Activists also scaled a building in the i360 complex, removed the British Airways flag, and replaced it with a banner reading "Our house is on fire."
The stunts were in protest at i360 sponsor British Airways' role both in the developing climate crisis, and in controversial deportations of UK-born citizens under the government's "hostile environment" policy.
The protesters demanded the immediate government action to combat the climate crisis and to address racial justice.
The march took place on the Brighton seafront and was attended by an estimated three hundred concerned members of the public.
The demonstration was part of a local build-up to Extinction Rebellion's "national rebellion" in London.
From Tuesday 1st September onwards, the organisation will be demonstrating in several locations including Parliament Square, reiterating its demands for climate action.
Black Lives Matter Brighton and Extinction Rebellion Brighton collaborated in the protest in recognition that the climate crisis, climate justice and the struggle for social justice championed by Black Lives Matter are deeply interconnected.
Speaking of the aviation sector's contribution to the climate crisis, Claudia Fisher, of Extinction Rebellion Brighton, said:
"The UK is seeking to reduce its greenhouse gas emissions by 100% by 2050, but if demand is unchecked passenger numbers are predicted to rise by 70% and aviation will become the largest emitter of greenhouse gases.
"We can't rely on future technologies to fix this, we have to act now to halve critical rises in global temperature.
"The government has given loan bailouts to airlines totalling £1.5bn since the coronavirus outbreak, with no environmental conditions attached.
"Ryanair is the latest company to secure a £600m loan from the scheme, despite its chief executive, Michael O'Leary's outspoken condemnation of such bailouts across Europe as uncompetitive state aid. British Airways secured a £300m loan and EasyJet received £600m."
A spokesperson from Black Lives Matter explained why the organisation took part in the protest:
"If Black Lives Matter (and especially if All Lives Matter), our government must put an end to the hostile environment and racist, xenophobic, anti-immigration policies.
Deportation flights have still gone ahead in the midst of the Coronavirus pandemic, putting already endangered lives at an even greater risk, and airlines have profited from this.
"British Airways is complicit in the hostile environment and make £30million+ per year from racist deportation contracts with the Home Office.
"There is still no justice for Jimmy Mubenga, whose final words were 'I Can't Breathe' before he was murdered on a British Airways flight while being deported.
"British Airways are yet to investigate his death almost a decade later and continue to profit from deporting Black people and People of Colour to countries where their lives may be in danger."
"If Brighton and Hove is to become an anti-racist city, we cannot have a tower looming over us that stands for racism, xenophobia, and social injustice.
"We cannot have a landmark that represents monetary profit over Black and Brown lives.
"Climate change is already taking its toll on the Global South, and will continue to disproportionately impact Black people and People of Colour all over the world.
"We demand Brighton and Hove City Council end British Airways sponsorship of the i360.
"British Airways are not innocent."
Extinction Rebellion's ultimate aim is to leave a world fit for the generations to come.
Its members are committed to taking non-violent direct action to force the government to put the climate crisis at the top of its agenda.
