Area in Africa responsible for 1 billion tons of carbon emissions

Area in Africa responsible for 1 billion tons of carbon emissions

Science
Aug. 13 (UPI) -- New analysis of satellite data suggests between 1 and 1.5 billion tons of carbon emissions is emitted from northern tropical Africa each year. The latest research, published this week in the journal Nature Communications, suggests land use changes and drought have degraded the region's soil, leading to the release of large quantities of stored carbon. However, scientists say soil degradation alone isn't responsible for the region's carbon emissions. To identify other sources of released carbon, study authors suggest more research is necessary. Scientists quantified the land's contribution to global emissions by analyzing data collected by the Japanese Space Agency's Greenhouse Gases Observing Satellite and NASA's Orbiting Carbon Observatory. Researchers compared the sat...
Climate change: Emissions target could cost UK £1tn, warns Hammond

Climate change: Emissions target could cost UK £1tn, warns Hammond

Science
The chancellor has warned Theresa May that reducing greenhouse gas emissions to net zero by 2050 could cost the UK more than £1tn. The Financial Times reports that the PM wants to introduce the legislation to Parliament next week as "one of her most important legacies". Philip Hammond has written to her, saying it would mean less money for schools, police and hospitals. The Committee on Climate Change recommended the target in May. The BBC's assistant political editor Norman Smith said next week would see the first stage in the process of making this new target law - but any legislation would "have to wait until after Mrs May and after Brexit, so it could still be some time off". The CCC, which is the independent adviser to government on climate change, p

Air pollution: How does London’s new emissions zone compare?

Science
Media playback is unsupported on your device London's tough new Ultra Low Emissions Zone (ULEZ) is the latest - and one of the strongest - steps yet taken to limit emissions of pollutants from cars, vans and trucks. So how does it compare with other cities in Europe and the rest of the world?CAZ? LEZ? ULEZ? What do they all mean?These are all different ways of describing geographical areas of cities or towns that have placed restrictions on the use of vehicles, with the goal of tackling air pollution. A CAZ is a clean air zone, a LEZ is a low-emissions zone. Now we have London with the world's first ULEZ, or ultra-low emissions zone. In the UK, CAZs are areas that can decide to use charging as a means of cle...
Climate change: Pledge to cut emissions from dairy farms

Climate change: Pledge to cut emissions from dairy farms

Science
A dairy firm is pledging to make its operations carbon-neutral from cow to supermarket by 2050, including more than 2,000 farms in the UK. This will require "radical changes" over the coming decades, including developing new technologies, the dairy co-operative, Arla Foods, said.It admitted the target was "ambitious", but said it was achievable.However, the Vegan Society said there was no way to make dairy a climate-friendly product.Gases which help to heat the atmosphere and contribute to climate change are a by-product of the dairy industry. They include direct emissions of methane, a potent greenhouse gas, from cows, and carbon dioxide and nitrous oxide from the likes of packaging, transportation and fertilisers. Arla, the lar...

Climate change: Which airline is best for carbon emissions?

Science
EasyJet has come top of the league for airlines trying to cut carbon emissions to tackle climate change.A report suggests that by 2020 its emissions per passenger kilometre will be less than half that of some rivals.The firm's performance is partly down to its modern, efficient fleet and its push to fill every seat.Companies named as having the weakest plans to cut emissions are Air China; China Southern; Korean Air; Singapore Airlines and Turkish Airlines.EasyJet's aircraft are expected to be emitting 75g of CO2 per passenger km by 2020, compared with 172g for Korean Air.International Airlines Group (IAG), which includes British Airways, is expected to emit 112g. The industry has volunteered to freeze its overall emissions by 2020, and halve emissions by...
