The Ministry of Land, Infrastructure, and Transport (Minister Won Hee-ryong) decided to build a 'carbon space map' to realize comprehensive carbon neutrality in urban and regional spatial units, and on September 9 at 21:2 pm, the MOLIT Urban Policy Office presided over As a result, a policy meeting with city and environmental experts will be held to discuss ways to build and utilize carbon space maps.

The carbon spatial map visualizes and maps carbon emission and absorption information on the basis of spatial units of cities and regions (lattice, administrative district units, etc.)

This was started to prepare a data base for carbon emission and absorption in the land and urban areas to create a carbon-neutral space in the 「2050 Land, Transport Carbon Neutral Roadmap (‘21.12)」 22.3)”, the Minister of Land, Infrastructure, and Transport prepared a basis to prepare a map that reflects information such as greenhouse gas emissions and absorption in regional and spatial units.

Overseas countries such as the US, UK, and Japan have produced carbon spatial maps since the early 2000s and have been actively using them to establish spatial plans. (CREST: CO2 Reduction Effect Simulation Tool) has been developed and utilized.

Accordingly, MOLIT believes that it is difficult to accurately measure or manage and improve carbon emissions at the regional and city level with the existing information on carbon emissions by emission sources such as energy, industry, transportation, and buildings. It is the first time in Korea to build a carbon spatial map that can accurately represent the amount of carbon emission and absorption in a spatial unit of a dimension.

The Ministry of Land, Infrastructure, and Transport is expected to promote a research service* that establishes a carbon spatial map standard model and prepares policy utilization plans within this year, and expects to be able to provide a carbon spatial map service in the first half of next year.

First, we propose a data model of a carbon spatial map by constructing carbon emission data through energy information in the building and transportation sector and calculating carbon absorption through spatial information data for each land use such as parks, green spaces, and amusement parks in the city.

By linking existing information such as urban planning status information from the Land Use Information Integration Platform (KLIP) and population and traffic information for each space in SGIS, the carbon spatial map regularly shows land use status, traffic volume changes, population changes, etc. will reflect

At the same time, to increase the accuracy and usability of the carbon space map, we plan to promote a research and development project (R&D) to advance the carbon space map.

The scope of collection and utilization of carbon emission information is expanded from the point (building) unit to the line (road, railway) and face (settlement, green area) unit information, and it is possible to simulate changes in carbon emissions according to changes in urban spatial structure. to develop skills.

In the future, the carbon space map is expected to be used by the government to identify the level of carbon neutrality by city and to select and support carbon neutral cities in accordance with the Carbon Neutrality Framework Act.

In particular, each city sets effective greenhouse gas reduction targets based on the carbon spatial map and reflects carbon-neutral city planning elements in spatial structure, transportation system, and parks and green areas ('21.December, revised urban master plan establishment guidelines). It is planned to be actively used to create a neutral city.

In addition, when a carbon spatial map is established, a sophisticated carbon-neutral city management system that intensively manages areas with high carbon emissions can be prepared.

The Ministry of Land, Infrastructure, and Transport Urban Policy Officer Gil Byung-woo emphasized, “The carbon spatial map is significant in breaking away from the limit of access by sector centered on carbon emission sources and enabling an integrated approach centered on spatial units such as regions and cities.” He said, “Based on the carbon spatial map, we will accelerate the achievement of carbon neutrality across the country by establishing a carbon-neutral urban plan that reflects regional characteristics.”
