This overview sets the scene for the various modules in the Renewables 2024 Global Status Report Collection. It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …

Effect of water table management and elevated CO2 on radish productivity and on CH4 and CO2 fluxes from peatlands converted to agriculture

Anthropogenic activity is affecting the global climate through the release of greenhouse gases (GHGs) e.g. CO2 and CH4. About a third of anthropogenic GHGs are produced from agriculture, including livestock farming and horticulture. A large proportion of the UK's horticultural farming takes place on drained lowland peatlands, which are a …

Proton pumping accompanies calcification in foraminifera

Ongoing ocean acidification is widely reported to reduce the ability of calcifying marine organisms to produce their shells and skeletons. Whereas increased dissolution due to acidification is a largely inorganic process, strong organismal control over biomineralization influences calcification and hence complicates predicting the response of marine calcifyers. Here we show …

Impacts of world class vehicle efficiency and emissions regulations in select G20 countries

In 2014, the G20 Energy Efficiency Action Plan prioritized the establishment of a Transport Task Group (TTG) to promote cooperation among participating G20 countries to develop domestic policies that improve the energy efficiency and environmental performance of motor vehicles, particularly heavy-duty vehicles. Led by the United States, the TTG currently …

BP Energy Outlook 2017

According to this report, India’s consumption growth of fossil fuels will be the highest by 2035 and it will overtake China as the largest growth market for energy in volume terms by 2030. Global demand for oil will still be growing in 2035 even with an enormous growth in electric …

A comparison of contracts for difference versus traditional financing schemes to support ultralow-carbon fuel production in California

Develops a cost-benefit analysis to compare the impact of three separate policies to spur the additional production of ultralow-carbon fuels in California: a contract-for difference price guarantee, a per-gallon subsidy, and upfront capital grants. Uses a cashflow model to estimate the amount of new production of qualifying fuels in California …

Commercial transport in urban areas

The presence of commercial transport in our cities has steadily grown over recent years. Commercial transport seems today indispensable, especially in downtown areas, as it ensures that goods and services reach the local population, organizes public services such as waste removal and thus contributes to economic life. Thereby commercial transport …

Earth breaks heat record in 2016 for third year in a row

Taking a global average of the land and sea surface temperatures for the entire year, NOAA found the data for "2016 was the highest since record keeping began in 1880," said the announcement. Last year, the Earth sweltered under the hottest temperatures in modern times for the third year in …

Infosys announces internal carbon pricing, to aid in reducing emissions

The idea behind deciding an internal carbon price is essentially that the entity polluting should pay for the damage done to the environment. Indian multinational company Infosys Monday announced its internal carbon price at $10.5 per ton of Carbon Dioxide equivalent (CO2e) emission. This price, which will be valid for …

Ready for CCS retrofit: the potential for equipping China’s existing coal fleet with carbon capture and storage

China currently has around 900 GW of installed coal-fired power capacity, representing potential emissions of 85 billion tonnes of CO2 if these plants continue to operate at current levels. Meanwhile under the global climate negotiations, China has committed to peaking its CO2 emissions by 2030. The enduring emissions from China’s …

Cost-competitive renewable power generation: potential across South East Europe

Renewable energy has long been used in South East Europe, whether as fuelwood for heating or in the form of hydroelectric power generation. More recently, governments from Slovenia to Ukraine have pledged to shift to renewables to replace ageing fossil-based energy installations and reduce carbon-dioxide emissions. Clean, sustainable power sources …

Transforming Africa’s transport sector with the implementation of Intended Nationally Determined Contributions

The Intended Nationally Determined Contributions (INDCs) herald a new phase in the global commitment to achieve climate resilience. Fifty three countries in Africa submitted their contributions on the bases of their national development priorities, capabilities and circumstances. Collectively, the INDCs map Africa’s contribution to the goal of the Paris Agreement …

Hydroclimate changes across the Amazon lowlands over the past 45,000 years

Reconstructing the history of tropical hydroclimates has been difficult, particularly for the Amazon basin—one of Earth’s major centres of deep atmospheric convection. For example, whether the Amazon basin was substantially drier or remained wet during glacial times has been controversial, largely because most study sites have been located on the …

International comparison of light-duty vehicle fuel economy 2005-2015: ten years of fuel economy benchmarking

While the average fuel economy of vehicles continues to improve, a new analysis by the Global Fuel Economy Initiative (GFEI) highlights that the rate of progress has slowed in recent years. The average amount of fuel required to travel 100 km improved by 1.1% in 2014 and 2015, down from …

January follows December trend of bad air days

The Millennium City saw an unprecedented spike in the CO (carbon monoxide) level on Wednesday and Thursday, possibly due to the dip in temperature and increased vehicular movement on the national highway. While the CO level touched the 70 mg per cubic metre mark on Wednesday, 17 times higher than …

Comparing estimates of climate change impacts from process-based and statistical crop models

Attempts to measure the impacts of climate change on agriculture must invariably rely on models that translate changes in climate to changes in agricultural outcomes. This need for models exists even when assessing the impacts of climate trends that have already occurred, since simultaneous changes in other factors that affect …

Air pollution level in Kolkata among country's highest

KOLKATA: New Delhi may be reeling under severe air pollution, but Kolkata has not only touched the country's capital city but have also surpassed the city quite a few days in terms of air pollution. A joint study by the British Deputy High Commission, UKAID and Kolkata Municipal Corporation that …

2017 Outlook for Energy: A View to 2040

The share of the world's electricity generated by coal is expected to fall to about 30 percent from approximately 40 percent in 2015 as the use of lower-emission energy sources including natural gas, nuclear and renewables increases says this report. Global population growth of nearly 2 billion, a doubling of …

Effect of government subsidies for upstream oil infrastructure on U.S. oil production and global CO2 emissions

The United States now produces as much crude oil as ever – over 3.4 billion barrels in 2015, just shy of the 3.5 billion record set in 1970. Indeed, the U.S. has become the world’s No. 1 oil and gas producer. The oil production boom has been aided by tax …

The economic impacts of the clean power plan: how studies of the same regulation can produce such different results

Various organizations have published forecasts of the economic impacts of the Clean Power Plan (CPP), EPA’s regulation that limits carbon dioxide emissions from power plants, with studies arriving at markedly different conclusions about the effect of the policy on electricity affordability and the overall economy. In this working paper, WRI …
