Social and environmental impact of palm oil
Palm oil, produced from the oil palm, is a basic source of income for many farmers in South East Asia, Central and West Africa, and Central America. It is locally used as a cooking oil, exported for use in many commercial food and personal care products and is converted into biofuel. It produces up to 10 times more oil per unit area than soyabeans, rapeseed or sunflowers. Oil palms produce 38% of the world's vegetable-oil output on 5% of the world’s vegetable-oil farmland. Palm oil plantations are under increasing scrutiny for their effects on the environment, including loss of carbon-sequestering forest land. There is also concern over displacement and disruption of human and animal populations due to palm oil cultivation.
As of 2006, the cumulative land area of palm oil plantations is approximately 11,000,000 hectares (42,000 sq mi). In 2005 the Malaysian Palm Oil Association, responsible for about half of the world's crop, estimated that they manage about half a billion perennial carbon-sequestering palm trees. Demand for palm oil has been rising and is expected to climb further.
Between 1967 and 2000 the area under cultivation in Indonesia expanded from less than 2,000 square kilometres (770 sq mi) to more than 30,000 square kilometres (12,000 sq mi). Deforestation in Indonesia for palm oil (and illegal logging) is so rapid that a 2007 United Nations Environment Programme (UNEP) report said that most of the country’s forest might be destroyed by 2022. The rate of forest loss has declined in the past decade.
Global production is forecast at a record 46.9m tonnes in 2010, up from 45.3m in 2009, with Indonesia providing most of the increase.
Oil palm is a valuable economic crop and provides a source of employment. It allows small landholders to participate in the cash economy and often results in improvements to local infrastructure and greater access to services such as schools and health facilities. In some areas, the cultivation of oil palm has replaced traditional practices, often due to the higher income potential of palm oil.
However, in some cases, land has been developed by oil palm plantations without consultation or compensation of the indigenous people occupying the land. This has occurred in Papua New Guinea, Colombia, and Indonesia. In the Sarawak state of Malaysian Borneo, there has been debate over whether there was an appropriate level of consultation with the Long Teran Kanan community prior to the development of local land for palm oil plantations. Appropriation of native lands has led to conflict between the plantations and local residents in each of these countries.
According to a 2008 report by NGOs including Friends of the Earth, palm oil companies have also reportedly to used force to acquire land from indigenous communities in Indonesia. Additionally, some Indonesian oil palm plantations are dependent on imported labor or illegal immigrants, which has raised concerns about the working conditions and social impacts of these practices.
In Indonesia, rising demand for palm oil and timber, have led to the clearing of tropical forest land in Indonesian national parks. According to a 2007 report published by UNEP, at the rate of deforestation at that time, an estimated 98 percent of Indonesian forest would be destroyed by 2022 due to legal and illegal logging, forest fires and the development of palm oil plantations. Neighboring Malaysia, the second largest producer of palm oil, has pledged to conserve a minimum of 50 percent its total land area as preserved forests. As of 2010, 58 percent of Malaysia land was forested. Palm oil cultivation has been criticized for:
- Greenhouse gas emissions. Deforestation in tropical areas accounts for an estimated 10 percent of manmade CO
2 emissions, and is a driver toward dangerous climate change.
- Habitat destruction, leading to the demise of critically endangered species (e.g. the Sumatran tiger, the Asian rhinoceros, and the Sumatran Orangutan.)
- Reduced biodiversity, including damage to biodiversity hotspots.
- Cultivating crops on land that belongs to indigenous people in the Sarawak and Kalimantan states on the island of Borneo and the Malaysian state of Sabah.
In some states where oil palm is established, lax enforcement of environmental legislation leads to encroachment of plantations into riparian strips, and release of pollutants such as Palm Oil Mill Effluent (POME) in the environment. More environment-friendly practices have been developed. Among those approaches is anaerobic treatment of POME, which can be a good source for biogas (methane) production and electricity generation, if carefully managed to maintain optimum growth conditions for the anaerobic organisms that break down acetate to methane (primarily Methanosaeta concilii, a species of Archaea).
Greenhouse gas emissions
Damage to peatland, partly due to palm oil production, is claimed to contribute to environmental degradation, including four percent of global greenhouse gas emissions and eight percent of all global emissions caused annually by burning fossil fuels, due to the clearing of large areas of rainforest for palm oil plantations. Many Indonesian and Malaysian rainforests lie atop peat bogs that store great quantities of carbon. Forest removal and bog drainage to make way for plantations releases this carbon.
