In the following, a short introduction to input-output analysis and its environmental extension for the calculation of material footprints or RME indicators is provided. . The inter-industry flows within an economy form an n×n matrix Z and the total output of each industry forms an n×1 vecto
Renewable energy in South Africa has the potential to increase access to electricity in rural areas because of its suitability for off-grid and small-scale solutions. The barriers of renewable energy in the country include lack of political stability and capacity, marginalization, corruption, poverty, and environmental degradation. [ 48 ]
In 2012, international maritime transport made up 2.2% of global emissions. [3]: 9 In 2014, the IMO calculated that the shipping industry produced 3.1% of all CO 2 emissions, [4] and that shipping emissions would rise as much as 250% by 2050, [3]: 17 at which point they could make up 17% of all emissions.

The IPCC Sixth Assessment Reports defines carbon budget as the following two concepts: [2]: 2220 "An assessment of carbon cycle sources and sinks on a global level, through the synthesis of evidence for fossil fuel and cement emissions, emissions and removals associated with land use and land-use change, ocean and natural land sources and sinks of carbon dioxide (CO 2), and the resulting ...
The term carbon in low-carbon economy is short hand for all greenhouse gases. The UK Office for National Statistics published the following definition in 2017: "The low carbon economy is defined as economic activities that deliver goods and services that generate significantly lower emissions of greenhouse gases; predominantly carbon dioxide."
The carboNZero programme and CEMARS programme are the world’s first internationally accredited greenhouse gas (GHG) certification schemes under ISO 14065. They provide tools for organisations, products, services and events to measure and reduce their greenhouse gas emissions (otherwise known as carbon footprint), and optionally offset it.
The Middle East and North Africa currently faces extreme water scarcity, with twelve out of the 17 most water stressed countries in the world deriving from the region. [35] The World Bank defines an area as being water stressed when per person water supplies fall below 1,700 cubic metres per year. [36]
Emissions reduction currency is also different from a voluntary carbon offset where a payment is made, typically to fund alternative energy or reforestation, the emissions reduction or sequestration resulting from which is used to reduce or cancel the payers responsibility for emissions produced by themselves. The value of an offset is in its ...
