The Global Infrastructure Emission Database (GID) is a unit-level dataset of CO₂– and air pollution-emitting infrastructure worldwide, developed and maintained by Tsinghua University, China since 2020. It is designed to provide open access to uniform, high-quality, and up-to-date data for scientific research, policy assessment, and climate and environmental management. Our team believes GID is thus a powerful tool to track global infrastructure changes for research on climate change and air pollution issues worldwide.

Development Goals >

Human activities generate large amount of greenhouse gases (GHGs) and air pollutant emissions, which are closely linked with climate change and environmental issues and have detrimental impacts on human wellbeing. In particular, power, industry, and transport infrastructure account for large shares of these anthropogenic emissions, making it important to accurately estimate the capacity and geo-locations of such infrastructure, to improve our understanding of emissions sources and mitigation opportunities.

GID allows for a deeper understanding of anthropogenic emissions from global infrastructure, including power, specific industries (iron and steel, cement, and petrochemicals) and transport sectors. The database provides emissions of both carbon dioxide (CO₂) and various air pollutants with continuous time series. The online products encompass detailed basic information of the infrastructure and its emissions at both regional and unit-/facility-levels, as well as different analysis of the data.

We welcome international scientific collaborations to develop the GID as an open-access and integrated emission platform, in order to offer high-quality infrastructure emission data products to the community.

Features >

• GID data aims to cover global major anthropogenic infrastructure including power, industry (cement, iron and steel and petrochemical, etc.), and transport sectors, and to provide multi-level basic infrastructure information and emissions estimates for carbon dioxide (CO₂) and various air pollutants (SO₂, NO_x, CO, VOCs, primary PM, black carbon (BC), and organic carbon (OC));
• The development of GID products is based on unit-/facility-level infrastructure information, and the plant-level information is provided online under the permission of original data sources.
• The database is built on the uniform methodology and will be maintained and updated continuously.
• The product includes multi-dimensional data analysis at region-, country-, plant-level.

Development History >

GID was launched in 2020 on the basis of the GPED dataset developed since 2017, and will be regularly updated to reflect changes in infrastructure.

• In February 2021, the GID v1.0 product was published online, including unit-level emission data of power plants (GPED), iron and steel industry (GISD), and cement industry (GCED). The GID v1.0 dataset provides CO₂ emissions and associated basic information of global infrastructure in 2019 at different aggregated levels (region-, country-, and plant-level).
