(10 August 2021) "Climate change is irreversible." This was perhaps the most significant conclusion of the most recent report by the Intergovernmental Panel on Climate Change (IPCC). The report, a product of the combined efforts of 234 scientists from 66 countries, projects that in the coming decades climate changes will increase in all regions of the globe, with increasing heat waves, longer warm seasons, and shorter cold seasons.

Other key findings from the IPCC report:

  • Sea level will continue to rise, and the likelihood of crossing the global temperature increase level of 1.5°C (relative to the preindustrial period, approximated by the period 1850-1900) in the next few decades is very high.
  • The observed warming is driven by emissions from human activities. Based on improved observational datasets to assess historical warming, as well progress in scientific understanding of the response of the climate system to human-caused greenhouse gas emissions, the IPCC estimates that human activities are responsible for 95% of observed global warming.

Carbon Majors' GHG Footprint Revealed

(10 June 2021) While 30% of the world's largest corporations have already made a commitment to reducing carbon emissions, there are other companies whose economic activity is inextricably linked to greenhouse gas (GHG) emissions and for whom reducing their carbon footprint is barely feasible — the so-called "carbon majors." In its 2020 Carbon Majors report, the Climate Accountability Institute estimates that between 1965 and 2018, 493 billion tons of greenhouse gases (in CO2 equivalent), or 35% of global GHG emissions from fossil fuels and cement production, were emitted from the...

Which Countries Have the Most Ambitious 2030 Emissions-Reduction Targets?

Climate change is recognized as a significant issue for people's lives and economic well-being worldwide. Since greenhouse gas (GHG) emissions are associated with climate change, many countries have been making efforts to regulate and limit them. Under the 2015 Paris Agreement, countries pledged to advance climate change mitigation by committing to national GHG reduction targets. In 2015, the countries submitted their first national strategies, known as Nationally Determined Contributions or NDCs, for reducing their share of greenhouse gases by 2030. The data visualizations below...

Carbon Pricing Initiatives Are Gaining Momentum

(26 July 2021) According to the World Bank’s State and Trends of Carbon Pricing 2021, there are 64 carbon pricing schemes in operation around the world today, covering over 21% of global emissions and generating over $50 billion of revenue per year. Though the share of global greenhouse gas (GHG) emissions covered by carbon pricing initiatives is growing fast, with a threefold increase over the last decade, experts note that thus far less than 4% of global emissions are covered by a carbon price higher than $40 per ton of carbon equivalent — the price they warn is needed to meet...

The True Carbon Emission Country Ranking

(02 December 2021) As governments and businesses aim to reduce carbon footprint to meet climate targets, measuring carbon emissions at global, country, and corporate levels has become extremely important. A key tool designed to reduce carbon footprint is carbon pricing/taxation, in which a government sets a price (or a carbon tax) that emitters must pay for each ton of greenhouse gas emissions they emit. Existing carbon pricing schemes tax only current carbon flows, but what about carbon emissions of the past? Who should pay for these? Using Global Carbon Atlas data on fossil fuel...
