Will Paris Conference Finally
Achieve Real Action on Climate?

by fred pearce
The emission pledges from the world’s nations still fall short of the goal for limiting global warming. But as negotiators convene in Paris this week, there is cautious optimism that a significant international agreement on climate can be reached.

For Storing Electricity, Utilities
Are Turning to Pumped Hydro

by john roach
High-tech batteries may be garnering the headlines. But utilities from Spain to China are increasingly relying on pumped storage hydroelectricity – first used in the 1890s – to overcome the intermittent nature of wind and solar power.

30 Nov 2015: Paris COP21 — Obama, Xi Vow to
Lead In Climate Fight as Paris Talks Open

Joining leaders from 150 nations in Paris, President Barack Obama acknowledged the U.S.’s special responsibility as the major historical emitter

of greenhouse gases and vowed that the U.S. would take a leading role in fighting climate change, which he called the central challenge of the 21st century. “The United States of America not only recognizes our role in creating this problem, we embrace our responsibility to do something about it,” Obama said at the opening of United Nations climate talks. He vowed that the U.S. and other developed nations would provide aid for renewable energy development and climate adaptation to developing nations, which he said had “contributed little to climate change but will be the first to feel its most destructive effects.” Chinese President Xi Jinping said that his country would meet its goal of hitting peak emissions by 2030, with steady declines thereafter.


Interview: Why Brazil’s Pledges On
Carbon Emissions Are Not Enough

In recent years, Brazil has been widely praised for reducing deforestation in the Amazon by 75 percent from 2005 to 2014.
Maria Fernanda Gebara
Maria Fernanda Gebara
But with United Nations climate talks set to begin next week in Paris, analysts are taking a closer look at Brazil’s pledges to cut deforestation and greenhouse gas emissions, with some saying there is less there than meets the eye. One of the more outspoken critics of the country’s CO2-reduction policies is Brazilian political scientist Maria Fernanda Gebara. In an interview with Yale Environment 360, Gebara, a research associate in the Department for International Development at the London School of Economics, says Brazil’s policies will do little more than stabilize emissions for the next 15 years, will fail to clamp down on illegal logging, and will continue the nation’s dismal record of developing solar and wind power.

25 Nov 2015: Airlines Could Halve Emissions
By 2050 by Making Cost-Saving Changes

Airlines could cut their greenhouse gas emissions in half over the next 35 years by making changes that would actually

save them money, according to research published in the journal Nature Climate Change. Researchers developed a list of 14 strategies, all based on current technologies, that airlines could pursue to cut emissions, which account for roughly 2 to 3 percent of the total carbon dioxide added to the atmosphere each year. For example, one recommendation is to keep planes at the gate until takeoff rather than making them idle on the runway, or to use fewer engines — perhaps even electric engines — when taxiing. Emissions could also be cut significantly by reducing aircraft weight, the researchers say, such as by lowering the amount of extra fuel carried or replacing seats and brakes with ones made from lighter materials. Updating flight paths to more direct routes, adjusting altitude and speed to avoid drag-inducing turbulence, and retiring older planes would also cut costs and emissions.

Could Help Turn the Tide on Climate

fiber technology that extracts CO2 from the air and turns it into cars and other industrial products. Concrete manufacturing that is carbon-negative rather than the energy-guzzling Portland cement used today. These and other ideas represent what Australian scientist Tim Flannery calls “third way technologies” — safe methods to reduce carbon dioxide levels that could be adopted in concert with large-scale reductions in greenhouse gas emissions. In an interview with Yale Environment 360, Flannery explains that unlike risky geo-engineering schemes, these approaches “strengthen Earth’s own self-regulatory system by drawing CO2 out of the atmosphere in ways the planet naturally does already.”

24 Nov 2015: Transportation and Buildings
Drove Rise in U.S. Energy Emissions Last Year

Energy-related carbon dioxide emissions in the U.S. rose last year by 1 percent, marking the second consecutive year of

Low fuel prices drove higher vehicle emissions.
increased energy emissions despite advances in efficiency and growing use of less carbon-intensive fuels, such as natural gas. The transportation sector and residential and commercial buildings largely drove the increase, the U.S. Energy Information Administration reports. Lower fuel prices and an improving economy led to more consumption of gasoline and other fuels, the EIA says, which more than offset gains in vehicle fuel economy. Emissions from commercial and residential buildings also rose last year. While residential energy use is mainly driven by weather on a year-to-year basis — the first quarter of 2014 was particularly cold in many regions — both weather and economic gains led to more energy consumption in commercial buildings, the report says. Looking at energy emissions by another measure, the U.S. made better progress, as CO2 emissions per unit of gross domestic product declined.


23 Nov 2015: In Major Shift, Alberta
Adopts New Plans to Fight Climate Change

In a sharp reversal from the previous government, Alberta’s recently elected premier has announced a host of new climate measures, including a tax on carbon, the phase-out of coal emissions by 2030, a transition to

renewable energy sources, and CO2 emissions limits on the province’s massive tar sands industry. Premier Rachel Notley said Sunday that the province will adopt an economy-wide carbon tax of 20 Canadian dollars in 2017, increasing to 30 dollars in 2018. She vowed that two-thirds of the electricity now produced by coal-fired power plants will be replaced with renewable energy. And she said Alberta will impose a carbon emissions limit on the oil sands industry of 100 megatons; the industry currently generates 70 megatons of carbon annually. “This is the day we step up, at long last, to one of the world’s biggest problems: the pollution that is causing climate change," Notley said.
