What You'll Learn
Fossil fuel consumption is declining
Fossil fuel consumption is indeed declining in some sectors, but it is also increasing in others. While coal consumption is falling in many parts of the world, oil and gas consumption is still growing quickly.
The transition away from fossil fuels is well underway, driven by the need to reduce air pollution, limit climate change, and strengthen energy independence. Many countries are shutting down coal-fired power stations, and the peak of fossil-fuelled electricity generation seems to be in the past. However, the transition to cleaner energy sources is not happening fast enough to meet climate goals, and fossil fuel consumption continues to play a dominant role in global energy systems.
Global fossil fuel use is projected to flatten or decline by mid-century before rising again due to increasing energy demand. This projected decline is largely driven by the decreasing consumption of coal, oil, and gas. However, it is important to note that this decline is not expected to be permanent, and fossil fuel consumption will likely increase again in the future.
While there has been progress in reducing fossil fuel consumption in some sectors, such as transportation and electricity generation, other sectors like aviation, shipping, and industry are lagging. These sectors rely heavily on fossil fuels due to the lack of widespread alternatives for jet fuel and ship diesel. Additionally, certain industrial processes, such as cement-making and plastic production, continue to contribute significantly to carbon emissions.
To accelerate the decline in fossil fuel consumption, policies and innovations are necessary. This includes the development of renewable energy sources, such as wind and solar power, as well as the adoption of electric vehicles. Additionally, demand-side and supply-side measures, such as those outlined by the ETC, can help reduce fossil fuel demand across sectors.

But aviation, shipping and industrial sectors are lagging
Fossil fuels, including coal, oil, and gas, have played a dominant role in global energy systems. However, the world needs to transition away from them due to their negative impacts, such as producing carbon dioxide (CO2) and being the largest driver of global climate change. While the consumption of fossil fuels has increased significantly over the past decades, there has been a shift from solely coal towards a combination of oil and gas. Today, coal consumption is declining in many parts of the world, but oil and gas consumption are still growing quickly.
Despite the overall decline in fossil fuel usage, some sectors, such as aviation, shipping, and industrial sectors, are lagging in this transition. Here is a more detailed look at each of these sectors:
Aviation Sector
The aviation sector accounts for a relatively small share of global emissions, but it is one of the most challenging sectors to decarbonize. Aviation emissions saw a decline during the Covid-19 lockdowns but have since recovered and are expected to surpass their 2019 levels by 2025. The sector requires technological innovations, such as the production of low-emission fuels, improvements in aircraft and engines, and operational optimization. While new aircraft can be more efficient than older models, the growth in activity has historically outpaced efficiency improvements. Demand restraint solutions are also needed to curb emissions growth.
Shipping Sector
The shipping industry is regulated by the International Maritime Organization (IMO), which has set a target of only a 50% reduction in emissions by 2050. However, the current regulatory measures focus on increasing the energy efficiency of ships rather than reducing total sector GHG emissions. As a result, carbon emissions from shipping are projected to increase by up to 50% by 2050. A complete ban on the use of fossil fuels in shipping by 2050, as recommended by the IPCC, could be a more effective approach.
Industrial Sector
The industrial sector encompasses a wide range of industries, including fossil fuel producers, manufacturers of steel, cement, and aluminum, as well as agriculture, mining, petrochemical, and construction. Currently, the industrial sector is responsible for nearly a quarter of greenhouse gas emissions. The manufacturing of cement, plastics, and petrochemicals is expected to maintain or even increase its demand for fossil fuels by the middle of the century. While the iron and steel sector is projected to see a decline in fossil fuel demand due to increased steel recycling, it still contributes significantly to harmful emissions. Transitioning away from fossil fuels in this sector could significantly reduce greenhouse gas emissions and improve human health.

