IGES List of Grid Emission Factors

The List of Grid Emission Factors aims to provide information to be utilized for research and analysis regarding emissions from electricity generation. A "grid emission factor" refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the...

IGES GHG Emissions Database

IGES's GHG emissions database aims to compile the latest information on GHG and CO2 emissions, as reported annually by UNFCCC Annex I countries. The data covers the period from from 1990 up to two years before the submission date of the reports. This database also provides information on target compliance, in order to compare historical emission...

Global waste sector dataset (1990–2050): scenario-based projections of generation, emissions, and socioeconomic drivers

In Frontiers in Environmental Science

Strategy planning for global climate goals requires structured, multisectoral data linking environmental pressures with socioeconomic drivers across time and geography. However, internationally harmonized, machine-actionable datasets integrating waste generation, waste-related greenhouse gas (GHG) emissions, and socioeconomic indicators remain...

Land remains a blind spot in tracking progress under the Paris Agreement due to lack of data comparability

In Communications Earth & Environment

Land carbon fluxes are key to the Paris Agreement. However, data comparability issues persist between countries’ land greenhouse gas inventories and mitigation targets, and what land models (bookkeeping and integrated assessments) provide as Paris-aligned benchmarks for land. As a result, the Global Stocktake, aiming to track collective mitigation...

Improving land-use emission estimates under the Paris Agreement

In Nature Sustainability

Climate science and national emissions reporting communities have historically used different definitions and methods for anthropogenic land-based carbon removals. As the mitigation agenda accelerates, reconciling these differences for comparability and moving towards integration is crucial for enhancing confidence in land-use emission estimates.
