What is the percentage contribution of ghg emission by industrial sector?

Standards of living are difficult to measure, but indicators of social development are available. A basic measure, per capita Gross Domestic Product (GDP), is the value of all goods and services produced within a region over a given time period, averaged per person. A more advanced metric, the Human Development Index (HDI), considers life expectancy, education, and Gross National Income (GNI). The three highest HDI-ranked countries are Norway, Ireland and Switzerland. The Greenhouse Effect The greenhouse effect is a natural phenomenon that insulates the Earth from the cold of space. As incoming solar radiation is absorbed and re-emitted back from the Earth’s surface as infrared energy, greenhouse gases (GHGs) in the atmosphere prevent some of this heat from escaping into space, instead reflecting the energy back to further warm the surface. Anthropogenic (human-caused) GHG emissions are modifying the Earth’s energy balance between incoming solar radiation and the heat released back into space, amplifying the greenhouse effect and resulting in climate change. 1 Greenhouse Gases • There are ten primary GHGs; of these, water vapor (H 2O), carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2O) are naturally occurring. Perfluorocarbons (CF 6, C 2F 6), hydroflurocarbons (CHF 3, CF 3CH 2F, CH 3CHF 2), and sulfur hexafluoride (SF 6) are only present in the atmosphere due to industrial processes. 3 • Water vapor is the most abundant and dominant GHG in the atmosphere. Its ...

You can Our World in Data CO 2 and Greenhouse Gas Emissions database. In discussions on climate change, we tend to focus on carbon dioxide (CO 2) – the most dominant greenhouse gas produced by the burning of fossil fuels, industrial production, and land use change. We cover CO 2 – global emissions, annual, cumulative, per capita, and consumption-based emissions – in great detail in our 2 emissions page. But CO 2 is not the only greenhouse gas that is driving global climate change. There are a number of others – methane, nitrous oxide, and trace gases such as the group of ‘F-gases’ – which have contributed a significant amount of warming to date. Here we look at total greenhouse gas (GHG) emissions across the world, plus breakdowns of other major gases including methane and nitrous oxide. What are the world’s total greenhouse gas emissions every year? How much do we collectively emit? This chart shows the change in global greenhouse gas emissions over time. Greenhouse gases are measured in ‘carbon dioxide-equivalents’ (CO 2e). Today, we collectively emit around 50 billion tonnes of CO 2e each year. This is more than 40% higher than emissions in 1990, which were around 35 billion tonnes. Greenhouse gases have very different warming effects: one tonne of methane does not have the same impact on warming as one tonne of CO 2. Carbon dioxide equivalents (CO 2e) attempt to convert the warming impact of the range of greenhouse gases into a single metric. This is done by multiplyin...

At-a-glance • Nearly 30 percent of U.S. greenhouse gas emissions come from industry, including indirect emissions from the sector’s electricity consumption. • Oil and gas production is the largest manmade source of methane in the United States. • In January 2021, President Biden issued an Executive Order directing federal agencies to review actions taken during the previous administration. Almost a quarter (23 percent) of U.S. greenhouse gas emissions come directly from industrial sources, such as manufacturing, food processing, mining, and construction. These direct emissions result from diverse processes, including the on-site combustion of fossil fuels for heat and power, non-energy use of fossil fuels, and chemical processes used in iron, steel, and cement production. In addition, industry generates indirect emissions from the centrally generated electricity it consumes. The industrial sector makes up about one quarter of total U.S. electricity sales. If direct and indirect emissions are combined, the industrial sector is the largest emitting sector in the U.S. economy, responsible for 29.6 percent of total emissions. Reducing Industrial Emissions There are many ways to reduce greenhouse gas emissions from the industrial sector, including energy efficiency, fuel switching, combined heat and power, use of renewable energy, and the more efficient use and recycling of materials. Many industrial processes have no existing low-emission alternative and will require HFCs Hydr...
