Green certificate to ensure safer operation theatres

The anaesthetics used by a hospital contribute to global warming in the same proportion as emissions from 100 cars every year. A kilogram of anaesthetic gas produces 1,620 kg of carbon dioxide. Hospitals may have cure for people but, in a lot of ways, they are harming the environment, say …

Satellite technology crucial in monitoring greenhouse gas emissions

Satellite technology plays a crucial role in measuring greenhouse gas emissions globally, the heads of several space agencies agreed Sunday as they vowed to work together to develop a coordinated monitoring system. The pledge comes after a landmark climate accord in Paris last year at which world leaders agreed to …

ConnectKaro to turn city ideas into actions

With the second phase of the road rationing plan starting from April 15, the city is hoping that the impact on pollution levels will go beyond the cosmetics of less crowded roads. To take ideas and turn them into actionable measures is the need of the hour. That's what ConnectKaro, …

Summer in March? Warming Climate Alters Europe's Seasons

Earth’s seasonal clock is out-of-whack. Summers in Europe are coming ten days ahead of schedule, and could be up to 20 days early by century’s end if the current pace of carbon emissions continues, according to a new study by French scientists published Monday. And it’s not just Europe. Trees …

Massive carbon capture investment 'needed to slow global warming'

Carbon disposal technologies are needed because incremental emissions cuts are not enough to fight climate change, says Oxford University climate scientist Combating climate change successfully will require massive investments in technologies to capture and store carbon dioxide, new research has found. Myles Allen, professor of climate dynamics at Oxford University, …

China’s Carbon Emissions May Have Peaked, but It’s Hazy

BEIJING — A year and a half ago, negotiators from the United States persuaded the Chinese government to commit to a deadline for reversing the growth in greenhouse gas emissions from China. The Obama administration portrayed the pledge as a major victory because China produces more of the gases that …

Emissions trading schemes and their linking: challenges and opportunities in Asia and the Pacific

Asia and the Pacific has achieved rapid economic expansion in the recent years and has become a major source of greenhouse gas (GHG) emissions. With more than half of the world’s population and high rates of economic growth, the region is especially vulnerable to the effects of climate change and …

Britain's greenhouse gas emissions fell 3.3 percent in 2015 - government

Britain's greenhouse gas (GHG) emissions fell by 3.3 percent in 2015, largely due to a decline in coal-fired power generation and marking the third straight yearly drop, preliminary government data showed on Thursday. Output of the heat-trapping gases in Europe's second-largest emitter behind Germany fell to 497.2 million tonnes of …

United States, China to sign Paris climate accord on April 22

The United States and China confirmed Thursday that they will sign the Paris climate change agreement in New York on April 22, a move that officials hope will help the accord enter into force this year. The world's two biggest greenhouse gas emitters issued a joint presidential statement in which …

International comparison of fossil power efficiency and CO2 intensity

The purpose of this study is to compare the generating efficiency and CO2-intensity of fossil-fired power plants for Australia, China, France, Germany, India, Japan, Nordic countries (Denmark, Finland, Sweden and Norway aggregated), South Korea, United Kingdom and Ireland (aggregated), and the United States. This is done by calculating separate benchmark …

The tradeoffs between GHGs emissions, income inequality and productivity

Rising emission of greenhouse gasses (GHGs) and growing economic inequalities have emerged as key challenges for policymakers over the past two decades and the problems are likely to intensify in the foreseeable future. Numerous studies in the past have examined the relationship between these and implications on growth and equity …

Boreal and temperate trees show strong acclimation of respiration to warming

Acclimation of leaf respiration to a 3–5-year period of warming by 3.4 °C for 10 North American tree species in forest conditions eliminated 80% of the increase in leaf respiration expected of non-acclimated trees; this suggests that the increase in respiration rates of terrestrial plants from climate warming, and the …

Government's plan for secure power generation 'unfit for purpose': report

A £2.8bn government scheme funded by energy bill payers which aims to keep the lights on in Britain has been condemned as wasteful, expensive and “unfit for purpose” in a damning report. The claims from the Institute of Public Policy Research (IPPR) comes on the day that one of the …

China’s national emissions trading system: implications for carbon markets and trade

China’s introduction of a national ETS, scheduled for 2017, is an important development in the expanding carbon market landscape. As countries move towards implementation of the recently-adopted Paris Agreement, this sends a powerful signal about China’s mitigation commitment and support for carbon markets. As the largest emitter of greenhouse gases …

'Climate Parliament' seeks changes in MP, MLA dev fund policy

A group of lawmakers has asked the government to make some crucial policy changes in existing schemes to facilitate low carbon development work in their constituencies and said India's ambitious target of low carbon emissions can be met by local area actions by MPs. MPs and MLAs under the Climate …

'2-wheelers chief contributor to B'luru's CO2 emissions'

Commute traffic is the traffic that involves travel to the workplace and back A transnational study that analysed Carbon dioxide (CO2) emissions in Bengaluru and Xi’an in China has come to a conclusion that car availability and location of the house majorly contribute to commute CO2 missions in developing countries. …

Chinese coal data may contain irregularities, study finds

Chinese proclamations on coal consumption and the corresponding decline in carbon emissions may be off the mark, a journal study found. A recent report from the Brookings Institution stated coal use in China may have peaked and is starting to slow down as the country shifts from an economic strategy …

Probe of Exxon's climate change disclosures expands

The top attorneys from Massachusetts and the U.S. Virgin Islands said on Tuesday they will investigate whether Exxon Mobil Corp (XOM.N) misled investors and the public about the risks of climate change.
