An emission intensity 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). Emission intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data. Emission intensities may also be used to compare the environmental impact of different fuels or activities. In some case the related terms emission factor and carbon intensity are used interchangeably. The jargon used can be different, for different fields/industrial sectors; normally the term "carbon" excludes other pollutants, such as particulate emissions. One commonly used figure is carbon intensity per kilowatt-hour (CIPK), which is used to compare emissions from different sources of electrical power.
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO2-equivalent) per unit of comparison. Such units can be for example tonnes CO2-eq per year, per kilogram of protein for consumption, per kilometer travelled, per piece of clothing and so forth. A product's carbon footprint includes the emissions for the entire life cycle. These run from the production along the supply chain to its final consumption and disposal.
The Eco-Management and Audit Scheme (EMAS) is a voluntary environmental management instrument, which was developed in 1993 by the European Commission. It enables organizations to assess, manage and continuously improve their environmental performance. The scheme is globally applicable and open to all types of private and public organizations. In order to register with EMAS, organisations must meet the requirements of the EU EMAS-Regulation. Currently, more than 4,600 organisations and more than 7,900 sites are EMAS registered.
The Environmental Performance Index (EPI) is a method of quantifying and numerically marking the environmental performance of a state's policies. This index was developed from the Pilot Environmental Performance Index, first published in 2002, and designed to supplement the environmental targets set forth in the United Nations Millennium Development Goals.
Carbon accounting is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits. It can also be used to track projects or actions to reduce emissions in sectors such as forestry or renewable energy. Corporations, cities and other groups use these techniques to help limit climate change. Organizations will often set an emissions baseline, create targets for reducing emissions, and track progress towards them. The accounting methods enable them to do this in a more consistent and transparent manner.
The Food and Agriculture Organization Corporate Statistical Database (FAOSTAT) website disseminates statistical data collected and maintained by the Food and Agriculture Organization (FAO). FAOSTAT data are provided as a time-series from 1961 in most domains for 245 countries in English, Spanish and French.
Greenhouse gas inventories are emission inventories of greenhouse gas emissions that are developed for a variety of reasons. Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric models. Policy makers use inventories to develop strategies and policies for emissions reductions and to track the progress of those policies.
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2017 were 425±20 GtC from fossil fuels and industry, and 180±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2017, coal 32%, oil 25%, and gas 10%.
The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person. In 2019 China is estimated to have emitted 27% of world GHG, followed by the United States with 11%, then India with 6.6%. In total the United States has emitted a quarter of world GHG, more than any other country. Annual emissions are over 15 tons per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person. However, the IEA estimates that the richest decile in the US emits over 55 tonnes of CO2 per capita each year. Because coal-fired power stations are gradually shutting down, in the 2010s emissions from electricity generation fell to second place behind transportation which is now the largest single source. In 2020, 27% of the GHG emissions of the United States were from transportation, 25% from electricity, 24% from industry, 13% from commercial and residential buildings and 11% from agriculture. In 2021, the electric power sector was the second largest source of U.S. greenhouse gas emissions, accounting for 25% of the U.S. total. These greenhouse gas emissions are contributing to climate change in the United States, as well as worldwide.
Germanwatch e.V. is a non-profit, non-governmental organization based in Bonn, Germany. It seeks to influence public policy on trade, the environment, and relations between countries in the industrialized north and underdeveloped south. The organization collates a variety of economic and social data to formulate position papers, often in partnership with other NGOs. Particular areas of interest include trade in food and agricultural policy, climate change, and corporate accountability.
The Ibrahim Index of African Governance (IIAG), established in 2007, provides an assessment of the quality of governance in African countries. The IIAG is compiled by 81 indicators and 265 variables from 54 data projects, coming from 47 independent African and international data sources. Published every two years, the IIAG is one of the world’s most comprehensive collections of data on African governance.
