Natural gas produces lower emissions than any other fossil fuel.– Natural gas combustion produces an average of 60 kgCO2/MMBtu, while burning

coal produces 92-102 kgCO2/MMBtu.

Gas-fired power generation produces far lower emissions.– The most advanced combined cycle gas turbine (CCGT) power plants can produce

less than 350 kgCO2 per MWh—half the amount produced by the most efficient coal-fired power plants.

Natural Gas Promotes Sustainable Transport

Natural gas vehicles can promote air quality. Delhi’s switch to compressed natural gas (CNG) vehicles for public transport helped to reduce carbon monoxide and particulate levels.

Over the past decade, the number of natural gas vehicles worldwide has grown from 1.3 million to 11.4 million, and the number of countries using CNG in transportation has doubled.

Although the vast majority of CNG vehicles are passenger cars, CNG could play a larger role in long-haul trucking and transportation in the future.

Natural Gas Does Not Require Subsidies

Unlike heavily subsidized renewable technologies, natural gas use allows countries to affordably reduce their carbon emissions.

Government subsidies and direct spending accounted for about one-third of the $145 billion invested in clean energy projects worldwide in 2009.¹

In the United States, for example, subsidies provided for energy include:– Renewable Energy Production Tax Credit– Nuclear Energy Production Tax Credit– Energy Investment Tax Credit– Loan Guarantees– Clean Coal Technologies Investment Tax Credit– Local and State Incentives

Natural gas, unlike most renewable technologies, does not require government subsidies to remain competitive—allowing countries to achieve emissions

targets while avoiding market distortions.

Natural Gas is Available Now

In contrast to renewable technologies that in some cases will require decades of research and innovation, the environmental benefits of gas can be realized today.

Using gas to displace coal in power generation offers an immediate opportunity to reduce emissions. In the United States, coal accounts for 80% of CO2 emissions from the power sector and 33% of all US CO2 emissions—and doubling the utilization rates at existing gas-fired plants could displace enough coal to reduce coal-related emissions by 20%.¹

The Intergovernmental Panel on Climate Change (IPCC) has noted that as the fossil fuel with the lowest CO2 intensity, natural gas offers an immediate opportunity to reduce emissions.

Natural Gas is Flexible

Gas can serve as a flexible partner in power generation for intermittent technologies like solar and wind, facilitating the phase-in of renewables.

Wind power, for example, typically has a very low capacity factor—in most cases between 20% and 40%—meaning that those energy sources are effectively idle for 60% to 80% of the time.

Because gas is a load-following resource—gas turbines can be adjusted upward and downward fairly rapidly according to load changes—gas is essential to complement the growth in variable energy sources.

Natural Gas is Efficient

Modern gas-fired power plants are 40% more efficient than coal-fired plants. Combined cycle gas turbine (CCGT) plants can achieve thermal efficiency rates of 55-60%, compared with thermal efficiency of 42% for coal and 33% for nuclear.

CCGT plants—producing both electricity and heat—have boosted overall plant efficiencies considerably, reducing GHG emissions per unit of energy generated.

Natural gas transmission, distribution and consumer use have become more efficient—and sound energy policies can lead to further improvements. In a 2008 survey of natural gas utilities in 33 US states with energy efficiency programs, reported energy savings averaged 9% for residential users and 7% for all users.¹

Natural Gas Saves Time

Gas-fired power plants require less construction time than either coal-fired plants or nuclear facilities.

A typical gas-fired power plant can take only two years to construct—less than half the lead time required to build a coal-fired plant, and less than one-third the time required to construct a nuclear plant.

This shorter construction time makes it easier for firms to make efficient investment decisions.

Nuclear plants in particular have been subject to extreme cost overruns and larger-than-expected decommissioning costs. The lengthy construction time (often more than six years) and the volatile regulatory climate for nuclear are serious disincentives for potential investors.

Natural gas-fired plants have a clear advantage over coal and nuclear with regard to construction time.

