Overview

Global coal demand growth is slowing year over year. However, annual production remains record high, and the scale of existing and planned projects still threatens climate targets.

Coal mining remains a foundational component of global industry and energy production, yet its continued expansion creates significant challenges for a sustainable future. Understanding the scale of this infrastructure and phaseout considerations is critical as the industry evolves. While the coal power sector is experiencing a steady wave of retirements, the coal mining sector lags behind in its phaseout plans, due to an expanding metallurgical coal market, high demand and high energy prices as a result of the wars in Ukraine and Iran, and a growing number of countries seeking energy independence by increasingly leveraging their domestic coal resources. 

GEM’s latest coal mine research identifies 837 coal mine proposals totaling 2,533 million tonnes per annum (Mtpa) under development — a nearly 12% increase from 2024. While new mine capacity openings continue to decline, having dropped by more than 50% since 2024, the global pipeline remains massive. With 700 Mtpa already under construction, these projects lock in decades of production and increase the risk of stranded assets in a rapidly evolving market.

Global development is heavily concentrated in China, India, Australia, Russia, and South Africa, which represent over 90% of all proposed capacity. China alone accounts for 1,329 Mtpa — more than the rest of the world combined. Thermal coal for power generation still dominates global expansion plans, accounting for around 70% of proposed capacity, but the development of metallurgical coal for steelmaking is increasingly important, as deeper underground operations increase  its methane intensity.

The climate, environmental, and human costs of this infrastructure are central to a clean and just energy transition. Beyond carbon dioxide from coal combustion, coal mining releases immense volumes of methane, often surpassing the gas sector’s footprint, despite receiving far less scrutiny. Proposed mines alone could emit 16.8 million tonnes of methane annually.
