Investing in a Warmer Future

Bloomberg Businessweek explores how firms are adapting to a future climate:

Investing in climate change used to mean putting money into efforts to stop global warming. Morgan Stanley, Goldman Sachs, and other firms took stakes in wind farms and tidal-energy projects, and set up carbon-trading desks. The appeal of cleantech has dimmed as efforts to curb greenhouse gas emissions have faltered: Venture capital and private equity investments fell 34 percent last year, to $5.8 billion, according to Bloomberg New Energy Finance.

Now some investors are taking another approach. Working under the assumption that climate change is inevitable, they’re investing in businesses that will profit as the planet gets hotter. (The World Bank says the earth could warm by 4C by the end of the century.) Their strategies include buying water treatment companies, brokering deals for Australian farmland, and backing a startup that has engineered a mosquito to fight dengue, a disease that’s spreading as the mercury climbs.

Piet Dircke of the Dutch engineering and flood-prevention firm Arcadis says he was besieged with calls after Hurricane Sandy: “The climate is changing. Sea level is rising. That’s quite obvious. At the same time, the cities that are close to the waterline continue to grow and have more money and need for protection. It’s almost a natural growth market.”
