Paragraph: 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.

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."
