The 2020 Environmental Performance Index (EPI) provides a data-driven summary of the state of sustainability around the world. Using 32 performance indicators across 11 issue categories, the EPI ranks 180 countries on environmental health and ecosystem vitality.

Around two-thirds of global GHG emissions are directly and indirectly linked to household consumption, with a global average of about 6 tCO2eq/cap. Changes in consumption patterns to low-carbon alternatives therefore present a great and urgently required potential for emission reductions. In this paper, we synthesize emission mitigation potentials across the consumption domains of food, housing, transport and other consumption.

This paper provides the first comprehensive social welfare estimates of recent fuel economy and greenhouse gas emissions standards.

The tell-tale physical signs of climate change such as increasing land and ocean heat, accelerating sea level rise and melting ice are highlighted in this new report released by the World Meteorological Organization on March 10, 2020.

Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task.

Human-emitted greenhouse gases (GHGs) have resulted in a long-term and unequivocal warming of the planet. More than 90% of the excess heat is stored within the world’s oceans, where it accumulates and causes increases in ocean temperature.

The global economy has suffered a significant slowdown amid prolonged trade disputes and wide-ranging policy uncertainties.

Equilibrium climate sensitivity, the global surface temperature response to CO$_2$ doubling, has been persistently uncertain. Recent consensus places it likely within 1.5‐4.5K. Global climate models (GCMs), which attempt to represent all relevant physical processes, provide the most direct means of estimating climate sensitivity.

The degradation of biomass during storage leads to several unfavourable outcomes including greenhouse gas (GHG) emissions, feedstock/energy losses, and economic losses.

This paper introduces the Agro-Chain Greenhouse Gas Emissions (ACGE) calculator, a calculator for estimating GHG emissions for food supply chains that addresses emissions due to agricultural production and post-harvest activities.
