  2. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    The catalytic converters in engines reduce noxious chemical emission, but also cause ammonia to be released as a byproduct. Operation of a three way catalyst converter type causes this. Newer vehicles have reduced ammonia emissions through modifications such as decreasing exhaust temperatures and increasing air to fuel ratios. [7] [15] < 2%

  3. Ammonia production - Wikipedia

    en.wikipedia.org/wiki/Ammonia_production

    Because ammonia production depends on a reliable supply of energy, fossil fuels are often used, contributing to climate change when they are combusted and create greenhouse gasses. [11] Ammonia production also introduces nitrogen into the Earth's nitrogen cycle, causing imbalances that contribute to environmental issues such as algae blooms.

  4. Emission intensity - Wikipedia

    en.wikipedia.org/wiki/Emission_intensity

    An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).

    Canadian fertilizer company Nutrien Ltd intends to build a $2 billion U.S. plant to produce ammonia with low carbon emissions, it said on Wednesday, in the sector's latest move to meet rising ...

  7. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Ammonia production currently creates 1.8% of global CO 2 emissions. 'Green ammonia' is ammonia produced by using green hydrogen (hydrogen produced by electrolysis with electricity from renewable energy), whereas 'blue ammonia' is ammonia produced using blue hydrogen (hydrogen produced by steam methane reforming (= SMR) where the carbon dioxide ...

    estimating economic costs of facilitating and implementing climate change mitigation and adaptation strategies (varying with the objectives and the levels of action required); see also economics of climate change mitigation. monetising the projected impacts to society per additional metric tonne of carbon emissions (social cost of carbon)

  9. List of countries by carbon intensity of GDP - Wikipedia

    en.wikipedia.org/wiki/List_of_countries_by...

    Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO 2) emissions produced per unit of GDP. It provides an indication of how efficiently an economy uses carbon-based resources to generate economic output .
