M&S turns to biogas for renewable revolution

Marks & Spencer (M&S;) has agreed a landmark deal with a major biogas plant operator for the purchase of biomethane certificates which will reduce the retailer's carbon footprint by more than 6,400 tonnes. The deal, struck today (8 September) with Future Biogas, sees M&S; purchase 35,000 Mega-Watt hours (Mwh) of …

The state of greenhouse gases in the atmosphere based on global observations through 2013

The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This is according to the World Meteorological Organization’s annual Greenhouse Gas Bulletin, which injected even greater urgency into the need for concerted international action against accelerating …

Insa urges policy makers to take action against climate change, presents their climate study

In the run up to the UN climate summit in New York, Indian scientists and the Indian National Science Academy (Insa) urged policy makers to take "actionable steps" to reduce the impact of climate change. At an interaction organized at Indian Institute of Technology (IIT) Bombay on Saturday, scientists and …

Global market integration increases likelihood that a future African Green Revolution could increase crop land use and CO2 emissions

Agriculture is a key driver of tropical deforestation, and there is heated debate about whether productivity-enhancing crop innovations can slow such environmental degradation. For fixed food demand, globally higher yields will reduce cropland and hence deforestation. However, regional innovations often boost agricultural profitability and lower prices, thereby leading to cropland …

Europe Must Choose Jobs or Climate as Steel Towns Wither

U.K. lawmaker Ian Swales has already watched one steel plant close in his district, and he never wants to see it again. It felt like a funeral, he said, when plunging demand led the Redcar blast furnace in northern England to shut its doors in 2010. The memory has Swales …

Carbon Credits Give $664 Benefits Per Ton, Imperial Says

Carbon-reduction projects generate benefits beyond climate protection of about $664 per metric ton of emissions, according to an Imperial College London University survey. The study into 59 projects showed they bring ecosystem gains including soil protection, water regulation and biodiversity conservation, the university said. The survey’s estimate compares with an …

Steel Towns Threatened by EU Fight Against Climate Change

U.K. lawmaker Ian Swales has already watched one steel plant close in his district, and he never wants to see it again. It felt like a funeral, he said, when plunging demand led the Redcar blast furnace in northern England to shut its doors in 2010. The memory has Swales …

China and Indian Leaders Said to Skip UN Climate Summit

The top leaders of China and India aren’t planning to attend this month’s United Nations summit on climate change, signaling tepid support for a global pact to cut greenhouse gases among two of the largest emitters. President Xi Jinping of China and Indian Prime Minister Narendra Modi have told UN …

Australian emissions rise after carbon tax repeal -report

Carbon emissions and electricity demand in Australia have risen in the two months since the government repealed a tax on emissions, bucking a nearly six-year long trend of decline, an energy consultancy said on Thursday. Consultancy Pitt & Sherry, which tracks electricity use and emissions in Australia's National Electricity Market …

Warning over vulnerability of soil carbon to warming

The huge stores of carbon locked in the world's soils are more vulnerable to rising temperatures than previously thought. Researchers found that microbes in the soil were more likely to enhance the release of CO2 in a warming world. Soils from colder regions and those with greater amounts of carbon …

CSIRO almost 100% sure humans causing temperatures to rise

The chances that humans are not responsible for the rise in average temperatures are less than 1 in 100,000. What are the chances the world could clock up 353 consecutive months with average temperatures higher than the norm of the 20th century without humans being responsible? CSIRO's now-defunct climate adaptation …

Temperature sensitivity of soil respiration rates enhanced by microbial community response

oils store about four times as much carbon as plant biomass, and soil microbial respiration releases about 60 petagrams of carbon per year to the atmosphere as carbon dioxide. Short-term experiments have shown that soil microbial respiration increases exponentially with temperature. This information has been incorporated into soil carbon and …

Producing more grain with lower environmental costs

Agriculture faces great challenges to ensure global food security by increasing yields while reducing environmental costs. Here we address this challenge by conducting a total of 153 site-year field experiments covering the main agro-ecological areas for rice, wheat and maize production in China. A set of integrated soil–crop system management …

Unlocking the hidden value of carbon offsetting

New research demonstrates that for every one tonne of CO2 emissions removed from the atmosphere through carbon offsetting, a further $664 of value is delivered in economic, social and environmental benefits to local communities around the world. The research was conducted by Imperial College London in partnership with the International …

Tetra Pak 'making steady progress' towards recycling target

Tetra Pak needs to double recycling rates in order to hit a target of 40% of used beverage cartons being fully recycled by 2020, according to the packaging giant's latest sustainability report. The report also explains that Tetra Pak will need to triple the number of recycled cartons, to about …

System on way to cap carbon output

China will gradually set up a mechanism for limiting its overall carbon emissions and accelerate development of a national carbon market, according to the country's chief climate change negotiator. The country cut carbon dioxide emissions per unit of GDP by 28.56 percent last year compared with 2005, said Xie Zhenhua, …

A global high shift scenario: impacts and potential for more public transport, walking, and cycling with lower car use

This new report released by the University of California, Davis, and the Institute for Transportation and Development Policy (ITDP) shows that getting away from" “car – centric” development will cut urban CO2 dramatically and also reduce costs especially in the fast developing countries – India and China. This report is …

Time to act - to reduce short-lived climate pollutants

The Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants (CCAC) has released a report, titled ‘Time to Act – To reduce short-lived climate pollutants (SLCPs).' The report details the causes and sources of SLCPs, and outlines the potential benefits of control measures. According to the report, SLCPs are …

What impact can local economic development in cities have on global GHG emissions?: assessing the evidence

This paper, a contribution to the New Climate Economy project, examines how cities’ economic development strategies are likely to affect global greenhouse gas (GHG) emissions. City governments are increasingly taking an active role in economic development, working to attract and retain businesses. Urban leaders around the world have different resources, …

Japan’s medium- and long-term GHG mitigation pathways under the carbon budget approach

This paper assessed Japan’s fair carbon budget consistent with the 2 °C target between 1990 and 2100 under three frequently referred effort-sharing approaches: Converging Per Capita Emissions (CPE); Common but Differentiated Convergence (CDC); and Greenhouse Development Rights (GDRs), as well as the consequent GHG emission pathways up to 2100 for …
