International Energy Agency: CO2 Emissions Report 2022
概要
A new analysis released today by the International Energy Agency shows that in 2022, in the midst of the global energy crisis, the use of solar energy, wind energy, electric vehicles, and heat pumps will increase, coupled with the improvement of energy efficiency , and the growth of coal and oil will be limited to a certain extent. As a result, global energy-related CO2 emissions grew by less than 1%, below expectations.
The analysis report entitled "Carbon Dioxide Emissions in 2022" shows that although last year's emission growth was far lower than the abnormal growth of more than 6% in 2021, emissions still showed an increasing trend, which is not conductive to sustainable development, and more measures are needed. Strong action to accelerate the clean energy transition and put the world on track to meet its energy and climate goals.
Analysis report helps COP28
The report is the first in a new series of "Assessments of the Global Energy Transition", which brings together the latest analysis from the International Energy Agency and is freely available to the public to support progress ahead of the 28th United Nations Climate Change Conference ( COP28) this November. First global assessment.
The global CO2 emissions figures in the report are based on the IEA's detailed analysis of different regions and different fuels, drawing on the latest official national data and publicly available energy, economic and weather data. The report also covers carbon dioxide emis sions from all energy combustion and industrial processes, and also includes information on methane and nitrogen oxide emissions, presenting a complete picture of energy-related greenhouse gas emissions in 2022.
Clean energy helps reverse emissions trend
The report shows that in 2022, global energy-related carbon dioxide emissions will increase by 0.9%, or 321 million tons, hitting a new high of over 36.8 billion tons.
The rise in emissions was significantly slower than global economic growth of 3.2%, suggesting a return to a decade-long trend. This trend will be interrupted in 2021 when there is a rapid and high-emissions economic rebound following the COVID-19 crisis . Despite extreme weather events such as droughts and heat waves, and an unusually large number of nuclear power plant outages leading to rising emissions, 550 million tons of CO2 emissions were avoided through increased deployment of clean energy tech noologies.
Fatih Birol, executive director of the International Energy Agency, noted that the energy crisis has not led to a sharp increase in global emissions, as initially feared, thanks to a significant increase in renewable energy, electric vehicles, heat pumps and energ y-efficient technologies . Without clean energy, growth in carbon dioxide emissions would have nearly tripled.
He warned: "However, fossil fuel emissions are still increasing, hindering efforts to achieve global climate goals. International and national fossil fuel companies, with record operating revenues, need to shoulder their own burdens in line with their publicly committed cl imate goals. Responsibility . It is important that they revisit strategies to ensure they are aligned with meaningful emissions reductions."
Coal and oil emissions rise
CO2 emissions from coal rose by 1.6% as the global energy crisis continued to spur a switch from natural gas to coal in Asia, with a small increase also in Europe. While the increase in coal emissions is only about a quarter of the increase in 2021 , it is still well above the average growth rate of the past 10 years.
After the Russian-Ukrainian conflict broke out, natural gas supply continued to tighten, coupled with European companies and people reducing the use of natural gas, the carbon dioxide emissions of natural gas fell by 1.6%. Coal emissions have grown more t han that, though.
However, oil's CO2 emissions grew even more than coal, up 2.5%, but still below pre-pandemic levels. Air travel continues to rebound from the nadir of the pandemic, with the airline industry accounting for about half of the year-over-year increase in oil emissions.
Emissions by country
In China, emissions are roughly flat in 2022 due to lower industrial and transport emissions due to strict anti-epidemic measures and a decline in construction activity.
Emissions in the European Union fell by 2.5%, largely due to the deployment of renewable energy, resulting in coal use not being as high as some observers had expected. A milder early winter in Europe and energy-saving measures in response to the Russia- Ukraine conflict also helped.
Meanwhile, in the US, emissions rose 0.8% as buildings increased energy use to cope with extreme temperatures.
Emissions from emerging and developing Asia, excluding China, rose by 4.2%, reflecting rapid growth in their economies and energy demand.