Climate change has received significant scientific, public and political attention in Sweden. In 1896, Swedish chemist Svante Arrhenius was the first scientist to quantify global heating. Sweden has a high energy consumtion per capita, but reducing the dependency on fossil energy has been on the agenda of cabinets of the Governments of Sweden since the 1970s oil crises. In 2014 and 2016, Sweden was ranked #1 in the Global Green Economy Index (GGEI), because the Swedish economy produces relatively low emissions. Sweden has had one of the highest usages of biofuel in Europe and aims at prohibiting new sales of fossil-cars, including hybrid cars, by 2035, and for an energy supply system with zero net atmospheric greenhouse gas emissions by 2045.
The Good Country Index measures how much each of the 163 countries on the list contribute to the planet, and to the human race, through their policies and behaviors.
The German Climate Action Plan 2050 is a climate protection policy document approved by the German government on 14 November 2016. The plan outlines measures by which Germany can meet its various national greenhouse gas emissions reduction goals through to 2050 and service its international commitments under the 2016 Paris Climate Agreement. The Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB), under minister Barbara Hendricks, led the development of the plan. The plan was progressively watered down since a draft was first leaked in early May 2016. Projections from the environment ministry in September 2016 indicate that Germany will likely miss its 2020 climate target.
Climate change is leading to long-term impacts on agriculture in Germany, more intense heatwaves and coldwaves, flash and coastal flooding, and reduced water availability. Debates over how to address these long-term challenges caused by climate change have also sparked changes in the energy sector and in mitigation strategies. Germany's energiewende has been a significant political issue in German politics that has made coalition talks difficult for Angela Merkel's CDU.
Coal, cars and lorries vent more than a third of Turkey's six hundred million tonnes of annual greenhouse gas emissions, which are mostly carbon dioxide and part of the cause of climate change in Turkey. The nation's coal-fired power stations emit the most carbon dioxide, and other significant sources are road vehicles running on petrol or diesel. After coal and oil the third most polluting fuel is fossil gas; which is burnt in Turkey's gas-fired power stations, homes and workplaces. Much methane is belched by livestock; cows alone produce half of the greenhouse gas from agriculture in Turkey.
Climate change in Algeria has wide-reaching effects on the country. Algeria was not a significant contributor to climate change, but, like other countries in the Middle East and North Africa (MENA) region, is expected to be among the most affected by climate change impacts. Because a large part of the country is in already hot and arid geographies, including part of the Sahara, already strong heat and water resource access challenges are expected to get worse. As early as 2014, scientists were attributing extreme heat waves to climate change in Algeria. Algeria was ranked 46th of countries in the 2020 Climate Change Performance Index.
Climate change is expected to significantly impact Morocco on multiple dimensions, similar to other countries in the Middle East and North Africa region. As a coastal country with hot and arid climates, environmental impacts from climate change are likely to be wide and varied. Analysis of these environmental changes on the economy of Morocco are expected to create challenges at all levels of the economy. The main effects will be felt in the agricultural systems and fisheries which employ half of the population, and account for 14% of GDP. In addition, because 60% of the population and most of the industrial activity are on the coast, sea level rise is a major threat to key economic forces. Morocco’s average temperatures have increased by 0.2 °C per decade since the 1960s. Morocco is particularly susceptible to heat waves, droughts and floods.
Niklas Höhne is a German scientist in the field of national and international climate policy and mitigation of greenhouse gas emissions. He is founder of the NewClimate Institute in Cologne, Germany and professor at Wageningen University.
Climate change in the Middle East and North Africa (MENA) refers to changes in the climate of the MENA region and the subsequent response, adaption and mitigation strategies of countries in the region. In 2018, the MENA region emitted 3.2 billion tonnes of carbon dioxide and produced 8.7% of global greenhouse gas emissions (GHG) despite making up only 6% of the global population. These emissions are mostly from the energy sector, an integral component of many Middle Eastern and North African economies due to the extensive oil and natural gas reserves that are found within the region. The region of Middle East is one of the most vulnerable to climate change. The impacts include increase in drought conditions, aridity, heatwaves and sea level rise.
