Abstract

According to climate data from the European Centre for Medium-Range Weather Forecasts, 2024 was recorded as the warmest year on record globally. For the second consecutive year—following 2023—the global temperature record was broken, with the summer of 2024 also reported as the hottest summer in history. In Iran, the annual positive temperature anomaly reached 2.084°C in 2024, and the country experienced its hottest August since records began in 1940. Based on projections from the IPCC's climate scenarios, temperature records are expected to be surpassed repeatedly in the coming decades, accompanied by increasingly frequent positive anomalies. These extreme heat events pose significant environmental challenges, underscoring the urgent need for effective greenhouse gas mitigation strategies. One such approach is carbon emissions trading—a market-based mechanism for reducing pollution through participation. This system enables countries to benefit from project activities that generate emission reduction certificates, which can be used to fulfill national or international greenhouse gas reduction commitments.
