California ARB releases discussion draft of plan to cut GHG by 40% by 2030

December 02, 2016

The California Air Resources Board (CARB) released its initial draft plan to reduce greenhouse gas emissions by 40% below 1990 levels by 2030—the most ambitious target in North America. The 2030 Target Scoping Plan Discussion Draft builds on the state’s efforts to reach its more immediate goal of reducing greenhouse gas emissions to 1990 levels by 2020 and outlines the most effective ways to reach the new 2030 goal, including continuing California’s Cap-and-Trade program.

In his January 2015 inaugural address, California Governor Jerry Brown identified five key climate change strategy “pillars,” which recognize that several major areas of the California economy will need to reduce their emissions to meet California’s ambitious climate change goals. These five pillars are:

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

November 29, 2016

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO2. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change.

SLCPs include black carbon (soot), methane and hydrofluorocarbons (HFCs)—the fastest-growing source of GHG emissions in California and globally—which are used as refrigerants, aerosol propellants and insulation.

Global Carbon Project: Low growth in global carbon emissions continues for third successive year

November 14, 2016

Global carbon emissions from burning fossil fuels did not grow in 2015 and are projected to rise only slightly in 2016, marking three years of almost no growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project. Decreased use of coal in China is the main reason behind the 3-year slowdown.

The projected rise of only 0.2% for 2016 marks a clear break from the rapid emissions growth of 2.3% per year in the decade to 2013, with just 0.7% growth seen in 2014. The new data shows emissions growth remained below 1% despite GDP growth exceeding 3%. Detailed data were made available in the open-access data journal Earth System Science Data (ESSD). This is the fifth update of the global carbon budget published by ESSD in the living data format.

Oil and Gas Climate Initiative to invest $1B over 10 years in low-emissions tech

November 04, 2016

The Oil and Gas Climate Initiative (OGCI) will invest $1 billion over the next ten years to develop and to accelerate the commercial deployment of innovative low-emissions technologies.

Led by the heads of ten oil and gas companies that aim to lead the industry response to climate change, OGCI member companies—BP, CNPC, Eni, Pemex, Reliance Industries, Repsol, Royal Dutch Shell, Saudi Aramco, Statoil and Total—together represent one fifth of the world’s oil and gas production. The OGCI was established following discussions during the 2014 World Economic Forum Annual Meeting, and was officially launched at the UN Secretary General’s Climate Summit in New York in September 2014.

Lung Association report highlights health and climate costs of petroleum-based transportation and the benefits of shifting to ZEVs

October 27, 2016

A new report produced by the American Lung Association concludes that over-reliance on petroleum-based fuels for transportation costs the 10 ZEV states in the US (California and nine other states that have adopted the California Zero Emission Vehicle (ZEV) program) an estimated $37 billion in health expenses and climate costs every year—with California costs alone hitting $15 billion.

Of that $37 billion, health costs added up to $24 billion in 2015; the $24 billion represents the monetized sum of harmful emissions responsible for an estimated 220,000 work-loss days, more than 109,000 asthma exacerbations, hundreds of thousands of other respiratory impacts, and 2,580 premature deaths.

ICAO agrees to market-based measure to address aviation CO2

October 07, 2016

The UN International Civil Aviation Organization (ICAO) has agreed to recommend adoption of a final Resolution text on a new global market-based measure (GMBM) to control CO2 emissions from international aviation.

ICAO’s Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is designed to complement the basket of mitigation measures the air transport community is already pursuing to reduce CO2 emissions from international aviation. These include technical and operational improvements and advances in the production and use of sustainable alternative fuels for aviation.

Government of Canada announces national plan for carbon pricing

October 04, 2016

The Government of Canada has proposed a pan-Canadian approach to pricing carbon emissions; under the new plan, all Canadian jurisdictions will have carbon pricing in place by 2018.

To accomplish this, Canada will set a benchmark for pricing carbon emissions—set at a level that will help Canada meet its greenhouse gas emission targets. Provinces and territories will have flexibility in deciding how they implement carbon pricing. Jurisdictions can implement: (i) an explicit price-based system (a carbon tax such as British Columbia’s or a carbon levy and performance-based emissions system like in Alberta); or (ii) a cap-and-trade system (e.g. Ontario and Quebec).

California Governor signs new super-pollutants legislation into law; black carbon, fluorinated gases and methane

September 20, 2016

California Governor Edmund G. Brown Jr. signed SB 1383, establishing the nation’s toughest restrictions on super pollutants including black carbon, fluorinated gases and methane. The law is in addition to California’s existing raft of climate legislation.

SB 1383 reduces the emission of super pollutants (also known as short-lived climate pollutants) and promotes renewable gas by requiring a 50% reduction in black carbon and 40% reduction in methane and hydrofluorocarbon from 2013 levels by 2030. Sources of these super pollutants include petroleum-based transportation fuels, agriculture, waste disposal and synthetic gases used in refrigeration, air conditioning and aerosol products.

Technical brief: transportation overtaking electricity generation as the largest source of US CO2 emissions

September 19, 2016

A technical brief by Dr. John DeCicco at the University of Michigan Energy Institute shows that transportation is overtaking electricity generation as the largest source of US CO2.

The average rate at which CO2 is emitted from vehicle tailpipes and other mobile sources has exceeded the rate of CO2 emissions from electric power plants over seven of the past eight months. Although efficiency gains are limiting transportation emissions growth, the gains are not enough to reduce the sector’s CO2 emissions in the face of increased travel and shipping, DeCicco writes. CO2 emissions from the transportation sector increased at an average rate of 1.8% per year over the past four years.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

February 24, 2016

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. Their analysis is published in the Journal of Economic Perspectives.

While renewable energy has made promising gains in just the last few years—the cost of solar dropped by about two-thirds from 2009 to 2014—new drilling and extraction techniques have made fossil fuels cheaper and markedly increased the amount of oil and gas available. In the US alone, oil reserves have expanded 59% between 2000 and 2014, and natural gas reserves have expanded 94% in the same time.
