U.S. Pledges Far-Reaching Climate Cooperation with China and Japan: the Possibility of Progress Beyond Formal UN Climate Talks

John Kerry signs pledge for climate cooperation with Japan and China. International progress is possible outside the UN climate negotiating processJohn Kerry made climate change a centerpiece of his first Asia tour as Secretary of State over the weekend, signing agreements with both Japan and China for cooperation in implementing practical measures for reducing greenhouse gas emissions. The agreements with both nations stressed practical measures available for reducing greenhouse gases, largely ignoring the contentious United Nations process for hammering out an international climate change agreement that has to date fallen far short of its goal.

China and the United States represent the two largest carbon emitting nations and analysts have  said the agreement between the two nations could mark a significant move forward and put China and the US at the “center of serious clean energy work.”

“China and the United States represent the world’s two biggest economies, we represent the world’s two largest consumers of energy, and we represent the two largest emitters of global greenhouse gases,” said Kerry in a statement. “So if any two nations come to this table with an imperative for action, it is us.

What the United States and China decide to do with respect to this, whatever energy initiative we embrace together … the two largest economies in the world will send a signal to the world about how serious we are about this,” he said.

Head Start Towards 2020: California Reduces CO2 Emissions for Third Year in a Row

Comparison of California carbon emissions by sector from 2008-2011California’s CO2 emissions fell in 2011 for the third straight year, putting the state in a good position for meeting its target of reducing carbon emissions to 1990 levels by 2020, according to the California Air Resources Board (CARP) and as mandated by California AB32 (the Global Warming Solutions Act of 2006). Since businesses began reporting data in 2008, emissions have steadily declined from 133,4 million tons to 111million tons of carbon dioxide equivalent, shedding a full 22 percent in 2011.

Electricity production, once the leading sector for CO2 emissions in the state, made the biggest inroad towards reduction targets by cutting emissions 17.5 million ton between since 2008. Emissions from electricity generation was 34.9 million tons in 2011. Read More→

EarthTalk: What to Expect from the COP15 Climate Conference in Copenhagen

International organizers, delegates and others attending the upcoming COP15 climate conference in Copenhagen, Denmark are hoping for the establishment of an ambitious, legally binding global emissions reduction agreement to take effect beginning in 2012. That is when initial commitments made under the Kyoto Protocol, an earlier international climate treaty that the U.S. refused to join, expire

Dear EarthTalk: What do organizers hope to accomplish at the upcoming (December 7-18, 2009) United Nations Climate Change Conference being held in Copenhagen? – F. Rojas, Oakland, CA

The upcoming COP15 meeting in Denmark—so named because it is the 15th such international gathering of the Conference of the Parties (COP) under the United Nations Framework Convention on Climate Change—is the world’s next big chance to take decisive multi-lateral action on reducing greenhouse gas emissions substantially enough to ward off cataclysmic climate change.

Negotiators from all over the globe hope to come to terms on a binding agreement regarding emissions reductions that both developed and developing nations can agree to. The stakes are high: This conference represents the final step in negotiations years in the making—and the results could chart a course toward success or failure in human efforts to control the carbon beast we set free in the industrial revolution.

Officially, the stated goal of COP15, according to United Nations organizers, is “to stabilize the amount of greenhouse gases in the atmosphere at a level that prevents dangerous man-made climate changes.” They add that “this stabilization must occur in such a way as to give the ecosystems the opportunity to adapt naturally” without compromising food safety or hindering sustainable social and economic development around the world. Organizers, delegates and a wide range of other participants—some 10,000 people are expected to attend—are still holding out hope for the establishment of an ambitious, legally binding global emissions reduction agreement to take effect beginning in 2012. That is when initial commitments made under the Kyoto Protocol, an earlier international climate treaty that the U.S. refused to join, expire.

One sticking point is whether or not the Obama administration will risk agreeing to major emissions reductions without the prior consent of Congress. The most promising U.S. climate legislation, the so-called Kerry-Boxer Bill, is currently under consideration in the Senate but likely won’t be voted on until February 2010 or later; traditionally the American government likes to iron out its policy legislatively at home before agreeing to international commitments. But bi-partisan backers of the bill in the Senate say they can agree on terms now that will be acceptable to enough to their colleagues for later passage, enabling American negotiators at Copenhagen to have some guidelines at the COP15 bargaining table.

