climate change

As evidence of climate change mounts, President Obama has made it clear that tackling this issue will be a priority in his second term. Yet, as weeks go by, the administration has been slow to clarify its strategy. With each passing day, it becomes harder and more expensive to rein in greenhouse gas emissions.

Meanwhile, other global powers are moving forward--and many of them carry valuable lessons which American policymakers can look to. The most successful countries are showing national leadership, strong and consistent policies, and commitment to clean energy.

Where, then, are signs of progress on clean energy?

Germany’s Energiewende: Leading the Way

High on the list is Germany, whose ambitious energy transformation strategy--or “Energiewende”--aims to reduce greenhouse gases by 80 to 95 percent by 2050, compared to 1990 levels. This will be achieved by enhancing energy efficiency, reducing primary energy consumption by 50 percent, and ramping up renewable energy to at least 80 percent of electricity consumption in the same time-frame.

Delegates at the April UNFCCC intersessional in Bonn, Germany made some encouraging progress. As negotiators gather again this week, it’s important that they build on this progress and take action on two key topics: raising ambition, and establishing core elements of the 2015 international climate action agreement.

Indeed, there’s an even greater sense of urgency since delegates met for the April intersessional. The world crossed a perilous and alarming threshold, with atmospheric carbon dioxide levels exceeding 400 ppm, a level that has not been experienced in at least 800,000 years and possibly not for millions of years. Plus, this may be the last intersessional before COP 19 in Warsaw in November. Negotiators must move forward on raising ambition and establishing the 2015 Agreement if COP 19 is to have a successful outcome.

Raising Ambition Now

The need for countries to make more ambitious emissions-reduction commitments remains self-evident—even more so, now that the world has exceeded 400 ppm of atmospheric carbon dioxide. In Bonn, negotiators are set to focus on the transformation of the energy system.

Global emissions just crossed 400 parts per million, an ominous threshold for the climate. Despite this marker, there are signs of new life for international climate action, including during the recent United Nation’s climate meeting in Bonn, Germany.

It’s become abundantly clear that in order for the world to reach an international climate agreement by 2015, the usual approach isn’t going to work. World leaders need to find common ground and work toward solutions. They need to engage their citizens and infuse new passion into the issue. Climate change is not just an environmental issue – it is one of the great moral tests of our times.

In Chile, we know all too well the impacts of climate change, marked in particular by more frequent droughts and increasing water scarcity. This affects people and our economy across sectors, from agriculture and manufacturing to mining and energy. Sadly, the people most affected by climate change are the poorest and most vulnerable members of society.

In the face of this challenge, we need a new narrative that engages people and presents the issue as a social and economic story rather than as just an environmental one. We need to create a world in which people prosper but without increasing pollution. This is not a distant dream, but a real possibility.

Scientific understanding of the chemicals that contribute to climate change is constantly improving. So, too, is the Greenhouse Gas Protocol (GHGP), as we work to keep abreast of such advances and ensure that they are reflected in our tools and standards.

One recent example concerns the greenhouse gas (GHG) nitrogen trifluoride (NF3), a chemical that is released in some high-tech industries, including in the manufacture of many electronics. The GHG Protocol now requires NF3 to be included in GHG inventories under the Corporate Standard, Value Chain (Scope 3) Standard, and Product Standard. A new GHGP Amendment updates the existing requirements.

How does this update affect my organization?

NF3 is used in a relatively small number of industrial processes. It is primarily produced in the manufacture of semiconductors and LCD (Liquid Crystal Display) panels, and certain types of solar panels and chemical lasers. To the extent that these processes occur in your company’s direct operations or value chain, they may need to be reflected in future inventories to ensure conformance with GHG Protocol standards.

The U.S. Department of Energy made a big announcement late last week, green lighting the country’s second liquefied natural gas (LNG) export project. Many argue that natural gas exports will bring economic and geopolitical benefits for the United States--with Japanese and French companies coming on board as key partners in the proposed export station.

Indeed, natural gas can contribute to a lower-emissions trajectory--but only if it’s done right. With effective policies and standards in place, natural gas can help displace coal while complementing lower-carbon, renewable energy sources. But without these protections, U.S. LNG exports will likely lead to an increase in domestic greenhouse gas (GHG) emissions and, as discussed below, may have a negative effect on global climate change.

The question becomes whether government agencies and businesses will take the necessary steps to limit the emissions risks associated with natural gas, including through LNG exports.

Germany is in the midst of an unprecedented clean energy revolution. Thanks to the “Energiewende,” a strategy to revamp the national energy system, Germany aims to reduce its overall energy consumption and move to 80 percent renewable energy by 2050. The country has already made considerable progress toward achieving this ambitious goal.

In fact, other countries like the United States can learn a lot from the German clean energy experience. That’s why WRI is hosting a German energy speaking tour in the United States this week, May 13th-17th. Rainer Baake, a leading energy policy expert and key architect behind the Energiewende, and WRI energy experts will travel to select U.S. cities to share lessons, challenges, and insights from the German clean energy transformation. They will be joined by Dr. Wolfgang Rohe and Dr. Lars Grotewold from Stiftung Mercator.

The German Fast-Start Finance Contribution

Germany’s fast-start finance (FSF) contribution reflects a significant focus on financing climate action in developing countries. Germany exceeded its self-defined FSF pledge for the 2010-2012 FSF period, providing a total of EUR 1.29 billion, and also pledged to deliver EUR 1.8 billion in 2013...

U.S. natural gas production is booming. According to the Energy Information Administration (EIA), production grew by 23 percent from 2007 to 2012. Now—with production projected to continue growing in the decades ahead—U.S. lawmakers and companies are considering exporting this resource internationally. But what are the climate implications of doing so?

This is a topic I sought to address in my testimony yesterday before the U.S. House of Representatives Energy and Commerce Subcommittee on Energy and Power. The hearing, “U.S. Energy Abundance: Exports and the Changing Global Energy Landscape,” examined both the opportunities and risks presented by exporting liquefied natural gas (LNG). I sought to emphasize a number of points that are often overlooked in this discussion; in particular, fugitive methane emissions and cost-effective options for reducing them.

Environmental Impacts of Natural Gas Production

While burning natural gas releases half the amount of carbon dioxide as coal, producing the fuel comes with considerable environmental risks (see: here, here, and here). We’re already seeing these risks play out domestically. In addition to habitat disruption and impacts on local air and water quality, one of the most significant implications of natural gas production is fugitive methane emissions.
