New phase of globalisation could worsen CO2 pollution: study

Global temperatures have already risen a full degree Celsius since the mid-19th century, enough to disrupt weather patterns and boost deadly storms, droughts and floods. The shift of low-value, energy-hungry manufacturing from China and India to coal-powered economies with even lower wages could be bad news for the fight against …

Rising temperature: India is warming up rapidly

A new study on climate change in India has confirmed a rapid rise in surface temperatures in the past 70 years. The study calculated temperature rise in terms of change occurring from decade to decade, using information from two different datasets covering the period from 1951 and 2013. The temperature …

The future of cooling: opportunities for energy-efficient air conditioning

The growing use of air conditioners in homes and offices around the world will be one of the top drivers of global electricity demand over the next three decades, according to new analysis by the International Energy Agency that stresses the urgent need for policy action to improve cooling efficiency. …

The rise of South–South trade and its effect on global CO2 emissions

Economic globalization and concomitant growth in international trade since the late 1990s have profoundly reorganized global production activities and related CO2 emissions. Here we show trade among developing nations (i.e., South–South trade) has more than doubled between 2004 and 2011, which reflects a new phase of globalization. Some production activities …

Despite the surge in renewables, emission levels almost unchanged

The rise of renewable sources of energy and their gallant victories over fossil fuels — particularly coal — is now legendary. Last year, India added 11,788 MW of renewable energy capacity, twice as much as coal and hydro put together (5,400 MW). An estimate has it that 65 per cent …