Environmental groups such as Greenpeace claim that this deforestation produces far more emissions than biofuels remove. Greenpeace identified Indonesian peatlands, unique tropical forests whose dense soil can be burned to release carbon emissions, that are being destroyed to make way for palm oil plantations. They represent massive carbon sinks, and they claim their destruction already accounts for four percent of annual global emissions. However, according to the Tropical Peat Research Laboratory, at least one measurement has shown that oil palm plantations are carbon sinks because oil palms convert carbon dioxide into oxygen just as other trees do, and, as reported in Malaysia's Second National Communication to the United Nations Framework Convention on Climate Change, oil palm plantations contribute to Malaysia's net carbon sink.
Greenpeace recorded peatland destruction in the Indonesian province of Riau on the island of Sumatra, home to 25 percent of Indonesia's palm oil plantations. Growers plan to expand the area under concession by more than 28,500 square kilometres (11,000 sq mi) which would deforest half of the province. Greenpeace claims this would have devastating consequences for Riau's peatlands, which have already been degraded by industrial development and store a massive 14.6 billion tonnes of carbon, roughly one year's greenhouse gas emissions.
Research conducted by Greenpeace through its Forest Defenders Camp in Riau documents how a major Indonesian palm oil producer is engaging in large-scale, illegal destruction of peatland in flagrant violation of an Indonesian presidential order, as well as national forestry regulations. Palm oil from peatland is fed into the supply chain for global brands. FoE and Greenpeace both calculate that forests and peatlands that are replaced by palm oil plantations release more carbon dioxide than is saved by replacing diesel with biofuels.
Environmentalists and conservationists have been called upon to team up with palm-oil companies to purchase small tracts of existing palm plantation, so they can use the profits to create privately owned nature reserves. It has been suggested that this is a more productive strategy than the current confrontational approach that threatens the livelihoods of millions of smallholders.
Indonesia and Malaysia
In the two countries responsible for over 80% of world oil palm production, Indonesia and Malaysia, smallholders account for 35–40% of the total area of planted oil palm and as much as 33% of the output. Elsewhere, as in West African countries that produce mainly for domestic and regional markets, smallholders produce up to 90% of the annual harvest.
As a result of Malaysia's commitment to retain natural forest cover on at least 50 percent of the nation's land, the growth of new palm oil plantations has slowed in recent years. According to Malaysia's Plantation Industries and Commodities Minister Bernard Dompok, significant expansion of palm oil is no longer possible, therefore Malaysian farmers are now focusing on increasing production without expansion. In January 2008, the CEO of the Malaysian Palm Oil Council wrote a letter to the Wall Street Journal stating that Malaysia was aware of the need to pursue a sustainable palm oil industry. Since then the Malaysian government, along with palm oil companies, have increased production of Certified Sustainable Palm Oil (CSPO). Malaysia has been recognized by the Roundtable on Sustainable Palm Oil as the largest producer of CSPO, producing 50 percent of the world's supply, and accounting for 40% of CSPO growers worldwide. Indonesia produces 35 percent of the world's CSPO.
In Africa, the situation is very different compared to Indonesia or Malaysia. In its Human Development Report 2007-2008, the United Nations Development Program says production of palm oil in West-Africa is largely sustainable, mainly because it is undertaken on a smallholder level without resorting to diversity-damaging monoculture. The United Nations Food and Agriculture program is encouraging small farmers across Africa to grow palm oil, because the crop offers opportunities to improve livelihoods and incomes for the poor.
Food and cosmetics companies, including ADM, Unilever, Cargill, Procter & Gamble, Nestle, Kraft and Burger King, are driving the demand for new palm oil supplies, partly for products that contain non-hydrogenated solid vegetable fats, as consumers now demand fewer hydrogenated oils in food products that were previously high in trans fat content.
Although palm oil is used in the production of biofuels and proposals have been made to use it in large installations, a 2012 report by the International Food Policy Research Institute concluded that the increase in palm oil production is related to food demands, not biofuel demands.
