As the fourth largest CO2 emitter, Russia's constituent entities collectively contribute with vast territory and regional heterogeneity. Existing studies only present production‐based inventories; state‐level consumption‐based emissions patterns and driving forces remain rare. Here, we built the Russia state‐level Multi‐regional input‐output table to ascertain heterogeneity in consumption‐based emissions and track carbon flows in the inter‐state. We found that 60% of consumption‐based emissions coming from affluent areas (top 20% of the GRP), including Moscow (139.1 Mt) and St. Petersburg (50.5 Mt). Energy‐intensive regions also had huge consumption‐based emissions (31.6 Mt in Khanty‐Mansi Autonomous Okrug and 29.4 Mt in Republic of Tatarstan). Household consumption emissions accounted for 41%–73% of consumption‐based emissions in the 83 regions, except for Tula and Lipetsk, where fixed capital formation dominated. In addition, the major contributor of embodied emissions in households were power and services sectors, which contributed about 8%–61% (0.03 Mt–12.7 Mt) and 12%–40% (0.1 Mt–20.1 Mt). In Russia's low carbon transition, policymakers should not only focus on a local mitigation policy in developed states (such as Moscow and St. Petersburg), but on key sectors to curb the consumption. Regions with high carbon intensity should switch to renewable energy and implement cleaner production techniques in high‐emission industries. Plain Language Summary: Russia, as the world's fourth largest CO2 emitter, urgently needs to identify carbon emissions by region and by sector in order to formulate targeted mitigation policies. Therefore, we built the first Russian Multi‐regional input‐output table to analyze the consumption‐based carbon emissions of 59 industries in 85 regions. We also tracked the drivers of emissions and the imbodied emissions transfer pathways in each region. Results show that the majority of Russian emissions come from only a few economically developed regions (Moscow and St. Petersburg) and energy‐intensive regions (Khanty‐Mansi Autonomous Okrug and Republic of Tatarstan). Excluding Tula and Lipetsk, household final consumption is the main driver of consumption‐based emissions in the remaining 83 regions. We suggest that the impact of different types of regions and key sectors on Russia's overall carbon footprint should be the main focus when tailoring strategies to achieve Russian emissions reductions on a sub‐national scale. Key Points: 60.3% of Russia's consumption‐based emissions come from affluent regions (top 20% of GRP) such as Moscow and St. PetersburgApart from Tula and Lipetsk, household final consumption (40.6%–72.9%) is the main driver of emissions in the remaining 83 regionsPower sector (8.1%–60.6%) and basic services sector (12.1%–40.4%) are the main contributors to household consumption emissions by region [ABSTRACT FROM AUTHOR]
