experienced significant growth. The IEA's Global EV Outlook report noted a 35% increase in global EV sales in 2023, with EVs expected to contribute to 20% of global care sales in 20246.
In electricity generation, the IEA forecasts a rapid expansion of low-emission power sources. Global power demand is expected to grow at an average rate of 3.4% over the next three years, primarily driven by demand outside advanced economies. The projected growth in power demand is anticipated to be met entirely by additional low-carbon power capacity, including wind, solar, hydro, and nuclear power.
By 2026, these low-emission sources are anticipated to account for almost half of the world's electricity generation, up from 39% in 20237.
