"Ambitious and achievable" is how the White House described its formal emissions reduction pledge--a cut of 26 to 28 percent from 2005 levels by 2025--to the United Nations Framework Convention on Climate Change (UNFCCC) in preparation for negotiation of a binding climate agreement in Paris in December. Opinion about the aptness of the two adjectives was, predictably, mixed.
The U.S. pledge follows on the heels of a U.S. agreement to form a joint task force on climate policy co-operation with Mexico, which has become the first developing nation to formally announce its greenhouse gas emissions reductions ahead of Paris--25 percent by 2030.
The only other countries to meet an informal March 31 deadline to declare formal plans to the UNFCCC for voluntary greenhouse gas emissions cuts--so-called intended nationally determined contributions (INDCs)--were the 28-nation European Union, Switzerland, Norway, and, at the midnight hour, Russia, which said it would cut its emissions by as much as 30 percent from 1990 levels. Gabon submitted its pledge April 1.
The delay in INDC pledges by the vast majority of the world's countries complicates negotiation of a global climate change agreement in Paris in December, Reuters reports. The lag will shrink the time that other countries have to assess whether they will meet others' offers, potentially leading to a "last-minute pile-up" like the one that scuttled climate talks in Copenhagen in 2009.
The U.S. target will entail a substantial ramp-up in reductions. According to the U.S. INDC, "Achieving the 2025 target will require a further emission reduction of 9-11 percent beyond our 2020 target compared to the 2005 baseline and a substantial acceleration of the 2005-2020 annual pace of reduction, to 2.3-2.8 percent per year, or an approximate doubling."
Some of the required efforts have been launched or proposed: increased fuel efficiency standards for vehicles, methane limits for energy production, cuts in federal government emissions, and pollution rules for power plants. The U.S. INDC outlined no plans to meet INDC targets through international carbon trading, but it does suggest that agricultural land use and carbon sinks such as forests will play some role in achieving the targets.
According to the international analysis group Climate Action Tracker, "The U.S. will need to implement additional policies to reach its proposed targets. The planned policies (such as the targets in the Climate Action Plan), if fully implemented, are sufficient to meet the 2020 pledge [a 17 percent reduction in 2005 emissions levels by 2020]. Additional policies will have to be implemented to reach the 2025 pledge."
Arctic Oil Exploration
"To remain globally competitive and to be positioned to provide global leadership and influence in the Arctic, the U.S. should facilitate exploration in the offshore Alaskan Arctic now," the study's authors wrote.
According to the U.S. Energy Information Administration (EIA), the Arctic contains an estimated 13 percent of all oil resources and up to 30 percent of all natural gas resources on the planet (measured in terms undiscovered conventional energy resources). According to the NPC report, if drilling began now in Alaska and continued into 2030 or 2040, Arctic production would help sustain domestic supplies if shale and tight oils decline in the lower 48 states.
The report was released just days before the U.S. Department of the Interior reaffirmed a 2008 auction of Arctic drilling rights, giving Royal Dutch Shell the go-ahead to restart oil exploration in the Alaskan Artic. Despite that news, the National Geographic reports that three factors--permits, safety concerns, and oil reserve amounts--could still slow Arctic drilling.
Report: Renewables Could Help States Meet Clean Power Plan Requirements
The American Wind Energy Association and the Solar Energy Industries Association think renewables have potential. Their new handbook details how states can incorporate renewable energy to comply with the U.S. Environmental Protection Agency's proposed Clean Power Plan, which aims to regulate carbon dioxide emissions from power plants under the Clean Air Act by establishing state-by-state emissions rate goals for affected fossil fuel-fired power plants.
How much and how fast the Clean Power Plan could help renewable energy development depends on a laundry list of technical and policy questions involving the EPA's final rule.