The world is transitioning to clean energy
Fossil fuels, including coal, oil, and gas, have been the dominant energy source globally. However, they have severe negative impacts, including producing carbon dioxide when burned, contributing to climate change, and causing local air pollution, which leads to millions of premature deaths annually. As low-carbon energy sources, such as nuclear and renewables, become more accessible, a transition away from fossil fuels is crucial to address these issues.
While global fossil fuel consumption has increased significantly over the past decades, there are signs that this trend may be changing. Coal consumption is declining in many parts of the world, and overall, global fossil fuel use is projected to flatten or decline by mid-century. This shift is driven by the increasing adoption of clean and renewable energy sources, such as solar, wind, and electric vehicles.
The world is witnessing a transition towards clean energy, with record investments in renewable sources. The International Energy Agency has recognized solar power as the cheapest source of electricity in history. The electric vehicle market is also experiencing significant growth, which will contribute to reducing emissions from cars and trucks. Additionally, countries are taking steps to phase out fossil fuels, with many setting dates to stop selling petrol and diesel vehicles.
However, there are still challenges and areas where progress needs to accelerate. Aviation, shipping, and industrial processes continue to rely heavily on fossil fuels, and emissions from these sectors remain high. Additionally, the use of natural gas as a "bridge fuel" to replace coal may extend the lifespan of fossil fuel infrastructure. Nevertheless, the transition to clean energy is gaining momentum, with policies and commitments from governments and energy organizations driving the shift towards a more sustainable future.
To summarize, the world is indeed transitioning to clean energy, with declining coal consumption and increasing adoption of renewables. While challenges remain in certain sectors, the shift away from fossil fuels is crucial to address climate change, improve air quality, and strengthen energy independence. This transition requires a combination of policies, innovations, and investments to ensure a sustainable future for the planet and humanity.

Fossil fuels are the largest driver of climate change
Fossil fuels—coal, oil, and natural gas—are the largest driver of climate change. When burned, fossil fuels release large amounts of carbon dioxide (CO2) and other greenhouse gases into the air. These gases, including nitrous oxide and fluorinated gases, trap heat in the Earth's atmosphere, causing global warming and climate change. The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming, with 89% of global CO2 emissions in 2018 coming from fossil fuels and industry.
Coal is the most polluting energy source among fossil fuels, producing the most CO2 and local air pollution per unit of energy. It is responsible for over 0.3 degrees Celsius of the 1-degree increase in global average temperatures. Oil releases a significant amount of carbon when burned, contributing approximately one-third of the world's total carbon emissions. Natural gas, while promoted as a cleaner alternative to coal and oil, is still a fossil fuel, accounting for one-fifth of global carbon emissions.
The burning of fossil fuels for electricity and heat production is the largest single source of global greenhouse gas emissions, accounting for 34% of 2019 emissions. Industry, including manufacturing and industrial processes, is another major contributor, with 24% of 2019 emissions primarily from fossil fuels burned on-site for energy. Transport is also a significant contributor, with road vehicles, ships, and planes contributing to the combustion of petroleum-based products and the increase in energy demand for transportation.
While the world is reducing its reliance on fossil fuels, with a decline in coal-powered generation and the rise of electric vehicles, there are still sectors that are not on track to break their dependence on fossil fuels. Aviation, shipping, and industry are notable examples, with ongoing carbon pollution and a lack of widespread alternatives to jet fuel or ship diesel. Additionally, industrial processes such as cement-making and plastic production are expected to fail to significantly cut carbon-intensive fuel use by 2050.
To mitigate climate change, a rapid transition away from fossil fuels is necessary. Low-carbon sources of energy, such as nuclear and renewables, must be prioritized to reduce global carbon emissions and limit global warming to safe levels. While progress has been made with record investments in clean energy and the development of electric vehicles, emissions reduction targets set by scientists to limit dangerous global heating are still a long way off.

Phasing out fossil fuels will strengthen energy independence
Fossil fuels, including coal, oil, and gas, have been the dominant energy source globally for centuries. However, they are the largest driver of global climate change and are linked to millions of premature deaths annually due to local air pollution. As a result, there is a growing movement to phase out fossil fuels and transition to renewable energy sources.
The transition to renewable energy sources can also create new economic opportunities and jobs in the construction of new power plants and the manufacturing of related equipment. For instance, Germany's investment in wind power has resulted in the development of new power plants and the growth of the wind power industry.
Additionally, phasing out fossil fuels can reduce energy costs for consumers. While some worry that transitioning to renewable energy sources will increase prices, others argue that it will lead to cost savings. For example, heat pumps and other electric heating systems are expected to outsell fossil fuel boilers globally, providing consumers with more energy-efficient and potentially cost-effective alternatives.
While progress has been made, more efforts are needed to achieve a complete phase-out of fossil fuels. Global fossil fuel use is projected to flatten or decline by mid-century, with coal and oil use decreasing and gas use rising. However, to meet the goals of the Paris Agreement and limit global warming to 1.5°C, the vast majority of fossil fuel reserves will need to remain untapped.
