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 …

Lessons from a decade of emissions gap assessments

To mark ten years of the Emissions Gap Report, and inform the Climate Action Summit, UNEP released Lessons from a decade of emissions gap assessments. The report finds that the last ten years have, in some ways, been a lost decade of climate action. Greenhouse gas emissions have only grown, …

The global climate in 2015-2019

The tell-tale signs and impacts of climate change – such as sea level rise, ice loss and extreme weather – increased during 2015-2019, which is set to be the warmest five-year period on record, according to the World Meteorological Organization (WMO). Greenhouse gas concentrations in the atmosphere have also increased …

Bridging the gap: enhancing mitigation ambition and action at G20 level and globally

As the world strives to cut greenhouse gas emissions to meet the temperature targets of the Paris Agreement, in so doing limiting the worst impacts of climate change, it is crucial to track progress. Only by knowing where countries are going compared to where they should be, can build pressure …

Exponential roadmap: scaling 36 solutions to halve emissions by 2030

Greenhouse gas emissions could be halved in the next decade if a small number of current technologies and behavioural trends are ramped up and adopted more widely, researchers have found, saying strong civil society movements are needed to drive such change. Solar and wind power, now cheaper than fossil fuels …

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 …

A critique of lifecycle emissions modeling in “the greenhouse gas benefits of corn ethanol— assessing recent evidence”

Although recently published research addresses a range of issues relating to the corn ethanol lifecycle, much attention has focused on the result that corn ethanol production has a significantly better emissions profile than the U.S. Environmental Protection Agency (EPA) concluded in its 2010 regulatory impact analysis for the Renewable Fuel …

Global climate action from cities, regions and businesses – 2019

This report is the second global analysis of local and regional government and corporate climate contributions, updating “Global Climate Action from Cities, Regions, and Companies” launched at the 2018 Global Climate Action Summit. The 2018 report established the strong potential of subnational and non-state actors to help avoid climate change. …

Assessing the potential advanced alternative fuel volumes in Germany in 2030

This working paper assesses the potential for Germany to meet the transport sector targets set by the European Union's recast Renewable Energy Directive (RED II) using advanced, non-food-based fuels. Policies supporting advanced, non-food-based fuels can deliver substantial carbon savings —as much as 16 million tonnes of CO2-equivalents with high policy …

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 …

Blockchain technologies as a digital enabler for sustainable infrastructure

Embracing new technologies that could enable drastic reductions in GHG emissions will be key to delivering low-emissions pathways for growth, but it is not always obvious what the big breakthroughs will look like. This report looks at how blockchain technology can be applied to support sustainable infrastructure investment that is …

Addressing climate change in transport: Volume 1 - pathway to low-carbon transport

Climate change is set to have profound effects on Vietnam’s development. With nearly sixty percent of its land area and seventy percent of population at risk of multiple natural hazards, Vietnam globally is among the most vulnerable countries to both chronic and extreme events. At the same time, as Vietnam’s …

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 …

Uncertainty, scenario analysis, and long-term strategies: state of play and a way forward

Uncertainty is a common challenge to any long-term planning. This working paper takes stock of how long-term low-emission development strategies submitted to UNFCCC perceive and handle uncertainties, and how scenarios are used to illustrate different pathways that countries may take under uncertainty. Based on the stock-take and literature review, the …

The cost of climate change

For Global Spotlight Report, Climate Scorecard asked Country Managers to provide information on how climate change is impacting the most vulnerable population groups in the leading greenhouse gas emitting countries that cover. Extreme weather events, such as soaring temperatures, droughts, floods, and forest fires are the cause of much climate …

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 …

A possible 2050 climate target for the EU

This study assesses the EU’s 2050 target, i.e. halving global emissions by 2050 to be in line with 2°C, in today’s setting to evaluate if the target, which was set ten years ago, is still appropriate and/or sufficient. It offers recommendations for the EU to aim for more ambitious targets.
