In August 2019, the United Nations Secretary General, António Guterres, named 2020 a make-or-break year for climate policy, not anticipating that the COVID-19 pandemic would bring societies and economies to an abrupt halt, cutting emissions by an amount impossible to imagine under normal conditions.

## Economic downturn in 2020 took pressure off the atmosphere

A growing concentration of the 'critical' greenhouse gases, mainly CO2, CH4, N2O and F-gases, in the atmosphere has been identified as the main cause of increased temperatures on the planet -—

. In 2019, greenhouse gas emissions reached a record high of 52.4 Gt of CO2e. Emissions increased by 1.1 per cent from the previous year after a period of little or no growth from 2015 to 2016, a 1.3 per cent increase in 2017 and a 2.0 per cent increase in 2018. Including emissions from land-use change, which are difficult to measure, total emissions amounted to 57.4 Gt in 2019, according to a report from -—

What do these developments imply for global warming? The year 2020 was one of the three warmest on record, despite the unprecedented drop in emissions seen that year. The annual global temperature was already 1.2°C warmer than pre-industrial conditions -—

According to simulations, reaching the Paris target of keeping global warming below 2°C required emissions of critical greenhouse gases to peak in 2020, and decline sharply thereafter. To remain below 2°C warming by 2100, global emissions should not exceed 40 Gt of CO2e in 2030, and to achieve the below 1.5°C warming target, total emissions should remain below 24 Gt of CO2e by 2030. Remaining below the 2°C target requires a reduction from 2018 levels of nearly 25 per cent and nearly 55 per cent to remain below 1.5°C -—

. Thus, although record-breaking, the forecast reduction of CO2 emissions caused by the COVID-19 outbreak will not be enough to achieve even the weakest of the targets set out by the Paris Climate agreement. Global emissions should be cut by almost 8 per cent every year for the next decade to keep us within reach of the 1.5°C target of the Paris Climate agreement. According to -—

, the estimated 2020 fall in emissions translates to only a 0.01°C reduction of global warming by 2050, due to the increasing concentrations of greenhouse gases in the atmosphere. While emissions dropped in 2020, earlier emissions remain in the atmosphere for long periods.

## Most carbon dioxide emitted in Asia – per unit of GDP and in total

The most prevalent greenhouse gas is CO2, as figure 1 reveals. It is a gas released through human activities, such as deforestation and burning of fossil fuels, and through natural processes, such as respiration and volcanic eruptions. Around 90 per cent of CO2 emissions are generated by burning of fossil fuels in the form of coal, oil and natural gas. However, CO2 concentrations in the atmosphere are also influenced by deforestation and other types of land-cover or land-use change, due to their impact on the land's potential to absorb or generate CO2.

In recent years, CO2 has accounted for almost three quarters of total greenhouse gas emissions. Thus, by focusing on CO2, SDG indicator 9.4.1 helps monitor the largest part, although not the full amount of global greenhouse gas emissions.

The regional concentration of CO2 emissions varies considerably across the globe. In 2019, many countries in Africa recorded emissions of less than 20 kg/km2. In Latin American countries and in Australia, emissions were mainly between 20-100 kg/km2. Much higher CO2 emissions, typically more than 200 kg/km2 and sometimes even higher than 2 000 kg/km2, were common for countries located in a band that ranges from the United States of America and Central America over to Europe, excluding Iceland and most of Scandinavia, and over the Near East, to Southern, Eastern and South-Eastern Asia. Within that band, particularly high emission levels were recorded in Central Europe and Eastern Asia. Farther to the North, in Canada, Northern Europe and in Northern and Central Asia, emission levels were lower, usually ranging between 50 and 200 kg/km2 on average per country.

Notes: CO2 emissions from fossil fuel use (combustion, flaring), industrial processes (cement, steel, chemicals and urea) and product use are included. Emissions from fuels burned on ships and aircrafts in international transport are not included.

As figure 2 shows, three regions of the world emitted most of the CO2 from fuel combustion, industrial processes and product use: Eastern and South-Eastern Asia (15.5 Gt in 2019), Northern America (5.7 Gt) and Europe (6.6 Gt). Together, they accounted for about 75 per cent of global CO2 emissions in 2019. In Europe, one tenth less emissions were associated with each unit of output in Europe than in Northern America. However, as the European economy is larger, measured in terms of GDP, it also accounts for a higher amount of CO2 emissions than the economy of Northern America. Eastern and South-Eastern Asia was characterized by both higher GDP and higher carbon intensity than the other world regions shown in figure 2. The region alone emitted 41 per cent of world’s emissions.

