In a letter, 44 firms, including Allianz, Handelsbanken, Aberdeen Investment and Aegon NV, said a law would give investors more confidence to make long-term decisions on environmentally responsible projects. The move showcases investors' increased focus on climate change, both as a risk and an opportunity. Quoting the "catastrophic" impact of ignoring the issue, the group said uncontrolled climate change could cost the global economy $23 trillion. "Conversely, greater action on climate change could deliver $26 trillion in global economic benefit by 2030," the letter, released Friday, said.

A law would force all member states to achieve climate neutrality by 2050. Ursula von der Leyen, the new president of the European Union's executive Commission, has made combating climate change one of her top priorities. She has unveiled a "Sustainable Europe Investment Plan" which would support one trillion euros in investment over the next decade, and pledged to turn the 2050 target, something that will require a near-complete phasing-out of fossil fuels, into the "first European Climate Law."
