February 13, 2012. Osmosis Investment Management LLP said investors are more prepared to buy into riskier climate- related businesses that seek resource efficiency amid population growth and higher oil prices. Osmosis tracks companies active in low-carbon services and technologies through the Osmosis Climate Solutions Index. The index is showing early signs of growth after underperforming in the past few years. Investor appetite for companies that use resources efficiently is being driven by rising middle-class consumption and higher fossil-fuel costs. This comes as renewable energy investments rose to a record $260 billion last year, boosted by a surge in solar developments. As some European governments cut clean energy subsidies to tackle austerity measures, businesses have restructured, emerging as well-managed companies. The Osmosis index follows 100 companies including Renewable Energy Corp ASA, EDP Renovaveis SA and LDK Solar Co. in the renewables and low-carbon energy production, energy efficiency and water and waste management sectors. Member companies generate more than 50 percent of revenue from products and solutions that help fight climate change or use natural resources efficiently.
