🇫🇷 France's Historic Contribution to Global Warming Since 1850

France's Historic Contribution to Global Warming Since 1850

Key Insights

Historic Warming Impact

France's historic emissions have contributed around 49,000 megatonnes of CO2‑equivalent to warming, about 1.3% of the global total. On a population‑weighted basis, this translates to roughly 6 tonnes per capita per year-rated high-reflecting both an early industrial build‑up and decades of subsequent reductions.

Fossil CO2 Dominates The Picture

About four‑fifths of the impact comes from fossil CO2. Emissions grew steadily up to the late 1930s, dipped briefly around the early 1940s, then surged during the post‑war era to the early 1970s, peaking at well over 500 megatonnes per year. A long decline followed, reaching just under 300 megatonnes by the 2020s. Coal once led but fell sharply from the mid‑1960s and again after the late 1980s. Oil climbed rapidly in the 1960s-early 1970s to roughly 350 megatonnes per year before easing. Gas rose from the late 1950s to the mid‑2000s, then edged down. Land use has been a small net sink overall, offsetting a few percent of the total, with values mostly negative since the late 1960s and more persistently so after the mid‑1980s.

Methane And Nitrous Oxide Trends

Methane accounts for roughly 13% of France's warming impact. Emissions were fairly stable around 110 megatonnes per year through the mid‑20th century and have declined to the low‑60s since the late 1960s; the warming impact from methane declined sharply in recent decades. Livestock makes up over half of methane, peaking around the mid‑1970s and then trending down, while fugitive emissions rose with early coal activity and have largely collapsed since the 1990s. Nitrous oxide contributes about 9%, climbing through the post‑war decades before easing from the early 1980s; agriculture drives over half of this source. Fluorinated gases grew after the 1950s but remain small at roughly 1.5% of the total.

Actionable Priorities

Given high per capita impact, France has a strong responsibility to lead. Priorities include sustaining and accelerating declines in fossil CO2 (especially oil and remaining coal and gas), continuing to reduce methane from livestock and fugitive sources, and lowering agricultural nitrous oxide. Progress at home, alongside support for other nations to avoid high‑emission pathways, would meaningfully cut future warming.

Background

Historic Per Capita Emissions

Historic per capita emissions are a crucial long-period (since 1850), population-weighted (accounting for changing population size) indicator. It shows the contribution of greenhouse gas emissions of a nation per capita per year to the current warming.


The rating scale is:

  • Extremely High: above 10 tonnes per capita per year
  • Very High: above 7.5 tonnes
  • High: above 5 tonnes
  • Moderate: above 2.5 tonnes
  • Low: above 0 tonnes
  • Negative Emissions: under 0

Historically, we don't expect any nation to reach negative emissions. Current warming, or warming targets, like 1.5 °C and 1.7 °C are all based on the fact that there have been human-induced greenhouse gas emissions and there will be some more. It is clear, however, that some nations have had incredibly high historic contributions per capita.

Total Historic Impact

This is the total amount of CO2, CH4, N2O, and F-Gases emissions of a nation from 1850 till 2023 (last available year in the data) expressed in megatonnes of CO2-equivalents. The gases have different atmospheric lifetimes (decay) and warming effects, for this reason we use the GWP100 (100 year time horizon method) to calculate the global warming potential of N2O and F-Gases to express in CO2-equivalents. For CH4, which is a short-term gas, we use the GWP* method to express the historic impact in CO2-equivalents.

Total Historic Share

This is a nation's total historic share of global emissions and its contribution to global warming. It is an indicator of historic responsibility. All nations share the responsibility to ensure that developing nations do not copy and repeat the behavior of nations with high historic greenhouse gas emissions, they should not buy into old unsustainable fossil-fuels-based technology, land-use, and infrastructure, rather foster a sustainable and cleaner development.

About the Data

The last available year in all the emission datasets is 2023. CO2 emissions data is from the Global Carbon Project. It contains national CO2 emissions from fossil sources and land-use change. Emissions from CH4, N2O and F-gases come from the PRIMAP-Hist dataset. It is a rich dataset that combines several published sources to create a historical emissions time series for various greenhouse gases. Population data are also from Global Carbon Project where available, however, for many nations it doesn't have historic population going back to 1850. Those historic gaps are filled with population data from Our World in Data.

The Key Insights paragraph was created using a large language model (LLM) in combination with our data, historic events, and a structured approach for best accuracy by separating the context generation from the interpretation and narrative.
