HEALTH109rich countries is highly energy intensive, whilehundreds of thousands of health clinics in Africa, Asiaand Latin America have no power at all. If such clinicscould be supplied with renewable electricity for basicneeds from solar panels, the quality of health carecould potentially be improved, at little long term costto the planet.Recognising these realities, the health sector is already"leading" with its own "greening" initiatives. Hospitalsin a number of Chinese cities recently launchedprogrammes to promote "green and safe" hospitals -that can function better in emergencies. From theUK's National Health Service to small NGOs at thegrassroots, health facilities are launching energy auditsand examining how carbon efficiencies can benefitboth the planet and health."ADAPTIVE" MITIGATIONInitiatives for "green and safe" hospitals recognise thatmany measures that "mitigate" against future climatechange can also be integrated with measures thatimprove adaptation to the impacts of climate changealready being felt. Other such "adaptive mitigation"measures could include:Integrated vector management, which combinesenvironmental management with wise use ofchemicals, can help combat climate change-inducedchanges in vector borne disease transmission, whilealso reducing long-term environmental impact ofchemicals (van den Berg et al, 2007; Campbell-Lendrum, et al, 2005).Greener urban development could improve homesitting and construction to better protect from heatwaves, flooding and mudslides that may be caused byclimate change - while also improving access to publictransport, walking and cycling, to mitigate againstfuture climate change.VALUING HEALTH IN THE CLIMATECHANGE DEBATE The original United Nations Framework Convention onClimate Change (UN, 1992) notes "adverse effects ofclimate change on the economy, public health and thequality of the environment" as the three critical sets ofimpacts that the international climate effort isdesigned to avoid. The Intergovernmental Panel onClimate Change notes that the immediate healthbenefits of reduced air pollution could pay for much ofthe cost of greenhouse gas mitigation measures.Despite this, only approximately one per cent of theinternational funding on climate change currently goesto protect health. Almost all of the economic modelsthat attempt to guide decision-making on greenhouse?

gas emission reductions exclude health co-benefits.And health gains are not considered in the UNFCCCclean development mechanisms used to finance manytypes of low-carbon development. Taken together, thisleads to a bias against greener policy decisions, and amissed opportunity for health, for the environment,and for the economy.WHO believes this can change. Initial findings fromWHO's series of reviews on Health in the GreenEconomy cover the potential co-benefits to health of mitigation action in: agriculture, transport,household energy, residential construction and healthcare facilities.These reviews summarise current knowledge andidentify important opportunities for re-thinking,strengthening, or fine-tuning existing policies to both enhance health and reduce our global carbon footprint.But this is only a first step. Our aim is to make thestrategic, political and scientific case for placinggreater emphasis on the health dimension as a way toimprove, relevance, and effectiveness of climatepolicy. A new and strengthened health focus, webelieve, can revitalise public engagement, and lead tofuture climate policies that take the biggest step yettowards global health in human history. nABOUT THE AUTHORDr Maria P.
