Global carbon dioxide emissions from fossil fuels and industry totaled 37.01 billion metric tons (GtCO₂) in 2023. Emissions are projected to have risen 1.08 percent in 2024 to reach a record high of 37.41 GtCO₂. Since 1990, global CO₂ emissions have increased by more than 60 percent. Who are the biggest emitters? The biggest contributor to global GHG emissions is China, followed by the United States. China wasn't always the world's biggest emitter, but rapid economic growth and industrialization in recent decades have seen emissions there soar. Since 1990, CO₂ emissions in China have increased by almost 450 percent. By comparison, U.S. CO₂ emissions have fallen by 6.1 percent. Nevertheless, the North American country remains the biggest carbon polluter in history. Global events cause emissions to drop The outbreak of COVID-19 caused global CO₂ emissions to plummet some 5.5 percent in 2020 as a result of lockdowns and other restrictions. However, this wasn't the only time in recent history when a major global event caused emissions reductions. For example, the global recession resulted in CO₂ levels to fall by almost two percent in 2009, while the recession in the early 1980s also had a notable impact on emissions. On a percentage basis, the largest annual reduction was at the end of the Second World War in 1945, when emissions decreased by 17 percent.

Introduction

Carbon Emission Statistics: Carbon emissions are a major cause of climate change. They mostly come from burning coal, oil, and gas. Cars, factories, power stations, and even homes release carbon into the air. Over time, the amount of carbon in the atmosphere has increased significantly. This leads to hotter weather, rising ocean levels, and stronger storms.

​In 2023, global carbon dioxide (CO₂) emissions from fossil fuels and industry reached approximately 37.01 billion metric tons, marking a continued upward trend in greenhouse gas emissions. China remained the largest contributor, accounting for over 31% of global CO₂ emissions. The United States and India followed, emitting significant portions of the total. The power sector was the leading source, responsible for 15 billion metric tons of CO₂ equivalent emissions. These escalating emissions have elevated atmospheric CO₂ concentrations to 419.3 parts per million, a 50% increase from pre-industrial levels.

The rise in greenhouse gas emissions contributes to global warming, resulting in increased temperatures, rising sea levels, and more frequent extreme weather events. Addressing these challenges necessitates comprehensive strategies to mitigate emissions across all sectors.

In 2023, China was the biggest carbon polluter in the world by far, having released 11.9 billion metric tons of carbon dioxide (GtCO₂). Although the U.S. was the second-biggest emitter, with 4.9 GtCO₂ in 2023, its CO₂ emissions have declined by 13 percent since 2010. By comparison, China’s CO₂ emissions have increased by more than 38 percent in the same period. Cumulative emissions Although China is currently the world's largest carbon polluter, the U.S. has released far more historical carbon dioxide emissions, at more than 400 GtCO₂ since 1750. The wide gap between the two countries is because China's emissions have mostly been produced in the past two decades. Combined, the U.S. and China account for roughly 40 percent of cumulative CO₂ emissions since the Industrial Revolution began. Sources of emissions One of the largest sources of global CO₂ emissions is the power sector, with electricity produced by coal-fired power plants a significant contributor. In China, emissions from coal-fired electricity generation have soared since the turn of the century, and reached 5.2 GtCO₂ in 2023.

Energy consumption in the United States produced 4.8 billion metric tons of carbon dioxide (GtCO₂) in 2024 - a decrease of 0.4 percent from the previous year. U.S. CO₂ emissions from energy consumption have fallen by approximately 20 percent since 2005. Sources of emissions in the U.S. The main source of CO₂ emissions in the U.S. is the transportation sector. For many years, the power sector was the country’s biggest contributor to CO₂ emissions, but the transition towards cleaner energy sources and a shift away from coal-fired power generation – the most carbon intensive fossil fuel – have slashed emissions from this sector. Meanwhile, transportation emissions have continued to rise, except for an unprecedented drop in 2020 due to the outbreak of COVID-19. U.S. transportation emissions The U.S. is the biggest contributor to global transportation emissions by far. The states with the largest transportation-related emissions in the U.S. are Texas and California, which combined account for almost one quarter of total U.S. transportation emissions.

