{{SignalTerm|type=DS|id=DS-00849|label=Anthropogenic greenhouse gas emissions (AR5 100-year CO2e)}} Anthropogenic greenhouse gas emissions quantified as AR5 100-year CO2 equivalent represent the total annual emissions of greenhouse gases from human activities, expressed in terms of their global warming potential over a 100-year time horizon as defined by the Intergovernmental Panel on Climate Change ([https://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change IPCC]) Fifth Assessment Report (AR5). These emissions include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and other trace gases, aggregated into a single metric that facilitates comparison and assessment of their climate impact. This measure is critical for understanding the human contribution to climate change and supports international efforts to track progress toward emission reduction targets.

The data underlying this signal are derived from the Emissions Database for Global Atmospheric Research (EDGAR), which compiles annual country-level totals of greenhouse gas emissions. The AR5 100-year CO2e metric reflects the integrated warming effect of different gases over a century, providing a standardized basis for environmental monitoring and policy evaluation.

Within the broader context of global environmental monitoring, anthropogenic greenhouse gas emissions serve as a key indicator of human-induced climate forcing. Their quantification enables assessment of trends, identification of major emission sources, and evaluation of mitigation strategies across sectors and regions.

== Geographic / System Context ==
This signal is not confined to a specific geographic region but encompasses global anthropogenic emissions aggregated at national and sub-national scales. The emissions data reflect activities across diverse environmental and economic systems worldwide, including energy production, industrial processes, agriculture, and waste management. The geographic scope thus spans all countries and territories, capturing the spatial distribution of emissions sources as documented in the EDGAR database. This global perspective is essential for understanding the cumulative impact of human activities on the Earth's climate system.

== Monitoring and Measurement ==
Anthropogenic greenhouse gas emissions are monitored through comprehensive inventories compiled by scientific institutions using a combination of national reports, statistical data, and emission factors. The EDGAR database integrates these inputs with scientific methodologies to estimate annual emissions by country and sector. Measurement approaches include bottom-up accounting based on activity data and emission factors, as well as top-down atmospheric observations and inverse modeling techniques used by research agencies such as the European Commission and international collaborators. The AR5 100-year CO2e metric applies global warming potential values from the IPCC Fifth Assessment Report to convert different greenhouse gases into a common unit, facilitating consistent reporting and comparison.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.

== Signal Definition ==
The signal represents the annual total anthropogenic greenhouse gas emissions expressed in AR5 100-year CO2 equivalent units. It aggregates emissions of carbon dioxide, methane, nitrous oxide, and other greenhouse gases weighted by their respective global warming potentials over a 100-year time horizon as established by the IPCC AR5. The measurement is reported at the country level and reflects the sum of emissions from all human-related sources within national boundaries for a given year.

== Boundary Conditions ==
Boundary inclusions encompass all anthropogenic sources of greenhouse gases accounted for in the EDGAR inventory, including fossil fuel combustion, industrial processes, agriculture, land-use change, and waste management within national territories. Boundary exclusions include natural greenhouse gas fluxes such as those from wetlands, wildfires, and volcanic activity, as well as emissions from international aviation and shipping unless specifically allocated to countries. The signal excludes biogenic CO2 fluxes from land-use change that are not considered anthropogenic under the EDGAR methodology.

== Aggregation Semantics ==
Geographically, emissions are aggregated at national and sub-national scales based on administrative boundaries as defined in the EDGAR dataset. Temporal aggregation is annual, reflecting total emissions within a calendar year. Cross-signal aggregation involves combining multiple greenhouse gases into a single CO2 equivalent value using IPCC AR5 global warming potentials, enabling integrated assessment of climate forcing. This aggregation approach supports comparative analysis across countries and sectors and facilitates temporal trend evaluation.

== Observational Status ==
Current monitoring of anthropogenic greenhouse gas emissions is supported by the EDGAR v8.0 dataset, which provides updated and spatially detailed emission inventories. Data coverage is comprehensive for recent decades, with ongoing improvements in methodology and source data. Future SIGNAL releases may incorporate finer temporal resolution, expanded sectoral detail, and integration with atmospheric measurements for enhanced validation. Continued development aims to refine uncertainty quantification and support dynamic environmental assessment frameworks.
