Though less photogenic than some of their carbon offset project counterparts, landfill gas projects play an essential role in the offset ecosystem, primarily by reducing emissions of methane, a greenhouse gas 28 times more potent than carbon dioxide. In Elba, Alabama, the Coffee County Sanitary Landfill has invested in being part of the climate solution by installing a system to collect and combust landfill gas before it can escape into the atmosphere. Without this project and its control of methane emissions, this county landfill would be a significant methane emission source.
There are 48 vertical wells installed within the Coffee County Landfill, with depths that ranging from 12 feet to 88 feet. A blower creates a vacuum that draws the landfill gas from these wells to the main collection header, where the landfill gas is combusted via a flare. The system now meets the rigorous performance standard defined by the Climate Action Reserve landfill gas protocol.
In addition, the landfill’s Non-Methane Organic Compound (NMOC) emissions rate was measured to be 5.3 Mg/yr. (megagrams per year), well below the 50 Mg/yr that would trigger mandatory control of this landfill’s emissions.
The project’s offset calculus accounts for three voluntarily installed passive flares that were used for positive pressure release and odor control prior to the project’s start date. All discounts for pre-project destruction devices were accounted for in the baseline emissions for the current reporting period, and were verified during the project’s initial reporting period.
Looking forward, Coffee County is now planning to use this infrastructure to add an additional layer to its landfill gas recapture program by selling the captured methane as a reusable energy source to a Florida-based recycling company, rather than flaring it off directly. This utilizes energy from burning the methane that would have otherwise gone wasted, and creates a revenue stream for the county government and local area.
The coastal areas of Afognak Island are home to 200-year old forests, river otters, beavers, martens and ermines. Offshore in the coastal waters, sea lions and harbor seals swim in sight of humpback whales. This pristine environment also has an increasingly important environmental value: the old-growth trees sequester millions of tonnes of carbon dioxide. This creates a new resource opportunity for the forest and habitat based on their environmental benefits.
Afognak Island has retained large tracts of undisturbed native trees (180-250 years old) along with regenerated growth of trees over the past 30 years. Afognak is also home to Alaska’s largest herd of elk. The Afognak Forest Carbon Project represents over a decade’s worth of dedicated efforts by dozens of individuals, in partnership with the Rocky Mountain Elk Foundation and the American Land Conservancy, to conserve a truly unique ecosystem in perpetuity. In 2008, this pioneering effort affected a shift from timber production management to conservation management across the five parcels that constitute the Afognak Project. The Afognak forest carbon project represents the first project of its kind in the state of Alaska.
Kodiak bears and Native peoples co-existed for centuries on the island before the towering Sitka spruce trees first took hold some 800 years ago. The first European laid eyes on Afognak Island in 1741 and Russian fur trappers soon followed. Beginning in the 19th century, Americans were increasingly concerned with the destruction of wildlife and saw value in conservation. Yosemite, Yellowstone and Afognak Island were seen as irreplaceable wilderness worth preserving. Thanks to President Theodore Roosevelt, in 1907, Afognak Island was offically designated as a National Forest. Protecting Native Species Afognak is home to many species endemic to Alaska: Roosevelt Elk, Pacific Salmon, Steelhead, Rainbow Trout, Arctic Char, Dolly Varden, Kodiak Brown Bear, Bald Eagle, Marbled Murrelet, River Otter, Tundra Vole, Sitka-black Tailed Deer, Mountain Goat and Snowshoe Hare. The preservation of natural forest habitat is important for the continued survival of these species. .
Environmental co-benefits include the prevention of land disruption and the greenhouse gas emissions from timber logging. The project restores and protects habitat for native plant, mammal, bird and fish species.
La Perseverancia Landfill is an excellent example of how a landfill gas (LFG) collection and destruction system can have multiple uses. The project destroys methane (biogas), a potent greenhouse gas, in a controlled and measured manner. The project also provides renewable electricity, and opportunities for community education.
La Perseverancia landfill, located in Cuautla, Morelos collects waste from 13 municipalities in the state of Morelos. Cuautla is about 75 km South of Mexico City, south of El Tepozteco National Park. The development of this project is an example of a carefully negotiated effective public/private partnership between the municipality of Cuautla and Operadora de Ferrocarril y Manejo de Rellenos SA de CV. This biogas to energy plant provides environmental, social and economic benefits. It is a winner of the Guangzhou International Award for Urban Innovation.
