Renewables 2024 global status report: global overview
This overview sets the scene for the various modules in the Renewables 2024 Global Status Report Collection. It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …Putting CO2 to use: creating value from emissions
New opportunities to use carbon dioxide (CO2) in the development of products and services are capturing the attention of governments, industry and the investment community. Climate change mitigation is the primary driver for this increased interest, but other factors include technology leadership and supporting a circular economy. This analysis considers …Exposure to excessive heat and impacts on labour productivity linked to cumulative CO2 emissions
Cumulative CO2 emissions are a robust predictor of mean temperature increase. However, many societal impacts are driven by exposure to extreme weather conditions. Here, we show that cumulative emissions can be robustly linked to regional changes of a heat exposure indicator, as well as the resulting socioeconomic impacts associated with …Bringing embodied carbon upfront: coordinated action for the building and construction sector to tackle embodied carbon
The World Green Building Council’s pioneering report "Bringing Embodied Carbon Upfront: Coordinated action for the building and construction sector to tackle embodied carbon" demands radical cross-sector coordination to revolutionise the buildings and construction sector towards a net zero future, and tackle embodied carbon emissions. Through the Advancing Net Zero project, …Natural climate solutions: the business perspective
The World Business Council for Sustainable Development (WBCSD) and the Nature4Climate (N4C) coalition launched “Natural climate solutions: the business perspective”, a guide to natural climate solutions for the private sector. The report, developed by WBCSD member companies and international NGOs active in this area, highlights the role that nature can …United in science: high-level synthesis report of latest climate science information convened by the Science Advisory Group of the UN Climate Action Summit 2019
The United in Science Report has been created by the world’s leading climate science organizations who have joined forces to produce a unified assessment in preparation for the United Nations Climate Action Summit. The report underlines the glaring and growing gaps between agreed on targets to tackle global warming and …Vulnerability of existing and planned coal-fired power plants in Developing Asia to changes in climate and water resources
Coal power generation dominates electricity supply in Developing Asia, and more than 400 gigawatts (GW) of new coal-fired capacity is planned for operation by 2030. Past studies on thermal electricitywater nexus have not accounted for this new capacity, and use coarse spatial and temporal resolutions in the assessment of long-term …Meeting the 1.5°C ambition: moving from incremental to exponential action
The second in its series, the 2019 Exponential Roadmap is complemented with a high-ambition narrative, Meeting the 1.5°C Ambition, that presents why the world must aim to hold global average temperature increase to just 1.5°C. Each new roadmap updates solutions that have proven potential to scale and charts progress towards …CO2 emissions from commercial aviation, 2018
This working paper details and analyzes a global, transparent, and geographically allocated carbon dioxide emissions inventory for commercial aviation for calendar year 2018. It aids policymakers, who cannot currently determine the precise amount of emissions associated with flights departing from an individual country, nor can they distinguish the proportion of …The heat is on: taking stock of global climate ambition
Vulnerable developing countries lead world on climate ambition: UN report. Developing countries are leading the world in responding to climate change, according to a new report which calls for bold, urgent action to limit the impacts of global warming. At least 112 countries, including many of those most vulnerable to …U.S. domestic airline fuel-efficiency ranking 2017-2018
This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%. The net result was a …Scaling up climate action: key opportunities for transitioning to a zero emissions society
Argentina has shown many positive developments in the climate space since 2015, but Argentina’s climate commitment in 2030 is not consistent with holding warming below 2°C, let alone limiting it to 1.5°C as required to achieve the Paris Agreement. This report, the third country assessment in the Climate Action Tracker's …Health care’s climate footprint: how the health sector contributes to the global climate crisis and opportunities for action
New report provides first-ever estimate of health care’s global climate footprint, calls for zero emissions. If the global health care sector were a country, it would be the fifth-largest greenhouse gas emitter on the planet, according to Health care’s climate footprint: How the health sector contributes to the global climate …Mission possible: how carmakers can reach their 2021 CO2 targets and avoid fines
Reducing CO2 emissions from all new cars and accelerating the uptake of zero emission models is essential to prevent a climate emergency. This is not a silver bullet - local and national policies need to reduce car ownership and use and promote active travel and shared mobility, which are also …Powering the cloud: how China’s internet industry can shift to renewable energy
China’s internet data center industry emitted an estimated 99 million tonnes of CO2 in 2018, new research from Greenpeace East Asia and the North China Electric Power University shows. Researchers found that increasing the sector’s renewable energy intake by 7% over the next five years would reduce carbon emissions by …For cities by cities: key takeaways for city decision makers from the IPCC 1.5°C report and summary for urban policymakers
Cities worked together to summarize the most relevant information and actionable findings related to the latest science on 1.5°C. The Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5°C was produced by IPCC scientists – at the request of nations at the adoption of the Paris …Putting a price on carbon: evaluating a carbon price and complementary policies for a 1.5° world
To achieve the Paris Agreement goals and limit global temperature rise this century to 1.5°C, the global economy must be rapidly transformed. A carbon price is needed to incorporate climate change costs into economic decision-making to significantly reduce U.S. greenhouse gas emissions, particularly in the electricity sector. However, a carbon …Neither euphoria nor despair: understanding the fall and rise of global energy-related CO2 emissions
This study examines the drivers of both the previous decline in global energy-related CO2 emissions, and their subsequent growth in recent years (in the EU, US, India and China), and argues that this trend was in neither case a good indicator of climate policy effort or effectiveness. Global emissions are …Neither euphoria nor despair: understanding the fall and rise of global energy-related CO2 emissions
This study examines the drivers of both the previous decline in global energy-related CO2 emissions, and their subsequent growth in recent years (in the EU, US, India and China), and argues that this trend was in neither case a good indicator of climate policy effort or effectiveness. Global emissions are …Opportunities to advance mitigation ambition in China: non-CO2 greenhouse gas emissions
Non–carbon dioxide (CO2) greenhouse gas (GHG) emissions are a substantial driver of climate change and have significant negative impacts on air quality, human health, and food production. In 2014, the last year with official data, non-GHG emissions in China were greater than total GHG emissions in Japan or Brazil. China’s …Under construction: hidden emissions and untapped potential of buildings for New Zealand’s 2050 zero carbon goal
Constructing and renovating New Zealand buildings between now and 2050 could pump out climate change pollution equivalent to one million cars on the road every year, a new report by New Zealand Green Building Council (NZGBC) has revealed. This figure – around three million tonnes of carbon – only includes …
