Project details

Gas RecoveryGet to know the project

Santa Marta landfill is an existing and operational landfill site. It is located 17 km south of Chile's capital Santiago and started its operation in 2002. The site is suitable for municipal solid waste management and it is one of the most important landfills in the region, serving a population of around 1,200,000 inhabitants in the southern communes of Santiago. The total surface of the landfill is 296 hectares and it receives about 130,000 tonnes of domiciliary solid waste per month.

The project activity saves carbon emissions by capturing the landfill gas and utilizing it for electricity generation, reaching a total installed capacity of 28MW by the year 2023. The project includes electrical substations and a transmission line of 3.2 km to connect to the Chilean Interconnected Central System.

The main social and environmental impacts of the project will be renewable energy generation, reduction greenhouse gases and generation of a positive effects on health in the area. Furthermore, it contributes to employment creation and environmental education.

How does gas recovery contribute to climate action?

Methane is a greenhouse gas emitted by many processes including livestock farming, waste management, sewage treatment, oil production, and coal mining. When released into the atmosphere, it oxidises first to carbon monoxide and then to carbon dioxide, making it a major contributor to global warming. Climate projects avoid these emissions by capturing the gas and using it to generate heat or electricity, or by processing the gas into dry and liquid gas. In this way, the gas is not released into the atmosphere and is used to generate energy instead. Gas recovery projects in the ClimatePartner portfolio are registered with international standards.

The project aims to contribute to these United Nations’ Sustainable Development Goals (SDGs).

Project facts

Type
Reduction

Climate projects generally fall into one of three groups: carbon reduction, carbon removal, or carbon avoidance. Carbon reduction projects reduce the amount of greenhouse gas emissions produced by a specific activity (e.g., improved cookstoves). Carbon removal projects remove carbon from the atmosphere by sequestering it in carbon sinks (e.g., reforestation). Carbon avoidance projects avoid greenhouse gas emissions entering the atmosphere (e.g., protecting forests from deforestation with REDD+ projects).

Location
Chile, Santa Marta

Standard
Gold Standard

All climate projects are based on international standards. They set processes and requirements which carbon projects must fulfill to be recognised as a proven method of reducing carbon emissions.

Technology
Gas Recovery

Climate projects demonstrably reduce, remove, or avoid greenhouse gas emissions. This is achieved with various technologies, ranging from nature-based solutions to social impact projects and renewable energies.

Registry ID
3976

Most standards on the voluntary carbon market list their projects in public registries. The registries are used to store project data and track issuances and retirements of verified emission reductions. The registry ID can be used to identify projects in the standard registry.

Verified by
Spanish Association for Standardisation and Certification (AENOR)

Climate projects go through third-party validation and verification. Verification happens regularly after each monitoring period. A validation and verification body checks and assesses whether the values and project activities stated in the monitoring report are correct and verifies them. As with validation, visits to the project site are often part of the process.

Estimated annual emission reductions
350,000 t CO₂

This figure shows the estimated annual emission reductions calculated before the project started. The actual number of emissions saved in each monitoring period may differ. The background to this process is that in order to be registered as a climate project, the project operator must submit the calculation of the estimated emissions savings using the ex-ante methodology in a Project Design Document (PDD), which is similar to a business plan. This calculation is validated by an independent auditor. The values determined in the PDD are recalculated during regular monitoring periods based on actual project performance, documented in a monitoring report, and verified again by independent auditors at the end of the monitoring period to ensure a robust process. Independent verification thus provides ex-post verification of actual emission reductions. Verified emission reductions are not distributed until the savings have actually been made.

Four criteria for projects to meet quality thresholds

01. AdditionalityA project must lead to lower carbon emissions than would have occured without the project. Additionality also means that a project relies on financing from the sale of emission reductions, as the project would otherwise not be feasible and the upfront investment would be too high for project developers.

02. Exclusion of double countingThe carbon reduction may only be counted once and may not be counted again elsewhere, so a Verified Emission Reduction is retired once it has been used. This process is recorded in official registries.

03. PermanenceThe criterion of permanence ensures that carbon reductions or removals are ongoing and do not occur just once. This guarantees a long-term benefit for the climate. The minimum duration of a project depends on the underlying project technology.

04. Audit by independent third-partiesClimate projects must be audited regularly by independent auditors such as TÜV Nord. These auditors verify that the project is in compliance with the relevant standards. They also determine the volume of carbon emissions that have actually been avoided or removed.

The life cycle of a climate project

A climate project has a set life cycle consisting of various phases, from the feasibility assessment to the retirement of Verified Emission Reductions (VERs).

Project planning phase

The project developer reviews the general feasibility of the project, the project design, and the financing. Then, the Project Design Document (PDD) is prepared, which contains all the basic information about the project, such as the objective, location, timeline, and duration.

Validation

In this phase, independent auditors examine the PDD and the information it contains. This phase often also involves field visits with on-side interviews and analyses. Auditors are accredited, impartial assessors who have to be approved by the relevant standard as a validation and verification body (VVB). TÜV Nord/Süd, S&A Carbon LLC., and SCS Global Services are examples of VVBs."

Registration

Once validated, the project can be registered with a standard such as the Verified Carbon Standard or the Gold Standard. All high-quality climate projects are based on international standards. They provide the framework for project design, construction, carbon accounting, and monitoring. Recognised standards make the climate project system and the projects themselves resilient, traceable, and credible.

Monitoring

After the climate project has been registered, the monitoring begins. Here, the project developers monitor and document the data of the project activities and progress. The duration of the monitoring phase varies from project to project: it can cover two years, but documentation over five or seven years is also possible.

Verification

At the end of each monitoring phase, a VVB checks and assesses whether the values and project activities stated in the monitoring report are correct. As with validation, visits to the project site are often part of the verification process.

Issuance of Verified Emission Reductions

Once verified, the emission reductions that were confirmed in the verification phase can be issued as VERs. The steps of monitoring, verification, and issuance of VERs are repeated regularly and are therefore considered as a cycle.

Retirement of Verified Emission Reductions

Once a VER has been used, it must be retired. This process is also reflected in the registry. If the financing of a climate project is done through ClimatePartner, the VERs are bundled in a system certified by TÜV Austria and then retired on a regular basis. This ensures that each VER can no longer be sold and is only used once, preventing double counting.
