DAVOS, Switzerland, Jan 20 (Reuters) - Climate activists

sprayed green paint over Amazon's ( AMZN ) base in Davos on

Monday and disrupted helicopter landings at the start of the

World Economic Forum's annual meeting.

Swiss police swarmed to close down both protests as global

business and political leaders descended on the mountain resort

on the opening day of the meeting, where demonstrations over

fossil fuels and climate change have become a regular feature.

Demonstrators protesting over fossil fuel subsidies daubed

orange symbols on the shop front where Amazon ( AMZN ) has set up a

temporary base on the main street in Davos, as well as

splattering green paint over the plate-glass windows.

Greenpeace, which briefly blocked the heliport in Davos,

said in a statement that it had taken the action to call for "a

fair tax on the richest people, to fund environmental protection

and invest in a fair and sustainable future for humanity".

Police moved in to remove around 10 protesters who were

blocking two vehicles at the heliport entrance with bright

yellow banners saying "TaxTheSuperRich".

"So far we have blocked 10-20 helicopters in one and a half

hours. Over the course of the day we are expecting around a

hundred helicopters arriving here," Greenpeace activist Clara

Thomson told Reuters.

High-profile politicians and business leaders often use the

helicopter pad to land in the Swiss Alpine resort. Security is

tight for the WEF meeting, where one of the main themes for

discussion this week is "safeguarding the planet".

The WEF said on its 2025 programme that it is "crucial for

businesses, governments, and civil society to work together to

find common solutions and take decisive action".