The least CO2 emissions per unit of production were caused by the economies of Latin America and the Caribbean. The economies of Sub-Saharan Africa produced only slightly more CO2 emissions per unit of production than European economies. Sub-Saharan Africa and Latin America and the Caribbean together only contributed 9 per cent of global CO2 emissions, while Europe contributed 17 per cent. Fuels burned on ships and aircrafts involved in international transport, which cannot be allocated to economies, would add about 3 per cent to global CO2 emissions -—

US$values are in constant 2011 prices, adjusted to purchasing power parities based to the United States of America. Central and Southern Asia includes developing economies in Oceania. ## Population growth and rising prosperity drive carbon dioxide emissions Since 1990, global CO2 emissions have increased by two thirds: from 22.7 Gt in 1990 to 38.0 Gt in 2019. This translates to 1.8 per cent average annual growth. Between 2014 and 2016 CO2 emissions remained almost constant, partly due to a sluggish world economy and slowing construction and weak demand for steel. But from 2017 CO2 emissions’ growth resumed, and by 2018 the annual growth rate had returned to 2.3 per cent -— – ‒ - – —- -— – ‒ - – —- -— – ‒ - – —- -— – ‒ - – —- . In 2019, the growth in emissions slowed down, before turning into negative in the face of the outbreak of COVID-19 (see above). Much of the increase in CO2 emissions observed over the last decades relates to world population growth and increased consumption per capita, since consumption relies on the production of goods and services. In fact, CO2 emissions can be expressed as the product of population size, GDP per capita (GDP/population), and the carbon intensity of production (CO2/GDP): An increase in GDP, the product of the first two factors in the equation above, leads to rising CO2 emissions, unless carbon intensity, the third factor, decreases at a higher rate than the growth of GDP. Some studies suggest that carbon intensity decreases as a country's level of development rises, to the extent that GDP growth can be offset. This would result in a bell-shaped relationship between GDP and emissions – the so-called "environmental Kuznets curve". So far, research has provided mixed empirical evidence for the validity of this curve -— – ‒ - – —- -— – ‒ - – —- -— – ‒ - – —- -— – ‒ - – —- . At the global level, real GDP has more than doubled over the last quarter century – from US$49 trillion in 1990 to US$127 trillion in 2019.1 This is the result of a 45 per cent increase in the world population (1971: 5.3 billion, 2019: 7.7 billion) and a three-quarters' increase in real GDP per capita (1990: US$9 290, 2019: US$16 470) (see figure 3). ## Decreasing carbon intensity cannot offset GDP growth in the less developed regions Global carbon intensity reduced by over one third from 1990 (458 g/US$) to 2019 (299 g/US$). That means, CO2 emissions have grown at a slower pace than GDP. This decoupling of CO2 emissions from GDP has been most significant in Europe, where carbon intensity fell by 55 per cent since 1990, and almost as much in Northern America (-49 per cent). Over the past 29 years, carbon intensity has decreased less in regions consisting mainly of developing economies. Eastern and South-Eastern Asia released over three times more CO2 in 2019 than in 1990, reducing carbon intensity by only 27 per cent. Recently, their carbon intensity has been declining notably, from 2012 to 2017 at an annual rate well above 3 per cent. However, the reduction in carbon intensity over the last three decades did not compensate for the extraordinary increase in GDP per capita; it was just enough to offset the population growth. In Sub-Saharan Africa carbon intensity of the economy dropped by 38 per cent from 1990 to 2019, compared to 17 per cent in Latin America and the Caribbean. In Australia and New Zealand, carbon intensity decreased by 34 per cent. Figure 3.

Europe is the only region where the overall amount of CO2 emissions is lower today than in 1990, by almost 30 per cent. Northern America is close to 1990 levels, but the remaining regions are well above.

As countries are connected by global value chains and trade relations, the observed growth in carbon intensity of GDP in developing regions may be driven by demand for carbon-intensive final products in other regions. In fact, studies based on inter-country input-output tables prepared by the -—

## Energy demand dropped in early 2020, but rebounded at the end of the year

Fuels are mostly burned to produce energy. For that reason, CO2 emissions and energy supply are closely interlinked. According to the -—

, this subcomponent of total CO2 emissions, i.e. energy-related CO2 emissions, accounts for two thirds of CO2 emissions globally. Despite an extraordinary decline in energy demand in 2020, energy-related CO2 emissions still reached 31.5 Gt, compared to 33.0 Gt in 2019, according to -—

. They estimate that the global energy demand will increase by 4.6 per cent in 2021, due to the expected recovery from the COVID-19 pandemic.

