The New York Times reported on a new international agreement that will phase out hydrofluorocarbons, or HFCs, a chemical that is used in refrigerators and air conditioners that is a powerful greenhouse gas. The irony is that HFCs were developed to replace chlorofluorocarbons, or CFCs, chemicals that caused a hole in our atmosphere’s ozone layer and were banned by the Montreal Protocol of 1987.

Global communication and global travel have transformed economic life in our world and have been important tools in improving quality of life for many. They have transformed our world’s culture in ways that we do not yet fully understand. Let’s take the first small steps in building the technology and business models most appropriate to a renewable resource-based sustainable economy.
The market and government regulators are sending a message that is clear and ought not be misunderstood: people care about the environment and the quality of their air. If people did not support air pollution regulations they would not have cared about Volkswagen’s disregard of environmental law.
Students in the Master of Public Administration in Environmental Science and Policy (MPA-ESP) program worked this past semester to analyze city-level strategies for reducing greenhouse gas emissions.
While it is true that many nations do not enforce their environmental and occupational health and safety rules, a quick study of economic history demonstrates that the trend is toward more enforcement rather than less enforcement. And even when the government ignores noncompliance with the law, NGOs and consumers notice it.
The huge vertically integrated companies and large factory complexes of the 20th century have been replaced by the networked organization of the 21st. This enables more specialized and efficient production because the cost of shipping is low enough to be easily covered by the reduced costs of production. Shipping of finished products is also increasing as population and consumption increases.
Innovations in the 2014 EPI include a new wastewater treatment indicator; a new approach to climate change indicators; and two new satellite-derived indicators for air quality and forests.
Local food proponents often claim that food grown close to home helps prevent global warming because it requires less fossil fuels to transport, generating fewer greenhouse gas emissions than conventionally produced food. But just how green is local food?
Ninety percent of all existing biomass power plants use wood residue and there are currently 115 power plants in development that will burn biomass to generate electricity. But just how renewable is biomass energy?
As the United States searches for sources of alternative energy and a means to reduce its production of greenhouse gas (GHG) emissions, solar power plants have emerged as a leading candidate to address both of these problems. While these plants do indeed provide an additional means of producting energy that could potentially reduce the amount… read more
