What Does a Climate Deal Mean for the World?

Times staff, Dec. 12, 2015

A group of 195 nations reached a landmark climate agreement on Saturday. Here is what it means for the planet, business, politics and other areas.

The Planet

The planet is under threat from human emissions, and the Paris climate deal is, at best, a first step toward fixing the problem. Ice sheets are starting to melt, coastlines are flooding from rising seas, and some types of extreme weather are growing worse. Yet some of the consequences of an overheated planet might be avoided, or at least slowed, if the climate deal succeeds in reducing emissions. At the least, by requiring regular reviews, the deal lays a foundation for stronger action in the future. – JUSTIN GILLIS

Global Politics

Strange bedfellows emerged during the Paris negotiations, with industrial powerhouses such as the European Union joining with Pacific island nations and former adversaries, like China and the United States, swapping brinksmanship for bonds over joint action to cut fossil fuel emissions. The pact could leave more geopolitical shifts in its wake. It could further move the energy balance of power away from the developing world toward the industrialized countries, boost the economy in technology economies like the United States and Japan as they develop solutions for the generation and distribution of renewable energy, and create economic stars out of relatively poor countries with an abundance of sun and wind for renewable energy. On the other hand, major oil producers like Russia and Saudi Arabia, already weakened by the slide in the price of oil, could shed some power. – MELISSA EDDY

American Politics

The Paris accord is a triumph for President Obama and Secretary of
State John Kerry, who both lobbied hard for it, but it has outraged
many Republicans who are skeptical of the extent of human-caused
climate change and believe the deal favors environmental ideology over economic reality. The environment has not typically played a major role in voters’ choices, and the issue will most likely be overshadowed in the current election cycle by fears of terrorism, though the drought in California and severe weather in many parts of the country have raised concerns for many Americans. The Republican-controlled Congress can do little to stop the deal, which is not considered a treaty under United States law, though Congress would need to sign off on any new money to help other countries adapt to climate change — an important aspect of the American commitment to the accord. – SEWELL CHAN

Business

The ambitious targets included in Saturday’s deal for limiting the rise in global temperatures may help companies involved in renewable energy and energy efficiency by expanding their markets. Setting a high bar may also make the energy industry attractive for innovators and venture capitalists, increasing the chances of sweeping shifts in what has been a conservative business. The agreement may make life difficult for some of the incumbent companies like electric utilities and coal producers, whose product emits high levels of carbon dioxide. – STANLEY REED

The average American most likely will not feel an immediate effect from the Paris deal. There will be greater emphasis on more efficient electrical products, homes and vehicles. Jobs could be created through the construction of a new energy infrastructure, the maintenance of solar fields and the development of new transportation systems that move away from dependence on the gas pump, as Secretary of State John Kerry has said. Or, as Republicans warn, Americans could see a loss in jobs and American economic competitiveness, as developing economies with less stringent targets are allowed to grow at American’s expense. The deal’s intended long-term effect: avoiding the catastrophic effects of climate change and leaving behind a healthier planet. – MELISSA EDDY

 

Energy-related CO2 emissions decreased in nearly every state from 2005 to 2013

Energy-related carbon dioxide emissions decreased in nearly every state from 2005 to 2013

The United States has a diverse energy landscape that is reflected in differences in state-level emissions profiles. Since 2005, energy-related carbon dioxide (CO2) emissions fell in 48 states (including the District of Columbia) and rose in 3 states. EIA’s latest analysis of state-level energy-related CO2 emissions includes data in both absolute and per capita terms, including details by fuel and by sector.

This analysis measures emissions released at the location where fossil fuels are consumed. Therefore, to the extent that fuels are used in one state to generate electricity that is consumed in another state, emissions are attributed to the former rather than the latter. An analysis attributing emissions to the consumption of electricity, rather than to the production of electricity, would yield different results.

The 10 states with the highest levels of energy-related CO2 emissions in 2013 accounted for half of the U.S. total. These 10 states also have large populations and account for slightly more than half (53%) of the nation’s total population. California was the second-highest emitter in absolute terms (353 million metric tons of carbon dioxide, or MMmt CO2), behind only Texas (641 MMmt CO2). But California was also the fourth-lowest emitter on a per capita basis, behind the District of Columbia, New York, and Vermont. Relatively small states such as Wyoming and North Dakota had much higher levels of per capita emissions in 2013, nearly seven times and five times the national average, respectively.

