S uppose that averting dangerous climate change meant limiting the concentration of greenhouse gases (measured in parts per million, or ppm, by volume) in the atmosphere so that the world faced a temperature increase of no more than 2°C—a goal endorsed by the European Union. What would it take to meet this goal? Because of “climate uncertainty,” we cannot be sure. We can meet the goal with prob...

Numerous proposals have surfaced promoting policies to limit U.S. emissions of gases like Carbon Dioxide (CO2), a primary contributor to climate change. One such proposal is Senate Bill 2191, the Lieberman-Warner Climate Security Act, which was introduced to the 110th Congress on October 18, 2007. Like many proposals to control greenhouse gas emissions, S. 2191 embraces a market-based approach ...

BACKGROUND Climate change is a global threat to health and wellbeing. Here we provide findings of an international research project investigating the health and wellbeing impacts of policies to reduce greenhouse gas emissions in urban environments. METHODS Five European and two Chinese city authorities and partner academic organisations formed the project consortium. The methodology involved ...

JEL Classification: F16, F43 This study examines the impacts of CO2 emissions on economic growth of Vietnam for the period 1986-2015 by using Autogressive Distributed Lag (ARDL) model. The results reveal that there is cointegration relationship between CO2 emissions and economic growth. In the long run carbon dioxide emissions have a significant negative impact on Vietnam economic growth. There...

This study describes the methodology and results for calculating future global aviation emissions of carbon dioxide and oxides of nitrogen from air traffic under four of the IPCC/SRES (Intergovernmental Panel on Climate Change/Special Report on Emissions Scenarios) marker scenarios: A1B, A2, B1, and B2. In addition, a mitigation scenario has been calculated for the B1 scenario, requiring rapid ...

Affluent western individuals are increasingly fretting about the carbon dioxide emissions from their lifestyle and energy use but one key issue, having fewer children, is little considered. Nigel Williams reports.

The study provides a statistical trend analysis of different air pollutants using Mann-Kendall and Sen’s slope estimator approach on past pollutants statistics from air quality index station of Varanasi, India. Further, using autoregressive integrated moving average model, future values of air pollutant levels are predicted. Carbon monoxide, nitrogen dioxide, sulphur dioxide, particu...

Northern Hemisphere's carbon dioxide emissions. "That's much more than any terrestrial plant ecologist would have considered likely," Tans said. Conserving tree and plant populations, he added, might raise their carbon dioxide uptake even higher. Understanding how carbon cycles through plants is vital to decreasing global warming. By burning fuel and clearing forests, human activity generates 7...

The electricity sector is a major source of carbon dioxide emissions that contribute to global climate change. Switching from fossil fuels to renewable fuels such as geothermal, biomass or wind would help to reduce carbon emissions from electricity generation. This research analyzes the costs and carbon emission consequences of three policies to promote the use of renewables to generate electri...
