Cement production
- Data: https://www.usgs.gov/media/files/cement-historical-statistics-data-series-140
- Conversion from cement production to concrete production: factor 6.75 (according to Syvitski et al. (2020), https://www.nature.com/articles/s43247-020-00029-y#Sec8 )
CO₂ emissions from cement production
- Data: https://globalcarbonatlas.org/budgets/carbon-budget (except for 1930)
- For 1930: Huang et al. (2023): Global carbon uptake of cement carbonation accounts 1930–2021
Note: The CO₂ emission data are not corrected, although concrete reabsorbs CO₂ over its lifetime. These data are used because all other CO₂ emission sources also have portions reabsorbed through, among other processes, rock weathering.

Global energy consumption (renewable and fossil)
Conversion – Geothermal energy
Note: In the exhibition, geothermal energy is classified as renewable, unlike on ourworldindata.org. Thus, geothermal consumption (see iea.org) is subtracted from “Other” (ourworldindata.org) and added to “Renewables” (ourworldindata.org).
Note Data: The drop in global energy consumption in 2020 can be attributed to the COVID-19 pandemic.
Editorial deadline: May 31, 2025 – data updated annually.
Global annual CO₂ emissions by sector
Note: Illustrated are five major CO₂-emitting sectors powered by fossil fuels: 1. Energy production, 2. Industrial processes, 3. Transport, 4. Buildings, 5. Oil production
Note Data: The decline in CO₂ emissions in 2020 can be attributed to the COVID-19 pandemic.
Redaktionsschluss: May 31, 2025 – data updated annually.
Global CO₂ emissions from fossil fuels (oil, gas, coal)
- Data: https://globalcarbonatlas.org/
- Unit: per year
Note: Natural gas includes “gas + gas flaring,” meaning flaring data are added to natural gas data.
Note Data: The decline in global fossil fuel CO₂ emissions in 2020 can be attributed to the COVID-19 pandemic.
Editorial deadline: May 31, 2025 – data updated annually.
CO₂-equivalent total emissions
Temperature
CO2 Sinks
- Data: IPCC AR6 (2022) https://www.ipcc.ch/report/ar6/syr/
Projection
- IPCC AR6 (2021), Working Group III – Mitigation of Climate Change
- Global Carbon Project: https://www.globalcarbonproject.org
- Scenario data from IAMs (e.g., IMAGE, REMIND, MESSAGE-GLOBIOM via CMIP6)
- Selected scenario: SSP1-2.6
Note Scenario: SSP1-2.6 is a “climate policy scenario” in which greenhouse gas emissions drop sharply by 2050 and approach zero by 2100. This allows the global temperature target of <2°C to be met with high probability.
Wieso wurde dieses Szenario ausgewählt?
Why was this scenario chosen?
- Scientifically sound, not watered down
“The infographic aligns with the Paris Climate Agreement, which aims to limit warming to well below 2°C and preferably 1.5°C.
Our depiction is based on the IPCC SSP1-2.6 scenario, which represents this target range scientifically. We show a realistic pathway within recognized climate models.” - Comprehensible, to enable action
“Our goal is to present complex scientific relationships in a way that is understandable and motivating.
Showing only the strictest 1.5°C path often leads to paralysis – we want to convey that determined action can still have a decisive impact.” - Hope as part of responsibility
“We do not trivialize anything – we show that climate protection is still possible.
Hope is not sugarcoating, but a tool to move people rather than paralyze them.
This text aims to show: the situation is serious, but we still have room for action.”
Note Data: The decline in total CO₂ emissions in 2020 can be attributed to the COVID-19 pandemic.
