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 …

Over 40 Indian firms make carbon disclosures

Over 80 per cent of the 51 Indian companies responding to the Carbon Disclosure Project (CDP) India have reported one or more types of emission reduction targets and initiatives this year, a new report said on Tuesday. About 40 per cent companies are committed to renewable energy production and consumption …

Ocean acidification is deadly threat to marine life, finds eight-year study

Plastic pollution, overfishing, global warming and increased acidification from burning fossil fuels means oceans are increasingly hostile to marine life If the outlook for marine life was already looking bleak – torrents of plastic that can suffocate and starve fish, overfishing, diverse forms of human pollution that create dead zones, …

As scientists ponder “hacking the climate,” poor countries are wary

As a child during Ethiopia’s deadly famine of 1984, Asfawossen Kassaye remembers watching people from the countryside flock to his town, desperately looking for food after a drought devastated their fields. He knows first-hand how much damage climate change has done to his region of East Africa, where scientists say …

Call for vehicle testing overhaul as Australia's emissions fight moves to roads

Australia’s motoring lobby is launching a campaign for “real-world” vehicle emissions testing, arguing the current system needs an overhaul because it is misleading consumers and regulators. The Australian Automobile Association will on Monday release results from emissions and fuel consumption tests on 30 passenger and light commercial vehicles showing discrepancies …

UN shipping climate talks ‘captured’ by industry

The shipping industry has “captured” UN talks on a climate target for the sector, using its clout to delay and weaken emissions curbs. That is the conclusion of a report by business lobbying watchdog Influence Map on the International Maritime Organization (IMO). The study was released to coincide with a …

Americans want a tax on carbon pollution, but how to get one?

According to a new study published by Yale scientists in Environmental Research Letters, Americans are willing to pay a carbon tax that would increase their household energy bills by $15 per month, or about 15%, on average. This result is consistent with a survey from last year that also found …

More acidic oceans 'will affect all sea life'

All sea life will be affected because carbon dioxide emissions from modern society are making the oceans more acidic, a major new report will say. The eight-year study from more than 250 scientists finds that infant sea creatures will be especially harmed. This means the number of baby cod growing …

Fossil CO2 & GHG emissions of all world countries

Part of the Paris Agreement is the implementation of a transparency framework to be implemented bottom-up based on the national GHG emission inventories of all Parties reported to the UNFCCC. In addition, 5-yearly global stocktakes are planned from 2023 onwards to monitor emission trends and the efforts of the individual …

No one can beat climate change like nature itself: Study

Nature can provide cost-effective and permanent solutions to check climate change, so much so that it can reduce over a third (37%) of greenhouse gas emissions by 2030, a new study by scientists from global conservation organisation, The Nature Conservancy and 15 other institutions, has concluded. As per the study, …

India can reduce 520 million tonnes of greenhouse gas: Study

Merely by conservation of nature, and reforestation, about 37 percent of global greenhouse gas emission could be reduced by 2030. New Delhi/Washington: India can offset close to 520 million tonnes of greenhouse gas emissions per year through reforestation alone, according to a study. The study, released by The Nature Conservancy, …

Manufacturing a low-carbon society: how can we reduce emissions from cement and steel?

Deploying current technologies to decarbonise the steel and cement industries is unlikely to be sufficient to meet the Paris Agreement’s 1.5?C limit, according to a new Climate Action Tracker (CAT) study - "Manufacturing a low-carbon society: how can we reduce emissions from cement and steel?". The steel and cement industries …

Greenhouse gas emissions from global shipping, 2013–2015

Reducing greenhouse gas (GHG) emissions is the key to avoiding the most catastrophic impacts of climate change. Despite international shipping being excluded from the Paris Agreement, the International Maritime Organization (IMO) is developing its own strategy to reduce GHGs from ships. IMO member states will need to understand recent trends …

CO2 reduction technologies for the European car and van fleet, a 2025–2030 assessment

Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system. When the European Union (EU) introduced its …

Climate change: Warming soils may intensify Earth's temperatures, warn scientists

The analysis of the results of the study has revealed that the warm dirt has accelerated the catastrophe of global warming At a time when climate change has the world in a tight grip, a recent study has issued a warning saying that, warming soils are releasing more carbon, thus …

The risks of large-scale biosequestration in the context of Carbon Dioxide Removal

The explicit reference to “a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases” (Art. 4) in the 2015 Paris Agreement has given a strong impetus to Carbon Dioxide Removal (CDR) proposals that aim to remove greenhouse gas emissions through bioenergy and carbon capture and storage …

Carbon emissions from warming soils could trigger disastrous feedback loop

Warming soils are releasing more carbon into the atmosphere than previously thought, suggesting a potentially disastrous feedback mechanism whereby increases in global temperatures will trigger massive new carbon releases in a cycle that may be impossible to break. The increased production of carbon comes from the microbes within soils, according …

Trump EPA to propose repealing Obama's climate regulation: document

WASHINGTON (Reuters) - The U.S. Environmental Protection Agency will propose repealing the Clean Power Plan - the Obama administration’s centerpiece regulation to fight climate change - and plans to solicit input on a rule to replace it, according to an EPA document seen by Reuters. The decision marks the agency’s …

Life cycle energy consumption and greenhouse gas emissions analysis of natural gas-based distributed generation projects in China

In this paper, we used the life-cycle analysis (LCA) method to evaluate the energy consumption and greenhouse gas (GHG) emissions of natural gas (NG) distributed generation (DG) projects in China. We took the China Resources Snow Breweries (CRSB) NG DG project in Sichuan province of China as a base scenario …

Trends in global CO2 and total greenhouse gas emissions: summary of the 2017 report

Global emissions of climate-warming carbon dioxide remained static in 2016, a welcome sign that the world is making at least some progress in the battle against global warming by halting the long-term rising trend. All of the world’s biggest emitting nations, except India, saw falling or static carbon emissions due …

Climate experts criticise Scotland's greenhouse emissions cuts strategy

Climate experts have warned the Scottish government its ambitious plans to cut greenhouse gas emissions lack credibility and risk stalling unless its strategies improve dramatically. The Committee on Climate Change (CCC) said the devolved government had so far led the UK in its efforts to cut emissions, reducing its actual …
