Methane: The Silent Villain of the Climate Crisis

​Although carbon dioxide (CO2) stands as the most recognized villain in the climate change crisis, methane (CH4) is a formidable competitor. This powerful greenhouse gas, although commonly overlooked, has the ability to trap significantly more heat than CO2 molecules. O’Neill (2023) noted that “because of its chemical composition, methane has a much higher global-warming potential than carbon dioxide does—up to 80 times as much—and is responsible for about a third of current global warming”. However, unlike CO2, methane has a relatively short lifespan of approximately 20 years or less. Thus, it is greatly responsible for near-term global warming.
 
Methane is introduced into the atmosphere from both natural sources and human activities. While natural sources such as wetlands contribute to 40% of methane emissions, human activities, such as agriculture, fossil fuels and landfills, contribute substantially, recording 60% of global methane emissions (NASA, 2024). The concentration of methane in the atmosphere has continued to steadily increase from the 1900s as seen below.

Consequently, the reduction of methane emissions should be a primary focus in climate change discussions, as it can be utilized as an effective short-term response strategy. A notable effort in the reduction of methane emissions is the methane fee initiated by President Biden for oil and gas producers in the United States. According to Phillis and Daly (2025) “oil and gas producers are among the biggest U.S. methane emitters and controlling it is critical to address climate change”. As such, the policy, which formed part of the 2022 Inflation Act, aimed to promote the adoption of more environmentally friendly practices in the industry that reduced emissions and increased the efficiency of operations. Phillis and Daly also highlighted that “the fee was expected to reduce 1.2 million metric tons of methane emissions by 2035 — that’s about the same as removing 8 million cars from the road for a year”. Although rescinded before being fully implemented, this strategy had the potential to generate substantial revenue from oil and gas producers that could have been invested into furthering the fight against climate change. Additionally, it would have fostered innovation through the implementation of clean energy technologies, intensified the research and monitoring of methane emissions and contributed to overall cleaner air quality in the U.S.
 
Initiatives such as this, from large greenhouse gas emitting countries, serve as exemplary moves on the global stage. These strategies encourage other countries, especially those with oil and gas industries, to adopt similar policies that align with global climate initiatives. Thus, given Guyana’s booming oil and gas industry, policies such as methane emission fees will encourage environmentally friendly practices that will sustain low levels of greenhouse emissions.
