The Prince of Wales is encouraging companies to sign up to the Cerrado manifesto, which aims to protect globally important natural landscapes

The loss of rainforest in the Amazon has been a familiar cause for activism for more than 30 years, but the partial success of efforts to protect it is moving the spotlight to a new landscape: Brazil’s cerrado.

Environmentalists fear that measures to reduce the exploitation of the Amazon rainforest for commodities such as soy and beef have pushed some of those activities into formerly less exploited regions such as the cerrado, a vast tropical savannah covering more than 2m sq km.

Exclusive: researchers calculated the total lifecycle emissions of an electric car, including its manufacture, battery manufacture, and all of its energy consumption

Electric cars emit significantly less greenhouse gases over their lifetimes than diesel engines even when they are powered by the most carbon intensive energy, a new report has found.

In Poland, which uses high volumes of coal, electric vehicles produced a quarter less emissions than diesels when put through a full lifecycle modelling study by Belgium’s VUB University.

While almost all companies have plans in place to reduce carbon emissions, those plans don’t go far enough, according to the Carbon Disclosure Project

Nearly nine out of 10 of the world’s biggest companies have plans in place to reduce carbon emissions, new research has found, but only a fifth of them are doing so for 2030 and beyond.

The Carbon Disclosure Project (CDP) also found that only 14% of its sample of 1,073 large companies around the world had “science-based targets” – that is, goals to reduce carbon emissions which are in line with the global agreement to hold warming to no more than 2C, enshrined in the 2015 Paris agreement.

Analysis of US fracking sites suggests pollutants including airborne particulates and heavy metals could affect neurodevelopment of babies and children

Pollutants released during fracking processes could pose a health risk to infants and children, according to researchers studying chemicals involved in shale gas operations.

The extraction of shale gas using pressurised fluid – a process known as fracking – has been used commercially since the 1950s and in recent years has fuelled an energy boom in the US. Many countries around the world are looking to follow suit – including Australia and the UK, where the first drilling in six years is expected to begin this week in the North Yorkshire village of Kirby Misperton, despite staunch opposition from protesters.
