Mitigating Methane Pollution: Strategies For A Sustainable Future

Methane pollution is a pressing issue, with the energy sector responsible for more than a third of global methane emissions. The oil and gas industry is the largest contributor, with methane escaping into the atmosphere through intentional flaring and venting, as well as unintentional leaks. As methane is a potent greenhouse gas, reducing methane emissions is critical to slowing climate change and limiting global warming. This can be achieved through leak detection and repair programs, implementing better technologies, and capturing and utilizing methane.

Reducing methane emissions from the energy sector

The energy sector is responsible for more than a third of global methane emissions, with oil and gas contributing the lion's share (around 14%). Methane emissions occur along the entire oil and gas supply chain, but especially from fugitive emissions from leaking equipment, system upsets, and deliberate flaring and venting.

Existing cost-effective solutions can help reduce emissions, including initiating leak detection and repair programs, implementing better technologies and operating practices, and capturing and utilizing methane that would otherwise be wasted. For example, advances in methane detection technology have allowed previously undetected leaks to be identified.

The Environment Agency in the UK has developed a Methane Action Plan to reduce methane emissions through regulation, knowledge-sharing, and good practice. Similarly, the Environmental Defense Fund has partnered with Google Earth Outreach to help utilities find and fix methane leaks under city streets. These initiatives demonstrate the importance of collaboration and the sharing of best practices to reduce methane emissions from the energy sector.

Reducing methane emissions from oil and gas operations

The energy sector is responsible for more than a third of global methane emissions, with oil and gas contributing around 14%. Methane emissions occur along the entire oil and gas supply chain, but especially from fugitive emissions from leaking equipment, system upsets, and deliberate flaring and venting.

To reduce methane emissions from oil and gas operations, existing cost-effective solutions can be implemented. These include:

• Initiating leak detection and repair programs
• Implementing better technologies and operating practices
• Capturing and utilizing methane that would otherwise be wasted

The International Energy Agency estimates that around 75% of total oil and gas methane emissions can be avoided using currently available technologies, with more than half of these reductions at zero net cost.

In addition to the above measures, the following actions can also be taken:

• The Environment Agency in the UK has a Methane Action Plan that aims to reduce methane emissions through regulation and sharing knowledge and good practice internationally.
• MethaneSAT, a subsidiary of the Environmental Defense Fund, has launched a satellite to map, measure and track methane emissions worldwide. They have also partnered with Google Earth Outreach to get utilities to find and fix methane leaks under city streets.
• Advances in methane detection technology allow for the identification of previously undetected leaks, helping to reduce fugitive emissions.

Capturing and controlling methane emissions from landfill sites

Methane is a priority pollutant requiring capture and control. This can be achieved through regulatory requirements that also help control methane, as well as supporting industries to develop voluntary actions, such as industry codes of practice, or by sharing information and research on reducing emissions.

In addition to capturing and controlling methane emissions from landfill sites, it is also important to address methane emissions from the energy sector, particularly the oil and gas industry. Existing cost-effective solutions can help reduce emissions, including leak detection and repair programs, implementing better technologies and operating practices, and capturing and utilizing methane that would otherwise be wasted.

The International Energy Agency estimates that around 75% of total oil and gas methane emissions can be avoided using currently available technologies, with more than half of these reductions at zero net cost. By acting now to reduce methane emissions, we can have immediate benefits to the climate that reductions in carbon dioxide alone cannot provide.

Detecting and repairing methane leaks

To detect and repair methane leaks, existing cost-effective solutions can be implemented. These include initiating leak detection and repair programs, improving technologies and operating practices, and capturing and utilising methane that would otherwise be wasted. The International Energy Agency estimates that around 75% of total oil and gas methane emissions can be avoided using currently available technologies, with more than half of these reductions at zero net cost.

Advances in methane detection technology have allowed previously undetected leaks to be identified. For example, MethaneSAT, a subsidiary of the Environmental Defense Fund, launched a satellite to map, measure and track methane emissions worldwide. They also partnered with Google Earth Outreach to help utilities find and fix methane leaks under city streets.

In addition to the energy sector, other sectors such as water companies, farmers, and landfill sites also contribute to methane emissions. The Environment Agency in the UK, for example, has a Methane Action Plan to reduce methane emissions through regulatory requirements, voluntary actions, and sharing information and research.

Reducing methane emissions from water companies and farmers

Methane pollution is a pressing issue, and reducing methane emissions is crucial to slowing climate change. Water companies and farmers can play a significant role in mitigating methane pollution by implementing various measures.

Water companies can start by addressing leaks in their systems, as methane emissions often occur due to leaking equipment. Detecting and repairing these leaks can significantly reduce methane emissions. Additionally, water companies can improve their operating practices and adopt better technologies to minimise methane releases. Capturing and utilising methane that would otherwise be wasted is another effective strategy. By implementing these measures, water companies can contribute to reducing methane pollution.

Farmers also have a crucial role in reducing methane emissions. They can start by complying with regulatory requirements aimed at controlling methane emissions. This includes following industry codes of practice and adopting recommended practices to reduce emissions. Additionally, farmers can voluntarily take action by participating in knowledge-sharing initiatives and staying informed about the latest research on emission reduction. By working together with regulatory bodies and adopting sustainable practices, farmers can make a significant impact on mitigating methane pollution.

Both water companies and farmers can benefit from partnerships and collaborations aimed at reducing methane emissions. Working with environmental organisations and regulatory bodies can provide access to resources, expertise, and best practices. By sharing knowledge and learning from each other's experiences, both sectors can develop more effective strategies to tackle methane pollution.

Furthermore, addressing methane emissions from the energy sector, specifically oil and gas operations, is vital. The energy sector accounts for a significant portion of global methane emissions, and reducing emissions from this industry is crucial. Oil and gas companies can minimise methane releases by eliminating wasteful practices such as intentional flaring and venting. By adopting more sustainable practices and technologies, the energy sector can significantly contribute to the reduction of methane pollution.

In conclusion, water companies and farmers can take proactive steps to reduce methane emissions by implementing a combination of regulatory compliance, voluntary actions, and collaborative efforts. By addressing leaks, adopting better technologies, and sharing knowledge, they can play a significant role in mitigating methane pollution and contributing to global efforts to combat climate change.
