Review on Urban GHG Inventory in China

Abstract

Abstract:With the rapid urbanization progress of China, a study on an urban GHG inventory is of great significance. However, related studies in China are still in the exploratory stage. This paper firstly introduces three major urban GHG inventory accounting methods and related issues with regard to Chinese cities, and then reviews the published studies of urban GHG inventories in China in the past few years. Methodology frameworks, gas types, emission scopes, geographical boundaries are examined and compared. With great distinctions in the accounting methods and contents, there is no direct comparability between the research results. However, the following characteristics can still be found: the GHG emissions per capita and GHG emissions per unit of GDP are higher than the world average level, and the total GHG emissions maintains an increasing trend, although the GHG emissions per unit of GDP keeps declining. Currently, researches on the urban GHG inventory in China are mainly based on the non-urban-level IPCC Guidelines and Provincial-level guidelines. The release of urban-level GHG inventory estimation guidelines in China is expected to provide unified standards for related studies in the future.

City-level climate change mitigation in China

“…Furthermore, in the "Global Protocol for Community-Scale Greenhouse Gas Emission Inventories" and "International Local Government GHG Emissions Analysis Protocol", WRI et al (37) and Local Governments for Sustainability (ICLEI) (38) provided a bottom-up approach for higher-precision city-level emission accounting. The ISO 14064 and 37120 series of standards also provided guidelines for emission accounts at the enterprise level (39). 43) used nighttime light imagery to estimate city CO 2 emissions.…”

The impact of economic policy uncertainty on carbon emissions: evaluating the role of foreign capital investment and renewable energy in East Asian economies

“…Chongqing, Incheon, Tianjin, and Shanghai were the top four cities with the highest carbon intensity. Moreover, some research have focused on the updating and establishment of CO 2 emission inventories (F. Yang et al, 2016 ), i.e., Japan prefectural emission accounts (Long et al, 2020 ), the China CO 2 emission accounts (Shan et al, 2018 ), and GHG emissions from megacities in South Korea (Marcotullio et al, 2012 ).…”

The Indonesian Government’s Role in Setting Renewable Energy Targets to Reduce GHG Emissions from the Electrical Energy Sector

“…Human activities, especially those that produce greenhouse gases (GHG), may pose a danger to the world's environment since elevated levels of GHG can lead to climate change. Carbon dioxide gas is the primary type of GHG emitted into the atmosphere (Choi et al, 2022), and GHGs are primarily to blame for the rise in average global temperature, which increased by 0.85 degrees Celsius between 1880 and 2012, according to the Intergovernmental Panel on Climate Change's Fifth Assessment Report (AR5) (Yang et al, 2016).…”
