Guatemala's Historic Contribution to Global Warming Since 1850
Key Insights
High Per Capita Emissions
Guatemala's historic greenhouse gas emissions have resulted in a high per capita impact of 7.17 tonnes per year. This places the country in the "high" category on the per capita emissions scale. The significant contribution to this impact stems from various historical events and developments. Notably, the Liberal Reform in 1871 led to extensive land-use changes as coffee plantations expanded, contributing to increased CO₂ emissions. The expansion of agriculture, particularly during the post-1996 Peace Accords period, further amplified emissions due to land conversion and increased fertilizer use, which elevated N₂O emissions.
Land-Use Changes and Agriculture
Land-use changes have been a major driver of Guatemala's historic emissions. The coffee boom initiated in the late 19th century and the agro-industrial expansion in the 21st century, particularly in palm oil and sugarcane, have significantly contributed to CO₂ emissions. These activities often involved deforestation and land conversion, which are key sources of greenhouse gases. Additionally, the intensification of agriculture has led to increased N₂O emissions, primarily from fertilizer application. The combination of these factors has played a crucial role in shaping Guatemala's warming impact.
Global Share and Responsibility
Despite its high per capita emissions, Guatemala's total historic share of global emissions is relatively modest at 0.16%. This reflects the country's smaller overall contribution to global warming compared to larger industrialized nations. However, Guatemala's experience underscores the importance of sustainable development practices. As the country continues to grow, it faces the challenge of balancing economic development with environmental responsibility, ensuring that future growth does not replicate the unsustainable practices of the past. This highlights the shared global responsibility to foster cleaner and more sustainable development pathways.
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.
Wikipedia: Global Warming PotentialTotal 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.
