NT were already committed not to invest in companies which were based on oil sands or thermal coal, now they're totally divesting from all fossil fuels within 3 years.
In their words
"The impacts of climate change pose the biggest long-term threat to the places we care for. We take our responsibilities towards the environment very seriously and are committed to playing our part in helping the UK achieve net zero emissions.
We will do everything we can to protect the natural environment and we’re changing our investment policy to support this.
Returns from our investments are vital for helping us protect and care for special places across the nation. They enable us to look after the natural environment and keep our membership fees affordable.
As part of our commitment to our conservation aims, we’re stopping investment in fossil fuel companies within three years. Our current investment policy requires that no investment is made directly in companies which derive more than 10 per cent of their turnover from the extraction of thermal coal or oil from oil sands. Under the new policy there will be no investment in such companies."
