AB This study aims to highlight the importance of accurately estimating methane emissions, one of the mostdangerous and important greenhouse gases in the context of climate change. By incorporating methaneemissions as a variable within the integrated assessment model DICE (Dynamic Integrated Climate-Economymodel), we investigate how these emissions influence temperature changes and subsequently impact economicpolicies, including climate economic policies, carbon pricing, and non-price factors. We use the existing DICE-2020 and DICE-2023 models as references for our analysis. In addition to industrial emissions that can bedetected through satellite observations, we address the challenge of estimating natural emissions from wetlandsand permafrost, which leak gradually and are difficult to detect. By considering these emissions, we account fortheir exogenous nature and their divergence from the current situation. Our study reveals that incorporatingmethane emissions into the DICE model has significant implications for global temperature outcomes andsubsequent policy changes. We find that by implementing existing methane reduction policies, which includescutting the level of methane emissions in half and increase the carbon price in 4 times to 500 USD per ton,it is possible to achieve the more ambitious goal of limiting the global temperature increase to 1.5 ◦C by2100 in an optimistic scenario instead of the common target of 2 ◦C. More pessimistic scenarios that donot imply big change in methane emissions, but the same numerical data for carbon price, still suggests thepossibility of keeping the global temperature below 2 ◦C.
