Global Warming Reports
Executive SummaryNew Jersey has begun to make significant strides toward reducing its emissions of global warming pollution, joining other states in the Northeast and across the country in pioneering efforts to reduce global warming pollution from cars and power plants, to boost the state’s energy efficiency, and to increase our use of clean, renewable energy. But the challenges posed by global warming are large, and the need for
additional action to reduce emissions is immediate. Thankfully, many
technologies
and policy tools exist that could enable New Jersey to cut its
emissions of global warming pollutants within the next two decades,
while moving the state toward a clean, secure energy future. This report details 11 policy strategies, in addition to four steps already taken, that would cut New Jersey’s emissions of carbon dioxide—the leading greenhouse gas—by more than 7 percent below today’s levels within the next two decades. Even with these strategies, however, New Jersey will still need to take additional steps to reduce its contribution to global warming in line with the reductions scientists believe will be necessary to prevent catastrophic climate change. Global warming is real, is happening now, and poses a serious threat to New Jersey’s future. • Global average temperatures increased by 1ËšF in
the 20th century and are now increasing at a rate of about 0.36ËšF per
decade. Sea level is rising, ice and snow cover are decreasing, and
hurricane intensity has increased. And the ecological balance upon which life depends would be irrevocably altered. • New Jersey, with its 127 miles of coastline and millions of coastal residents, is susceptible to negative impacts from global warming since much of the land area of the state is low-lying. Sea level rise of 2 to 4 feet would likely cause the inundation of as much as 1 to 3 percent of the state within the next century—including parts of Atlantic City, Cape May, the Delaware Bay Shore, Long Beach Island and the Meadowlands—while leaving large portions of the state susceptible to coastal flooding from major storms. Immediate action is needed to prevent the worst impacts of global warming. Scientists tell us that, if we act quickly and aggressively to reduce global warming emissions, there is a much greater chance of staving off the worst impacts of global warming. To have a reasonable chance of keeping global temperatures from rising by more than 2ËšC (3.6ËšF), the atmospheric concentration of carbon dioxide must be held below 450 parts per million (ppm). To achieve that target, the world will need to halt the growth of global warming pollution in this decade, begin reducing emissions soon, and slash emissions by more than half by 2050. Because the U.S. is the world’s largest global warming polluter, the degree of emission reductions required here will be greater than in less-developed countries. By adopting an aggressive target for reducing global warming pollution and setting in motion the changes that will meet that target, New Jersey can set an example for the rest of the nation, while reducing its own significant contribution to global warming. Emissions of global warming pollution are on the rise in New Jersey. • Between 1990 and 2002, New Jersey’s emissions of carbon dioxide from
energy use increased by 8 percent. Transportation produces the largest
share of carbon dioxide pollution in the state (52 percent), followed
by electricity generation (16 percent), and the direct use of fossil
fuels in homes (13 percent), industry (11 percent) and businesses (8
percent). New
Jersey also produces emissions through the consumption of electricity
generated in other states. New Jersey has already committed to actions that will curb the growth of carbon dioxide emissions over the next two decades. Over the past several years, New Jersey has taken important steps to limit global warming emissions from vehicles and power plants, to improve the energy efficiency of the state’s economy, and to increase the use of renewable energy for electric power generation.
New Jersey could reduce its contribution to global warming by adopting 11 key policy strategies. There are numerous tools available to New Jersey to reduce global warming pollution. 1. Require the sale of energy-saving replacement tires that improve vehicle efficiency without negatively affecting safety. Adoption of these strategies would reduce global warming pollution while improving New Jersey’s energy efficiency. By 2020, New Jersey’s emissions of carbon dioxide would be approximately 6 percent below 2005 levels. By 2025, carbon dioxide emissions would be about 7.4 percent below 2005 levels. New Jersey should commit to reducing its emissions of global warming pollutants to levels consistent with the targets scientists believe we need to meet to avoid catastrophic climate change, and adopt public policies sufficient to achieve those reductions. Specifically, the state should: • Commit to achieving reductions in global warming emissions of 20
percent by 2020 and of at least 70 percent by 2050. Adoption of a
strong cap on global warming emissions at the state, regional or
federal level would ensure that New Jersey achieves that goal. o Requiring owners of passenger vehicles with the lowest fuel efficiency to pay a fee to provide incentives for the purchase of more fuel-efficient vehicles. o Working with other northeastern states to strengthen the Regional Greenhouse Gas Initiative in order to achieve greater reductions in carbon dioxide emissions from the state’s power plants. o Investigating options for additional policies to reduce global warming pollution, especially in areas not directly addressed in this report, such as emissions from air travel and industrial energy use and emissions of global warming pollutants other than carbon dioxide.
