Again, these figures are only useful as a static measure; they will continue to vary with time as our capacity to economically source and extract fossil fuels changes, and our levels of consumption rise or fall. However, whilst depleting reserves could become a pressing issue years from now, there is another important limit to fossil fuel production: climate change.
Carbon dioxide emissions remain trapped in the atmosphere for long periods of time, building up an atmospheric stock that leads temperatures to rise. To keep average global temperature increase below two degrees celsius as has been agreed in the UN Paris Agreement , we can thus calculate the cumulative amount of carbon dioxide we can emit while maintaining a probability of remaining below this target temperature. In the latest Intergovernmental Panel on Climate Change IPCC report, the budget for having a 50 percent chance of keeping average warming below two degrees celsius was estimated to be approximately billion tonnes of carbon as shown in the chart.
Both natural gas and oil production have surged in the U. By combining fracking—or hydraulic fracturing—with horizontal drilling and other innovations, the fossil-fuel industry has managed to extract resources that were previously too costly to reach. As a result, natural gas has surpassed coal to become the top fuel for U. Natural gas is cleaner than coal and oil in terms of emissions, but nonetheless accounts for a fifth of the world's total, not counting the so-called fugitive emissions that escape from the industry, which can be significant.
Undersea methane hydrates, for example, where gas is trapped in frozen water, are being eyed as a potential gas resource. Governments around the world are now engaged in efforts to ramp down greenhouse gas emissions from fossil fuels to prevent the worst effects of climate change. At the international level, countries have committed to emissions reduction targets as part of the Paris Agreement , while other entities—including cities, states, and businesses—have made their own commitments.
These efforts generally focus on replacing fossil fuels with renewable energy sources, increasing energy efficiency, and electrifying sectors such as transportation and buildings. However, many sources of carbon emissions, such as existing power plants that run on natural gas and coal, are already locked in. Considering the world's continuing dependence on fossil fuels, many argue that in addition to efforts aimed at replacing them, we also need to suck carbon from the air with technologies such as carbon capture, in which emissions are diverted to underground storage or recycled before they reach the atmosphere.
A handful of commercial-scale projects around the world already capture carbon dioxide from the smokestacks of fossil fuel-fired plants, and while its high costs have prevented wider adoption , advocates hope advances in the technology will eventually make it more affordable.

Major types of fossil fuels There are several main groups of fossil fuels, including: Coal: Black or brown chunks of sedimentary rock that range from crumbly to relatively hard, coal began to form during the Carboniferous period about to million years ago, when algae and debris from vegetation in swamp forests settled deeper and deeper under layers of mud.

Natural gas and renewables, including hydropower, are also expected to claim between 28 and 29 percent of total global power generation by , with the remainder coming from existing and new nuclear plants.
In one of the first high-level analyses of how U. EPA's Clean Power Plan would further shave coal consumption by roughly 1 percent after while driving a comparable increase in renewable energy deployment. Among the world's three largest coal users—the United States, China and India—only India is projected to see an overall increase in coal consumption by China is expected to begin reducing its use of coal after , while the United States is already seeing a downward trajectory in coal use, one that could grow steeper if the Clean Power Plan is upheld in court.
While U. In fact, by , nearly two-thirds of all of the world's energy use will be in developing countries outside the member Organisation for Economic Co-operation and Development. Among non-OECD members, Asian countries like China, India and Indonesia will account for 55 percent of all new energy use through , the analysis found. Increasing oil and liquid fuels consumption for industry and transportation will be particularly strong in countries like China and India, Sieminski said, where rising incomes and a proliferation of privately owned cars and trucks has led to significant increases in vehicles miles traveled VMT.
But critics like David Turnbull of the climate-focused nonprofit group Oil Change International said EIA should have given stronger consideration to shifting national and international climate policies, especially over the last several years.
