Global action against methane emissions

At the end of September, representatives from 66 countries met at the Global Methane, Climate, and Clean Air Forum, in Washington D.C. with four objectives: (1) show the most recent evidence on methane emissions’ effects on health and their contribution to global warming, (2) reaffirm that reduction of methane emissions in 2030 is necessary to avoid global warming above 1.5°C in 2050, (3)present the actions by governments, NGOs and multilateral organizations to accelerate the mitigation of methane emissions, (4)show the scientific advances in the detection, quantification, and reduction of methane emissions. In this one-pager, we share the general conclusions of the first two objectives; the rest will be treated in subsequent publications.

Methane emission reduction targets

According to the GMA-21, limiting global warming to 1.5°C in 2050 requires reducing anthropogenic methane emissions by 45% (180 million tons per year – Mt/year) by 2030. This requires two types of actions depending on their availability and mitigation potential: (1) Currently Available Measures and (2) Additional Potential Measures. The first refer to the actions available in the market that can reduce emissions at a very low or even negative cost (e.g., gas leaks). The second type of actions can contribute significantly to the coming decades (e.g., transition to renewables and energy efficiency). For more detail, see Measures (right). 

Currently available measures can reduce emissions from these three sectors by approximately 45% (180 Mt/year) in 2030. About 60% (75Mt/year) of targeted measures have low mitigation costs, and slightly more than 50% have a negative cost (i.e., they represent a revenue). These measures are available mainly for three sectors: oil and gas (from 60% to 80%), coal mining (55% to 98%), and waste (30% to 60%). On the other hand, technology availability in the agricultural sector limits the reduction potential to 30 Mt/year. However, Cultural Change (reducing food waste, improving livestock management, and adopting diets lower in meat and dairy) has a majot potential in a couple of decades.

Final comment

Due to their availability, the measures in the hydrocarbon sector are the ones with the larger potential because, unlike other sectors, methane recovery represents an instantaneous revenues for companies that stop emitting it. That is why the lack of progress cannot be justified from any point of view. According to this, diverse international agencies have estimated that oil and gas sector can reduce 75% of methane emissions in 2030. Countries like the US and Canada are implementing highly ambitious policies for oil and gas industry to reduce their emissions drastically. In the next one-pager, we will present the progress of these two countries in their policies to reduce methane emissions.

Currently Available Measures.

30% reduction in emissions in 2030.

  • LDAR in upstream and downstream.
  • Recovery and use of vented gas.
  • Increase emissions control in oil and gas production (e.g., installing vapor recovery units, plugging of abandoned wells, replacing pneumatic pumps and controllers, and seals in compressors, among others).
  • Improve  coal  mine  management (degasification and recovery of gas before starting exploitation, methane oxidation, flooding of abandoned mines).
  • Solid  waste  management  (separating garbage at home, recycling, burning gas in landfills, etc.).
  • Waste-water treatment.
  • Reduce enteric fermentation of cattle with food supplements.
  • Improve manure management (treatment in  biodigesters,  optimization  time  of storage, acidification, etc.).
  • Improve water management in rice fields. Avoid burning crop residues.

Additional Potential Measures.
30% reduction in emissions in 2030.

  • Switch to renewable energy.
  • Increase energy efficiency in homes and businesses.
  • Reduce food waste and garbage.
  • Healthier diets (less meat and dairy).
  • Implementing a tax of USD$800 per ton of emitted methane can reduce emissions by up to 75% by 2050.
  • Cooperate  to  increase  knowledge  of methane emissions policies, management of emissions and best regulatory practice.
  • Improvement  of  regional  and  global coordination for reach the goal in 2030.

At Grupo Talanza we are committed to supporting the oil industry to reduce its emissions. We are pioneers in Mexico in the detection and quantification of methane emissions, authorized third parties of the ASEA for methane, and international advisors in the regulation of methane emissions.
