Alteration of climate conditions is a distinct issue.
The fight against climate change is gaining momentum, with various countries and industries taking steps to reduce greenhouse gas emissions. However, one particular gas – methane – poses a significant challenge due to its potency in contributing to global warming.
Challenges
Insufficient financing and investment in methane abatement projects is a major hurdle. Despite methane abatement being cost-effective, global capital deployment is falling short of what is needed to meet targets such as a 75% reduction in oil and gas methane emissions by 2030.
Regulatory delays and political resistance also play a role. Delays in enacting or enforcing methane standards can lead to continued emissions and lost opportunities for clean air and energy savings. The livestock sector, for instance, resists changes like dietary shifts or feed additives to reduce methane from enteric fermentation, complicating agricultural methane mitigation.
Methane's invisibility and variability in emissions sources make detection and measurement difficult. This makes it hard to monitor and verify reductions accurately.
Potential Solutions
To address these challenges, several solutions are proposed. Mobilizing debt financing and increasing investment can accelerate the deployment of proven methane reduction methods, notably in oil and gas operations. Satellite-based instruments like MethaneSAT enable precise, wide-area monitoring of methane emissions, helping to identify and target major emitters.
Improved landfill management, through modernizing landfills with leak detection, gas collection, and diverting organic waste through composting and donation programs, can reduce waste methane significantly. Enacting and maintaining strict methane standards with clear compliance requirements, leak detection and repair mandates, and public accountability are critical.
Developing special feeds to reduce enteric methane, optimizing agricultural productivity, and encouraging dietary diversification especially in developed countries are important measures in agricultural methane mitigation.
Reducing methane emissions is viewed as a cost-effective and rapid strategy to curb near-term warming, due to methane’s high global warming potential and relatively short atmospheric lifetime (~12 years). Collective action across finance, regulation, technology deployment, and sectoral cooperation is vital to meet global climate goals.
The planned global expansion of hydrogen technology is an important pillar in the fight against climate change, but questions remain about its production. The IPCC stated in 2018 that the targets of the Paris Climate Agreement would not be achievable without Carbon Capture and Storage (CCS) projects. However, there are bottlenecks in the extraction of lithium for batteries, with currently known reserves and projects under construction only covering about half of the global lithium demand predicted by 2030.
In conclusion, while progress is being made in the fight against climate change, challenges remain, particularly in reducing methane emissions. Addressing these challenges requires collective action, investment, and innovation across various sectors. The race is on to find solutions that can help us reach our climate goals and secure a sustainable future for all.

- The fight against climate change involves not just general news, but also specific policies and legislation related to methane abatement, as highlighted by the Environmental Defense Fund (EDF).
- In the quest to reduce methane emissions, various sectors, including environmental science, play a crucial role. For instance, the United Nations Environment Programme (UNEP) emphasizes the importance of satellite-based instruments in monitoring methane emissions.
- Overcoming challenges such as insufficient financing and political resistance in the fight against climate change requires collaboration across industries, including politics and finance, as suggested by the Center for Climate and Energy Solutions (C2ES).
