This paper discusses the CO2 footprint of California’s drought during 2012–2014. The authors show that California drought significantly increased CO2 emissions of the energy sector by around 22 million metric tons, indicating 33% increase in the annual CO2 emissions compared to pre-drought conditions. They argue that CO2 emission of climate extremes deserve more attention, because their cumulative impacts on CO2 emissions are staggering. Most countries, including the United States, do not have a comprehensive a nationwide energy-water plan to minimize their CO2 emissions, therefore the authors argue that developing a national water-energy plan under a changing climate should be prioritized in the coming years.
This paper uses ‘Medieval’ drought conditions from the 12th Century to simulate the implications of severe and persistent drought for the future of water resource management in metropolitan Phoenix, one of the largest and fastest growing urban areas in the southwestern USA. Anticipatory models enable long-term policy analysis for climate change. Mega-drought results in unsustainable groundwater use between 2000 and 2060. Aggressive drought management policies can produce sustainable yield. The time to manage droughts is before they occur. This relates to SDG 6, SDG 11 and SDG 13.
This report offers a framework for principle-based collaboration between business, the UN, governments, civil society and other stakeholders in relation to soil management and the entire agricultural value chain. It directly supports SDG 2 and SDG 15.
This report highlights the benefits for businesses of implementing adaptation activities that contribute to increasing societal resilience and attaining Goal 15.
Linking to Goals Goal 2, 6, 12, 15, 17, these guidelines respond to the integrity challenges facing water stewardship initiatives (WSIs). Access quality management processes and a suite of practical tools via the questions and practical framework below in order to ensure high levels of integrity and transparency in your WSI.
To advance Goal 6, this report recommends good practices for developing water stewardship initiatives in an inclusive and transparent manner that ensures sustainable water management.
The Business Leadership Criteria on Carbon Pricing is designed to inspire companies to reach the next level of climate performance and to advocate for a price on carbon as a necessary and effective measure to tackle the climate change challenge. This report links to Goals 12, 13, 14, and 15.
Linking to Goals 12, 13, 14, and 15, this report sets baseline expectations for companies to provide proactive and constructive input to Governments to advocate for the creation of effective climate policies.
