What is it?
There are hundreds of thousands of abandoned oil and gas wells around the world that were never properly sealed. These wells can leak methane, a potent greenhouse gas, directly into the atmosphere for decades. Projects in this category involve physically plugging and sealing these wells to stop the leakage.
Once properly capped with cement and other materials, the well is effectively sealed permanently, making this a highly durable form of emission avoidance. It also addresses a form of pollution that often occurs in rural or low-income areas, giving these projects meaningful co-benefits for local communities.
What does Deduci think?
Capping Abandoned Oil & Gas Wells and other projects targeting super pollutants, such as methane, have greatly increased in popularity over the past year. They are seen as high quality with their measurability and local impacts, and are regularly rated favorably by third-party rating agencies.