OverviewThis emissions layer is part of the forest carbon flux model described in Harris et al. (2021). This paper introduces a geospatial monitoring framework for estimating global forest carbon fluxes which can assist a variety of actors and organizations with tracking greenhouse gas fluxes from forests and in decreasing emissions or increasing removals by forests. Forest carbon emissions represent the greenhouse gas emissions arising from stand-replacing forest disturbances that occurred in each modeled year (megagrams CO2e emissions/ha, between 2001 and 2024). Emissions include all relevant ecosystem carbon pools (aboveground biomass, belowground biomass, dead wood, litter, soil organic carbon) and greenhouse gases (CO2, CH4, N2O). Emissions estimates for each pixel are calculated following IPCC Guidelines for national greenhouse gas inventories where stand-replacing disturbance occurred, as mapped in the Global Forest Change annual tree cover loss data of Hansen et al. (2013). The carbon emitted from each pixel is based on carbon densities in 2000, with adjustment for carbon accumulated between 2000 and the year of disturbance.Emissions reflect a gross estimate, i.e., carbon removals from subsequent regrowth are not included. Instead, gross carbon removals resulting from subsequent regrowth after clearing are accounted for in the companion forest carbon removals layer. The fraction of carbon emitted from each pixel upon disturbance (emission factor) is affected by several factors, including the direct driver of disturbance, whether fire was observed in the year of or preceding the observed disturbance event, whether the disturbance occurred on peat, and more. All emissions are assumed to occur in the year of disturbance. Emissions can be assigned to a specific year using the Hansen tree cover loss data; separate rasters for emissions for each year are not available from GFW. All input layers were resampled to a common resolution of 0.00025 × 0.00025 degrees each to match Hansen et al. (2013).We have made several updates to the model since its original release. For documentation through the current version, please refer to this blog. For a more detailed description of the changes included through the 2023 tree cover loss launch (released spring 2024) and a comparison of the model's fluxes with those from the Global Carbon Budget and national greenhouse gas inventories, please refer to this article.Three variations of emissions rasters are available for download:megagrams CO2e emissions/ha in pixels with >30% tree cover density (TCD) in 2000 or tree cover gain: Used for visualizing (mapping) emissions according to the default GFW TCD threshold because it represents the density of emissions per hectare. You would use this if you want to only include emissions in pixels that are more conservatively defined as forest.megagrams CO2e emissions/pixel in pixels with >30% TCD in 2000 or tree cover gain: Used for calculating the emissions in an area of interest (AOI) according to the default GFW TCD threshold because the values of the pixels in the AOI can be summed to obtain the total emissions for that area. You would use this if you want to only include emissions in pixels that are more conservatively defined as forest.megagrams CO2e emissions/pixel in pixels with any amount of tree cover in 2000 or tree cover gain: Used for calculating the emissions in an area of interest (AOI) without any TCD threshold because the values of the pixels in the AOI can be summed to obtain the total emissions for that area. This would represent the total emissions from tree cover loss in the AOI without applying a TCD threshold. You would use this if you want to include emissions in pixels that have low (<30%) TCD in 2000.The values in the megagrams CO2e/pixel layers were calculated by adjusting the emissions per hectare by the size of each pixel, which varies by latitude. Tree cover density in 2000 is according to Hansen et al. (2013) and tree cover gain between 2000 to 2020 is according to Potapov et al.

See Harris et al. (2021) for further information on the forest definition used in the analysis.Although emissions in each pixel are associated with a specific year of disturbance, emissions over an area of interest reflect the total over the model period of 2001-2024. Thus, values must be divided by 24 to calculate average annual emissions.Emissions reflect stand-replacing disturbances as observed in Landsat satellite imagery and do not include emissions from unobserved forest degradation.Emissions reflect a gross estimate, i.e., carbon removals from any regrowth that occurs after disturbance are not included. Instead, gross carbon removals are accounted for in the companion forest carbon removals layer.Emissions data contain temporal inconsistencies. Improvements in the detection of tree cover loss due to the incorporation of new satellite data and methodology changes between 2011 and 2015 may result in higher estimates of emissions in recent years compared to earlier years.

