Challenges in Addressing Methane Emissions
The significant increase in global methane emissions, which have risen over 20% in the last two decades, illustrates the challenges faced in combating climate change. This rise counters international commitments, such as the goal set in the Paris Agreement to reduce emissions significantly. The primary contributors to methane emissions are human activities, especially agriculture and landfills, with livestock being the biggest offender due to enteric fermentation. As methane is 80 times more potent than carbon dioxide in terms of warming the atmosphere, the ongoing increase represents a significant obstacle to achieving climate targets.
