Clean energy and carbon capture
The transition from fossil fuels to clean energy is well underway, with record investments in solar, wind, and electric vehicles. However, to meet the Paris Agreement's net-zero emissions targets by mid-century, we must rapidly phase down fossil fuel demand and supply. Carbon capture and storage (CCS) technologies are essential to achieving this goal. CCS involves capturing CO2 from power generation or industrial facilities, compressing it, and either using it in various applications or storing it in deep geological formations. Bioenergy with carbon capture and storage (BECCS) is a promising technique that removes CO2 from the atmosphere while generating energy. Governments are investing heavily in CCS, with over USD 20 billion available for projects, and capture capacity is expected to quadruple by 2030.
Clean energy sources like solar and wind power are crucial in reducing our reliance on fossil fuels. The International Energy Agency has called solar power the cheapest source of electricity in history. Electric vehicles are also driving down emissions, with global oil consumption for on-road vehicles projected to drop by 50% over the next three decades. These advancements show that we can break free from fossil fuels in many aspects of our lives, but challenges remain in sectors like aviation, shipping, and industry, which heavily rely on fossil fuels.
Carbon capture and storage technologies are vital to addressing emissions from industries like steel, iron, cement, and chemical production, which are inherent in our basic living but challenging to decarbonize. CCS can be retrofitted to existing power and industrial plants, enabling continued operation while reducing emissions. BECCS, in particular, offers the dual benefit of energy generation and carbon capture, making it a valuable tool in the transition to net-zero emissions. However, the development of infrastructure to transport and store captured CO2 needs to accelerate to match the required pace of decarbonization.
While CCS has the potential to revolutionize emissions reduction, it must be implemented alongside other strategies. Interconnected CCS systems are the most efficient way to store carbon dioxide, allowing for economies of scale. To facilitate the widespread adoption of CCS, governments must provide financial incentives, mandate emission caps, and develop technology-specific public policies that support research, network expansion, and cross-border collaboration. With these efforts, we can harness the potential of CCS to combat climate change and create a sustainable future.
In conclusion, clean energy sources and carbon capture technologies are crucial in reducing our dependence on fossil fuels and mitigating climate change. Record investments in renewables and EVs are driving down emissions, but we must also address carbon pollution in aviation, shipping, and industry. CCS and BECCS offer promising solutions for capturing and storing carbon dioxide, but they must be rapidly scaled up with the support of governments and stakeholders. By integrating clean energy and carbon capture into our energy systems, we can achieve the deep emissions reductions necessary to protect our planet for future generations.

The rise of electric vehicles
The world is witnessing a significant reduction in the use of fossil fuels, with clean energy sources gradually replacing fossil fuels. This transition is particularly evident in the transportation sector, where the rise of electric vehicles (EVs) is playing a pivotal role in decreasing our dependence on fossil fuels.
Electric vehicles, first introduced in the late 1800s, have experienced a surge in popularity in recent years. This trend is driven by several factors, including technological advancements, declining costs, and growing environmental concerns. Improvements in battery technology and the expansion of EV charging stations have made EVs more accessible and appealing to consumers.
The environmental benefits of EVs are significant. Traditional internal combustion engine (ICE) vehicles rely heavily on fossil fuels, contributing to air and noise pollution and releasing substantial greenhouse gas emissions. In contrast, EVs, including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), offer clean energy solutions. BEVs, in particular, produce zero tailpipe emissions, helping to mitigate environmental degradation and promote energy sustainability.
The shift towards EVs is also influenced by government incentives and policies. Governments worldwide are implementing stricter environmental regulations and offering tax benefits to encourage the adoption of EVs. These measures provide a clear framework for the transition to cleaner energy sources and signal the importance of EVs in future mobility. Commercial fleets, operated by organizations across sectors, are also contributing to this shift by embracing EVs and decarbonizing their operations.
Analysts project that the global electric vehicle charging infrastructure market will reach US$221.9 billion by 2030, reflecting the growing demand for EVs. This transition in the transportation sector is crucial in reducing global oil consumption and driving down emissions from cars and trucks, ultimately contributing to the decline in fossil fuel usage.