Biodiesel made from palm oil grown on sustainable non-forest land and from established plantations effectively reduces greenhouse gas emissions. According to Greenpeace, clearing peatland to plant oil palms releases large amounts of greenhouse gasses, and that biodiesel produced from oil palms grown on this land may not result in a net reduction of greenhouse gas emissions. However, research by Malaysia's Tropical Peat Research Unit has found that oil palm plantations developed on peatland produce lower carbon dioxide emissions than forest peat swamp.
In 2011, eight of Malaysia's Federal Land Development Authority (FELDA) plantations were certified under the International Sustainability and Carbon Certification System (ISCC), becoming part of Asia's first ISCC certified supply and production chain for palm biodiesel. This certification system complies with the European Union's Renewable Energy Directive (RED). In 2012, the European Commission approved the RSPO's biofuel certification scheme allowing certified sustainable palm oil biofuel to be sold in Europe.
The Roundtable on Sustainable Palm Oil (RSPO), founded in 2004, works to promote the production of sustainably sourced palm oil through involvement with growers, processors, food companies, investors and NGOs. Beginning in 2008, palm oil that meets RSPO introduced standards has been designated certified sustainable palm oil (CPSO). Within two years of implementation CSPO designated palm oil comprised 7 percent of the global palm oil market. As of October 2012, 12 percent of palm oil has been certified by the RSPO. However, in the first year of CSPO certification only 30 percent of sustainable oil was marketed as CSPO.
In The Economist in 2010, the RSPO was criticized for not setting standards for greenhouse-gas emissions for plantations and because its members account for only 40 percent of palm oil production. In a 2007 report, Greenpeace was critical of RSPO-member food companies saying that they are "dependent on suppliers that are actively engaged in deforestation and the conversion of peatlands".
Following a contribution of $1 billion from Norway, in May 2010, Indonesia announced a two-year suspension on new agreements to clear natural forests and peatlands. Additionally, Indonesia announced plans to create its own organization similar to the RSPO, which, as a government certification system, will introduce mandatory regulation for all Indonesian palm oil producers. In 2011, Malaysia also began developing a national certification, the Malaysia Sustainable Palm Oil (MSPO) certification, to improve involvement in sustainable palm oil production nationwide.
Carbon credit programs
Oil palm producers are eligible to take part in Clean Development Mechanism (CDM) programs in which developed nations invest in clean energy projects in developing nations to earn carbon credits to offset their own greenhouse gas emissions and to reduce greenhouse gas emissions worldwide.
Investors have been cautious about investing in palm oil biofuel projects because of the impact the expansion of oil palm plantations has had on tropical rain forests, but according to the South East Asian CDM development company YTL-SV Carbon, many CDM projects in the palm oil sector focus on improving use of waste products to reduce gas emissions and do not contribute to the establishment of new oil palm plantations.
Use of sustainable oil by corporations
The World Wildlife Foundation (WWF) publishes an annual report on the use of sustainable palm oil by major corporations. In the 2011 report, 31 of the 132 companies surveyed received a top score for their use of sustainable palm oil. This represents an increase from 2009, the first year the report was issued, where no companies received top scores.
The WWF reports that 87 companies have committed to using only sustainable palm oil by 2015, including Unilever and Nestlé, both of which committed to exclusively using sustainable palm oil following demonstrations and urgings from environmental organizations in the late 2000s. However, according to the WWF, the overall growth in the use of sustainable palm oil is too slow. Retailers who have made commitments to offering products containing sustainable oil, including Walmart and Carrefour, have attributed the slow rate of growth in the availability of sustainable palm oil to a lack of consumer interest and awareness in products made with sustainable palm oil. These companies have expressed concern about the potential impact of low consumer demand on the cost and future availability of sustainable palm oil.
It may be possible to persuade governments of nations that produce competing products to enact protectionist legislation against the products of deforestation, an approach that was presented in a report by the National Farmers Union (United States) and Avoided Deforestation Partners. The 2010 report estimates that protecting the 13,000,000 hectares (50,000 sq mi) of mostly tropical forest that are lost annually worldwide would boost American agricultural revenue by $190–270 billion between 2012 and 2030. However, several conservation groups, including Conservation International, Environmental Defense Fund, National Wildlife Federation, and The Nature Conservancy, presented a rebuttal to the report, stating that it was "based on the assumption, totally unfounded, that deforestation in tropical countries can be easily interrupted, and its conclusions are therefore also unrealistic."