Energy is an indispensable input for most processes generating value added in an economy. This means that energy intensity (Energy/GDP) is an important determinant of the carbon intensity of GDP (CO2/GDP). The other determinant is the carbon intensity of energy supply (CO2/energy), as the decomposition below shows:

Figure 4 demonstrates the important role of efficient energy use in reducing the carbon intensity of GDP. From 2008 to 2018, energy intensity reduced on average by 1.7 per cent each year. During that time, developing and developed economies in Asia and Oceania achieved significant reductions in energy intensity, by 16 and 17 per cent respectively. However, due to rising emissions per unit of energy supplied, the reduction of carbon intensity of GDP was smaller: 8 per cent in developing and 13 per cent in developed Asia and Oceania. In Latin America and the Caribbean and in Africa, carbon intensity of energy supply remained almost unchanged. Cuts in energy intensity, however, enabled reducing the carbon intensity of GDP also in those regions by 4 and 11 per cent, respectively. By contrast, In Northern America and Europe, both energy intensity and carbon intensity of energy supply were considerably reduced. Due to higher saving in energy per unit of GDP, the overall reduction in carbon intensity of GDP was slightly higher in Northern America (-27 per cent) than in Europe (-23 per cent). Thus, if GDP did not grow, CO2 emissions from fuel combustions would have declined in all regions of the world over the last decade.

Soon after the start of 2020, demand for energy fell sharply due to the measures taken against the COVID-19 pandemic around the world. China, hit by the pandemic first, saw their weekly energy demand fall by 15 per cent, whereas in the Republic of Korea and Japan the estimated impact of COVID-19 measures on energy demand remains below 10 per cent. In Europe, the periods of partial lock down cut weekly energy demand by 17 per cent on average, while countries with a higher share of services and greater stringency of lockdowns saw their energy demand reduce by as much as 25 to 30 per cent. India’s full national lockdown reduced their weekly energy demand by almost 30 per cent. Overall, the IEA estimated that for each additional month of restrictions in place as of early April 2020, global annual energy demand would reduce by 1.5 per cent -—

The impact of COVID-19 has been especially pronounced on transport. Since the outbreak of the pandemic, people have not been travelling much, and the global number of flights collapsed from mid-March 2020. The number of weekly commercial flights available was about 75 per cent lower in the first half of May compared with the start of January 2020. In January 2021, the number of commercial flights remained almost 40 per cent lower than in January 2020. But May 2021, is clearly, by 140 per cent, above the low levels of May 2020 (see Tourism section of Developing economies in international trade).

While air transportation generates about 2 per cent of global emissions, road transportation contributes almost 12 per cent -—

expects road transport activity to recover to pre-COVID-19 levels only in the last months of 2021, while air transport demand would remain markedly below 2019 levels for all of 2021. They expect a partial recovery: CO2 emissions from international aviation would remain one third below pre-pandemic levels in 2021, while emissions from road transport and domestic aviation would remain 5 per cent below 2019 levels.

The impact of COVID-19 brought large changes to the global energy mix in spring 2020. While the share of coal declined to below 23 per cent, renewables jumped to almost 13 per cent. Regional differences were large with major geographic variations -—

. IEA notes that, in 2021, coal demand has rebounded strongly, reversing all the declines in 2020.

These developments led to notable short-term improvements in air quality, with NO2 levels, a gas emitted from burning fossil fuels for transportation and electricity generation, dropping recently. First, in some areas of China, NO2 concentrations dropped by 40 per cent from 2019 levels in January-February 2020. In March 2020, a 30 per cent drop was recorded in the North Eastern part of the United States of America, and the NO2 levels halved in Europe by April 2020 -—

## A mixture of positive and negative trends – what will prevail?

Climate change continues to be a development issue, demonstrated particularly by the trends in Asia, where CO2 emissions have dramatically increased in tandem with the rapid growth of GDP per capita over the last decades. Only decreasing energy intensity has limited the growth of CO2 emissions in that region. This is a sobering message, considering the urgent need to limit the concentration of greenhouse gases in the atmosphere. At the same time, some statistics give hope: in most developed regions, CO2 emissions have been diminishing for more than ten years, despite continuous GDP growth. This provides signs that a decoupling of emissions from the economic development is feasible.

The prolonged outbreak of COVID-19 has brought about an unexpected deviation from many long-term trends, leading to an unprecedented fall of greenhouse gas emissions in early 2020 and a faster shift to renewable energy sources. However, in light of latest data these changes seem temporary. Even if the pandemic has induced historical reductions of CO2 emissions in 2020, it will not be enough in the fight against climate change, and a partial bounce back is expected in 2021. More effective and lasting efforts are needed to reduce CO2 emissions and other greenhouse gases to limit global warming to below 2°C or especially below the 1.5°C target by 2100. As populations and GDP per capita continue to grow, a drastic reduction in carbon intensity will be required. Rising energy efficiency serves as an important step in that direction, as well as renewable and cleaner energy.

