The importance of multiregional accounting for corporate carbon emissions Open
Corporations routinely use environmentally-extended input-output models to estimate and report greenhouse gas emissions upstream in their supply chains. However, the most widely used models assume that supply chains and emissions intensiti…

The global hydrogen budget Open
Hydrogen (H2) will play a part in decarbonizing the global energy system1. However, hydrogen interacts with methane, ozone, and stratospheric water vapour, leading to an indirect 100-year global warming potential of 11 ± 4 (refs. 2-5). Thi…

Economic development, air conditioning and adaptation to warming Open
Rising global temperatures increase the potential for heat-related adverse impacts, while economic growth, by enabling greater adoption of air conditioning, can help reduce them. This makes it unclear in which countries the net effect will…

A near-real time daily European Power Consumption and Carbon Intensity Dataset (ECON-PowerCI) Open
We present a near-real-time daily European Consumption-based Power Carbon Intensity Dataset (ECON-PowerCI), developed from the CarbonMonitor power production dataset for Europe. Spanning from January 2015 to December 2024, the dataset enco…

Long-range PM2.5 pollution and health impacts from the 2023 Canadian wildfires Open
Smoke from extreme wildfires in Canada adversely affected air quality in many regions in 20231,2. Here we use satellite observations, machine learning and a chemical transport model to quantify global and regional PM2.5 (particulate matter…

The climate implications of failing to manage carbon Open
In scenarios that limit the increase in global mean temperature (GMT) this century to 1.5 or 2°C, large quantities of carbon are managed by both carbon capture and storage (CCS) at point sources and atmospheric carbon dioxide removal (CDR)…

Residual emissions may perpetuate community-scale inequalities of U.S. air pollution in net-zero scenarios Open
Achieving net-zero emissions targets reduces GHGs and thus improves air quality, but the magnitude and distribution of these improvements will depend on specific mitigation decisions, such as the amount and location of residual emissions b…

Increasing risk of heat stress at the Summer Olympics Open
Rising temperatures under climate change threaten athlete safety at the Summer Olympics due to increasing heat stress likelihoods. For outdoor sports, suspending activity (i.e. rescheduling or cancelling) is the only possible intervention …
Harmonized Annual Averaged Traffic Data at Street Segment Level for European Cities Open
Traffic flow data in Europe are collected locally by city authorities using different systems and standards, making it difficult to compare cities or evaluate large-scale maps, such as those used for emission inventories. To address this g…

Europe's adaptation to the energy crisis: reshaped gas supply–transmission–consumption structures and driving factors from 2022 to 2024 Open
The 2022 invasion of Ukraine by Russia triggered a significant energy crisis in the EU27 (27 EU member countries) and UK (hereafter EU27&UK), leading to profound changes in their natural gas supply, transmission, and consumption dynamics. …

The key to reducing steel emissions may be using aluminum instead Open
Steelmaking is a major source of difficult-to-abate carbon dioxide (CO2) emissions. Here, we analyze decarbonization pathways for both aluminum and steel by considering five production routes, including the fossil fuel-based processes that…

Historical trends in snowmelt used for irrigation Open
Many agricultural regions rely on snowmelt runoff as a source of water for irrigation, but climate change is altering runoff dynamics, making it difficult to meet increasing irrigation water demands. It remains unclear whether irrigation w…

Natural Carbonation of Alkaline Industrial Wastes: A Large-Scale, Unaccounted Sink for CO2 Open
Achieving international climate goals will likely require large-scale removal of carbon dioxide from the atmosphere 1. A promising means of carbon dioxide removal (CDR) is by enhanced weathering and carbonation of various alkaline industri…

Building materials could store more than 16 billion tonnes of CO <sub>2</sub> annually Open
Achieving net-zero greenhouse gas emissions likely entails not only lowering emissions but also deploying carbon dioxide (CO 2 ) removal technologies. We explored the annual potential to store CO 2 in building materials. We found that full…

Country-Level Distribution of Trillions of Dollars in Future Climate Damages from Current Annual Emissions Open
Carbon dioxide emitted in one country affects the global climate, imposing climate damage on other countries. Here, we estimate the present value of country-to-country climate damage from current emissions using country-specific social cos…

Carbon dioxide removal could perpetuate community-scale inequalities of U.S. air pollution in net-zero scenarios Open
Pathways to net-zero reduce GHG emissions and improve air quality, but the magnitude and distribution of these improvements will depend on specific mitigation decisions, such as the amount of carbon dioxide removals (CDR). Here, we combine…

Unraveling climate change-induced compound low-solar-low-wind extremes in China Open
China's pursuit of carbon neutrality targets hinges on a profound shift towards low-carbon energy, primarily reliant on intermittent and variable, yet crucial, solar and wind power sources. In particular, low-solar-low-wind (LSLW) compound…
