Heaviest building in the world; accommodating the two houses of the Parliament of Romania: the Senate and the Chamber of Deputies, along with three museums and an international conference center. The data represents the global mean emissions for each food product. This can be quite different from the median footprint – which we present here – when there is a significant amount of skew in the data. Skew in food footprint data can arise when impacts are dominated by a small number of high-impact producers.

Transport accounts for around one-quarter of global carbon dioxide (CO 2) emissions from energy. 1 In some countries – often richer countries with populations that travel often – transport can be one of the largest segments of an individual’s carbon footprint.

This makes it difficult to reconcile these warming impacts into a single metric. And our choice of metric can have an impact on how we prioritise GHG reduction strategies: do we first target strong but short-lived gases such as methane? This may slow warming in the short-term – a reasonable argument if we are concerned about approaching temperature-induced tipping points. Or do we focus instead on the persistent CO 2 emissions which will be the primary driver of long-term temperature impacts?Asia Terminals Ltd Logistics Centre".

As in my original post, this data is sourced from the largest meta-analysis of global food systems to date, by Joseph Poore and Thomas Nemecek (2018), published in the journal Science. 7 The study looks at the environmental impacts of foods across more than 38,000 commercially viable farms in 119 countries. This means that beef, lamb and dairy products are particularly sensitive to how we treat methane in our metrics of greenhouse gas emissions. Few would argue that we should eliminate methane completely, but, as explained, there is an ongoing debate as to how to weigh the methane emissions – whether the grey bar should shrink or grow in these comparisons.In the visualization I compare the global average footprint of different food products, with and without including methane emissions. 6 China is, by a significant margin, Asia’s and the world’s largest emitter: it emits nearly 10 billion tonnes each year, more than one-quarter of global emissions.

Alternative sources can include biofuels; hydrogen; electricity from renewable sources, such as wind and solar; or fossil fuels that are less CO 2-intensive than the fuels that they replace.

By incorporating energy efficiency practices into their water and wastewater plant, municipalities and utilities can save 15 to 30% in energy use.

This chart is shown here – with carbon intensity given as the red line. It shows that at very short flight distances (less than 1,000 km), the carbon intensity is very high; it falls with distance until around 1,500 to 2,000 km; then levels out and changes very little with increasing distance. Researchers – David Lee et al. (2020) – estimate that aviation accounts for around 2.5% of global CO 2 emissions, but 3.5% of radiative forcing/warming due to these altitude effects. More national-level information about emissions from the residential and commercial sector can be found in the U.S. Inventory's Trends in Greenhouse Gas Emissions and Energy chapters (Chapters 2 and 4 respectively). TrendsChina had an ecological footprint of 3.71 hectares per capita and a biocapacity of 0.92 per capita in 2017. China’s total ecological footprint is 5.3 billion gha, the highest of any country in the world. China boasts a biocapacity of 1.3 billion hectares, the second-largest in the world (behind Brazil) but also has more people than any other country, which ultimately results in a total ecological deficit of -4 billion gha and a per-capita biocapacity reserve of -2.79—both quite high for a country with such impressive biocapacity. As China’s economy continues to rapidly expand, its citizens' incomes—and their consumption of resources—are rising as well. This unbalanced consumption of resources will likely be one of China's main concerns for the future. 2. United States Direct emissions are produced by burning fuel for power or heat, through chemical reactions, and from leaks from industrial processes or equipment. Most direct emissions come from the consumption of fossil fuels for energy. A smaller amount of direct emissions, roughly one third, come from leaks from natural gas and petroleum systems, the use of fuels in production (e.g., petroleum products used to make plastics), and chemical reactions during the production of chemicals, metals (e.g., iron and steel), and minerals (e.g., cement).
