Penny stocks: 7 AIM listed green energy options to look at


  • The UK has made tackling climate change a priority and has set ambitious net zero targets.
  • Also, the London Stock Exchange’s green economy mark is a recently launched label identifying companies that are aiding in developing the green economy.
  • Penny stock investors can explore green energy focused stocks due to their high growth potential.

As the world grapples with the reality of climate change, it has become an ever more pressing challenge to address it in an urgent and immediate manner across all industries and stakeholders levels. The UK, in particular has made tackling the climate challenge a priority and has set an ambitious target of achieving net zero carbon emissions by 2050.

The UK is also set to host the COP 26 UN climate talks in Glasgow, later in the year. In keeping with this overall UK mandate, the London Stock Exchange (LSE) launched the Green Economy Mark in 2019 to spotlight diverse funds and businesses working in the sustainability sector.

All those organisations that have at least 50 per cent or more of their revenues being generated from activities benefiting the global green economy are awarded this label. Green economy mark issuers have a combine market capitalisation of over £148 billion on the LSE.

Investors considering penny stock investing can explore the green energy sector with its growing growth potential.
