The most recent UN report on climate change predicts that greenhouse gases already in circulation have committed the planet to a warming of 2.5 degrees. “No matter what we do today to reduce emissions, the planet will still heat up,” says Ramanathan. But, through a quirk that Ramanathan has spent 10 years uncovering, the planet actually manifests only ¼ of the warming it should based on these climate models. Air pollution, specifically brown clouds from burning biomass, Ramanathan has learned, act as a global warming mask, reducing sunlight on the ground. “On the one hand, it has protected us, but also prevented us from seeing the full blast of the greenhouse effect,” he says. “One of the dumbest things we can do is to reduce sunlight,” because it reduces ocean evaporation, which cuts down on rainfall, and shifts weather systems everywhere, shrinking harvests and glaciers.

We are left with “Faustian bargains,” says Ramanathan. If we cut airborne pollutants such as sulfur, the mask will drop, temperatures rise rapidly, and climate tipping elements come into play. Curing one ill causes another. Any plan for “dismantling the experiment we have done with blankets, mirrors and dust must be done as carefully as dismantling a nuclear device.”

“Environment is not a special, short-term project, not a fad or flavor of the month,” says Balta. IBM pursues opportunities in and out of the company, including “making brown green:” reducing waste in its business and industrial processes around the world; designing intelligent networks to improve the efficiency of electrical utility operations; developing systems for mitigating traffic congestion in cities; launching a Big Green innovation business unit; and creating an Eco Patent Commons, enabling users the free and unrestricted use of IBM technologies that help solve environmental challenges.

“We’re trying to find the sweet spot between social, economic and environmental areas that define sustainability, because at the end of the day if any one of those three legs of the stool aren’t available then the model itself falls down.” says Mark Buckley.

British Telecom is tackling three interdependent areas, says Kevin Moss: sustainable economic growth, climate change and creating a more inclusive society.
