  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Ozone-depleting substances 2015

    Aggregated data reported by companies on the import, export, production, destruction, and feedstock and process agent use of ozone-depleting substances in the European Union Executive Summary Background Chemicals known to harm the ozone layer have been successfully substituted in most parts of the world since 1989, when the Montreal Protocol on Substances ...

  • Can trading pollution like stocks help fight climate change?

    The gas produced by hog manure at farms across the U.S. punches holes in the ozone layer, overheats the planet, and angers neighbors with its peculiar odor, a mix of rotten egg and ammonia. All that's needed to clear the air is to cover the manure with a system of tarps that captures the gas, but many farms don't do it because it's too expensive. "If you don't give people incentives to come up ...

  • Closing the Emissions Gap – 2015 is a year of unprecedented opportunity

    A new report released by the Global Commission on the Economy and the Climate identifies ten key economic opportunities that could close up to 96 percent of the gap between business-as-usual emissions and the level needed to limit dangerous climate change. The report calls for stronger cooperation between governments, businesses, investors, cities and communities to ...

  • Want to change the future? Pay attention to the past.

    From Mandela to MLK to McKibben, history offers lessons aplenty for climate activists We all know the plotline: Single-minded, passionate activists attempt to take on immense money and power, hidebound ideology and bureaucratic paralysis to turn the tide on the most important issue ever. We could be talking about climate change. But we could also be talking about the abolition of ...

  • South LA: CFC Case Study (C3 Technology)

    The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), dichlorodifluoromethane ...

  • Nor Cal 2002 Case Study (C3 Technology)

    The project site is located in Northern California and was leased and operated as a chemical storage and solvent recovery operation from late 1972 through April 1993. During an earlier period, the site may also have been used as a waste transfer station. Previous investigations indicate that soil and groundwater at the site, and groundwater down-gradient (westward) from the site, have been ...

  • Maintaining regulatory method compliance while automating oil and grease analysis

    Regulatory compliance is at the heart of environmental analyses throughout the world. While some regulatory systems provide more flexibility in the methodology used for measuring contaminants, the goal is to gain reliable information that can be used for decision-making. Oil and grease measurement is a simple and important measurement of water quality, but time consuming1. Methods such as US EPA ...

  • New Climate Action Report: U.S. Can Reach its Emissions-Reduction Goal, but Only With Ambitious Action

    On 26th October, the Obama Administration released the sixth U.S. Climate Action Report (CAR6) for public review, to be submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in January 2014. The report, which all developed countries are required to complete, outlines U.S. historical and future greenhouse ...

  • Can the U.S. get there from here? Using existing federal laws and state action to reduce greenhouse gas emissions

    U.S. greenhouse gas emissions are expected to rise unless additional policy actions are taken. This report identifies a suite of policies that the Administration can pursue that do not require new legislation by the U.S. Congress. If pursued with “go-getter” level ambition, those policies can reduce U.S. emissions 17 percent below 2005 levels in 2020. Key Findings Without new ...

  • Environmental risks of new–generation fluorocarbons in replacement of potent greenhouse gases

    This article aimed to address two categories of environment friendly fluorocarbons (i.e., hydrofluoroethers and hydrofluoro–olefins), which are used as replacements for potent greenhouse gases like hydrochlorofluorocarbons (HCFC) and hydrofluorocarbons (HFC). In the work, the author will introduce the new–generation fluorocarbons on the basis of their excellent data on the ...

  • Ozone-depleting substances 2011 - Summary

    In 1989 the Montreal Protocol on Substances that Deplete the Ozone Layer entered into force. It has the objective of protecting the stratospheric ozone layer by phasing out the production of substances that contribute to ozone depletion. The Protocol covers over 200 individual substances with a high ozone.depleting potential, including chlorofluorocarbons (CFCs), halons, hydrochlorofluorocarbons ...

  • Asia–Pacific Analysis: Safer path needed for e-waste

    Instead of limiting imports of electronic waste, the Asia–Pacific region should set up a robust recycling system, says Crispin Maslog. Garbage in, garbage out is a phrase to describe what happens when computers find the wrong solution in response to the wrong input data. But when computers and other electronic products have outlived their usefulness, they literally do become rubbish ...

  • What is ambition in the context of climate change?

    Ambition is a word often used in the context of United Nations Framework Convention on Climate Change (UNFCCC) negotiations. While most people think of ambition as a strong desire to achieve something, the word has a more specific meaning when it comes to international climate action. What Does Ambition Mean and Why Is it ...

  • Use of ejectors in cascade refrigeration systems for exergetic performance improvement

    In this paper an expansion cascade refrigeration system are compared to cascade systems using ejectors. This comparison is made for a variety of fluids. Natural fluids and hydrofluorocarbons (HFCs) are used in the two loops. Theoretical models are written using FORTRAN. The thermodynamic parameters of fluids are given using the software REFPROP 8.0. For fixed working conditions, using CO ...

  • Recent USEPA Rulings To Reduce GHGs

    Over the last few months the USEPA has begun to implement rules to reduce greenhouse gas (GHG) emissions. Not the traditional way by having affected facilities measure and reduce GHG emissions, but instead by encouraging operational changes to accomplish the same goal. 2 rulings that can affect businesses are discussed here. 1. Alternative refrigerants. This past December the USEPA announced ...
