    NEW JERSEY GREENHOUSE GAS INVENTORY MID-CYCLE UPDATE REPORT February 2021 Introduction New Jersey’s Global Warming Response Act (GWRA) (P.L. 2007, c.112, as amended 2019) calls for an annual compilation of statewide greenhouse gas (GHG) emissions data. This data is used to monitor and track progress towards New Jersey’s goal of reducing GHG emissions 80% from their 2006 levels by 2050 (known as the 80x50 goal).1 Since 2008, the New Jersey Department of Environmental New Jersey’s Greenhouse Gas Protection (DEP) has released a comprehensive statewide Reporting Framework GHG inventory report approximately every two years. Following the 2019 amendments to the GWRA, the DEP is also Emissions Inventory Report committed to releasing updated data annually to help inform • Full report released every two years the state’s climate mitigation planning and implementation • Includes the latest emissions estimates and projections efforts. • Includes a detailed discussion on: The DEP will therefore continue to release a full Emissions o Statewide Greenhouse Gas trends Federal and International trends Inventory Report every other year and will also provide a o and policy “Mid-Cycle Update” during the intervening years. The o Changes in methodologies Emissions Inventory Reports2 contain detailed analysis, o Adjustment of Baselines including updated emissions calculations, review of GHG trends, adjustments to baselines (when necessary), and Mid-Cycle Update • Brief summary released between discussion of any changes in emission calculation Emissions Inventory Reports methodologies.

  • The Global Warming Potential Is Inconsistent with the Physics of Climate Change and Misrepresents the Effects of Policy Interventions
    https://www.essoar.org/doi/10.1002/essoar.10504991.1 Poster SY012-0005 The Global Warming Potential is Inconsistent with the Physics of Climate Change and Misrepresents the Effects of Policy Interventions Robert L. Kleinberg Boston University Institute for Sustainable Energy https://www.essoar.org/doi/10.1002/essoar.10504991.1 METHANE AS AN ENERGY SOURCE AND A GREENHOUSE GAS SUMMARY: Methane, the primary component of natural gas, is both a useful primary source of energy and a powerful greenhouse gas. It is as important as carbon dioxide in determining whether we meet our 2050 climate goals. --------------- Natural gas (blue bars) is the most versatile source of primary energy in the US energy system, serving power, residential, commercial, and industrial sectors. https://www.essoar.org/doi/10.1002/essoar.10504991.1 Natural gas plays a unique role in energy storage. Every winter it feeds about 500 terawatt- hours of energy into power and heating systems. There is no other energy storage system that has anywhere near this capability, in overall capacity and ability to store energy for seasonal use. https://www.essoar.org/doi/10.1002/essoar.10504991.1 The primary constituent (90-95%) of pipeline grade natural gas is methane, which when emitted directly to the atmosphere is a powerful greenhouse gas. Globally, about half of methane emissions are from natural sources (green segments) and the other half are anthropogenic (other colors). https://www.essoar.org/doi/10.1002/essoar.10504991.1 Methane is 120 times more powerful as a greenhouse gas than carbon dioxide, on a per- kilogram basis.

  • Greenhouse Gas Inventory
    GREENHOUSE GAS INVENTORY UNIVERSITY of NORTH CAROLINA WILMINGTON August 2014 2 LETTER FROM THE CHIEF SUSTAINABILITY OFFICER As North Carolina’s coastal university, the University of North Carolina Wilmington defines itself by a strong connection to the environment through teaching, research and community engagement. UNCW considers its surroundings more than a backdrop for the successes that characterize the university. The environment is the main stage that much be preserved in order to continue such great academics, research and service learning. UNCW defines sustainability as individual efforts made by the community to ensure that the beauty and benefits of today’s world – economically, environmentally and socially – will be available for future generations to inherit. The university is committed to maintaining fiscal responsibility and believes that its efforts in sustainability reflect that. Consequently, sustainability involved awareness and understanding of the complex interdependence between these social, economic and ecological systems. The choices we, as Seahawks, make in our daily lives affect the intricate interconnections between these systems both seen and unseen. In recent years, the need to innovate and reduce the “talon-print” of our community, region and state became apparent. The initial wave of change may have originated on a political level, but as the movement has gained momentum, the tides have changed and the obligation to sustainability has developed as an individual as well as institutional commitment. As you will see in this report, UNCW has taken great strides in areas of energy conservation, alternative transportation, recycling, as well as stewardship in natural areas. Much work remains; however, through the hard work of the Sustainability Council and collaboration with peers and partners, we will continues the process of improvement.