Natural Gas is AbundantConventional Gas Production to Grow Over Next Two Decades

Global gas production will increase over the next 20 years, with growing supplies from both conventional and unconventional resources.

Australasia, Russia and the Former Soviet Union and the Middle East are all expected to increase gas production over the next 15-20 years.

There are many questions still to be answered about the extent of unconventional gas resources, but the potential resources are enormous.

Natural Gas is Safe

The natural gas industry has an excellent safety record, with fewer risks for severe accidents than those presented by other energy sources.

Gas-fired power generation also excels in terms of local environmental safety. Gas-fired plants produce fewer pollutants than coal-fired plants, generating far lower levels of sulfur oxides and nitrogen oxides—primary contributors to acid rain and smog—as well as mercury.

The favorable safety and environmental profile of gas power plants aids in the siting and permitting process.

Natural Gas Generates Jobs and Growth

Natural gas can play a key role in sustainable economic growth.

The natural gas sector generates jobs.– In Canada, the natural gas sector directly employs nearly

190,000 people, and this number rises to 600,000 when indirect employment is included—or more than 3.5% of Canada’s labor force¹

– In the United States, the natural gas industry directly employs more than 620,000 people—and indirectly employs an additional 2.2 million people—for a total of 2.1% of US employment.²

Natural gas creates economic growth.– In the US, the economic value directly added to the economy by

the gas sector is more than $170 billion annually³, in the form of:• Worker salaries• Federal, state and local tax revenue• Royalties• Spending and savings generated from revenues and worker

UK: Natural Gas in the Power Sector Case Study

UK gas demand experienced a jolt in the early 1990s with the introduction of CCGTs into the power mix. – Since 2000, gas demand growth in the UK has

come from power, while all other sectors have trended downward.

Beginning in the early 1990s, the UK system has relied increasingly on CCGTs, which accounted for some 45% of power generation in 2009, growing 10% since 2000.

Due to the rise in natural gas penetration in the power mix since 1990, PFC Energy estimates that the UK achieved a 22% reduction in CO2 emissions by 2007, as compared with the “business as usual” case.

Argentina: Natural Gas in the Transport Sector Case Study

NGV growth in Argentina resulted from: domestic market

dynamics (higher prices for gasoline relative to natural gas) and policy interventions (early support for infrastructure and campaigns emphasizing CNG

safety).

NGV growth in Argentina resulted from: domestic market

dynamics (higher prices for gasoline relative to natural gas) and policy interventions (early support for infrastructure and campaigns emphasizing CNG

safety).

Argentina has the world’s second-largest NGV fleet, and one of the world’s highest penetration rates for NGVs at approximately 20% of the total vehicle fleet. More than 80% of the NGV fleet consists of non-commercial users (private vehicles rather than trucking or taxi fleets).

CNG use in vehicles began in the 1980s, but accelerated throughout the 1990s and particularly the early 2000s due to increasing investments in retail networks. The development of Argentina’s gas pipeline network also facilitated the expansion of CNG.

The initial phase (1984-1988) of the CNG program involved extensive state support and guidance.

In the mid-1980s, early investments in refueling stations and CNG conversions for municipal vehicles were led by the state.

The state company Gas del Estado played a key role in publicizing the virtues of natural gas—promoting it as an inexpensive, safe and environmentally sound alternative—and in certifying the early conversion kits.

Over time, independent retailers became the dominant players in expanding the retail network, and the state’s role diminished to cover only regulations.

South Korea: Natural Gas in the Residential Sector Case Study

The residential sector in South Korea has been quite successful in replacing coal with cleaner-burning natural gas for its heating needs.

PFC Energy calculates a 12% reduction in CO2

emissions by 2007 relative to the “business as usual” case if South Korea had maintained its 1990 fuel mix.

Looking to the future, South Korea plans to further reduce its dependence on oil and coal in its total energy mix and to increase the share of natural gas.– Between 2009 and 2013, oil is expected to lose

3.3% of its market share and coal 1.6%. Over the same period, natural gas’ market share will rise by more than 2%.
