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.

This report explores unique opportunities and challenges for the Southeast region (Alabama, Georgia, Mississippi, North Carolina, South Carolina, and Tennessee) in the broader context of the transformative changes to the U.S. energy system that are required to reduce carbon dioxide (CO2) emissions to net-zero emissions in 2050.

The implementation of better public spending practices can play a critically important role in helping countries make progress towards the Sustainable Development Goals (SDGs). As governments globally are starting to recognise, public sector procurement is more than simply an operational function—it can be a powerful force for change.

Low-carbon investment was driven by companies in the high-emitting materials, energy and transport sectors, accounting for 5, 38 and 50 percent respectively.

In 2019, the EU electricity sector emitted 12 per cent less CO2 than in the previous year. At the same time, the share of renewables in electricity production rose EU-wide to 35 per cent, a new record. These are the main findings in a study of current electricity data carried out by Agora Energiewende and climate think-tank Sandbag. Greenhouse gas emissions from EU power plants declined more sharply in 2019 than in any year since at least 1990. All in all, emissions fell by 120 million tonnes, a decrease of 12 per cent relative to the previous year’s level.

By many measures, the world is still in the early stages of a deep and profound transformation in energy, and industrial and agricultural processes. The aim of that transition is to achieve new policy goals for modern societies – among them, deep cuts in carbon dioxide and other warming gases.

A key challenge in the collective endeavour to combat the climate emergency is the shift of global investment and financing flows that underpin current and future growth to low-carbon, climate-resilient (LCCR) growth.

This report explores unique opportunities and challenges for the Midwest region in the broader context of the transformative changes to the U.S. energy system that are required to reduce carbon dioxide (CO2) emissions to net-zero emissions in 2050. The scale and rate of physical changes to the U.S.

This paper assesses the overall costs and distributional impacts of China’s planned nationwide emissions trading system for CO2 emissions reductions, a system that will differ from cap and trade and become the largest CO2 trading system in the world.

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.