The management of municipal waste is a challenge. Many of us don’t know, or want to think about the end of life of our trash. La Perseverancia is a leader in sustainable development for waste management.
Five cells within the landfill are fitted with vertical and horizontal extraction wells. The project has a blower that provides flow of the biogas into the destruction devices. Data from flow meters are automatically recorded every 15 minutes. This monitoring is continuous throughout the reporting period.
A “knock out pot” is used to capture condensate in the biogas, enabling better engine operation. Electricity is produced from a biogas fueled 4-stroke engine, which is connected to a generator. The engine, fueled by the collected biogas is capable of running on such a rich burning fuel. The facility also has a backup flare that can only be used when the engine/generator isn’t running. All methane collected by the system is destroyed in one of these two devices.
The project has provided new employment opportunities, creating jobs at all levels of education and skills. Through collaboration agreements with local universities, students are able to intern, learning about sustainable waste management at this innovative project. Students get professional experience in waste to energy development.
The project also cooperates with international partners.
“The innovative part of this project has caught the attention of the region of Tolima in Colombia and a South-South cooperation project has taken place with the support of both Cooperation Agencies of Mexico and Colombia supporting the exchange happening between the two local governments in the field of solid waste management and the best practices.”
The Project reduced emissions into the atmosphere by 12,501 metric tons CO2-e for the reporting period 15 June 2016 through 14 June 2017. The project’s crediting period will continue through 2024. This project meets all the requirements of Climate Action Reserve’s Mexico Landfill Project Protocol, Version 1.1
The Kulera Landscape project provides 5-km buffer areas around three important nature reserves in the African nation of Malawi: Nyika National Park, Vwaza Wildlife Reserve, and the Nkhotakota Wildlife Reserve, including a total project area of 217,270 hectares. These buffer zones protect forests and biodiversity, provide for improved regional governance, and facilitate sustainable forestry and agriculture in the project region. The project’s carbon credits are developed from the careful accounting and independent third-party verification of the carbon sequestered through growing trees in the project zone.
Encroachment and deforestation of the protected areas (typically for the procurement of wood and other resources) is now significantly mitigated by enhanced enforcement. This is done hand-in-hand with addressing the environmental, social and economic needs of local communities (such as the indigienous Chewa people) to provide alternative and sustainable livelihoods.
The Kulera project formally includes the Malawi Department of Natural Parks and Wildlife and the communities as project proponents. The project provides for the formation of Community Associations with democratically elected representatives from villages around the protected areas. Through this governance, the communities are empowered to actively engage with its lawful and contractual obligations. The communities are active participants in implementing sustainable agriculture and forestry, distribution and use of efficient cookstoves, and enforcement against poaching. Community members have also received training on conservation agriculture, natural resource management, tree regeneration, establishment of tree nurseries, and tree planting. The project provides training in business skills and marketing for entrepreneurs. Alternative energy and fuel-efficiency solutions are also being introduced into the region.
Malawi is a sub-tropical land-locked country of high mountains and deep lakes in southeast Africa. One-fifth of it is covered by Lake Malawi, which fills the trough of the Great African Rift Valley that traverses the country from north to south. East and west of the lake, the land forms high plateaus that reach as high as 2,600 meters in the Nyika uplands, and 3,048 meters at Mount Mulanje.
Malawi ranks among the world’s least developed countries. About 80% of the population lives in rural areas, with agriculture accounting for a third of the country’s GDP and 80% of the country’s exports. With almost 20 million people, slowing, but still rapid population growth continues to put pressure on Malawi’s land, water, and forest resources. Reduced plot sizes and increasing vulnerability to climate change threatens the sustainability of Malawi’s agriculturally based economy and will worsen food shortages.
Malawi’s highland forests, rivers, and Lake Malawi provide important habitat for many diverse species of flora and fauna. The country is home to elephants, baboons, black rhinos, buffalos, waterbucks, bushbucks, crocodiles, hippos, Livingstone’s eland, Lichtenstein’s hartebeest, sable antelope, nyala, Burchell’s zebra, impala, warthog, and more.
The Kulera Landscape project is registered with the Verra Verified Carbon Standard (VCS) and Climate, Community, and Biodiversity Standard (CCB). In addition, as a REDD+ verified project (REDD+ stands for Reduce Emissions from Deforestation and Forest Degradation), it meets high standards established by the REDD+ international framework for forest management programs and associated co-benefits such as environmental conservation and restoration, economic stimulus, training, and entrepreneurship opportunities.
