Interactive map depicts global CO2 emissions

The new IEA Energy Atlas offers panoramas on every aspect of energy on a global basis and for 138 individual countries, with interactive maps and customisable charts that detail and compare a host of data based on the Agency’s authoritative statistics. Available on the IEA website’s statistics area, the Energy Atlas provides its wealth of data in 40 varying map views across eight topics: electricity and four fuels – coal, natural gas, oil and renewables – as well as energy balances and indicators plus CO2 emissions from fuel combustion, all for every year from 1973 through 2012. “Last year the IEA launched an animated Sankey flow representation of the evolution of the energy balance of countries over the last 40 years,” explained Jean-Yves Garnier, Head of the IEA Energy Data Centre, which produced the atlas. “We received a lot of compliments from policy makers, analysts and the public, but we also had many requests for more visualisation, including mapping of the world energy situation and the possibility of comparing countries. The Energy Atlas is an attempt to help everyone to better understand the complex world of energy.” On the webpage for each of the eight topics, a world map graphically illustrates ...

Low carbon shipping – A systems approach

The Low Carbon Shipping - A Systems Approach Final Report 2014 presents the key findings from each of the work packages of the LCS project that was funded by the Research Councils UK energy programme. The work undertaken in this project contributes towards an understanding of what the possible future trajectories of the industry will mean to the shipping system and the ships that service future transport demand. Operations for Low Carbon Shipping Crew Awareness A questionnaire was designed, distributed and analysed to identify the levels of seafarers’ awareness, knowledge, motivation and ideas about carbon emissions, their reduction, and methods for achieving energy efficiency on board. Key findings were: Only 20% of participants have learnt about carbon emissions and their effects via an education or training course and the most common sources for knowledge acquisition are not technical or focused: there are clear education and training needs; There is a lack of awareness and focus towards energy efficient operation and a lack of consistent knowledge about best practice; There is a clear correlation between how much participants know about carbon emissions and the energy efficient efforts they make, and so there is a real benefit in increasing knowledge; There is a ...

ICS: Shipping, World Trade and the Reduction of CO2 Emissions

The international shipping industry is firmly committed to playing its part in reducing emissions of CO2 and other Green House Gases. ICS has issued a special brochure to coincide with the UNFCCC Climate Change Conference in Lima (COP 20) which started on December 1st in Lima, explaining the issues involved and the progress being made by the industry and its global regulator - the IMO - to reduce ships’ CO2 emissions. ICS emphasises that any decision on whether to develop a Market Based Measure for shipping that might be linked to the Green Climate Fund (GCF), should be a matter for International Maritime Organization (IMO) member states. ICS says that IMO will be best placed to develop an approach that can reconcile the UNFCCC principle of ‘Common But Differentiated Responsibility (CBDR)’ – whereby developing countries are treated differently – with the need for all ships, regardless of flag, to be treated in a uniform manner. ICS emphasises that shipping is a global industry requiring rules on CO2 to be applied on a global basis to all ships. Apart from preventing market distortion in this totally globalised sector, this is necessary to avoid ‘carbon leakage’ since only about 35% of the world fleet ...

Prevention and Control of Shipping and Port Emissions in China

China is home to seven of the world's ten busiest container ports. About 26 percent of the world's containers pass through the top ten Chinese ports every year. Every ship and truck brings pollution along with its cargo, and China is paying a high price for pollution from shipping. In 2010 the country saw an estimated 1.2 million premature deaths caused by ambient air pollution. According to studies conducted in Hong Kong and Shenzhen, shipping is a significant source of these air pollution and health problems, particularly in port cities. Since Chinese port cities are among the most densely populated with the busiest ports in the world, air pollution from ships and port activities likely contributes to much higher public health risks than are found in other port regions.  Please click at table below to view the t op 20 container terminals and their throughput for 2013 (source: NRDC)    Health and Environmental Impacts of Shipping and Port Emissions Most ships at Chinese ports run on bunker fuel, also known as residual fuel. Almost all port vehicles and equipment are powered by diesel fuel. The exhaust from all of these engines contains high levels of diesel particulate matter (PM), oxides ...