Energy-related CO2 emissions come from coal, petroleum, and natural gas consumed within a state to produce electricity (38% of U.S. total), to transport goods or people (33%), to operate industrial processes (18%), or to directly fuel equipment in residential and commercial buildings (10%). The consumption levels by fuel and by sector vary considerably by state. For example, coal consumption accounted for 78% of energy-related CO2 emissions in West Virginia in 2013, while coal only accounted for 1% of emissions in California.

Consumption of petroleum accounted for more than 90% of energy-related CO2 emissions in two states, Hawaii and Vermont, but for different reasons. In both states, emissions from the transportation sector accounted for more than 50% of energy-related emissions. In Vermont, the nonelectric (or direct) residential share of total emissions was 23%, mostly from petroleum-based fuels such as heating oil used to fuel furnaces and water heaters. Vermont’s electric power sector share of emissions from petroleum was only 0.2%, as very little of the state’s electricity in 2013 was generated from petroleum or any other fossil fuels. Hawaii, on the other hand, has very little direct use of petroleum for residential heating but much higher use of petroleum for power generation.

More information about each state’s energy-related CO2 emissions is available in EIA’s report, Energy-Related Carbon Dioxide Emissions at the State Level, 2000-13.

U.S. Energy-Related Carbon Dioxide Emissions, 2014

Release Date: November 23, 2015   |  Next Release Date: October 2016   |    full report

U.S. Energy-related carbon dioxide emissions increased 0.9% in 2014

  • Energy-related carbon dioxide (CO2) emissions increased by 50 million metric tons (MMmt), from 5,355 MMmt in 2013 to 5,406 MMmt in 2014.
  • The increase in 2014 was influenced by the following factors:
    • Real gross domestic product (GDP) grew by 2.4%;
    • The carbon intensity of the energy supply (CO2/Btu) declined by 0.3%; and
    • Energy intensity (British thermal units[Btu]/GDP) declined by 1.2%.
  • Therefore, with GDP growth of 2.4% and the overall carbon intensity of the economy (CO2/GDP) declining by about 1.5%, energy-related CO2 grew 0.9%.

Davis Enterprise Editorial: Benicia washes its hands of us

Our view: Benicia washes its hands of us

By Our View | November 15, 2015

The issue: Bay Area city can’t see past its own back yard on refinery project

The city of Benicia — the only entity capable of exerting any control over the crude-oil shipments set to arrive at a planned expansion of a Valero oil terminal — has shown in a draft environmental impact report that any impact the terminal has on communities farther up the train tracks is none of its business.

THE PROPOSED project would allow Valero to transport crude oil to its Benicia refinery on two 50-car freight trains daily on Union Pacific tracks that come right through Davis, Dixon, Fairfield and Suisun City on their way to Benicia. The rail shipments would replace up to 70,000 barrels per day of crude oil currently transported to the refinery by ship, according to city documents.

The original draft EIR, released in 2014, didn’t adequately address safety and environmental concerns. Local governments — including the city of Davis, Yolo County and the Sacramento Area Council of Governments — weighed in on the draft, urging Benicia to take a second look.

Benicia withdrew the draft and went back to work, and the new document acknowledges the risks of pollution, noise and, oh yes, catastrophic explosions from oil trains, the likes of which leveled Lac-Mégantic, Quebec, in 2013.

Disappointingly, having recognized the issues involved, the report simply says there’s no way to mitigate them and recommends moving ahead. With a bureaucratic shrug of the shoulders, the concerns of communities from Roseville to Suisun City are dismissed.

NATURALLY, SACOG disagrees, and so do we. While it’s true that there’s not a lot Benicia can do itself to mitigate the impact of its project, it can force Valero to do something about it.

SACOG urges a raft of measures that are within Valero’s control: advanced notification to local emergency personnel of all shipments, limits on storage of crude-oil tanks in urban areas, funding to train emergency responders, cars with electronically controlled pneumatic brakes, money for rail-safety improvements, implementation of Positive Train Control protocols and, most importantly, a prohibition on shipments of unstabilized crude oil that hasn’t been stripped of the volatile elements that made Lac-Mégantic and other derailments so catastrophic.

Due to federal laws, cities along the railway lines have no ability to control what goes through. Only Benicia, now, while the project is still on the drawing board, has the authority to set reasonable limits and conditions on a project that puts millions of people along the railroad in harm’s way.

We urge the Benicia City Council to use its discretionary authority in this matter to protect those of us who have no say in the process.
