Award-winning programme uses carbon credits to deliver safe water in Kenya
In 2011, nearly 900,000 water filters were distributed to households in Western Kenya, promising access to safe drinking water for 4.5 million people. Oxford University is leading research to evaluate the programme’s impact on diarrhoea, dysentery and dehydration among children under five and people living with HIV.
LifeStraw® Carbon for Water is an innovative public health programme which distributes LifeStraw Family water filters to households in Western Kenya, enabling citizens to safely treat water in their own home.
The ten-year programme is implemented by the private company Vestergaard Frandsen in partnership with the Kenyan Government. It is one of the largest water treatment programmes realised without public-sector funding, and the first ever to be supported by carbon financing.
By using LifeStraw filters, families no longer need to purify their water through boiling, which means less firewood is burned as fuel. Vestergaard Frandsen claims carbon credits for the greenhouse gas emissions saved, which can then be sold and the revenue used to cover programme costs.
Crucially, carbon credits can only be obtained once it is shown that the filters are being regularly used. The certification methodology was designed by the Oxford-based organisation ClimateCare, and ensures that the programme delivers real and long-lasting sustainable development benefits. This results-driven system incentivises important investments in health education and robust monitoring systems.
The programme was chosen by the United Nations Climate Framework Convention on Climate Change (UNFCCC) as one of their landmark ‘lighthouse activities’ which help developing countries to curb their greenhouse gas emissions or adapt to climate change. It will be showcased at the COP18 Climate Change Conference in Doha, Qatar, at the end of November.
It is expected that the use of LifeStraw, alongside the provision of health and hygiene education, will significantly reduce the risk of contamination and illness. Dr John Haskew, an Academic Clinic Fellow at Oxford University’s Department for Public Health, is leading the health impact evaluation, which makes use of cutting-edge mobile phone technology and electronic medical records.
The health impact studies focus on populations most vulnerable to water-borne diseases. The Oxford-led team is evaluating the impact of the programme on diarrhoea and dehydration among children under five years old. They will also establish whether the use of LifeStraw can reduce rates of diarrhoea and infection among people with HIV, and even delay the development of the HIV disease itself.
