  • Biomass Calculator Launched

    A scientific calculator has been developed that investigates the impact on carbon emissions of biomass sourced from North America to produce electricity. The calculator finds that biomass, when sourced responsibly, can be used in a low carbon and sustainable way. The government’s Bioenergy Strategy published in 2012 made clear only bioenergy from sustainable sources should be used. In ...

  • Launch of the 2050 Global Calculator

    It’s great to see so many of you here today. I hope I’m not being presumptuous by saying that your presence here means that we all share a common understanding – and a common objective. Everyone here understands we need to follow the science – man-made climate change is real, is already happening, and represents one of the most serious threats facing the UK, and the planet ...

  • Climate models may be overestimating the cooling effect of wildfire aerosols

    Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

  • Grasshopper Launches Calculator Tool for Fuel Expense, Emissions, Profitability

    The Grasshopper Company -- manufacturer of commercial zero-turn riding mowers -- announces a new online tool designed to calculate fuel costs and impact of commercial mowing equipment.

  • Complying with emissions regulations: calculating the acid plume from ships’ desulphurisation equipment

    Marine diesel contains sulphur compounds, which generate sulphur oxide (SOx) pollution and acid rain. Ships can use mitigating technologies to reduce their SOx emissions, but these can also have a negative environmental impact. The International Maritime Organization (IMO) introduced stringent legislation to control these, aspects of which are incorporated into EU policy. This study examined the ...

  • New add calculation pop-up

  • Calculating carbon payback times for biofuels

    Biofuels can only contribute to reducing greenhouse gas (GHG) emissions if crop production does not lead to further deforestation in tropical regions. New research introduces the concept of ecosystem carbon payback time (ECPT), which can be used to help identify the best means of expanding biofuel production worldwide, without causing unacceptable levels of carbon emissions from crop production. ...

  • CSX introduces improved carbon calculator

    As millions of Americans head to stores or make online purchases, CSX has launched an improved Carbon Calculator aimed at helping consumers and businesses better understand the key role freight rail plays in a sustainable supply chain.  “CSX’s online Carbon Calculator not only helps our customers make smart supply chain decisions, it also helps educate consumers about the path ...

  • Calculating the environmental cost of uranium mining

    Nuclear power is receiving growing attention from governments seeking ways to cut greenhouse gas (GHG) emissions. However, there is little detailed analysis of the true carbon costs of the nuclear industry. A new analysis suggests that eco-efficiency of uranium mining and milling, a key aspect of the efficiency of nuclear power generation, depends on the amount of uranium in the rocks being ...

  • Siemens Introduces Environmental Impact Calculator

    Siemens Building Technologies announced today it has introduced the Environmental Impact Calculator, a new application now available free-of-charge through the Apple Store.
