Fossil fuels – coal, oil and gas – are still the biggest driver of climate change, responsible for more than three-quarters of global greenhouse gas emissions. If we’re serious about a livable planet, we need to stop funding the problem and start funding the solutions.
One powerful way to do that is by choosing fossil fuel-free investments. These are funds that exclude companies involved in fossil fuel extraction or power generation, and instead back businesses driving the shift to a cleaner economy.
Here are 10 trusted options to help you invest for a greener future. (Remember: this isn’t personal advice, and your capital is at risk.)
You can find most of these funds on major UK investment platforms, including The Big Exchange, Interactive Investor, AJ Bell, Hargreaves Lansdown, or by asking your Independent Financial Adviser.