China and much of the developing world would like to see industrialized countries cut their greenhouse gas emissions 40 percent below 1990 levels by 2020, but analysts say such drastic cuts are unlikely to fly with U.S. politicians. Climate champion Al Gore is urging COP15 delegates to create a binding legal framework where commitments can be ratcheted up with time as governments begin to realize the benefits of switching to larger amounts of renewable energy and participating in the development of green technology.

Beyond the big question of U.S. participation, COP15 negotiators will be trying hard to forge a consensus on a wide range of related issues, including: what year should be set as the baseline against which specific reduction targets will be measured; the duration of the emissions reduction commitment period; whether or not to call for curbs on deforestation, especially in developing countries’ tropical rainforests; and whether or not to tighten rules governing the methods used to reduce emissions.

Physicists Urge Energy Efficiency as Top Priority

American Physical Society urges energy efficiency as a solution for the energy crisis

American Physical Society urges energy efficiency as a solution for the energy crisis

“The Opportunities are Huge and the Costs Are Small”

A report released today by the American Physical Society urges the United States to prioritize energy efficiency in cars and buildings as a means of addressing the nation’s dependence on foreign oil and reducing greenhouse gas emissions.

The report from the 46,000 member organization characterizes the energy crisis as the worst in U.S. history and that the physics and chemistry behind the human causes of global warming is “well understood and beyond dispute”.

While the mantra and imagined solution to the energy crises from some remains summarized in the all-too-familiar phrase drill now, the report concludes that increasing energy efficiency is “comparable to discovering a hidden U.S. energy reserve”. One that is relatively easy and cheap to tap – “far easier than tapping new supplies of any kind”. Yet, the country is “slow to catch on” in fully utilizing the potential of energy efficiency, a strategy that would also reduce costs without sacrificing “comfort and convenience”.

Energy that you don’t use is free. It’s not imported and it doesn’t emit any greenhouse gases. Most of the things we recommend don’t cost anything to the economy. The economy will save money”, says Burton Richter, who chaired the study panel and is the 1976 winner of the Nobel Peace prize in physics, “The bottom line is that the quickest way to do something about America’s use of energy is through energy efficiency”.

The two key areas where efficiency can derive the most benefit are transportation and buildings, which together consume two-thirds of our energy. Many of the short-term strategies to improve efficiency will cost little to implement, but the report urges the federal government to increase spending on research and development of next-generation building technologies as well as for development of batteries for hybrid vehicles, plug-in hybrids, and battery electric vehicles.

Following are key points from the report:

Transportation

  • Technologies are available to safely move beyond the 35 mile per gallon Corporate Average Fuel Economy (CAFE) standard mandated by law by the year 2020. The federal government should establish policies to ensure that new light-duty vehicles average 50 mpg or more by 2030.
  • Plug-in hybrids require more efficient and more durable batteries able to withstand deep discharges that are not yet in commercial large-scale production. Given the technical difficulties, plug-in hybrids will not replace the standard American car in the near future.
  • Hydrogen fuel cell vehicles have the potential to eliminate gasoline usage, but they also require scientific breakthroughs, including advances in fuel cells, catalysts and on-board hydrogen storage systems

Buildings

  • Energy use by buildings could be no higher in 2030 than it is today if technologies that are available or in the pipeline are installed in a cost-effective manner.
  • Widespread, cost-effective construction of residential zero energy buildings (ZEB)—buildings that use no net energy—is feasible by 2020, except in hot, humid climates.
  • Widespread, cost-effective construction of ZEB commercial buildings by 2030—a current goal in law and of many groups—will not be possible without an intensified federal program of research, development and demonstration.
  • Current green building rating systems such as Leadership in Energy and Environmental Design (LEED) do not appear to give sufficient weight to energy efficiency

The American people need leadership from the Congress and the next president on this issue,” says Richter, “Both Senators McCain and Obama have outlined plans for improving energy efficiency and the important role new technologies will play in our energy future. The next leader of the United States will have an opportunity to be the first in history to lay the necessary groundwork to reduce energy use among Americans”.

Global Warming (excerpt from report)

The physics and chemistry of the greenhouse-gas effect are well understood and beyond dispute. Science has also achieved an overwhelming consensus that the increase in greenhouse gases is largely of human origin, tracing back to the Industrial Revolution and accelerating in recent years, as carbon dioxide and methane – the products of fossil fuel use – have entered the atmosphere in increasing quantities. Modeling the climate has proven to be a complex scientific task. But although the models are far from perfect, many of their predictions are so alarming that conservative, risk-averse policymaking requires that they be considered with extraordinary gravity.”
