  • Reduction of greenhouse gases in developing countries

    The Clean Development Mechanism (CDM) is an arrangement under the Kyoto Protocol allowing industrialized countries with a green house gas reduction commitment (called Annex 1 countries) to invest in projects that reduce emissions of GHGs in developing countries as an alternative to more expensive emission reductions in their own countries. The most important factor of a carbon project is that it ...


  • Greenhouse Gases-California-Things to Know

    Here are some things to know about California Gov. Jerry Brown's new target for reducing carbon emissions that contribute to climate change. WHAT DO THE NUMBERS MEAN? Brown set a goal for the state to reduce emissions to 40 percent below what they were in 1990. Countries set that year as a benchmark for climate change when they signed on to the U.N. Kyoto Protocol, an ...

  • Fuel a small part of construction`s greenhouse impact

    The best way for Canadian construction to reduce its energy consumption will not necessarily be found in how it powers its work, says a leading energy research analyst. "The energy consumed in construction products is 35 to 40 per cent of the grand total of energy consumed in Canada. The ‘stuff’ that construction needs to make 'stuff is energy intensive," said John Nyboer, executive ...

  • Submission on the future work of the Ad-hoc working group on the Durban Platform for Enhanced Action (ADP)

    During its first session held in Bonn from 17.25 May 2012, the ADP agreed on its Bureau, adopted its agenda and initiated two work streams, one addressing matters related to paragraphs 2.6 of decision 1/CP.17 and another addressing matters related to paragraphs 7.8 of that same decision.

  • New EPA ruling deems greenhouse gases (GHGs) harmful to humans

    Greenhouse Gases (GHGs) will be categorized as a pollutant following the US Supreme Court's landmark notice approving the Environmental Protection Agency’s (EPA) ruling. The gases harm the environment as they have proved to increase heat trapping chemicals in the atmosphere. These chemicals, commonly taking the form of refrigerant gases, originate from a variety of systems, including ...

  • Modelling water requirements of greenhouse spinach for irrigation management purposes

    Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

  • Evaluation of greenhouse gas emissions and design of mitigation options: a whole farm approach based on farm management data and mechanistic models

    Agricultural activities are important sources of nitrous oxide (N22O), methane (CH4) and carbon dioxide (CO2). They contribute approximately 10% of the total emitted greenhouse gases (GhG) in the European Union. We search for evaluating GhG emissions at the farm level and designing mitigation options. As emissions occur at many stages within the farm operation, it is crucial to ...

  • Environmental input–output analysis of the New Zealand dairy industry

    This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only ...

  • Influence of urea fertilizer placement on nitrous oxide production from a silt loam soil

    Received for publication April 8, 2009. Urea placement in band or nests has been shown to enhance N use efficiency, but limited work has been done to assess its affect on N2O emissions. This study compared N2O emissions from urea prills applied to an Amsterdam silt loam (fine-silty, mixed, superactive, frigid Typic Haplustolls) using broadcast, band, and nest placements. Experiments were ...