Fossil fuel consumption by country
Despite growing calls for a transition to renewable energy sources, fossil fuels remain the primary energy source globally. In 2017, 81% of the world's energy consumption was from fossil fuels, namely oil, coal, and natural gas. While there has been a decline in coal-powered generation, fossil fuel consumption is expected to remain high due to rising energy demands.
The United States is the largest consumer of oil, with over 19.1 million barrels consumed per day in 2022, and 32.2 trillion cubic feet of natural gas consumption. The US is also not on track to reduce its fossil fuel consumption in the next 30 years, according to a Rhodium analysis.
Russia is another major player in the oil market, producing 11.28% of the world's oil in 2021, and consuming 3.67 million barrels daily, accounting for 4% of global consumption. Russia is also one of the largest consumers of natural gas, with 408 billion cubic meters consumed in 2022.
Canada, with its heavy reliance on oil, coal, and gas, consumed 98 million metric tons of oil in 2022. Despite efforts to transition to renewable energy, Canada's fossil fuel consumption remains notable.
Other countries with significant fossil fuel consumption include Japan, which ranked fifth in global fossil fuel consumption in 2022, and Korea, which was the seventh-largest energy consumer in 2022, importing 960 million barrels of crude oil and 126 million tons of coal in 2021.
While the transition to renewable energy is gaining momentum, with record investments in clean energy and the growth of electric vehicles, countries with high fossil fuel consumption rates must make concerted efforts to reduce their carbon footprint and contribute to a more sustainable future.

Fossil fuel production metrics
Fossil fuels, including petroleum, natural gas, and coal, have been the primary energy source for production and consumption in the United States. In 2019, 80% of domestic energy production and consumption originated from fossil fuels. The share of total energy production from fossil fuels in the US peaked at 93% in 1966. Since 2008, there has been an increase in the production of crude oil, dry natural gas, and natural gas plant liquids (NGPL) in the US, amounting to 15, 14, and 4 quadrillion British thermal units (quads), respectively.
On a global level, fossil fuels account for a smaller share of electricity production than the energy system as a whole. Oil contributes a small share of electricity production, while coal and gas are the predominant sources. Gas has become the second-largest source of electricity production worldwide, and its use is increasing as countries transition away from coal. Despite the shift towards gas, the ultimate goal is to adopt low-carbon energy sources such as renewables and nuclear power.
While global fossil fuel consumption is projected to flatten or decline by mid-century, it will likely increase again due to rising energy demands. To achieve net-zero emissions by 2050 as outlined in the Paris Agreement, a rapid phase-down of fossil fuel demand and supply is necessary. This involves reducing coal use by 15-30% by 2030, gas by 15-20%, and oil by 5-15%. However, some emissions will need to be offset by carbon capture and removal technologies, which have limitations in terms of scaling up by 2050.
Despite progress in reducing fossil fuel consumption, aviation, shipping, and industry remain significant contributors to carbon pollution. The absence of widespread alternatives to jet fuel and ship diesel hinders the transition to cleaner energy sources in these sectors. Additionally, certain industrial processes, such as cement-making and plastic production, will continue to rely on carbon-intensive fuels.

The future of aviation and shipping
Aviation and shipping are two sectors that are highly dependent on fossil fuels. However, with the growing awareness of the impact of fossil fuels on the environment, the future of these industries is expected to undergo significant changes.
Aviation
The aviation industry has a significant and rapidly growing impact on the climate. Aviation accounted for 2.5% of global energy-related CO2 emissions in 2023, and emissions are expected to surpass their 2019 pre-pandemic levels by 2025. The industry faces challenges in greening its capital due to its reliance on the high energy density provided by fossil fuels. However, there has been notable progress, including the adoption of policies and regulations to promote sustainable aviation fuels (SAFs). For example, in 2023, the European Union adopted ReFuelEU Aviation, which mandates minimum SAF blend-in shares through 2050. Brazil also adopted the Fuel of the Future law in 2024, which aims to reduce GHG emissions from domestic flights.
To align with the Net Zero Emissions by 2050 Scenario, stakeholders in the aviation industry must increase the use of low-carbon fuels, improve aircraft and engine design, and implement demand restraint solutions. Technology innovation is crucial, including the development of low-emission fuels and improvements in aircraft and engine efficiency. Additionally, demand management strategies, such as optimizing operations and implementing fiscal and regulatory policies, will play a vital role in curbing emissions growth.
Shipping
The shipping industry also contributes significantly to global carbon emissions, accounting for about 3% of global greenhouse gas emissions. The massive ships that transport goods by sea burn heavy fuel oil, emitting large quantities of particulates and greenhouse gases. As global commerce continues to expand, the need for a transition to low-carbon alternatives in the shipping industry becomes increasingly urgent.
The path to decarbonizing maritime transport is not entirely clear, but there is a growing recognition of the urgency for change. Large multinational organizations have set ambitious targets, aiming to cut emissions from shipping by 50% in the coming years. The shipping industry is exploring alternative fuels, such as hydrogen, with a focus on renewable production methods to reduce their environmental impact.
