Climate change: Top 10 tips to reduce carbon footprint revealed
Climate change can still be tackled but only if people are willing to embrace major shifts in the way we live, a report says. The authors have put together a list of the best ways for people to reduce their carbon footprints. The response to the Covid-19 crisis has shown that the public is willing to accept radical change if they consider it necessary, they explain. And the report adds that government priorities must be re-ordered. Protecting the planet must become the first duty of all decision-makers, the researchers argue. The authors urge the public to contribute by adopting the carbon-cutting measures in the report, which is based on an analysis of 7,000 other studies. Top of the list is living car-free, which saves an average of 2.04 tonnes of CO2 equivalent per person annually. This is followed by driving a battery electric car - 1.95 tonnes of CO2 equivalent per person annually - and taking one less long-haul flight each year - 1.68 tonnes of CO2 equivalent per person. Switching to a vegan diet will help - but less than tackling transport, the research shows. It says popular activities such as recycling are worthwhile, but dont cut emissions by as much. The lead author, Dr Diana Ivanova from Leeds University, told BBC News: We need a complete change of mindset. We have to agree how much carbon we can each emit within the limits of what the planet can bear then make good lives within those boundaries. The top 10 options are available to us now, without the need for controversial and expensive new technologies. Dr Ivanova said the coronavirus lockdown has shown that many people could live without cars if public transport, walking and cycling were improved. Her research highlights rich people who typically take more flights, drive bigger cars and consume the most. She said: All the world suffers from climate change, but its not the average person who flies regularly its a small group, yet aviation is under-taxed. Its a moral issue. In her league table, buying renewable power and using public transport rank fourth and fifth. Sixth is insulating your home well, which saves 0.895 tonnes of CO2 equivalent. Seventh is switching to a vegan diet, which saves 0.8 tonnes. Other top actions are using heat pumps; switching from polluting cookstoves (in developing countries) to better methods of cooking, and heating buildings with renewable energy. Dr Ivanova said that if people implemented the measures, it would save around nine tonnes of carbon dioxide equivalent (CO2e) per person per year. Current annual household emissions are around 10 tonnes in the UK, and 17 in the US. The study, out soon in the journal Environmental Research Letters, says the following are worthwhile, but of lesser benefit to the climate: green roofs; using less paper; buying more durable items; turning down the thermostat - and recycling, which saves 0.01 tonnes of CO2 equivalent per year, according to Dr Ivanova. Some of the findings will be questioned. Polls suggest some people think climate is as important as the virus, for instance, but some dont. Professor Tommy Wiedmann from the University of New South Wales in Australia, said: This is a valuable study. But it only looks at the carbon footprint and not at other impacts like water scarcity because of lithium mining for electric car batteries. Libby Peake, from the Green Alliance think tank, told BBC News: People shouldnt stop good habits like recycling, which saves some carbon while preventing waste and conserving resources. Better design allows people to buy fewer but higher-quality things and to live in buildings with lower carbon footprints. These savings arent necessarily covered by this study.
