Summary: Using NASA's OCO satellites, we have retrieved large-scale fossil fuel CO2 emissions globally and compared them with a global inventory. The OCO emission retrievals explain more than one third of the inventory variance and show consistent variations in emission levels across different time scales. This suggests that the retrieval-inventory differences are mostly random and trends can be calculated reliably in areas with favorable observing conditions.

Summary: Over the past two decades, the escalating emissions of greenhouse gases from boreal wildfires in the Northern Hemisphere have drawn significant attention, underscoring an unprecedented wildfire season in 2021. Calculations show that wildfires in Russia released approximately 726 +/- 280 Tg CO2eqv yr-1 between 2002 and 2020, surpassing earlier estimates. In 2021 alone, Russia's wildfires emitted an exceptionally high amount of 1,700 Tg CO2eqv, exceeding the carbon emissions from the country's fossil fuel consumption. The Arctic Oscillation (AO) is found to be a predictive variable for wildfires, with over 50% of the variation in wildfire frequency between 2002 and 2021 attributed to shifts in AO.

Summary: India's coal-heavy electricity system is a major contributor to air pollution and greenhouse gas emissions. Our study analyzes the differences in air pollution mortality and the effects of various policies on electricity sector operations in different states of India. We find that coal-dependent states in the east suffer the most from PM2.5 mortality, while renewable energy states in the west and south have shifted their burden to the east through coal generation.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.
