U.S. Can Cut Greenhouse Gas Emissions 80 Percent by 2050, Study Says

U.S. Can Cut Greenhouse Gas Emissions 80 Percent by 2050, Study Says

written by Yale Environment 360

The United States can reduce greenhouse gas emissions by 80 percent by 2050, using existing or near-commercial technologies, according to researchers with the Deep Decarbonization Pathways Project.

The study analyzed scenarios with four types of decarbonized electricity: renewable energy, nuclear energy, fossil fuel with carbon capture and storage, and a mixed case. The scenarios achieved reductions of 83 percent below 2005 levels and 80 percent below 1990 levels, according to the study, which was released ahead of next month’s climate talks in Lima, Peru, and negotiations in Paris in December 2015.

The energy efficiency of buildings, transportation, and industry would need to increase through the use of smart materials and energy-efficient designs, and vehicles will need to be fueled with electricity generated from wind, solar, or nuclear, as opposed to coal, the researchers said. They project the net costs would be on the order of 1 percent of gross domestic product per year.

The 80-percent reduction by 2050 is a long-standing goal of the Obama administration, in line with the global commitment to limit global warming to less than 2 degrees Celsius. “One important conclusion is that investment opportunities in clean technologies will arise during the natural rollover and replacement of infrastructure,” said lead author Jim Williams. “The plan calls for non-disruptive, sustained infrastructure transitions that can deeply decarbonize the U.S. by 2050, and enhance its competitive position in the process.”

China – Saving Energy or Saving Face?

written by Walter Wang

China, which last year walked away from COP 15 without agreeing to anything, now wants to hold its own climate talks.

The talks, scheduled for October, according to the UN’s top environmental official, Achim Steiner, will take place in the northern Chinese port of Tianjin, northwest of Beijing.

Government officials around the industrialized world are hoping that the Tianjin talks will pave the way for a new, binding, climate change treaty after COP 15’s

Grim Outlook for Emissions As Climate Talks Limp Forward

written by Yale Environment 360

In the wake of the failed Copenhagen summit, prospects for cutting global CO2 emissions are worse than they’ve been in years. With talk of mandated cuts now fading and with countries exploiting loopholes, the world appears headed toward a flawed agreement based not on science but on politics.

Those who thought the failed Copenhagen climate talks last December were a diplomatic nadir, from which only recovery was possible, are in for a shock.
