National Temperature Data, Collected Since 1895, Shows 2012 Will Shatter The Previous Record For The

The American Lung Association released its 2012 "State of the Air" report. Among their findings, they report that the air quality in many places has improved, but that over 127 million people—41 percent of the U.S.—still suffer pollution levels that are too often dangerous to breathe. The report includes this graph from EPA, showing that emissions of the six common air pollutants have fallen 59% since 1990 as a result of Clean Air Act regulations. These reductions have occurred even as population, energy consumption, vehicle miles traveled and GDP have increased, debunking the myth that environmental regulations hurt economic growth.

*The "six common pollutants" are fine particulate matter (PM2.5 and PM10), sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), carbon monoxide (CO), and lead.

Carbon dioxide emissions in the UK are falling. CO2 emission fell 5.8% in 2016 from the previous year. Current emissions represent a 36% reduction from 1990 levels, and are at their lowest level since 1894 (outside the 1920s general strikes).

Why? The decline of coal. Coal use in the UK has declined steadily from its peak in 1956, and has experienced a dramatic decline since 2012. Coal use in 2016 dropped 52% from 2015.

The reduction in coal use is a result of multiple factors. The biggest is the expanded use of natural gas and renewables displacing coal. Other factors include an overall reduction in energy demand, the closing of Redcar Steelworks in 2015, and the UK’s carbon tax.

California's climate change law (AB 32), which puts a price on carbon emissions and creates a cap-and-trade system to reduce greenhouse gas emissions, is yielding substantial reductions in emissions from oil refineries. These refineries are a major source of carbon emissions, along with a host of other toxic chemicals like ammonia, lead, benzene, mercury and acid gases.

Data from the California Air Resources Board shows that 11 refineries substantially reduced emissions between 2010 and 2011, in addition to cuts in the release of other toxic pollutants. Evidence shows that these reductions not a result of cuts in production, but to refineries investing in and upgrading equipment in response to AB 32. An example is Valero’s refinery in Benicia, CA, which decreased covered emissions by over 95,000 metric tons, while also cutting ammonia emissions by 98%, sulfuric acid by 84%, and benzene by 49%, through the installation of a new flue gas scrubber.

When thinking of ways to make renewable energy cost-competitive with fossil fuels, an important consideration are the market distortions caused by substantial government subsidies to fossil fuels versus subsidies to renewable energy. De-carbonizing the global energy sector will require removing subsidies for fossil fuels.

Based on a survey of 144 climate change economists performed by the Institute for Policy Integrity at the New York University School of Law, response to: "Placing a “price on carbon” through a tax or cap‐and‐trade system will increase incentives for energy efficiency and the development of lower carbon energy production."

Other interesting results:

84% agreed or strongly agreed that “the environmental effects of greenhouse gas emissions... create significant risks to important sectors of the United States and global economies.”

91.6% preferred or strongly preferred “market‐based mechanisms, such as a carbon tax or cap‐and‐trade system” over command‐and‐control regulation to reduce greenhouse gas emissions.
