Climate change can still be overcome, but only if people are willing to accept major changes in the way we live, the report said.
The authors have compiled a list of the best ways for people to reduce their carbon footprint.
The response to the Kovid-1
And the report adds that government priorities need to be rearranged.
Protecting the planet should be the first responsibility of all decision-makers, researchers say.
The authors urge the public to contribute by adopting measures to reduce carbon emissions in the report, which is based on an analysis of 7,000 other studies.
At the top of the list are living without cars, which saves an average of 2.04 tons of CO2 equivalent per person per year.
This is followed by driving an electric car with a battery – 1.95 tonnes of CO2 equivalent per person per year – and making one less long flight each year – 1.68 tonnes of CO2 equivalent per person.
Switching to a vegan diet will help – but less than dealing with transportation, research shows.
He says popular activities like recycling are worth it, but don’t reduce emissions so much.
Change of thinking
Lead author Dr. Diana Ivanova of the University of Leeds told BBC News: “We need a complete change in thinking.
“We have to agree on how much carbon we can release within what the planet can bear – then make a good living within those limits.
“The top 10 options are available to us now, without the need for controversial and expensive new technologies.”
Dr Ivanova said the blockade of the coronavirus had shown that many people could live without cars if public transport, walking and cycling were improved.
Her research highlights wealthy people who usually take more flights, drive bigger cars and consume the most.
She said: “The whole world is suffering from climate change, but this is not an ordinary person who flies regularly – this is a small group, but aviation is not taxed. This is a moral issue. “
In its league table, the purchase of renewable energy and the use of public transport rank fourth and fifth.
Sixth is the insulation of your home well, which saves 0.895 tons of CO2 equivalent.
Seventh is the transition to a vegan diet that saves 0.8 tons.
Other top actions are the use of heat pumps; transition from polluting stoves (in developing countries) to better methods of cooking and heating renewable energy buildings.
Dr. Ivanova said that if people implemented the measures, it would save about nine tons of carbon dioxide (CO2e) equivalent per person per year.
Current annual emissions from households are around 10 tonnes in the UK and 17 in the US.
The study, published recently in the journal Environmental Research Letters, says the following is useful but less beneficial to the climate: green roofs; use less paper; buying more durable items; switching off the thermostat – and recycling, which saves 0.01 tons of CO2 equivalent per year, according to Dr. Ivanova.
Some of the findings will be called into question. Surveys suggest that some people believe that climate is as important as the virus, but some do not.
Professor Tommy Widman of the University of New South Wales in Australia said: “This is a valuable study. But he considers only the carbon footprint and not other impacts such as water scarcity due to lithium extraction for electric car batteries.
Libby Peak of the Green Alliance’s expert center told BBC News: “People should not stop good habits such as recycling, which saves little carbon while preventing waste and conserving resources.”
“Better design allows people to buy less but better quality things and live in buildings with lower carbon footprints. These savings are not necessarily covered by this study. ”
