(CNN) -- Air miles programs should be banned and a levy on frequent flyers implemented in order to reduce carbon emissions from aviation, according to new research.The measure is one of a number of recommendations from Richard Carmichael at Imperial College London, who published a report Thursday on how the UK can meet its target of net-zero carbon emissions by 2050.Carmichael carried out his report for the Committee on Climate Change (CCC), an independent body that advises the UK government, which has previously said the country needed to become carbon-neutral by 2050 in order to fulfill its obligations under the Paris Agreement on climate change.The UK later became the first major economy to legally commit to the target. This report does not represent CCC's recommendations."Flying is a uniquely high-impact activity and is the quickest and cheapest way for a consumer to increase their carbon footprint," the report says.Air miles programs encourage people to take extra flights to keep up their "privileged traveler status" and should be banned, according to the report.So-called "mileage runs" are a common way for travelers to top up their points in order to maintain access to perks such as priority boarding.An air miles levy would be based on the number of miles flown by each passenger, penalizing those who fly the most while leaving the majority of people unaffected.Research shows that 15% of the UK population take 70% of flights, and these travelers -- who tend to be wealthier and less price-sensitive -- would shoulder most of the burden. By way of comparison, 50% of Britons don't fly at all in any one year.The levy would also encourage short-haul flights rather than more damaging long-haul flights, shift demand from planes to trains, and raise money that could be used to fund research into low-carbon aviation technology, the report said."Given the scope for frequent flyers to have carbon footprints many times that of the average UK household, a lack of policy in this area is likely to be increasingly seen as inconsistent and unjust and risks damaging public engagement with climate action," the report reads.While the report pushes for government policies to tackle emissions, private initiatives have already sprung up.Last week, International Airlines Group (IAG) -- which includes British Airways, Aer Lingus and Iberia -- promised to remove or offset all carbon emissions from its fleet of more than 570 aircraft by 2050.IAG said it would replace older aircraft, invest in sustainable jet fuel and develop technology that removes CO2 from the atmosphere.And some employers have signed up to a program that grants extra paid leave for staff who travel by train rather than plane.Climate Perks is an organization that works to encourage people to cut their carbon footprint by traveling by train without sacrificing their vacation time.This story has been updated to clarify the authorship of the report. It was researched and published by Richard Carmichael at Imperial College London for the Committee on Climate Change. 3070

Wrapping Christmas presents can be time-consuming, but there are some tricks to get it done faster, so you can focus on enjoying the holiday season. It’s common to cut wrapping paper too short or to not have enough paper left to wrap a gift. Giftwrapping expect Kammy Witulski says don’t throw it out. Instead, turn the gift sideways and you should be able to wrap with no issues. If you don’t have wrapping paper or if it’s too expensive, Witulski says there’s nothing wrong with using tissue paper. “Tissue paper comes in really nice packaging these days,” said Witulski. “You can get multiple designs in one package for just a few dollars. And it's usually between 20 to 30 sheets per package and that's plenty for you to do a lot of giftwrapping."However, you’ll need to remember to use two to three sheets, so you don’t see the gift and the tissue doesn't rip. Soft items like clothes can be hard to wrap, especially if you don’t have a box. Witulski suggests using two sheets of tissue. Roll the item, place it on the tissue and then start to roll up the clothes into the tissue, making it look like a piece of candy. Use ribbon to tie the ends, and it's the perfect little Christmas treat.Lastly, if the edges of your presents look a little wonky because the they're not crisp and clean, Witulski says to hide your lack of wrapping skills by using double sided tape, so nobody will notice mismatched folds. 1425
