New Delhi: Though fossil fuel emissions are estimated to decrease marginally in 2026, India’s carbon emissions are set to rise by a significant 4.4%, according to the 2026 Global Carbon Budget, published by the Global Carbon Project on Tuesday (November 10) as a pre-print at the 31st Conference of Parties currently underway at Antalya, Türkiye.Per the study, the main reason for the overall global decline in carbon emissions is the Iran conflict that has effectively blocked the Strait of Hormuz, a crucial passage for oil from West Asia and into the rest of the world, and the resulting expansion of solar and wind power that this has triggered.The global carbon budgetA research team including the University of Exeter, the University of East Anglia (UEA), CICERO Centre for International Climate Research, the Ludwig-Maximilian-University Munich (LMU), the Alfred-Wegener-Institut and more than 90 other institutions around the world, have put together this year’s Global Carbon Budget.The budget is an annual inventory released by the project (which is a collaboration between Future Earth, a collective of scientists and the World Climate Research Programme, formed under the UN’s World Meteorological Organisation and sponsored by UNESCO) during all UN climate change summits.This year, the budget projects that fossil fuel emissions will release 38.2 billion tonnes of fossil carbon dioxide (CO2). With emissions from land-use change (such as deforestation) projected to increase slightly this year, total CO2 emissions are projected to be 43.3 billion tonnes in 2026, up from 42.8 billion tonnes last year.The remaining carbon budget (the amount of CO2 that can be emitted before warming reaches 1.5°C above pre-industrial levels) is now 150 billion tonnes. This means the world has less than four years of emissions to fill up the entire carbon budget at the current rate, to limit global warming to below 1.5 Degrees Celsius above pre-industrial levels.According to the study, the concentration of CO2 in the atmosphere is set to reach 427.7 ppm in 2026, 54% above pre-industrial levels.Decline in fossil carbon emissionsPer the study, emissions from oil are projected to decrease by 1.9%, likely a short-term response to the energy crises triggered by the Iran conflict worldwide.The study suggests that China’s emissions in 2026 are projected to decrease by 0.9%, following two years of low emissions growth. In addition to a strong decrease in oil emissions, coal emissions rose slightly (0.3%) and electricity generation from renewables continues to grow strongly. While China produces 32% of global fossil emissions, it is also the country most active in deploying clean technologies and increasing carbon sinks through reforestation.Also read: COP30: India’s Carbon Emissions Growing Slower But Global Carbon Budget Nearly ExhaustedHalf of the global emissions avoided due to renewable energy and electric vehicles are in China, which also has the largest carbon uptake through reforestation and afforestation (new forests).The USA’s emissions are projected to decrease by 1.3%, mainly due to a decrease in coal emissions (which spiked last year due to high natural gas prices and cold weather). European Union emissions are projected to decrease by 1.5%. Japan’s emissions are projected to decrease by 1%. Emissions for the rest of the world are projected to decrease by 0.7%.The largest component of the decline is in oil, likely driven by increased prices and global supply constraints. Emissions from international aviation and international shipping are also projected to decrease by 1%. Aviation’s decline is partly due to reduced activity in West Asia.India’s emissions to riseIndia’s emissions, however, are projected to increase by 4.4%, higher than the 3.5% average annual growth over the last decade.The report also assessed natural “sinks” (absorption of CO2 by land and ocean). It finds that the land sink returned to former levels after a severe weakening during the 2023-24 El Niño weather pattern. However, the powerful 2026 El Niño is expected to have a significant impact in the coming year.Global CO2 emissions from land-use change have decreased in the past decade but are projected to rise this year to 5.1 billion tonnes. This is driven by an increase in emissions from peat fires (almost entirely ignited by human activities) and forest degradation in Southeast Asia, associated with drier conditions linked to the onset of El Niño conditions.Total CO2 emissions – the sum of fossil and land-use change emissions – have grown more slowly in the past decade (0.3% per year), compared to the previous decade (1.7% per year).Emissions from permanent deforestation remain high at around 3.8 billion tonnes of CO2 per year over 2016-25. Permanent removals through reforestation and afforestation offset around half of the permanent deforestation emissions.Need more clean energyThe study noted that though global energy demand continues to rise, two thirds of the increase is being met by increased solar and wind power and electric vehicles. But clean energy growth is still not yet fast enough for a durable decline in global fossil CO2 emissions.“A decline in fossil CO2 emissions is encouraging, but a reduction driven partly by geopolitical shocks is not a sustainable climate solution,” said Professor Pierre Friedlingstein, director of the Global Carbon Budget Office at the University of Exeter, who led the study.“The long-term answer remains the rapid deployment of clean energy technologies. While renewables and electric vehicles are increasingly offsetting growth in energy demand, further acceleration is needed if global emissions are to peak and enter a sustained decline,” he said.Also read: Cabinet Approves India’s Third Climate Targets, Aims for 47% Emissions Cut by 2035A drop in emissions in one year is not a peak unless it is driven by structural change, commented Glen Peters, Research Professor at the CICERO Centre for International Climate Research, in a statement.“Accelerated deployment of solar, wind, batteries, and electric vehicles are pushing emissions down in dozens of countries, and slowing emissions growth in many more, but the changes are not sufficient to lock in a peak in global emissions,” he said.Uptake of carbon emissionsThe largest carbon uptake through reforestation and/or afforestation occurs in China, the EU27 and the USA, with combined removals 0.8 billion tonnes CO2 per year. Substantial uptake through these mitigation measures also occurs in other regions such as Brazil, Russia and Indonesia, but here it is outweighed by emissions from deforestation.Current levels of novel Carbon Dioxide Removal (excluding conventional means such as reforestation) currently offset only less than 30 minutes of annual fossil CO₂ emissions.“Clean technologies are making a real difference in reducing global emissions,” said Corinne Le Quéré, Royal Society Research Professor at UEA’s School of Environmental Sciences. “Solar and wind power and electric vehicles are expanding rapidly, led by China. Countries on every continent are decreasing their emissions while growing their economies. A further acceleration could turn the tide on global emissions within a few years.”