The Asia-Pacific region produced 18.9 billion metric tons of carbon dioxide (GtCO₂) from energy use in 2023. China's CO₂ emissions are by far the highest in the Asia-Pacific region, at more than 10 GtCO₂ per year. The second most polluting region in 2023 was North America, where 5.9 GtCO₂ were generated, the majority of which came from the U.S. Global CO₂ emissions growth Global CO₂ emissions from energy consumption have more than doubled since 1970, and reached a record high in 2023. The rise in emissions is mainly due to rapidly growing economies and increasing energy demand in developing regions. This is especially the case in the Asia-Pacific region, where emissions have almost tripled since the turn of the century. The Middle East has also seen a dramatic rise in emissions, going from producing the lowest CO₂ emissions worldwide in 1965, to the fourth-highest as of 2023. Atmospheric carbon dioxide concentrations The increased burning of fossil fuels - as well as deforestation and other human activities - has seen atmospheric CO₂ concentrations surge in recent decades. In 2023, global atmospheric concentrations of CO₂ reached a record high of 421.08 parts per million, which is roughly 50 percent higher than before the industrial revolution.

The average American was responsible for emitting 13.8 metric tons of carbon dioxide (tCO₂) in 2023. U.S. per capita fossil CO₂ emissions have fallen by more than 30 percent since 1990. Global per capita emission comparisons Despite per capita emissions in the U.S. falling notably in recent decades, they remain roughly three times above global average per capita CO₂ emissions. In fact, the average American emits more CO₂ in one day than the average Somalian does throughout the entire year. Additionally, while China is now the world’s biggest emitter, the average Chinese citizen’s annual carbon footprint is roughly half the average American’s. Which U.S. state has the largest carbon footprint? Per capita energy-related CO₂ emissions in the U.S. vary greatly by state. Wyoming was the biggest CO₂ emitter per capita in 2022, with 97 tCO₂ per person. The least-populated state’s high per capita emissions are mainly due to its heavily polluting coal industry. In contrast, New Yorkers had the one of the smallest carbon footprints in 2022, at less than nine tCO₂ per person.

The Greening Government Strategy establishes climate and environmental commitments for the Government of Canada’s internal operations. The Government of Canada’s operations will be net-zero emissions by 2050 including: • Government owned and leased real property • Mobility: fleets, business travel and commuting • Procurement of goods and services • National safety and security (NSS) operations To implement net-zero in real property and fleet operations, the Government of Canada will reduce absolute Scope 1 and Scope 2 GHG emissions by 40% by 2025 and at least 90% below 2005 levels by 2050. On this emissions reduction pathway, the government will aspire to reduce emissions by an additional 10% each 5 years starting in 2025. The Government of Canada tracks its energy use and its GHG emissions across 29 departments and agencies. As of fiscal year 2023-24, we have reduced GHG emissions from federal facilities and conventional fleet (excluding NSS) operations by 42% from 2005 levels. The Government of Canada’s Scope 1 and 2 GHG emissions result from the energy used for its facilities and fleets: • facilities comprise office space, defence bases, laboratories, warehouses and other building types • fleets comprise on-road vehicles and off-road fleets, including cars, vans, trucks, boats, ships and planes. It consists of vehicles and equipment primarily used to transport people and cargo in the conduct of government business. Updated data for fiscal year 2023 to 2024 shows that GHG emissions continue a downward trend and remain below the pre-pandemic levels of 2019-2020. Operational improvements (e.g. portfolio rationalization, increased energy efficiency), clean electricity procurement and a warm winter in southern Ontario and Quebec contributed to a reduction of GHG emissions from the previous year (2022-2023). In addition, some year-to-year changes in GHG emissions may be due to data collection gaps, methodology or error correction refinements, while others may be the result of one-time or specific events or actions (such as natural disasters or operational disruptions). Additionally, variations in seasonal weather conditions (for example, the effect of heating or cooling days on building energy use) also influence annual GHG emissions. Data for some facilities have been excluded for operational reasons. Therefore, the results of calculations using this data may not align with other published results.