## Involving the private sector in the sustainable development agenda

Recent global trends, not the least of which is the COVID-19 pandemic, emphasize the role of sustainability reporting in transitioning to a more sustainable economy. The business sector is identified in the Addis Ababa Action Agenda as a significant player in the financing of sustainable development -—

. Their actions contribute directly or indirectly to the attainment of all SDGs, including the state of the environment and greenhouse gas emissions. Nonetheless, the business sector is mostly absent from the SDG targets and is explicitly mentioned in only one of them: target 12.6, which calls for a greater integration of sustainability information in the regular reporting cycle of firms.

This target and the related reporting are important for making companies’ contribution to the 2030 Agenda visible and for encouraging them to review how their operations affect their stakeholders and the environment. Sustainability reporting promotes transparency in the business sector and increases business accountability to society.

SDG indicator 12.6.1 aims to measure the number of companies that publish sustainability reports. Developing consistent reporting on the indicator requires aligning multiple reporting frameworks, including the International Integrated Reporting Council -—

and the UNCTAD (2018) Guidance on Core Indicators.2

To this end, UNCTAD and UNEP, as joint custodians of SDG indicator 12.6.1, identified four dimensions for sustainability reporting: economic, environmental, social and institutional. As a “minimum reporting requirement”, only reports that cover certain elements in a meaningful way will be counted as sustainability reports for the SDG indicator. To further strengthen sustainable practices and accountability, the agencies also identified an “advanced reporting requirement” with more comprehensive reporting rules.

In September 2019, the IAEG-SDGs approved the concepts and methods developed by UNCTAD and UNEP, and data collection for the indicator began. The framework does not add new reporting requirements, instead it suggests a way to reconcile the existing frameworks.

## Businesses striving to close large gaps in sustainability reporting

UNCTAD regularly convenes a Group of Experts on ISAR to discuss international accounting and reporting standards in order to improve the availability, reliability and comparability of financial and non-financial enterprise reporting, and especially to integrate sustainability information into business reporting.

Official statistics for SDG 12.6.1 are not yet available as companies are setting up the new sustainability reporting. However, an initial review is possible by looking at an unrepresentative sample of company sustainability reports as published by the United Nations Global Compact and GRI Sustainability Disclosure Database. In these samples, in 2020, 85 per cent of companies were reporting on the minimum requirements for SDG indicator 12.6.1 and 40 per cent on the advanced requirements the related UNCTAD Guidance -—

.

In March 2021, the preliminary review was based on a sample of almost 4 000 company reports in the two databases. Although this is a collection of voluntary reports and not representative of the world population of firms, the exercise still provides a first glimpse of current sustainability reporting practices and reveals some regional patterns.

Studying every single report would be time consuming. Instead, machine learning and natural language processing techniques have been used to analyse text syntax structures in the CoPs and identify keywords based on the 33 core elements listed in the UNCTAD Guidance, organised according to the four themes.34

Figure 5 shows that most companies reporting in line with the minimum requirements cover three out of the four reporting dimensions, i.e., economic, environmental, institutional and social dimensions, with the institutional dimension as the least covered dimension. Among companies following the advanced reporting requirements, the environmental dimension has been the most under-reported area.

The largest gaps in minimum reporting relate to indicators such as employee by contract type and gender; stakeholder engagement surrounding sustainability performance; materiality assessment, sustainability strategy and or principles related to sustainability; and employee training. While the largest gaps in advanced reporting include greenhouse gas emissions and waste intensity; material consumption, sourcing of materials and reclaimed or recycled materials used; biodiversity impacts; supplier and consumer engagement on sustainability issues; other local community impacts; supplier social assessment; details of remuneration; and supplier environmental assessment.

Note: These are preliminary results from a non-representative sample. As much as the data on number of company reports reflect compliance with the minimum and advanced requirements, they also reflect current data gaps,

Figure 6 reflects the availability of sustainability reports by reporting requirements and region. The figure also reflects the large data gaps in some regions. Still, these data can be taken as an indication of the regional differences in voluntary reporting. It appears that in certain regions, such as, the Americas, Asia and Europe, firms demonstrate a higher compliance with the UNCTAD Guidance than in others. Larger gaps in reporting of some regions are evident, especially in Africa, Central, Western and Southern Asia and the Oceania.

The overall quality of sustainability reports has improved across the world since the 2017 round of reports, especially in the environmental, social as well institutional and governance dimensions, where the ratio of reporting aligned with the minimum requirements almost doubled in these regions.

All in all, the 2030 Agenda has increased sustainability reporting among businesses and led to closer engagement of international organizations and businesses to develop a commonly agreed upon and harmonized set of indicators. The coming years will show if sustainability reporting will be used by an increasing number of firms to demonstrate commitment to sustainable development.

3. Additional complexity is caused by the fact that the CoPs are reported in over 20 different languages and in different formats. Therefore, the algorithms use multiple data cleaning, noise reduction and filtering methods to better identify relevant content for each indicator.
